An older prototype of the current Vector model that fights with a Plasma Gun. Omega was long deemed faulty by its creator for being too compassionate. After hearing that it has a "heart", Omega searches to find out what it is before its power supply runs out and shuts down permanently.
After failing to gain answers from Bilstein, Omega soon encounters Ele, who thinks that its another killer Vector robot. Ele soon realizes Omega's true nature and explains to it that the "heart" the robot wants is something that is felt. As soon as Omega figures out what Ele said, its energy runs out. Many years later, Omega is found by a group of kids, one of them pointing out that the robot is "smiling".
