Royce Hemlock

Royce Hemlock was a human male who was an officer in the Galactic Republic's science corps. He was expelled due to his unorthodox experiments, but became acquainted with the Kaminoan Chief Medical Scientist Nala Se, whose talents he praised. Eventually, Hemlock found Emerie Karr, a female clone of the bounty hunter Jango Fett and she became his assistant.

Around 18 BBY, Doctor Hemlock was a chief scientist of the Advanced Science Division assigned to work on the Imperial cloning program on an Imperial medical laboratory on Setron. There, Hemlock began experimenting on clone troopers assigned to the facility, including clone cadets, by collecting blood samples for them in search of an individual with a high midi-chlorian count as part of Project Necromancer. In addition to Hemlock's research on Project Necromancer, he also created slither vines, an experimental bioweapon. The vines ultimately broke containment and overran the facility, forcing Hemlock to evacuate and order a bombardment of the facility to destroy it.

Soon after the disaster on Setron, Hemlock moved his operations to Tantiss Base on the planet Wayland. Following the Empire's attack on Kamino, Chief Medical Scientist Nala Se was moved to the facility to work on Project Necromancer under Hemlock.

Hemlock would also select bounty hunters with capturing subjects with high M-counts and had them delivered to Tantiss for experimentation. Dr. Hemlock also ran a secret program to condition several clones into assassins to perform assassinations and other covert operations.

Soon after, Hemlock visited Kaminoan scientist Nala Se, who was being held in a cell due to her refusal to participate in any of the Empire's cloning operations. While Hemlock praised Se's work as a cloner, he chastised her unwillingness to contribute to the Imperial cause. When Se further refused to cooperate, Hemlock threatened that he could have far worse done to her. As he left the Kaminoan to ponder her decision, Hemlock was approached by Emerie Karr and informed of the loss of communication with transport 904, an Imperial transport associated with the cloning program. Hemlock ordered recovery teams to be sent out and the transport's asset to be quickly contained. He inquired about any other Kaminoans that happened to be taken off-world prior to the destruction of Kamino, in which Emerie confirmed that the planet's former Prime Minister, Lama Su, was being held on Coruscant. Hemlock ordered Su to be brought to him.

Karr later informed Hemlock that transport 904's asset, a cloned Zillo Beast, had been recovered and secured in Mount Tantiss. As Hemlock walked to the base's docking bay with Imperial clone commando Scorch to observe the arrival of Su, he was informed by the commando that any witnesses to the Zillo Beast clone were detained and would be dealt with, while also that a rogue military vessel was present during the operation. Hemlock tasked Scorch with tracking down the vessel as Su arrived. Hemlock informed Su that he has had trouble securing Se's cooperation, while Su mocked the Imperials for their lack of expertise in regards to cloning. Hemlock proposed Su's freedom in exchange for information on how to motivate Se, causing Su to reveal the existence of a female clone that Se had doted upon, and that she would be the key in securing the Kaminoan's cooperation. Satisfied, Hemlock invited Su into the facility for further discussions.

Following an incident on Barton IV, which included the murder of his commanding officer, CT-9904 "Crosshair" was brought to Mount Tantiss. As Hemlock entered the operating chamber, he mentioned that Crosshair healed quickly after the critical condition when he first arrived. Hemlock told Crosshair that he was not sent in for punishment, but rather to give him a second chance. Hemlock asked for his cooperation to help locate Clone Force 99, adding that the clones possessed something he needed. Crosshair quickly guessed that Hemlock wanted Omega and told the doctor that they would never give up the kid. Hemlock said that the kid was a clone, which made her Imperial property. Crosshair responded that he did not know where the rogue clones were, but Hemlock replied that, the clone being a former member of the team, he knew how they operated and thought. Crosshair did not cooperate further, and Hemlock sent in an IT-O Interrogation Unit to torture the clone until he broke. As the interrogation droid started to torture Crosshair, Hemlock was notified by Scalder that one of their transport ships from Balmorra was attacked, and the prisoners aboard escaped. Hemlock told Karr to inform him when Crosshair was ready to talk and left the chamber.

Crosshair soon attempted to escape but was stopped by a toxin gas after he entered terminal three. Hemlock then entered the terminal, inhaling the toxin deeply without issue before telling Crosshair that the toxin was his own special formula and that he had built an immunity to it. After the failed attempt to escape, Crosshair was put back in the operating chamber.

Hemlock later informed Governor Wilhuff Tarkin via hologram that the attack on the transport ship was unfortunate but inconsequential, although Tarkin thought it was still a concern. The governor warned him that the stolen data could compromise the location of the facility, to which Hemlock said that there were various protocols in place to prevent that. Despite Tarkin's warning, Hemlock was more concerned with how the transport ship was targeted. Tarkin suspected that the leak came from rogue clones still within the Imperial Army, adding that a growing number of clones had been questioning their orders. Hemlock responded that decommissioning problematic clones would not eliminate the threat. Hemlock proposed that the clones be sent to him and that he could deal with them in other ways. Interested, Tarkin told Hemlock that he expected a full briefing about his plans at the summit, before he ended the transmission.

Hemlock later returned to the operating chamber where Crosshair was held, but the clone continued to remain silent. Hemlock tried to tease Crosshair with potential freedom if he helped locate the rogue clones, but to no avail. Annoyed, Hemlock told Karr to increase the injection level of the interrogator droid. The interrogator droid soon came into view and started the torture on Crosshair, and Hemlock smirked as he stood and watched.

Hemlock went to Raven's Peak, an Imperial fortress on Eriadu, as he was invited by Tarkin to present his plans on what he wanted to do with clones. As his shuttle landed on the docking lane, Hemlock walked out and two TK stormtroopers told the doctor that Tarkin expected him and guided him to the summit. When Hemlock entered the meeting room, Tarkin and a few other top ranking officers were already waiting for his arrival. Tarkin told Hemlock that he was late to which he responded that there were other matters that required his attention, they then started the summit.

General Hurst Romodi advocated a phased, widespread deployment of stormtroopers to ensure a secure military presence across all sectors. Tarkin disagreed and advocated for a comprehensive strategy for galactic unification to deter dissent and rampant "self-interest." Tarkin then asked Hemlock what progress in the Advanced Science Division he had made with cloning, and Hemlock insisted their cloning efforts were of great interest of Emperor Palpatine. He was eager to unlock the secrets of the Kaminoan's research and build upon it. Tarkin questioned how long these advancements would take, as the project required extensive funding. Hemlock replied that science could not be rushed and that he had found a new purpose for the decommissioned clone troopers, whom he described as test subjects.

When Romodi asked if the clones had consented to his experimentation, Hemlock countered, saying that the clones were Imperial property, and that their consent was not required. Romodi warned there were many people in the Imperial Senate who were fighting for clone rights and them uncovering news about Hemlock's secret operation could hurt Hemlock's cause, but the doctor was unconcerned, as the location and operations under his command were top secret and far from the eyes and ears of the Senate. Barton Coburn then brought forth his concerns, warning Hemlock that the clones are cunning and loyal warriors and questioning the willingness of his peers to cast them aside. Coburn asked Hemlock what would happen to any clone who discovered the truth of what was happening and took up arms against the Empire. Hemlock acknowledged some have already done that and Tarkin backed him up, citing any clone uprisings would be answered with swift and unilateral action.

Unbeknownst to Hemlock and the rest of the Summit, The Bad Batch, as well as Saw Gerrera and members of his Partisans, had infiltrated the fortress. Gerrera and the Partisans planted several detonators on the lower levels of the fortress in an attempt to destroy it and the Imperial officers located there. Meanwhile, the Bad Batch was attempting to discover the location of Hemlock's base by planting a homing beacon on Hemlock's shuttle. The facility was placed under lockdown, sealing off the command room from the rest of the compound for their protection. Shortly afterward, Gerrera and the Partisan escaped in a Nu-class shuttle, detonating the hanger bay and destroying all the other shuttles as they left, including Hemlock's. The Bad Batch were able to escape, but one of their number, Tech, sacrificed himself to allow his squad to make it out.

The Bad Batch returned to their old base of operations, namely Cid's Parlor on the planet Ord Mantell. While the medical droid AZI-3 tended to their wounds, Cid sold them out to the Empire. Venator-class Star Destroyers arrived shortly after Cid informed Wrecker of her betrayal. While Omega and AZI fled, Wrecker was quickly taken prisoner by Hemlock and his clone commandos. Hunter confronted Hemlock, who told him he was outnumbered. He thanked Cid for her assistance, giving her the payment before ordering her to leave. Omega and AZI silently watched from above as Hunter was surrounded. Hemlock offered to spare Omega's life if Hunter and Wrecker both surrendered to him. He then tossed Hunter Tech's damaged goggles as a "gift." After threatening to kill Wrecker if Hunter did not stand down, Hunter relented, placing down his DC-17 blaster pistol and allowing the clone commandos to place stuncuffs on him. A clone commando reported to Hemlock that the girl was not in the parlor's office, to which Hunter replied that she was long gone.

As Omega and AZI fled Cid's Parlor, Hemlock led his troops and prisoners though the streets of Ord Mantell. As Omega fired her energy bow at the convoy, Hemlock instructed his clone commandos to lower their weapons while he addressed Omega. Omega demanded he release Hunter and Wrecker, but Hemlock offered a trade. If she surrendered, he would spare her friends. He claimed Nala Se needed Omega's help. Hunter said that the Kaminoans were all dead, but Hemlock assured him that Nala Se was alive and well cared for, as Omega would be. Omega rejected Hemlock's offer, but, even as Hunter tried to warn her, Scorch snuck up from behind and stunned her. Hemlock then ordered his troops to search the city for Echo and bring all three of them back to Eriadu, so Tarkin could interrogate all of them personally.

While AZI and Echo hijacked an All Terrain Armored Cannon, Hunter and Wrecker freed themselves, using the diversion to escape from their captives. Simultaneously, Scorch carried an unconscious Omega as he and several clone commandos followed Hemlock to his shuttle and departed Ord Mantell. The Bad Batch attempted to thwart Hemlock's departure, but his remaining forces prevented them from rescuing Omega.

Upon Hemlock's shuttle's arrival at Mount Tantiss, they were greeted by a contingent of clone commandos escorting Scalder and Nala Se. Hemlock told Scalder and the commandos to escort Omega to Emerie Karr to care for her injuries. Meanwhile, Hemlock spoke with Nala Se, reminding her Lama Su spoke highly of her attachment to Omega. He asked her to reconsider working on the Emperor's project. Hemlock told her to make it possible as Omega would suffer if she did not follow his commands.

The Bad Batch would eventually arrive on Tantiss due to Rampart's assistance, who had brought them to Imperial Station 003. When Scorch informed him of the intrusion, Hemlock immediately had starfighters scrambled to patrol the airspace. The patrols eventually ran into the stolen shuttle and managed to shoot it down. Hemlock then had foot patrols scour the surrounding area, knowing that the rogue clones were likely alive. The patrols were not able to capture the clones, but they did find Rampart, who was thrown into a cell.

Hemlock decided to speak with Rampart, who was insistent that the folly of letting rogue clones discover the locations of Tantiss would embarrass him in front of the Emperor. Hemlock believed that he did not understand the importance of his projects and that because of them, he was indispensable to the Empire. After Omega freed the Zillo Beast clone, it wreaked havoc and broke out of the facility, and Hemlock ordered patrols to track the beast down. The doctor later activated four more clone assassins to help CX-2 capture the rogue clones.

Hemlock had the clones being held in captivity, personally watching Hunter being electrocuted. He ordered the voltage stopped, and Hemlock told him that during their last encounter, he had lost a squad member. As such, he told him that he would lose another member, but Hunter defiantly told him that he was the one going to die before Hemlock had the voltage resumed. Governor Tarkin contacted Hemlock in regards of the Zillo beast breaking out and resulted in him deciding to visit the facility, despite Hemlock's persist that he had the situation under control. Echo and the other freed clones soon began fighting Hemlock's troopers, while Omega worked to free her brothers. Hemlock was able to catch her, claiming that the clones' loyalty to each other was their weakness, but Omega had freed Wrecker in time, who then helped Hunter and Crosshair out before entering the fight with other clone assassins.

Along with Scorch, Hemlock flagged a CX Dagger vessel to try escaping the facility, but it was shot down by Crosshair before the two clones killed Scorch. With few options, Hemlock threatened to kill Omega before positioning himself on the edge of the railing, knowing that she would fall alongside him if he was shot. With his attention focused on the clones, Omega managed to stab him, allowing Crosshair to shoot the shackle binding them together. The two clones then shot Hemlock multiple times, who then fell off the railing to his death. Tarkin would eventually arrive and find the facility heavily damaged and the databanks regarding Project Necromancer destroyed. He then ordered the facility be shut down indefinitely and all remaining funds to be relocated to Project Stardust.

Despite Hemlock's death and the discontinuation of Project Necromancer, the project would come back into prevalence during the New Republic Era. Imperial Remnants would continue work on the project, where Commandant Brendol Hux would assume leadership in place of Hemlock. During a meeting amongst the Shadow Council, Brendol brought up the project and explained how its cloning capabilities would introduce new leadership into the Remnants.

While Hemlock is a soft-spoken and seemingly courteous man, he is in reality an extremely twisted individual. He displayed an ambitious, work-oriented mindset and was eager to begin his service in the Imperial cloning program. He was willing to use intimidation and the threat of torture to get those that opposed the Empire to do his bidding. Hemlock spoke in an even tone and was often composed. He directly oversees some of the most bizarre and inhumane experimentation within the Empire, ranging from simple cloning to creating living bio-weapons. He uses the decommissioned clones as living test subjects, performing many painful experiments on them that they often do not survive. Like all Imperials, he despises clones, viewing them as nothing more than property; as such, he relishes in any opportunity to make them suffer. Much like Pong Krell and Lieutenant Nolan, he’s insistent on referring to clones by their numbers instead of their chosen names as a sign of disrespect. However, like Krell, he is willing to address clones by their names if they are loyal enough to him, as is the case with his second-in-command Scorch.

He is efficient and never raises his voice, and is always in control of the situation, and remains calm even when things don't go to plan. He is also, in spite of his quiet demeanor, a monstrous sadist, taking dark enjoyment from the suffering his work brings, and is all too happy to threaten anyone with torture. His methods are so extreme that even most of his fellow Imperials view many of his experiments as abominations. He has shown to admire the sadism of other individuals as he expressed to Crosshair his admiration towards his insubordination when he shot and killed his commanding officer.

There is nothing he won't do in order to achieve his goals, and the lengths he'll go to do so are immense. These include but are not limited to; arresting and executing innocent civilians en masse, ordering the kidnapping and harm of children, and as stated above, horrific torture of prisoners. Hemlock is a foreboding and sinister new Imperial leader actively working to bring about the demise of any surviving clones following the Clone Wars and the rise of the Empire.

Unlike other Imperials, Hemlock seems to genuinely believe that scientific advancement is the key to the Empire's control as opposed to sheer military strength. As such, he is willing to take his time and give his enemies short-term victories in order to achieve his long-term goals. That said, Hemlock is also motivated by the same desire for personal advancement as most other Imperials. He strives towards the position of scientific minister and courts the Emperor's favor by dedicating himself to Project Necromancer, an endeavor that most within the Empire would consider abominable.

Despite his calm demeanor, Hemlock is ultimately proven to be a coward, as he tries to kill Omega in his final moments and barks at Hunter and Crosshair to drop their blasters.

Royce Hemlock was a human male with dark brown hair that had been neatly slicked back, blue eyes, and light skin. Hemlock displayed a habit of holding and tending to his left hand, which was covered with a glove.

Royce Hemlock first appeared in the second season of Star Wars: The Bad Batch episode "Metamorphosis," voiced by Jimmi Simpson. However, his appearance was first hinted at in a post by Sean Kiner as part of a series of cryptic tweets that hinted at upcoming Bad Batch episodes. Although the post was meant to be a pun on Hemlock's name, the image they used was the wrong plant.
