In the Game, Immortal Konflict, aka Gods, Mortals and Demons, the User choose a demon player named Zaytan as his form. In the first level the User played against an Angel Game Sprite. He quickly defeated him and crushed its skull, which according to Enzo is his finishing move.
The next few levels were not seen. In one level the User played a military commando and defeated him.
In the final level Enzo finally guessed which character the User was picking, a yellow ninja. Enzo fought well and won the first round against the User but lost the second round. In the final round, The User sliced Enzo's right eye. Just as the User tried to hit him again, Enzo managed to break the User's blade weapon. The User then knocked the exhausted Enzo to the ground. Realizing he couldn't win Enzo had an idea, and clicked his icon once, changing it to Game Sprite Mode. AndrAIa and Frisket did the same, and the User grabbed Enzo's head and performed his finishing move, winning the Game.
Mainframe's leaders were devastated as the Cube lifted off and the System Voice announced, "Game Over, User Wins."
The User's form in this Game was saved as undeleted RAM. After the Viral Wars, Mainframe began to crash. All undeleted RAM was released into the system, including the User from the Immortal Konflict Game. Enzo got to fight this User again and got his revenge on it for taking his eye and trapping him in the Games by shooting him in the head.
The ReBoot Multiuniverse[]
Zaytan pretty much functions the same way as he does in the series. Although it was slightly different in A Lost Cause. After Enzo lost the Game, it shut down and became dark before the SWAT members showed up and escorted Enzo away and held Zaytan back as his eye was being replaced.
In System Shock, Mewtwo regretted on not protecting the little Sprite from him, and so he reluctantly held back and watched Matrix have his revenge.
