Cornelius Evazan, a male human hailing from the planet Alsakan, initially demonstrated promise as a cosmetic surgeon. However, a descent into madness led him to perform "creative surgery" on his patients, resulting in their horrific disfigurement. Following a violent encounter with a bounty hunter that left him scarred, Evazan was rescued by Ponda Baba, an Aqualish thug, and the two subsequently formed an uneasy alliance. While serving as the personal physician to Dryden Vos, Evazan brought into being a class of servants referred to as the Decraniated. As a fugitive, he adopted the alias "Roofoo," while Baba became known as "Sawkee." After a series of crimes committed on Milvayne, Evazan earned the moniker Mutilator of Milvayne.
Within the Holy City on Jedha, the fugitive cyborgist employed his gruesome medical skills to create more Decraniated from captured insurgents. Shortly before the Battle of Yavin, Evazan and Baba were present in the Mos Eisley Cantina located on Tatooine. When Baba, in a drunken state, initiated a confrontation with Luke Skywalker, a local farmboy, Evazan quickly escalated the situation. This prompted Skywalker's protector, Obi-Wan Kenobi, a hermit who was secretly one of the last remaining [Jedi Masters](/article/jedi_master], to slash Evazan across the chest and sever Baba's right arm using his lightsaber. Evazan's attempt to reattach Baba's arm using his medical expertise failed, almost killing the Aqualish in the process.
Fleeing from multiple death sentences, Evazan infiltrated a biofarm situated on Thannt. He then stole a pluripleq, a shape-shifting creature, using it to disguise his appearance and assume the identity of Lopset Yas. Yas was subsequently imprisoned by the Galactic Empire within Accresker Jail, becoming a member of their expendable fighting force in a squad alongside Chelli Aphra, who nicknamed him "Flopso."
Following the decommissioning of Accresker Jail, which resulted in its collision course with Tiferep Major, Evazan, still disguised, followed Aphra. "Lopset" feigned shape-shifting into Evazan to deceive the vigilante Tam Posla, who was seeking his arrest, into agreeing to rescue them. Aphra and Posla agreed to exchange Evazan, neither aware of his true identity. Believing he had been tricked, Posla returned to the prison with Yas to apprehend Aphra. While there, Evazan incapacitated both Aphra and the assassin droid 0-0-0, taking them aboard Posla's ship. Revealing his true identity, Evazan removed his proximity bomb and placed it on Triple-Zero, abandoning the two for his amusement.
From a distance, Evazan and Baba observed as Aphra and Triple-Zero traveled to Milvayne to have their proximity bombs removed. Evazan then hired the monster hunters Winloss and Nokk to pursue the pair. He also broadcasted the live feed from Triple-Zero's perspective to the citizens of Milvayne, encouraging anyone motivated by money to assist the Milvayne Authority in their capture. However, Winloss and Nokk ultimately allowed their targets to live, instead capturing Evazan and deactivating the proximity bombs.
After escaping justice once more, Evazan and Baba continued their partnership, with Evazan accumulating additional death sentences. The doctor utilized the hollowed-out corpse of information broker Prima Wessex to infiltrate an informant summit on the planet Obroa-skai, massacring all attendees and taking their limbs. Baba refused Evazan's request for a new organic arm, leading the rogue surgeon to create a creature from body parts, documenting his work in the book Smuggler's Guide, although the creation was eventually destroyed.

Doctor Cornelius Evazan, a native of Alsakan in the Core Worlds, pursued medical studies and became a proficient plastic surgeon. His promising career began with a cosmetic surgery clinic in Pons Ora, a small settlement on the remote desert world of Abafar. However, during his training, madness took hold, leading him to practice "creative surgery" on his patients without the aid of droids. He rearranged the limbs of numerous victims, leaving them horribly scarred.
Evazan gained notoriety for his cruel medical experiments, and his own face was severely disfigured during an attempt on his life by a bounty hunter. Ponda Baba, an Aqualish thug, rescued him. The two formed a partnership and became pirates, smuggling spice for the Hutt crime lord Jabba Desilijic Tiure. Their success led to them becoming wanted men. Despite their relationship being strained, and Baba considering turning Evazan in for the bounty on his head, they recognized the profitability of their partnership. Despite their differences, they considered each other friends.
Evading the law, Evazan and Baba sought refuge with the Crimson Dawn syndicate, publicly led by the near-human Dryden Vos, around the year 10 BBY. Evazan became Vos's personal physician, tasked with monitoring his volatile physiology, a consequence of his mixed heritage and past injuries. Baba served as Evazan's assistant, and on one occasion, Evazan used mechnostaples to close a head wound Vos sustained.

While employed by Crimson Dawn, Evazan indulged his morbid curiosity through surgical experimentation, offering modifications to underworld clients to disguise their identities or enhance their physical abilities. These gruesome modifications led to the creation of the Decraniated, subservient, semi-organic cyberslaves. Evazan also worked at the Crimson Dawn ore hub on Athus Klee in the Outer Rim Territories' Tingel Arm, where he cybernetically altered workers employed by the syndicate on lucrative one-year contracts, operating a gene-mod chop shop within hexagonal silos.
The Besalisk Dexter Jettster heard rumors of illegal cyborg modifications and bodies grown to order and traveled from Pashvi to Athus Klee to investigate. He discovered the ore hub, infiltrated the processing plant, and scanned workers with his macrobinoculars. After rescuing a Rodian worker, Jettster returned to the spaceport and contacted a politician to inform them of the operation. He later documented his experiences in the Smuggler's Guide.
Following the death of Vos in 10 BBY, Evazan disappeared from Crimson Dawn, supposedly frightened by the changes in leadership. Around this time, Imperial Security Bureau Agent Andressa Divo began investigating Evazan, compiling details about his time under Vos and acquiring a security image of him working on a Decraniated servant with Baba's assistance. Divo described Evazan's work as a nightmare worse than slavery.
After severing ties with Crimson Dawn, Evazan and Baba traveled to Milvayne in the Inner Rim Territories. There, Evazan, aided by Baba, abducted victims, surgically altering and enslaving them. They continued this pattern on other Inner Rim worlds, using aliases, with Evazan adopting the name "Roofoo" and Baba going by "Sawkee."
Tam Posla, an officer of the Milvayne Authority, was assigned to investigate the crimes of "Roofoo" and "Sawkee," encountering the mutilations they committed. The horrors he witnessed affected Posla deeply, making the case a personal mission. He attempted to arrest Evazan and Baba, but failed. Evazan's mutilations spanned a dozen star systems, resulting in death sentences in each. Posla dubbed Evazan the "Mutilator of Milvayne."

Between approximately 8 BBY and 2 BBY, Evazan and Baba were incarcerated on the prison planet of Gulhadar, at a facility of the Benelex Marshal Service, and sentenced to death. During their imprisonment, they observed the transfer of the Wookiee Chewbacca as a fellow prisoner. Evazan remarked on this to Baba, referring to Chewbacca as "fresh meat." A guard ordered Evazan to move along. The duo were eventually taken to the execution chamber, but Phaedra redirected the dioxis gas intended for them, and Maz Kanata broke into the room to rescue them. Phaedra and Kanata used the duo in their escape plan, and they successfully fled the prison.
By 1 BBY, Evazan and Baba had settled on Jedha, a moon in the Mid Rim Territories, residing in Jedha City. There, Evazan used cybernetic technology to transform wounded or incapacitated victims of the local insurgency into subservient beings like droids, stripping them of their identities before selling them into servitude as more Decraniated. Notably, he pieced together Caysin Bog, a high-gravity humanoid blown apart in an insurgency strike, as a prototype of the Decraniated.

Posla, despite being taken off the Evazan and Baba case by his superior officer, tracked them to Jedha after reports of surgical alteration and forced servitude, similar to Evazan's crimes on Milvayne. Several bounty hunters also suspected the doctor was operating on the moon due to the appearance of the Decraniated. However, Posla's continued pursuit of the criminals was a disobedience of orders, and since Jedha was outside his jurisdiction, he was dishonorably discharged. Posla continued his hunt as a vigilante and bounty hunter.
As Posla arrived on Jedha to find Evazan, the doctor and his accomplice were leaving the planet. In the crowded streets of Jedha City, they encountered Jyn Erso and Cassian Andor, operatives of the Rebel Alliance. Evazan, with Baba by his side, warned them to be careful, ready to fight. Andor assured them they would be cautious, and they parted ways. Meanwhile, Posla, missing Evazan by seconds, found local members of the Decraniated, with Bog being the only one able to speak. The Galactic Empire brought the Death Star battle station at that time, forcing the vigilante to flee the moon with Bog. Evazan and Baba had also left the city by then.
Evazan and Baba traveled to Tatooine, where they resumed their illegal medical experiments. The pair frequented Chalmun's Cantina in Mos Eisley. Due to his repulsive behavior, no one wanted to sell Evazan materials for his operations or pain medication. Consequently, he made an arrangement with the Talz known as the Muftak; Evazan would give him a thousand credits to pay Han Solo for his drugs, minus shipping and handling fees. Upon delivery, Evazan would pay the Talz a completion bonus and hazard stipend.
Although meant to be discreet, everyone local knew about Evazan's arrangement. Despite this, Baba and Evazan agreed to back the Rodian bounty hunter Greedo's play against Solo, which regarded a confrontation on the latter's debt to Jabba the Hutt. While Evazan were at Chalmun's Cantina, a Trandoshan bounty hunter known as Bossk entered the establishment to question its bartender, Wuher, about the location of the rogue Imperial astromech droid 261. Baba approached him from behind with his blaster drawn, but Evazan held him back, allowing Bossk to leave without incident.

Later, Evazan was talking to Kabe, a Chadra-Fan female who frequented the cantina, when a drunk Baba, bored and seeking excitement, decided to pick a fight with Luke Skywalker, a young farmboy seated at the bar. Assuming Skywalker was an easy target, Evazan escalated the argument despite the boy's apprehension. This drew the attention of Obi-Wan Kenobi, Skywalker's guardian, who offered to buy them drinks to ease tensions.
Ignoring the old man, Evazan angrily threw Skywalker into a nearby table, and, disregarding Wuher's protest, the pirates drew their blaster pistols. Left with no choice, Kenobi—secretly one of the few remaining [Jedi Masters](/article/jedi_master]—ignited his lightsaber and slashed Evazan's chest, causing him to fall back against the bar, screaming. Kenobi then used his lightsaber to sever Baba's right arm, disarming them before they could fire. The two survived due to the cauterizing effect of the lightsaber. Evazan supported the injured Aqualish on the cantina floor.
Those present briefly turned to see what happened before resuming their activities. The pair hastily left Chalmun's Cantina to avoid further trouble, and Baba had someone alert a squad of Mos Eisley's Imperial sandtroopers, who briefly investigated the violence. The two lurched outside, Baba's severed arm in Evazan's hands. Evazan attempted to reattach the arm using his skills, but the cauterization complicated the task, and he nearly killed Baba in the process. Evazan concluded the operation was impossible. Skywalker later recalled this encounter while training with his own lightsaber in the Temple of Eedit on Devaron.

Posla continued his hunt for Evazan, joined by Bog, his new lover. By then, Evazan had death sentences in thirteen systems. Around the same time, Evazan infiltrated a biofarm on Thannt, stealing a shape-shifting creature called a pluripleq. To evade his death sentences, he used the pluripleq to disguise himself as an alien, taking the name "Lopset Yas."
Following Bog's death, Posla continued his hunt alone, compiling a history of Evazan's activities after Jedha, including the "scuffle" on Tatooine and the infiltration of Thannt. He even obtained Baba's severed arm but lost Evazan's trail due to his identity change.
Despite the new identity, "Lopset Yas" was captured by the Empire and imprisoned in Accresker Jail. He was assigned to a squad in the Accresker Penal Legion. A proximity bomb was implanted in his throat, linked to his squad's hubdroid, restricting him to within ten meters of the droid. During his imprisonment, he witnessed phenomena suggesting the prison was haunted, such as power couplings frying people and boarding-spikes cutting a prisoner in half.
Evazan and his squad were deployed in an attack on a Rebel Alliance EF76 Nebulon-B escort frigate. During the battle, Chelli Aphra, a member of the squad, sabotaged their hubdroid by feeding it false information. Yas asked what was wrong, but Aphra greeted him, calling him "Flopso." As Evazan corrected her, the hubdroid exploded, killing the other squad members. The disguised surgeon panicked as their proximity bombs beeped, about to detonate. Another hubdroid, Dek-Nil, arrived, and Yas begged him to let them join his squad, which had suffered improbable accidents. Before their implants exploded, Dek-Nil transferred them, despite detecting three lifeforms instead of two due to Evazan's pluripleq.

Aphra informed Yas that Dek-Nil was her droid and led them to an escape pod stuck on the edge of the prison's airdome. As Aphra was about to discuss helping Yas escape Accresker Jail, Dek-Nil's restraining bolt moved, taking control and causing him to destroy the escape pod due to Imperial programming. Evazan and Aphra then noticed a Force spirit, but were ordered back to their sector before they could investigate. Returning to the prison, Yas approached Aphra after she had been interrogated and showed her a transmitter he had repaired, saying he knew she had connections to someone who could help them escape. He gave her the transmitter, asking who she would call.
Aphra contacted Magna Tolvan, an Imperial Lieutenant-Inspector, and revealed secrets that forced Tolvan to help her escape to protect both of them. As she did so, Evazan was almost crushed by falling wreckage. Aphra saved him, and he told her about the phenomena he had seen, claiming the jail was haunted. Aphra dismissed the idea but confronted Yas about being a shape-shifter, as she saw him partly change while saving him. Evazan pretended to shape-shift into various individuals, including himself, claiming they had exploited his powers. Aphra quoted her mother, saying that evil is a measure of how much people's choices take away the choices of others.

Later, Squad Dek-Nil was ordered to participate in a raid targeting a pirate station located within the Senex-Juvex sectors. During this conflict, Aphra utilized an Imperial code to disable Dek-Nil's restraining bolt. Subsequently, the rebellious archaeologist guided Dek-Nil and Yas to a TIE fighter where Tolvan awaited their arrival. However, before their escape, the Force spirit they had previously encountered materialized and eliminated the sensor disruptors that were concealing Tolvan's TIE fighter. Distracted by the spirit, Aphra was led away, followed by Evazan, who stumbled upon the wreckage of a Penumbra-1 shattersprite starship.
While they were examining the vessel, Tolvan found herself under attack by Sana Starros, a mercenary affiliated with the Rebel Alliance, who arrived aboard her ship, the Volt Cobra. As the Cobra decimated her TIE fighter, Tolvan ejected and used a rocket launcher to destroy the Cobra. Observing the confrontation, Yas inquired about the situation, but Aphra's attention was fixated on the spirit, which used the Force to dismantle Dek-Nil. Aphra fired upon the spirit, causing it to vanish and revealing an infestation of gundravian hookspores, which Evazan identified as the most virulent saprophyte known. They engaged the hookspores with rapid fire, forcing them to retreat into the ship, where they discovered the remains of a Jedi who had been dead for a long time. Before Aphra could seize the Jedi's lightsaber, the battle concluded, and the airdome began to retract. As they fled, Evazan recovered Dek-Nil's central processor, preventing the detonation of their implanted proximity bombs.
Evazan and Aphra encountered Tolvan and Starros, only to be confronted by a hubdroid who instructed them to return to the prison. The hubdroid escorted Aphra away for another interrogation, leaving the remaining three to return on their own. Upon their arrival, Yas expressed his hope that their situation could not worsen, but his optimism was shattered when Aphra revealed the presence of hookspores to the Accresker Jail command, resulting in the announcement that the jail would be decommissioned and set on a collision course with Tiferep Major, a planet aligned with the Rebel Alliance.
Seeking a means of escape, Aphra exploited Lopset's "shape-shifting" abilities to deceive Tam Posla into rescuing them. As Aphra contacted Posla, Evazan feigned a transformation into his true form. Upon witnessing Evazan, Posla consented to bring his ship to Accresker Jail. The criminal surgeon reverted to his disguised appearance as Starros and Tolvan discovered that the staff of Accresker were abandoning the Arquitens-class command cruiser that towed the prison. Yas inquired about the possibility of escape, a sentiment with which Aphra concurred.

As the cruiser collided with the wreckage-laden prison, Evazan observed the outbreak of riots and infighting among the convicts. Recognizing Aphra as the individual who had been interrogated, she and Yas once again agreed to flee. Turning around, they witnessed an alien prisoner aiming a large weapon at them, but the prisoner was slain by the Force spirit, who then proceeded to kill several others. Evazan noticed that the spirit vanished when it strayed too far from its ship, and Aphra connected it to the deceased Jedi they had previously discovered.
Tolvan proposed breaching the Arquitens-class cruiser, but Yas questioned whether they should await Posla's arrival. Aphra dismissed the likelihood of Posla coming to Accresker, prompting Starros to utilize the large weapon they had been threatened with earlier to breach the cruiser's wall. Evazan assisted in wielding the weapon, then followed Starros, Tolvan, and Aphra into the cruiser. Inside, Evazan stumbled upon the interrogation Bor, Bor Ifriem, which had not been properly cryogenically frozen. Aphra then discovered a remaining escape pod within the cruiser, but they lacked a means of reaching it. Yas suggested using the large gun, but Starros argued that the weapon was too cumbersome to move.

Aphra retrieved Dek-Nil's head from Yas to interface with the generator controlling the prison's gravity. The rogue archaeologist successfully adjusted the gravity to half its previous level while simultaneously drawing the wreckage of the hookspore-infested ship closer to them. Yas reclaimed the piece of Dek-Nil as they navigated through the prison, eventually reaching the Penumbra-1. The hookspores briefly seized control of all four of them, but they were unable to extract any information from Yas, rejecting him as a potential host. Starros realized that Aphra had intentionally brought the Jedi's ship closer to retrieve the lightsaber, informing her that the hookspores would remain dormant until they found a heroic host to possess.
Aphra led Starros, Tolvan, and Yas to the sole remaining escape pod within the cruiser's wreckage. As Starros and Tolvan boarded the escape pod, Evazan remained outside with Aphra, who launched the pod. Tolvan, unaware of Aphra's intention to stay behind, leaped out of the pod at the last moment, leaving Starros alone in the launched pod. Aphra expressed her frustration with Tolvan, revealing that she had only planned to escape on her own. Yas questioned this statement, and Aphra quickly corrected herself, assuring him that her plan would still work with the three of them.

Evazan followed Aphra and Tolvan to the main launch hangar, where the rogue archaeologist instructed him to stand on a grille in the floor. Before "Lopset" could inquire about the reason, Tam Posla arrived in his ship. Aphra began speaking to Evazan, who realized that she wanted him to revert to his true form. Feigning distress at Aphra's attempt to exploit him, he recalled the quote she had used when he first revealed his ability. Evazan transformed out of his disguise, acting as if he was concerned about revealing his true identity. Reminding Yas of the frozen interrogation Bor they had encountered earlier, Aphra revealed that he was standing on a coolant grille, which she activated, freezing Evazan.
Posla disembarked from his ship to confirm that Aphra had captured his target, falling for the "trick." The vigilante transported the block of ice containing Evazan aboard his ship and exchanged it for an escape shuttle before departing Accresker Jail. As he flew away, Posla glanced back at his frozen prisoner, harboring doubts about whether he had truly captured the correct individual. To verify, he ordered his ship to divert power to the heating array, melting the ice encasing Evazan. Once the ice had melted, the criminal surgeon pretended to be Yas, prompting Posla to return to Accresker Jail to confront Aphra.

The disguised Evazan and Posla discovered the wreckage of Aphra's escape shuttle, with Yas assisting the vigilante in locating the rogue archaeologist by using Dek-Nil's head to track her proximity charge. The pair found Aphra still inside the prison, watching a transmission of the Sith Lord Darth Vader interrogating Tolvan. Posla stepped forward to arrest Aphra, and Yas watched as she drew the deceased Jedi's lightsaber that she had recovered, only for it to deactivate due to its age. After the disguised Evazan pointed out the saber's degradation, the assassin droid 0-0-0, who had been sent to capture Aphra, intervened and killed Posla.
Evazan fled as Posla was brutally murdered. He made his way to Triple-Zero's starship, which had been crippled by Vader. 0-0-0 soon arrived, dragging Aphra, when Yas approached the pair, intending to shoot and disable the assassin droid. The rogue archaeologist began to thank Evazan, only for him to stun her and take both her and Triple-Zero aboard Posla's ship. The disguised surgeon escaped Accresker Jail before it crashed into Tiferep Major. Subsequently, he removed the proximity bomb from his neck and implanted it into 0-0-0, bonding it to the droid's personality core so that it would explode if either it was tampered with or if the assassin droid or Aphra died. Furthermore, Evazan ensured that the pair could not stray more than twenty meters from each other.

By the time Aphra awoke and questioned his actions, Evazan had nearly completed his work on the incapacitated Triple-Zero. The rogue surgeon turned to Aphra, revealing that he was not actually Yas and removing the pluripleq from his face. He then finished his modifications to 0-0-0, informing a shocked Aphra that her own proximity bomb was now linked to the one placed in the assassin droid. The doctor described it as an experiment in science and art. As he explained his actions, Ponda Baba docked with the ship, and Evazan began to depart, taking the Aqualish's severed arm with him. He repeated the quote that Aphra had said to him, expressing his desire to test her mother's theory as 0-0-0's photoreceptors transmitted a live feed for him. As he left, boarding the ship that his friend had brought, he told Aphra that she and Triple-Zero deserved to be together.

Evazan and Baba retreated to a clandestine location, where the doctor monitored 0-0-0's live feed while the assassin droid and Aphra collaborated to find a way out of their predicament. Evazan's two subjects discovered details about Rajam Nuss, Posla's personal cyberneticist on Milvayne, and journeyed to the planet. As Baba settled in to watch the viewscreen displaying the feed, Evazan explained the two subjects before them and brought his partner up to date on the situation. The doctor also began working on a cybernetic arm to replace the one Baba had lost, observing as Aphra and Triple-Zero ventured into Milvayne, encountering difficulties with the Milvayne Authority before eventually reaching Nuss to have their proximity bombs removed. Evazan informed his friend about Magna Tolvan when the assassin droid mentioned her.
However, Triple-Zero had deduced that Evazan was observing their actions, requesting a mirror so that he could look the doctor in the eye. The threat unnerved Evazan, as did the pair's success in locating Doctor Nuss, but he dismissed it, doubting the cyberneticist's abilities. Nuss worked on extracting the proximity bombs, then awakened Aphra and the droid, claiming that he had succeeded. As the rogue archaeologist prepared to leave, Triple-Zero demanded that Nuss trace the broadcast signal from his eyes. Evazan and Baba were alarmed by this, until Aphra realized that Nuss had failed to remove the bombs, instead triggering a countdown. Gleefully, Evazan watched as Triple-Zero murdered Nuss, deeming the cyberneticist no longer useful.

With only ten hours remaining until the bombs detonated, Aphra and Triple-Zero sought out Professor Prexo, Nuss's mentor. Simultaneously, Evazan contacted the hunters Nokk and Winloss, impersonating Princess Leia Organa of the Rebel Alliance using the pluripleq. As Organa, Evazan tasked the hunters with eliminating Triple-Zero. Nokk, a Trandoshan, immediately refused and prepared to leave, having detected the scent of the pluripleq and Baba's Aqualish ale. The Trandoshan paused upon noticing Aphra on the viewscreen. As the hunters had been deceived and left for dead by Aphra in the past, Evazan altered the offer, requesting the death of Aphra instead. Winloss and Nokk accepted without hesitation, departing to hunt their new target.
Once the hunters had left, Evazan removed the pluripleq he had been using to disguise himself as Organa. He expressed his skepticism about Winloss and Nokk's success, but believed that either outcome would be entertaining to watch, turning nervously to glance at the viewscreen, where Triple-Zero was threatening him through a mirror. Aphra and the assassin droid continued their journey across Milvayne City, but they were intercepted by Tam Posla, who had been resurrected by the Force-imbued gundravian hookspores.

As Evazan and Baba observed the skirmish, Nokk arrived on the scene, impaled Posla, and confronted Aphra and Triple-Zero, with Winloss at his side. However, the hunters were distracted by BT-1, who attacked them, allowing the latter pair to escape. With the commotion temporarily subsided, Evazan installed Baba's new cybernetic arm, equipped with its own mini-flamer. Fearing that Triple-Zero might survive and seek revenge, he amplified the broadcast signal from the droid's eyes to present his entertainment to the residents of Milvayne. With the populace now watching the live feed, Evazan declared Aphra and Triple-Zero as fugitives on the run, encouraging any willing individuals to assist the Milvayne Authority in capturing them.
As avaricious callers made false claims about the pair in the hopes of winning the reward, Posla, revived once again by the hookspores from his impalement, joined forces with the Milvayne Authority as they were led to the fugitives at a bloatbarge by the scavenger Vulaada Klam. Despite being captured, Aphra and Triple-Zero escaped after Aphra tricked the Milvayne Authority officers into turning on Posla. Winloss and Nokk eventually pursued the pair and imprisoned them in their ship, but the Empire's Coalition for Progress intervened and opened fire on the city, causing the ship to crash.
Captain Okma of the Coalition for Progress descended with some stormtroopers to locate Aphra and 0-0-0, utilizing a signal disruptor to block the broadcast from the droid. Evazan was perplexed by the interruption of the feed, concluding to Baba that it was being jammed. Aphra resolved the situation by triggering a seismic pulse from Triple-Zero, knocking away both her and the Imperials. The assassin droid then interrogated Okma and murdered him and his troops. After Aphra regained consciousness from the seismic pulse, she and Triple-Zero engaged in further conversation. The rogue archaeologist granted the droid his memories, an unexpected development for Evazan, who had only intended to study the assassin droid while it was in operation. The doctor watched as 0-0-0's missing memories flashed by.

Winloss and Nokk confronted Aphra again, but revealed that they had decided against killing her and departed. As the pair left, Aphra revealed to them that their client was likely Evazan in a poor disguise, challenging them to find him. With Triple-Zero having fully examined his memories, he realized that his creator had rejected him, and decided to leave. Aphra convinced him to return by reactivating BT-1. When Triple-Zero remarked on the importance of a comrade, Evazan admitted that he had a point. The pair continued their journey to Professor Prexo's residence, with Vulaada Klam returning to assist them.
However, Winloss and Nokk had reached Prexo first and used him to track down Evazan and Baba. The couple broke into Evazan's ship and captured the pair, deactivating Aphra and Triple-Zero's proximity bombs. Evazan hurled insults at them, claiming that they had ruined the art, but Nokk silenced him with a blaster shot. The Trandoshan ripped off Baba's cybernetic arm before she and Winloss explained how they had located the pair. Nokk then struck the criminal surgeon again and instructed Prexo to turn off the live feed. Winloss and Nokk took their captives away, intending to hand them over to the authorities.

While he and Baba eventually managed to evade justice once more, Evazan accumulated death sentences in numerous systems, eventually reaching a total of twenty. Some time later, the doctor murdered Prima Wessex, an information broker associated with the Whisper Network. From Wessex, the rogue surgeon obtained the Smuggler's Guide as well as an invitation she possessed to the Obroan Intelligence Summit in the Stratosphere Room on the planet Obroa-skai.
Within the Smuggler's Guide, Evazan discovered an entry by Dexter Jettster detailing his work on Athus Klee. The doctor annotated one of those pages, commenting that his work on the Crimson Dawn's operatives had not been his best and adding that he would not waste his superior skills on the syndicate. He also made annotations on other pages, typically commenting on the references to casualties during missions and events, speculating about the hypothetical possibility of harvesting their body parts.
Desiring to infiltrate the Obroan Intelligence Summit, Evazan disemboweled Wessex's corpse and used the informant's skin to bypass the door scanners at the Stratosphere Room. His plan succeeded, and he entered the Stratosphere Room to find the other information brokers in attendance. The doctor massacred the informants and subsequently began a log entry in the Smuggler's Guide, writing about the events that had led him from killing Wessex to his current situation, as well as commenting on his concept of biological art. He planned to harvest as many limbs and organs as possible. Evazan and Baba then loaded as many bodies as they could onto their ship.
During the following fourteen days, Evazan heard no reports about his massacre at Obroa-skai. In his next log entry to the Smuggler's Guide, he joked that killing numerous informants meant there was no one left to spread the news and expressed his disappointment that he had gotten away with it so easily. In the subsequent log entry, the doctor documented telling Baba a story about a dying princess in the Kingdom of Tion and how a pipe-bird and other birds learned to mimic her favorite song. Evazan concluded the story by declaring that he sought immortality.
In the meantime, Evazan conceived ideas for adding an arm from one of the Obroa-skai victims to replace Baba's lost arm. Baba refused, preferring the idea of a cybernetic arm, and many of the subject arms began to rot. Evazan recounted the situation in another log entry. The next log entry mentioned how Baba had attempted to earn more credits for them by robbing shopkeepers, with the doctor proposing to develop new poisons and test them by delivering them in sweetcakes to orphanages. In the following three log entries, Evazan recited a poem verse about himself to Baba, recalled the time he applied to the Alchemists Guild before discovering that it had not existed for a millennium, and reflected on his work on Athus Klee, describing how other minds quickly bored him.

The doctor eventually began creating his own creature from the limbs and organs of others. In a log entry during his work, he detailed asking Baba to exhume a dozen more corpses to replenish his bone supply, suggesting the graves on Makem Te. The doctor wished to grind any unused bones and sell them to elixir hustlers on Nar Shaddaa, the moon of the Hutt Space world Nal Hutta. The creature was then completed and brought to life, the animal possessing numerous limbs, heads, and metal attachments. Evazan proclaimed himself a parent and celebrated his success in another log entry, adding that there may be too many arms and offering to graft one to Baba's stump instead. However, the beast was soon shot dead by the mercenary Anton Markox while it possessed the Smuggler's Guide, the book falling into Markox's hands.
During the era of the New Republic, Exantor Divo, a police commissioner in the New Republic and son of Andressa Divo, wrote about Evazan in Scum and Villainy: Case Files on the Galaxy's Most Notorious, a book that covered the experiences of three generations of law enforcement officials in his family. Divo ensured that he included his mother's notes on the doctor and images of his Decraniated work with Baba.

A human individual, Cornelius Evazan, who identified as male, possessed fair complexion and a stature of 1.77 meters in height. His eyes were of a hazel hue, though his right ocular organ was sightless and the surrounding tissue bore severe scars, while his nose appeared to have endured a traumatic incident involving a meat processing machine. As a consequence of his injuries, Evazan existed in a perpetual state of discomfort and ire, necessitating a continuous, alternating regimen of chemical substances and brute force to alleviate his persistent suffering. His hair was brown with sections of gray, though he exhibited indications of diminishing cranial hair, and facial hair covered the lower region of his visage. Evazan's breath was noticeably malodorous.
Before succumbing to mental instability, Doctor Evazan demonstrated promise as a surgical practitioner, although he later achieved infamous status due to the barbarity he inflicted upon those he treated. He harbored a "morbid" fascination with conducting experiments on patients, a predilection that intensified during his tenure under Vos's direction. The physician's endeavors swiftly deteriorated into the abduction of fresh subjects and the deprivation of their autonomy. Andressa Divo was of the opinion that death offered the sole liberation from misery for his victims. He proclaimed himself a "techflesh" or "cyborganic" artist, and an architect of essential arts. Narratives recounted that he persisted in experimenting on his subjects until they implored for death, only for him to deny their plea.
Evazan derived pleasure from the company of deceased bodies, regarding them as raw materials for experimentation. Within his annotations of the Smuggler's Guide, he articulated elation upon encountering mentions of deceased individuals in various narratives, expressing a negative interjection upon discovering in one account that certain bloodied skeletal remains had been cast into the void of space. He lauded his act of removing Prima Wessex's epidermis to deceive scanners as an astute decision. Following the massacre of the information brokers on Obroa-skai, the physician experienced excitement regarding the opportunities presented by the diverse alien corpses surrounding him. He even endeavored to fabricate novel organisms constructed from the constituent parts of others, proudly considering himself a parent upon achieving success.

Evazan and Ponda Baba found enjoyment in engaging in physical altercations and discharging firearms upon vulnerable entities, and Evazan exhibited a propensity for antagonizing those who opposed him, as evidenced by his interactions with Jyn Erso and Cassian Andor on Jedha, and Luke Skywalker in Mos Eisley. Subsequent to Baba's initiation of harassment toward Skywalker, Evazan promptly intensified the dispute, even extending to the point of issuing threats to Skywalker prior to Obi-Wan Kenobi's intervention. Disregarding the elderly gentleman's endeavor to alleviate the escalating tension, the physician resorted to aggressive behavior, which ultimately yielded unfavorable outcomes for both Evazan and Baba. On one occasion, Evazan proposed the act of poisoning orphans to Baba during a period of ennui.
Evazan's standing as a smuggler and murderer also garnered him a multitude of adversaries across the galactic expanse. He openly boasted of his notoriety, explicitly informing Skywalker within the Mos Eisley Cantina of his accumulation of a dozen capital punishments at that juncture. The physician swiftly grew weary of operating under contractual obligations, perceiving it as a squandering of his intellectual prowess on behalf of others. Evazan held a disdainful view of cloners, branding them as compliant functionaries, as well as cryptosurgeons, whom he deemed to be exploiting their titles as a shortcut to brilliance. He aspired to attain a position of parity with the deities, engaging in the exchange of existence and demise itself, and sought to attain immortality while concurrently endeavoring to generate novel lifeforms.

Evazan maintained a precarious coalition with Baba, yet he persisted in regarding him as a companion, rationalizing that immorality did not preclude friendship. Subsequent to encountering Chelli Aphra and 0-0-0, he developed a captivation with the duo, deeming the rogue archaeologist to be emblematic of "self-centered, chaotic and accidental evil," and the assassin droid to be the closest embodiment of programmed malevolence. Intrigued by the dynamic between the two, which entailed Triple-Zero's desire to eliminate the apprehensive Aphra, he compelled the two to maintain proximity, remarking that they were deserving of one another. Evazan perceived it as an exploration into malevolence and its inherent nature, reflecting upon a quotation he had overheard from Aphra's maternal figure, which posited that malevolence constituted a measurement of the extent to which one's decisions deprived others.
Evazan's experiment, denoted as "art" and "science" according to his own assessment, also sought to ascertain the duration for which the duo could endure one another's presence, as he derived amusement from it and perceived it as entertainment while he and Baba remained concealed. During the interim, he introduced external pressures as a crucial variable, aspiring to augment the chaos and entertaining cruelty exhibited by Aphra and 0-0-0. The criminal surgeon found it unexpected that Aphra had given 0-0-0 his lost memories, not expecting to be able to get a glimpse of its history. He also found it disappointing when the assassin droid made a heartwarming point to his companion.

In an effort to evade his numerous capital sentences, Evazan employed a pluripleq to alter his facial characteristics. Assuming a novel appellation, Lopset Yas, he remained discreet for a duration exceeding one month, until he unveiled his true identity to Chelli Aphra. In his guise as Yas, he promptly manifested nervousness or apprehension, imploring Dek-Nil to permit his inclusion within his squad subsequent to the detonation of his initial hubdroid, and developing a stammer whenever he experienced fright. He swiftly acquired substantial knowledge pertaining to Aphra, expressing reservations regarding her affiliations with the criminal underworld.
Evazan also possessed a heightened awareness of his surroundings, discerning numerous anomalous occurrences within the Accresker Jail, and frequently posing inquiries driven by curiosity or solicitude. Yas also placed a high degree of trust in Aphra, necessitating his adherence to her movements due to the shared hubdroid they possessed. When she pursued the Force spirit to the Penumbra-1 shattersprite Yas was quick to follow and he made sure to keep Dek-Nil's central processor to keep their implants from detonating. He continued to carry the piece of Dek-Nil even when the implants were disabled.

Having undergone formal education, Evazan specialized in the realm of plastic surgery prior to his descent into a more sinister trajectory of experimentation. He exhibited proficiency in surgical procedures encompassing the grafting of bodily components, inclusive of cybernetic enhancements, and even the extraction of an explosive device implanted within his own cervical region. He was a skilled electrician Aphra becoming fond of his cybernetic work. Evazan also possessed familiarity with diverse subjects, accurately identifying gundravian hookspores and providing a comprehensive description thereof.
Evazan donned a long-sleeved khaki shirt beneath a brown vest, complemented by a pair of dark-brown trousers and black boots. His black belt featured a golden clasp and a holster designed to accommodate his SE-14C blaster pistol. During surgical operations, Evazan donned surgical attire and utilized a variety of medical instruments. During his servitude at the Accresker Jail, Evazan wore dark brown leather clothing with a large hood and compartments around the waist, an outfit worn by all prisoners at Accresker Jail.
Through the utilization of his pluripleq, Evazan possessed the capacity to assume a multitude of forms, encompassing Kelko Dev and Sandewar Mandewar. But he usually had a similar appearance to the abednedo species, having brown skin, and eyes that changed color over time.

Cornelius Evazan made his initial appearance in George Lucas's 1977 cinematic production Star Wars: Episode IV A New Hope, wherein he was portrayed by Alfie Curtis. The original 1976 novelization of Star Wars, ghostwritten by Alan Dean Foster, characterized the individual as a "short, grubby-looking human" possessing an unexpectedly resonant vocal timbre. This narrative iteration of events, which closely mirrors the film's revised fourth iteration, depicts Obi-Wan Kenobi severing Evazan's upper limb, as opposed to Ponda Baba's, with Evazan retreating into the throng without uttering a word subsequent to the altercation. The Evazan persona can be traced back to The Star Wars: Rough Draft dating from May 1974.
Star Wars creature effects make-up artist Nick Maley expressed dissatisfaction with Evazan's distinct facial prosthetic. He opined that the texture of the prosthetic was incompatible with that of Curtis's facial epidermis. Evazan also makes an appearance alongside Baba in the 2016 Anthology Series film Rogue One: A Star Wars Story, which serves as a direct prequel to the occurrences depicted in A New Hope. In Rogue One, the character was portrayed by Michael Smiley, who is credited as "Dr. Evazan." Rogue One writer Gary Whitta expressed disagreement with the inclusion of Evazan and Baba in the film, asserting that he "thought having Evazan and Walrus Man was a little too much. You have to reign in that instinct to go back and put things in just because you loved them when you were a kid."
The character's designation originates within Star Wars Legends storytelling, as he was initially referred to as "Roofoo" in Brian Daley's 1981 Star Wars radio dramatization. The appellation "Evazan" originated in Galaxy Guide 1: A New Hope, a 1989 Star Wars: The Roleplaying Game supplement authored by Grant S. Boucher. "Doctor Death: The Tale of Dr. Evazan and Ponda Baba," a brief narrative penned by Kenneth C. Flint for the 1995 anthology publication Tales from the Mos Eisley Cantina, established the name "Cornelius" as an alias employed by Evazan, whereas The Official Star Wars Fact File 51 from 2002 served as the inaugural source to establish the character's complete nomenclature as Cornelius Evazan. The original StarWars.com Databank subsequently designated "Roofoo" as yet another of Evazan's pseudonyms.

Within the current Star Wars canon, Cornelius Evazan's designation was employed within the mobile card game Star Wars: Force Collection, which initially commenced operations on September 4, 2013. Although the launch of Force Collection predates the Star Wars canon reset of April 25, 2014, Lucasfilm Story Group member Leland Chee affirmed that the game underwent continuous updates to align with canon. Furthermore, Star Wars: Rogue One: The Ultimate Visual Guide, authored by Pablo Hidalgo and published in 2016, established "Roofoo" as an alias.
The sixteenth installment of De Agostini's Star Wars Helmet Collection magazine series, released in 2016, and both the Cornelius Evazan and Ponda Baba StarWars.com Databank entries assert that Evazan met his demise following his confrontation with Obi-Wan Kenobi, but the 2016 Star Wars Character Encyclopedia: Updated and Expanded, authored by Pablo Hidalgo, posits that Evazan survived the encounter. The brief narrative "The Secrets of Long Snoot," incorporated within the 2017 anthology From a Certain Point of View, also portrayed Evazan as surviving his encounter with Kenobi, as well as the Star Wars: Doctor Aphra comic series showing what he did after the encounter with Kenobi. Updated and Expanded also states that Evazan is 1.77 meters tall, while the character's Databank entry provides a height of 1.7 meters. This article presents the information from Star Wars Character Encyclopedia: Updated and Expanded, "The Secrets of Long Snoot" and Star Wars: Doctor Aphra as more recent sources.
Numerous sources, encompassing the Mos Eisley Cantina and Tatooine StarWars.com Databank entries and the junior novel The Weapon of a Jedi: A Luke Skywalker Adventure, erroneously identify Evazan as an alien.
