Omega's only goals in life are to take revenge on Dr. Eggman for wasting his potential and destroy the doctor's other robots to prove himself superior. These two goals are absolute above all else in Omega's eyes. As a result, he tends to be extremely headstrong, reckless, aggressive, and destructive - decimating anything that gets in his way.[7] Most noticeably, before the start of the War to Take Back the Planet, he performed what was supposed to be a recon mission on Eggman's base and rather than sneaking in to get info, he stormed in guns blazing in an effort to purge the base of every robot within, despite his orders having nothing to do with extermination.[8]

Like E-102 Gamma, Omega has a free will and a personality. However, he is considerably less noble than Gamma; while E-102 destroyed only what needed to be destroyed, Omega destroys anything that could possibly pose any kind of threat to himself or his mission.[9] He thinks other Eggman robots are inferior to him,[10] dismissing them as "worthless consumer models," especially the E-2000 models.[11] He hates side tracking especially when it comes to locating Eggman.

For Omega I want Jon but any voice works! If you think your voice for him is better go right ahead and do that!
