X-6

X-6 was a Human male assassin who, along with six other men, was hired to participate in Project Omega. The project was an experiment by Commander Rezi Soresh to create the perfect assassin, who would then go on to serve the Galactic Empire. After Soresh wiped the participants' identities from a computer database system and had their faces surgically altered, he started his brutal reconditioning program, which was designed to turn them into mindless servants by removing their past memories and emotions.

At first, X-6 became friends with X-1, X-2, X-3, X-4, X-5 and X-7, the other participants in the training program. Nevertheless, after Soresh started torturing them with electrocution, X-6, like his fellows, had their personality and mind changed completely until they felt no emotions. Around 10 BBY, the assassins-in-training were all pitted against each other until only one remained. X-7 easily killed X-6 and earned the right to become Soresh's personal assassin.
