Kix

CT-6116, also known as "Kix," was a clone medic in the Grand Army of the Republic. Early in the Clone Wars, the Jedi became increasingly desperate to capture the commander of the Separatist droid army, General Grievous. After a battle above the planet of Saleucami, he was forced to jettison from his ship in an escape pod, landing on the planet's surface. In an attempt to capture the general for good, Obi-Wan Kenobi gathered a group of clone troopers, including Kix, in order to follow them. The clones eventually discovered the wreckage of the ship, with Cody noting and subsequently reporting to Kenobi that it had crashed recently. Kenobi decided it would be best to split the group into two teams, and left Rex, along with Kix, Jesse, and Hardcase to search for the other missing escape pods, while he, Cody and Crys stayed behind to further investigate the crashed ship.

Each mounting their own BARC speeders, Kix's team searched the wetlands of the planet for the remaining escape pods. Unbeknownst to them, two commando droids were watching them from afar, and utilizing a sniper rifle, shot at Rex, knocking his off his speeder. Being their medic, Kix immediately swerved backwards to protect the unconscious captain, while Jesse and Hardcase followed the snipers. While Jesse and Hardcase destroyed the commando droids, Kix examined his injuries, discovering that Rex was still alive, but it was severe and he had been shot two inches from his heart. Deciding there was no way to continue their mission in the state they were in, they concluded that they would need to find some cover for the time being. Noting a domesticated eopie standing behind them, he established that they were on farmland, so the group set off to find the farmer's homestead.

Upon discovering a nearby homestead, they were greeted anxiously by a female Twi'lek, Suu Lawquane, who pointed her rifle at them. Kix and Jesse explained to her that they were not there to bring harm, and instead simply needed a place for their injured captain to stay for the night. Suu gave them permission to stay and allowed them to do so in the barn. Once inside, Kix patched up Rex's wound with a bacta bandage, allowing him to regain consciousness shortly after. As he awoke, Jesse and Hardcase informed him what had ensued. Much to Rex's dismay, Kix told him he was in no condition to fight and continue their mission, and that he must have some rest. Not wanting to put the mission in jeopardy, Rex gave the responsibility of leading the group to Jesse. Kenobi then contacted the group via comlink, with Jesse responding and letting him know that Rex had been injured, and the group was now his responsibility. Kenobi informed him that Grievous was heading for an abandoned but still working escape pod, and ordered them to drive westward, so they could trap the general between the two squads.

Sometime later, Jesse contacted Kenobi, telling him that he had a clear visual of the escape pod, and that Grievous had already arrived. Kenobi and his team had already engaged Grievous' forces on their own by the time Kix and his group had gotten there. As they shot at the battle droids on their speeders, Jesse noticed a Separatist shuttle arriving on the planet, and warned Kenobi via comlink. As it came closer, the All Terrain Tactical Enforcer's guns overheated, so Kenobi rushed to engage Grievous one on one. They dueled briefly, before the shuttle came low enough to the ground for Grievous to fire a tow cable at it, escaping with the ship. While Kix remained with Hardcase on the speeders, Jesse and Cody returned to Kenobi's company, where he instructed them to contact the fleet to bring a shuttle to pick them up.

Sometime later in the war, Kix accompanied the 501st legion, led by Jedi Knight Anakin Skywalker and CT-7567 "Rex," on a full-scale attack on the planet of Umbara to fight off the Umbaran Militia and retake the planet from the Separatists. As gunships transported troops down to the ground, the battle began, with Kix and the rest of the 501st fighting off and intercepting Umbaran forces north of the capital city. The enemy forces proved relentless in their efforts, and the 501st took heavy casualties despite gaining ground. Eventually, the clone pilot Davijaan "Odd Ball," along with his team of Y-wing bombers, dropped munitions over a ridge, eliminating all Umbarans in the area and pausing the battle. During this time, General Pong Krell arrived, who had also been involved with the assault. Upon landing, he informed Skywalker that he had been ordered back to Coruscant without delay, adding that he, Krell, would resume command of the 501st for the remainder of the Umbaran campaign. Reluctantly, Skywalker boarded a Republic gunship, as Rex greeted the new general.

Kix, along with the 501st, immediately moved out under strict protocol from the Besalisk Jedi Master. The men trekked across the rough Umbaran terrain for 12 hours straight, which led Kix to worry for his brothers' increasing fatigue. Kix voiced his concerns to Rex, who suggested that the group make camp on a nearby ridge. The suggestion mortified Krell, who announced to the clones that rest was a luxury the Republic did not have, and that they would continue walking. The clones eventually made it to the capital, where Krell immediately briefed them with new orders. The clones were to scrap Skywalker's initial plan to surprise attack the Umbarans, and were to instead launch a full-frontal assault—one that would endure high casualties. Rex did not agree with this plan; however, they followed the order. As Kix and the other members of the 501st reached the main road, the Umbarans surprise-attacked them, forcing them to fall back.

In order to combat the Umbaran forces, the clones entered the jungle, where they still received heavy blaster fire from the enemy, causing many casualties. Kix saved as many of the injured as he could, calling for cover from Rex, Dogma, and Jesse as he administered temporary stimulants to the fallen troopers. In the midst of the battle, Krell received word from General Kenobi that he was unable to capture the capital, and would require the 501st to capture an Umbaran Airbase. Krell obliged, and after the Umbaran forces were fought off, they set off for the airbase. Many of the troops—including Kix, Jesse, CT-5385 "Tup," and CT-5555 "Fives"—objected to Krell's tactics, and though Rex attempted to defend them, the clones were still not at ease. Rex then split the 501st into two separate groups. Rex was to lead his division along the outskirts of the canyon while Fives took his division—which included Kix—through the other side of the gorge. Fives' division was the first to meet Umbaran resistance, in the form of an Impeding Assault Tank. Kix tended to the wounded, as the rest dealt with the tank before continuing on together.

As they continued walking, Kix spotted several banshees picking at their fallen comrades. Clearly angered by this, he immediately sprang towards them, shooting and killing the flying vermin. Rex then ordered Kix to leave them and to continue walking. As the troops closed in on the airbase, the Umbarans deployed an Umbaran mobile heavy cannon to deal with the clones. It ripped through the clones with ease, causing many casualties. Rex contacted Krell about the impending threat, requesting immediate backup; this was denied. Krell ordered the clones to press on with the attack. Obeying, Rex mobilized the remaining men, and directed Kix to keep the wounded as quiet as possible. As expected, their weapons were little match for the heavy cannon, and the 501st quickly sustained egregious losses. In the turmoil, Kix requested help in getting the wounded to safety, to which Rex quickly came to assist. Just as Kix went to rescue more of the injured, Rex told the clone medic he would have to leave them behind. Kix strongly disagreed with his sentiment, stating that they couldn't simply leave the men behind, to which Rex told him that it was more important to save himself in the given situation, and if they survived, he would be able to patch up the wounded later. Kix remarked that Rex sounded just like General Krell. Seeing no other way out, Rex ordered Fives and Hardcase to go behind enemy lines to steal two of the enemy's starfighters to provide some air support. The two succeeded with their mission, and destroyed the heavy cannons using the starfighters and captured the airbase.

Despite the capture of the airbase, the Umbarans were still able to receive supplies and arms shipments, due to a supply ship that was orbiting the planet. Regardless of this fact, General Krell decided against destroying the ship, and instead ordered the clones to continue closing in on the capital. Many of the clones once again disagreed with Krell's strategy, most notably Fives, who suggested they should use the stolen Umbaran starfighters to destroy the supply ship. Rex then proposed the new plan to Krell, who felt it was a waste of time, stating that the attack on the capital would still be commencing. Outraged by this, Fives took matters into his own hands, defying the general by gathering Hardcase and Jesse to help him with his mission. Kix supported this, and helped prepare the starfighters for the impending attack on the supply ship. Fives, Jesse and Hardcase proceeded with their plan, without the knowledge on General Krell. Their mission succeeded: they snuck behind enemy lines, with Hardcase sacrificing himself to manually destroy the ship. They were not given a heroes' welcome back to Umbara, however, as Fives and Jesse were court-martialed for defying a direct order from the general.

Rex attempted to change the irrational Jedi's mind about court-martialing Jesse and Fives, but this only made things worse. Krell ordered the execution of the two clones for their insubordination, calling for a firing squad immediately. Kix was among the men in the firing squad, who—upon being ordered to execute their brothers—refused, instead purposely missing and hitting the wall behind them. Dogma was shocked by this, telling the clones that they must follow through with their orders. Rex sarcastically wished him good luck in trying to find someone else willing to do it. Krell then called for both Rex and Dogma to report to him why they had failed to carry out the execution. As Rex and Krell bickered, they received a transmission from a clone, who claimed that the Umbarans had attacked them, stealing their weapons and armor. Krell then decided it was best for the clones to launch an attack now while they still could, reminding Rex to tell the troops that the Umbarans would be wearing clone armor. The 501st immediately moved to engage in battle; they were promptly sprayed down with enemy fire. Kix, using his night-vision filters, saw that the opposing soldiers were wearing 212th armor and concluded that they were disguised Umbarans, just as Krell had cautioned. The battle commenced for a short while before Rex realized that the enemies were not in fact Umbarans in disguise, but were actually their own brothers in the 212th Legion.

Rex frantically ran across the battlefield with his helmet removed, screaming that they were all clones and to cease fire. Upon this realization, members of both the 501st and the 212th Legions were shocked, all of them removing their helmets and looking at each other in disbelief. Kix was quick to locate the platoon leader, Waxer, who had been mortally wounded. He called Rex over to discover how the two clone legions ended up attacking each other. Kix tended to his injuries, as the shell-shocked Waxer informed them of how his men were notified that the enemy were wearing their armor and were ordered to attack by General Krell. A tear shed from Waxer's eye as he died from his injuries. Rex gathered a group of men, including Kix and Tup, and suggested that they arrest Krell for treason against the Republic. Back at the airbase, Kix, Tup, and Rex freed Fives and Jesse from their cell and gathered more men to storm the command center. The clones confronted Krell about his recent actions, to which he activated his double-bladed lightsabers and instantly sliced through many clones. He then fled the command center, smashing and leaping out of the windows.

Krell escaped into the Umbaran jungle, with the clones closely pursuing him. They eventually caught up, and Krell attacked, causing even more casualties. As Kix and the other clones fired on him, Tup came up with a plan. The clones lured the rogue Jedi towards him, and Tup baited the general into the tentacles of a ravenous vixus, which swiftly grabbed him and tossed him around. Tup then shot the vixus, killing it, causing Krell to be hurled to the ground, where the clone stunned him. Krell was taken to the same prison block that he had imprisoned Jesse and Fives in not too long before. There, he revealed he had been plotting with the Separatists since the beginning, taunting them that they had all been foolish. The clones soon received word that an attack from the Umbarans was inevitable, so Rex made the uneasy decision that it was best to execute Krell so that he could not escape via the Umbaran attack. Rex, Jesse, Fives, Tup, and Dogma then re-entered the prison block, where Rex prepared to execute the rogue Jedi. Krell tormented Rex, knowing that he would not be able to execute a Jedi Master; however, the Besalisk traitor was suddenly shot by his most loyal trooper, Dogma. Following this, Kenobi's forces took the capital, and the Umbaran threat was diminished.

Shortly after the Umbaran campaign, Kix and the rest of the 501st legion were sent to Kiros, after governor Gupat Roshti, the leader of a colony of Togrutas residing on the planet, decided to negotiate with Count Dooku over the welfare of his people. Upon arriving on the planet, Kix and the rest of the 501st, led by Obi-Wan Kenobi, Anakin Skywalker and Ahsoka Tano, mounted BARC speeders as they trekked across the colony. They soon realized that the colony was extremely quiet, noting that nobody had seen a single colonist at all, leaving Rex to theorize that the Separatists could potentially be using them as living shields. As they made for the city center, they encountered a group of commando droids, who led them into an Armored Assault Tank along with several other B1-series battle droids. After a small skirmish, they defeated them, with Kenobi then ordering the city center and the governors' tower to be secured. Kenobi then received a transmission from a Zygerrian known as Darts D'Nar, who was residing inside of the governors' tower, asking to meet him inside to discuss his surrender.

Upon entering the tower, Kenobi immediately saw D'Nar speaking with Count Dooku and fellow Zygerrian Atai Molec, over hologram. Dooku ordered D'Nar to bring Kenobi to him on his knees, telling him he would be forced to surrender. D'Nar then explained to him that he had planted bombs all across the city, and should he not surrender he would set them off. Kenobi said that if he were to surrender, the Zygerrian would first have to release the colonists that the Separatists had clearly kidnapped, to which D'Nar responded with a counteroffer, as he set off one of the bombs. The explosion had been set off next to the Republic forces back on the ground, injuring many clones. Skywalker called for a medic to treat a particularly wounded clone, to whom Kix immediately ran over to help. While Kix treated the many injured men, Skywalker and Tano set off to disarm the other bombs, and Kenobi continued to negotiate with D'Nar.

In the latter part of the war, Kix participated in the Battle of Ringo Vinda, a military campaign in which the 501st, led by Skywalker, were sent to defeat Separatist forces on a space station surrounding the planet of Ringo Vinda. In the midst of battle, clone trooper Tup fired upon and killed Jedi General Tiplar under mysterious circumstances, forcing the Republic forces to retreat. Upon securing a safe location, they attempted to determine why Tup had mercilessly murdered a commander in cold blood. Taking the volatile clone to the side, Rex noted that he had believed Tup had simply snapped, as he began spontaneously repeating that "good soldiers follow orders." As the medic, Kix, assessed Tup and waved his hand in front of the clone's face. Tup suddenly lashed out, forcing Tiplar's sister, Tiplee, to suspend him using the Force.

Following this, Tup was left to rest in a medical bay. Sometime later, Kix, Fives, Rex, Tiplee, and Skywalker returned to check up on his condition. Tup was once again conscious, and was completely unaware of his actions, and upon being informed by Fives of what he had done, he broke down, denying that it could be possible. As a result of his brash reaction, the medical droid was forced to sedate him. Skywalker then asked Kix if he had checked all of Tup's medical scans, to which he replied that from his knowledge, it appeared to be a combat-related stress and that he had broken down. Rex and Fives were not convinced however, noting that they as clones were engineered to withstand it. They then quizzed that it could have been the work of biological warfare, and that the enemy had drugged him into killing the Jedi. Kix then came to the conclusion that the only way they could be certain what had happened was to send Tup to Kamino, in order to be fully examined.

Following the events of the Ringo Vinda campaign, the 501st Legion returned to Coruscant. On one of the nights following their arrival, Kix and Jesse were socializing at the clone bar, 79's. Fives had been framed for attempting to murder Supreme Chancellor Palpatine, after discovering the truth behind the reasoning that Tup had executed Jedi Master Tiplar, and while on the run from Republic forces, sought refuge in the bar. Upon entering, he spotted Kix, and followed him into the bathroom. While the clone medic was looking at himself in the mirror, Fives conversed with him, noting that the 501st was now back on Coruscant. Kix then remarked that a strange occurrence had happened while on Ringo Vinda, whereupon Fives revealed himself to him, stating that he knew.

Kix was bewildered to see Fives, and told him that rumors had circulated of how he attempted to murder the Chancellor, and that he had been infected with the same virus that Tup had supposedly been infected with. Fives then vaguely told Kix that the clones and the Jedi had all been framed, and were all in grave danger. He pleaded that he needed to make contact with Rex or Skywalker immediately, to which Kix gave the advice that Fives should turn himself in. Fives exclaimed that Kix simply didn't understand, and that he had been involved in a conspiracy that reached the highest levels of the Republic. Fives then gave Kix coordinates to send to Rex, and asked for him to tell the captain to meet him there. Kix agreed, and promised to pass them on. The two parted ways, with Kix wishing him luck with whatever Fives was planning to do.

The information Fives had given Kix had a profound effect on the clone medic, leaving him with many questions he sought answers for.

Kix later participated in the Battle of Anaxes, a lengthy campaign between the Galactic Republic and the Confederacy of Independent Systems over the planet of Anaxes. During the campaign, the Republic forces were initially losing repeatedly, and the Separatists emerged on the verge of victory. Suspicious, Rex and Cody met with Jedi Generals Skywalker and Mace Windu. Rex theorized that the Separatists had learned his personal combat strategy, and, based on the tactics used by himself and the Separatists, secretly thought that CT-1409 "Echo," an ARC trooper thought to have been killed during the Battle of Lola Sayu, was still alive. To learn what was happening, Cody requested he and Rex bring a squad behind Separatist lines to the Cyber Center.

Windu approved Cody's plan of bringing a squad, and the force included Kix and Jesse. For the mission, Cody called for the help of Clone Force 99, nicknamed, "The Bad Batch," an elite group of clones with desirable genetic mutations. Rex and Cody then gathered Kix and Jesse to walk with them, and greet the mutated clones for themselves. As they arrived, the Bad Batch flew their shuttle aggressively into the hangar, leading Kix and Jesse to exchange looks of contempt. Kix exclaimed and questioned how exactly they were clones, due to their different appearance, to which Cody explained their genetic modifications. Cody subsequently introduced everybody, and the group stepped into the Republic Gunship to be taken behind enemy lines.

As they approached the base, the gunship was spotted by a group of B1 battle droids, who contacted a DSD1 dwarf spider droid, ordering it to shoot the ship down. After a few shots, it eventually made a direct hit on the gunship causing it to crash into the surface of the planet. Upon climbing out, Kix noticed that Cody had been left trapped underneath part of the rubble from the gunship and called for help. Bad Batch member, Wrecker volunteered to rescue him alone, much to Kix's discontent who believed that he would need help in doing so. The Batch's sniper, Crosshair, was amused by Kix's complaints and explained that Wrecker was going to move the gunship, not Cody. Wrecker lifted the gunship with ease, picking up Cody's injured body, as the ship burst into flames behind him. Kix then assessed his injuries, finding that he had internal damage, and would be able to reduce the pain if he found help fast. As Kix got his medikit out, a large group of battle droids began heading their way. Kix, Jesse, and Rex stayed to tend to Cody while members of the Bad Batch, Hunter, Crosshair, Tech, and Wrecker fought off the droids.

Later in the evening, after moving away from the crash site, the group set up camp for the night. As they ate, Kix and Jesse discussed what Hunter's genetic modification could be, before Tech interrupted them, informing them of Hunter's heightened tracking skills. Due the agony he was in, Rex called in an extraction unit to pick up Cody and take him to be better treated for his injuries. Informing the Bad Batch of the situation, and where to go forward, Crosshair disagreed, and then interrupted and questioned Rex's leadership skills if they were forced to bring in The Bad Batch to aid them. Instantly springing to Rex's defense, Jesse demanded to know who he thought he was talking to, before Wrecker grabbed him by the throat. Attempting to help his friend, Kix became involved, before he and Crosshair engaged in a fight. Before the situation got out of hand, both Rex and Hunter calmed their men—reminding them they were both on the same side, and fighting for the same thing. The others then prepared to move out and continue the assault, while Kix remained with Cody to carry on with treating his injuries before the extraction unit arrived.

Sometime after the Battle of Anaxes, Kix began questioning the so-called virus that had caused fellow clone trooper Tup to kill General Tiplar. He conducted his own further investigations into the matter after he discovered that Fives had discovered the truth before his untimely death. Kix eventually discovered the truth for himself, learning that the biochip implanted in every clone soldier's head could send out an order directly from the Chancellor to betray and kill the Jedi. His investigations did not go unnoticed, however, as Count Dooku, the public leader of the Confederacy of Independent Systems and apprentice to Darth Sidious, ordered his kidnapping before he could share his knowledge with the Jedi. Kix was captured and interrogated to find out if anybody else in the Republic knew of the information. Believing the trooper to be deceiving them, the Separatists planned to send him to the Sith themselves, and in turn, brought him on board a Separatist cruiser known as the Obrexta III. On the ship, he was frozen and inserted into a cryo-cycle stasis pod, where he would remain until the ship arrived on Serenno. As the cruiser took off, it was ambushed by Republic forces. With little chance to raise the shields, the Republic fleet made easy work of the cruiser, resulting in heavy damage. A B1 battle droid known as B1-CC14 concluded that the ship was in no shape to go to Serenno, as well as being on strict orders for Kix to not fall into the hands of the Republic at any costs. With no other options in sight, the droid jumped through hyperspace to a random sector in the galaxy, where the Republic would have no chance of finding it.

The jump transported the ship, along with its cargo, Kix, to the desert planet Ponemah Terminal, where it inevitably crashed on the surface. The ship, along with B1-CC14 and the other droids on it, lost their power as a result of the crash, where they would remain lifeless for many years to come. Although Count Dooku never actually dealt with Kix, Kix was never able to tell the Jedi the truth of the biochips in the clone troopers, and Order 66 was carried out, with the subsequent extermination of the Jedi. Kix lay in stasis, and the ship remained untouched for the next 50 years.

Exactly fifty standard years after the end of the Clone Wars, the Delphidian pirate Sidon Ithano and his crew of the Meson Martinet resided in a cantina on the desert world of Ponemah, the very planet that the Obrexata III crash-landed on many years prior. There, the crew of pirates managed to decode an old transmission dating back to the Clone Wars from B1-CC14, who was desperately attempting to send out a distress signal. In his message, he mentioned very important cargo belonging to Count Dooku himself. Instantly recognizing that the signal must have come from the crashed Separatist ship on Ponemah, Sidon Ithano and the crew of the Meson Martinet set off to claim the treasure for themselves. It was not only Sidon Ithano's crew that knew of Count Dooku's treasure, however, as various other pirate groups, gangs, and raiders operating on the planet also decoded the transmission. The race was on to get there first, with none of them actually knowing that the so-called treasure was, in fact, the clone trooper Kix—still frozen in stasis and alive all these years later.

En route to the downed Separatist ship, the various groups clashed, with a huge battle taking place at one point between Sidon Ithano's crew and a swoop biker gang known as the Gray Gundarks. Ithano and his crew narrowly won the skirmish and were the first to arrive at the ship. They raced through the corridors of the ship with ease as they came up to the ship's vault. The group were shocked upon finding no treasure, and instead a cryo-cycle stasis pod. With nothing left to lose, they decided to awaken the pod, and even more shockingly, Kix emerged. He seemed startled and shell-shocked, finding it hard to breathe properly and gasping for air. He immediately began rambling and muttering—attempting to inform the pirates what had happened. He explained to them that he had learned a terrible truth about his fellow clone troopers, that the biochip implanted in their heads—supposedly to stop them from being controlled—was actually in place to command and force the clones into complying to betray and kill their Jedi generals. He described how the Separatists found out that he knew and kidnapped him, subsequently torturing him and later putting him into the very stasis pod he had been found in. Not knowing how long he had been frozen for, Kix requested that the pirates transport him to the Republic so he could inform General Anakin Skywalker and save the Jedi from their inevitable fate; he then slipped into unconsciousness.

As this was happening, B1-CC14 briefly re-awoke after a sudden surge of energy sparked its power receptors. The droid immediately realized with his only remaining good sensor that the vault where Kix was being stored had been broken into. Upon remembering his last orders—Kix must not escape, no matter the cost—B1-CC14 triggered the emergency activation systems with his last ebb of energy, which caused a contingent of super battle droids to be signaled to the intruders' location. The ship subsequently began falling apart, with the Crimson Corsair ordering that he and his crew leave immediately, taking the unconscious Kix with them. The droids shot and killed the Ishi-Tib pirate, Pendewqell, while the rest of the crew headed towards the escape pods while still carrying Kix. But there was only one escape pod, and not enough room for the entire crew. Sidon Ithano bravely shoved his fellow pirates, as well as the still-unconscious Kix, into the escape pod, then launched the pod into the sand while he stayed behind in the doomed cruiser.

Over three weeks after the crew of the Meson Martinet retrieved Kix from the Separatist ship instead of the riches and treasures they had desired, they remained on Ponemah, waiting for their captain to return. Kix was still in deep shock over the many revelations of galactic history he had learned since awakening, being particularly saddened that he was never able to save the Jedi and the Republic from their fate. Just as they planned to leave the desert world, Ithano suddenly appeared, alive and well. He waved away questions, and handed the Separatist cruiser's memory core to Kix, which contained a complete map to every hidden factory ever built by the Separatists. Kix agreed to join the Crimson Corsair's crew to scour the galaxy with them, discovering new treasures together.

Upon joining the crew of the Meson Martinet, Kix stopped shaving his head and grew out thick black hair, in addition to a beard, and this covered the tattoo on the side of his scalp. He outfitted himself with Phase I clone trooper armor that was blue in color with several red stripes. At some point, Kix, Sidon Ithano, and a red Twi'lek known as Reveth were situated in a misty swamp, where they were ambushed by B1 battle droids, which were unearthing themselves from the ground, trying to reach the crew. C-3PO later referenced this story to some visitors by referring to it as "spooky."

When a group of slavers led by Gruk captured Ithano's first mate Quiggold, he regaled details about the Crimson Corsair's crew, describing Kix as a vengeful clone who could not stop fighting in a war that had already ended. Several of the slavers became nervous when hearing of this, and as Quiggold finished, Kix came aboard, killing several of Quiggold's captors. Along with Ithano and Reveth, Kix took control of the bridge and freed Quiggold. Taking his helmet off, he remained silent and sat alone as Ithano detailed their next plans.

In 31 ABY, a group of scoundrels frequenting Takodana Castle discussed the rumors of the long-lost clone trooper. A Devaronian loudly expressed that they did not believe there existed such a clone who had the location of old Separatist treasures.

As a trained clone trooper medic, Kix believed that when it came to the health of his comrades, he outranked them. Instead of worrying about his enemies, Kix cared more about the welfare and livelihood of his fellow troopers, armed with medpacs and pain stims to help out in any way he could. During the Battle of Saleucami, Kix respected Rex when the clone told him of how he had been injured after being shot by a commando droid's sniper rifle. He took great concern for Rex's health, and advised Jesse and Hardcase that in order to see the full extent of Rex's injury, he had to remove pieces of Rex's armor. After Rex handed the leading position to Jesse, Kix cooperated with Jesse's orders that were given to himself and Hardcase. He held a high sense of honor to his fallen brothers, as shown by him getting angered by and attacking a group of banshees which were feeding off of troopers' corpses. As a field medic, Kix was equipped with medpacs, as well as other first-aid commodities, to help fellow injured clone troopers during a battle. Kix also carried a blaster rifle.

Kix kept his head completely shaved. On the left side of his head on his scalp, Kix had a tattoo that said "a good droid is a dead one" in Aurebesh as well as other tattoos depicting a design of lightning bolts. By the Battle of Anaxes, Kix had grown a full head of hair, largely covering this tattoo. After being revived by Sidon Ithano, Kix grew a beard but later shaved it. He fought as if the Clone Wars never ended for him, with his fellow pirates noting his long dead brothers seemed to whisper to him as he dealt with the trauma of being the last of his kind. Quiggold describes him by saying "He's so angry. And he's so sad."

After his time in Phase I clone trooper armor, Kix wore Phase II clone trooper armor throughout the rest of the Clone Wars with blue markings like others in the 501st Legion. Since he was a medic, Kix sported a red medic symbol of the Republic Medic Corps on his left shoulder and carried a backpack of medical supplies into battle with him. Kix also could use a DC-15A blaster carbine during the Clone Wars. After reawakening, he wore a suit of dark phase one armor and wielded two DC-17 hand blasters.

Kix was first featured in the tenth episode of the second season of Star Wars: The Clone Wars, "The Deserter." Like every clone on the show, he was voiced by Dee Bradley Baker. Kix was later incorporated in the short story "The Crimson Corsair and the Lost Treasure of Count Dooku," written by Landry Q. Walker, which was set around the same time period as . He also made a cameo, as his later self, in the short comic Star Wars Adventures Ashcan, also written by Walker. Artist Eric Jones made concept art of him for the comic appearance.

According to Walker, Kix stopped shaving because of the sorrow he felt every time he looked in the mirror as he was reminded of his fallen comrade brothers who he was unable to save. Walker also said he would likely wear a helmet as well. Kix was not referred to by name in the Star Wars Adventures Ashcan, but concept art confirmed it to be him.
