X1

"As his brother, it was my sworn duty to stop him."

- X2, prior to the Battle of Mustafar

X1 was a Force-sensitive clone trooper created by the Galactic Republic who would go on to serve the Empire and the Sith. Along with his brother, X2, he was created from the DNA of a Jedi Knight, Falon Grey, and grew up in secret on Kamino with the purpose of training the Clone Army. Following the outbreak of the Clone Wars in 22 BBY, X1 and his brother fought in many battles and helped train young clone troopers under the eye of Master Ferroda. Following their exploits during the Battle of Tatooine, the two gained special recognition from Supreme Chancellor Palpatine, and played important roles during the Battle of Coruscant. During the battle on Cato Neimoidia, Order 66 was enacted, X1 and his brother were forced to kill Ferroda.

As the new Galactic Empire rose in power, X1 and his brother served in its military ranks. However, following a mission to Dantooine to kill a fugitive Jedi, X1 and his brother took separate paths. X2 defected from the Empire; as a result, X1 vowed to hunt him down and killed the Jedi on the planet, none other than his genetic "father", Falon Grey, and knocked X2 unconscious, believing him to be dead. X1 continued to serve the Imperial Military for almost two decades, playing a minor role in the construction of the Death Star and also gained some mastery with the dark side. At the Battle of Hoth, a decisive Imperial victory, X1 commanded the Star Destroyer Avarice. Inside the ship, he saw his brother for the first time in over fifteen years and inconclusively dueled him. After the Battle of Endor and the death of the Emperor, X1 became one of many Imperial warlords fighting for control of the shattered empire. He also proclaimed himslef to be a Sith Lord and operated from a temporary base on Dathomir and then from Darth Vader's fortress on Vjun. X2, now a Jedi Knight, infiltrated the fortress only to find that X1 had escaped. X1 fled to Mustafar, where he planned to conquer the galaxy by using an army of clones following Luke Skywalker's capture. However, using a Sith holocron, X2 tracked him there and attacked the planet in a climactic battle. X1 dueled his brother multiple times, first aboard his Star Destroyer and then on the fiery surface. Finally, as the New Republic forces destroyed X1's base of operations, X1 confronted his brother one last time, and X2 defeated him, ending the threat he posed to the galaxy.

Creation
"The Kamino cloners must have taken my genetic information without my consent. With it, they made you my son...and your brother X1."

- Falon Grey

X1, along with his brother, X2, was a Force-sensitive clone trooper created by the Kaminoans using the DNA of the Jedi Knight Falon Grey. Prior to 22 BBY, Grey was badly injured while traveling with his master, Rahm Kota, and Kota made an emergency landing on the planet of Kamino, where the Kaminoans healed Grey, but in exchange took a sample of Grey's genetics without his consent. From the sample, they produced two clones, X1 and X2. The two grew up unaware of their origins, raised in secret by the Kaminoans alongside other clones created on the request of Jedi Master Sifo-Dyas and cloned from the bounty hunter Jango Fett's genes. During this time, X1 and X2 were responsible for training their clone brothers.

Fighting on Tatooine
"Now that's what I call a victory, little brother! There'll be medals in this for both of us!"

- X1, to X2

In 22 BBY, the Clone Wars began with the Battle of Geonosis. X1 and X2 became clone troopers in the Grand Army of the Republic and fought together many times during the conflict. Due to their exceptional abilities, they were assigned to train young clone troopers to be better soldiers. In 19 BBY,, during the latest stages of the war, X1 and X2 went to Tatooine in order to oversee the training of new clone troopers in a training outpost in Mos Eisley. After telling X2 to demonstrate various fighting skills to the clones, X1 helped in the training session. However, the training session was abruptly stopped after the discovery of a CIS recon droid inside the Republic hangar. X1 ordered his brother to destroy the droids, as well as the others in the reconnaisance patrol. He then sent X2 in a V-wing into space in order to destroy the transport ship from which the droids had been deployed.

However, the brothers' troubles were far from over. X1 realized that an invasion of Tatooine was underway, so he X2 prepared for the ensuing battle. X1 and X2 began in the Republic hangar, giving support to clone pilots who were trapped inside. The Separatists continued their attack, sending spider walkers into Mose Eisley. Lacking the heavy weapons necessary to destroy the spider droids, X1 and his brother went through a cantina and destroyed the battle droids inside. X1 then sent reinforcements onto the battlefield as X2 destroyed the droids. X1 sent X2 to fire the ion cannon in order to destroy the shields of a Separatist battleship flying above Tatooine. With the hangar clear and the CIS cruiser's shields down, X1 and his brother took V-wing starfighters into space and fought the droid starfighters flying around the ship. X1 sent X2 into the ship's interior in order to sabotage the reactor core and therefore destroy the cruiser, which X2 succeeded in doing. In the end, the Battle of Tatooine was a Republic victory.

End of the war
"Ah, I understand&hellip;Identical, but separated only by a few hours&hellip;perhaps separated by something more."

- Palpatine, upon first meeting X1 and X2

Following their exploits at the Battle of Tatooine, Supreme Chancellor Palpatine invited X1 and X2 to Coruscant the Republic's capital, for a special ceremony. Palpatine confused X1 with X2 before X1 explained the msiunderstanding. However, the ceremony was abruptly stopped after the Confederacy attacked the world. After ordering a group of clone troopers to get the Chancellor to safety, X1 and X2 separated taking separate routes through Coruscant's streets. After X2 injured General Grievousin combat, X1 went with his brother into space, taking nearby ARC-170 starfighters and battling Separatist Vulture droids. Soon, they were joined by Jedi Knights Anakin Skywalker and Obi-Wan Kenobi, who had arrived to rescue the Chancellor. X1 continued flying in the space battle as X2 flew into a nearby destroyer's hangar in order to sabotage it. The brothers' actions helped the Republic rescue Palpatine and win the Battle of Coruscant.

The Clone Wars were almost over, but the Republic was still fighting on many important worlds. X1 and X2 battled alongside Ferroda on Cato Neimoidia at the end of the war. X1 led clone troopers in the bridge cities in order to capture the planet. X2, having fought in space over the planet, joined him in the ground battle. As the troopers advanced on Viceroy Gunray's palace, X1 sent his brother to deactivate the battle droids from inside the palace. Soon, the droids were no longer a threat to the clones.

However, a message from Coruscant would completely change the outcome of the battle. Palpatine told the clone troopers that Ferroda, and all other Jedi, had betrayed the Republic and ordered them to execute Order 66 and kill Ferroda. X1 forced his brother to comply, and the two of them, along with the other clone troopers, attacked the Jedi Master. However, Ferroda would not fall so easily. He wounded X1 and killed most of the clones in the platoon, leaving only X2. Finally, he obeyed the order and killed Ferroda, a decision that would shape the destiny of both brothers.

Service to the Empire
"The rise of the Galactic Empire offered X1 power beyond his wildest dreams. But Order 66 and the Jedi Purge soon turned brother against brother."

- X2

Taking separate paths
Soon after Order 66 was issued, the Republic was reformed into the Galactic Empire with Palpatine as its Emperor. X1 and X2 became stormtroopers and began their service in the Empire, eventually earning a reputation as two of the Empire's most trusted agents. However, ever since Order 66, X2 felt that he was not doing the right thing and began to show sufficient signs of concern that X1 noticed. At some point between 17 BBY and 15 BBY, the brothers&mdash;under the supervision of the Dark Lord of the Sith Darth Vader, formerly Anakin Skywalker&mdash;were assigned to hunt down a fugitive Jedi, who was hiding among villagers on the planet Dantooine. Vader believed that the clones would help him to exterminate the remains of the Jedi Order. When X2 hesitated to embark on the mission, X1 told him to follow orders.

X2 complied, and the brothers, along with other troopers, took ARC-170s and headed for the planetary surface. X1 issued an order to enter the atmosphere and destroy the village where the Jedi was hiding. X2, not wanting to kill innocent people, protested to this course of action, believing that they had come for the Jedi only. X1, however, was certain that the villagers deserved to die for harboring a Jedi. X2 continued to argue, and X1 ordered Zeta Squadron to escort him back to the carrier ship. X2, angered by X1's commands, decided that he could not follow him anymore. He said goodbye to his brother, intending to defect. X1 immediately branded him a traitor and ordered X2's squadmates to kill him.

Once X2 opened the hangar's door, however, X1 and his stormtroopers landed in LAATs. They killed all of the remaining members of the militia and wounded X2 with a blaster bolt, but Grey used the Force to blast off the stormtroopers and attacked X1, who was armed with a force pike. The two dueled, and Grey emerged victorious. Sensing that there was still some good in X1 and wishing to draw him from the path of darkness he had taken, Falon Grey spared him and even returned his force pike to him. X1, however, attacked the Jedi again and took hold of his lightsaber. He then shot Grey with his blaster and cut X2 with Grey's lightsaber, leaving his brother to die as he and the stormtroopers departed the planet. Before dying, Grey was able to reach out with the Force and heal X2's wounds. X2 survived and spent the following fifteen years working as a simple farmer on Dantooine. At some point between 2 BBY and 0 BBY, the Alliance to Restore the Republic sent Jedi Master Rahm Kota to recruit Falon Grey to their cause, whom they still thought to be alive. Kota, who held no respect for clones, was disappointed to find only a "pale imitation" of his former Padawan. Still, he sensed the Force resonating in X2 and made him an offer to join the Rebellion, which X2 accepted.

The early Galactic Civil War
"Whatever happened to your brother? Does he still serve the Empire, I wonder?"

- Rahm Kota

X1 rose in the ranks of the Imperial Army, unaware that his brother had joined the Alliance to Restore the Republic created by Galen Marek. He played a small role in the operation of the Death Star. When the Rebel Alliance managed to destroy Desolation Station along with the Tributary Superlaser component for the Death Star, he personally executed the station's commander. X1 was also involved in the Battle of Hoth. He commanded the Star Destroyer Avarice. X2 had boarded the Avarice in an attempt to destroy the Star Destroyer to aid in the Rebel evacuation of Hoth, but X1 ambushed and attacked him, who brandished Falon Grey's lightsaber, and seemed to have gained some measure of proficiency with the dark side. X2 defeated X1, and X1 fled. He was later involved in the Battle of Bespin but failed to hold the planet. He disappeared and studied many dark side secrets.

Sith Lord
"Vader and Palpatine were slain&hellip;and the Death Star obliterated. For a brief moment we celebrated. But X1 was already drawing up plans for a new Galactic Empire, with himself at the throne."

- X2

Fighting for power


After the destruction of the second Death Star and the establishment of the New Republic, X1 became a Sith Lord and tattooed his head after shaving it. X2 vowed to track down X1 and bring him to justice. X1 operated from Darth Vader's fortress on the acid planet of Vjun, Bast Castle, and created a Sith holocron for himself. X2 and Grey Squadron visited the planet to capture X1, but as X2 discovered on the holocron, the Sith Lord had already fled to Mustafar.

Showdown on Mustafar
"After him, X2! If we want to restore peace to the galaxy, we have to stop X1 now!"

- Shara

X1 had built an army of insane clones on Mustafar and planned to use Luke Skywalker as a genetic template. X1 used a cloning facility to attempt to use Luke to create thousands of Dark Jedi. X2 and New Republic soldiers tracked X1 to the fiery world and fought the stormtroopers found X1 waiting for him. X1 had become infused with the power of the dark side, and was physically distorted in a similar manner to Palpatine's disfigurement. X2 managed to overpower X1, but in a final act, X1 tried to use his dropped lightsaber to impale X2. X2 jumped over the lightsaber, causing X1 to be impaled by his own blade. X1 fell into the lava rivers and died painfully. His death marked the end to his army.

Personality and traits
"You should realize you destroy your enemies when you make peace with them.''" "''You should realize you can only make peace after destroying your enemies completely."

- Falon Grey and X1 on Dantooine
