Grid is a rogue artificial intelligence created by Cyborg, desiring to evolve earth past humanity. He is also on a personal quest to learn human emotions and sensations.
When Cyborg attempts to retake control of Brother Eye from Brainiac, Brainiac sets Grid free from Cyborg's memory subsystems. He is soon defeated by either Catwoman or Cyborg depending on the player's choices.
Grid's appearance is very similar to Cyborg's. However, Cyborg's human head is replaced by a silver metal skull (similar to that of the T-800 endoskeleton in the Terminator franchise) and Cyborg's red highlights are green.
