E-123 Omega

E-123 Omega (Ｅ－１２３ "オメガ"?) is a fictional robot from the Sonic the Hedgehog series. He is considered a spiritual successor to E-102 Gamma who is part of the same robotics production line in the series. He was created by Dr. Eggman as the last and most powerful E-Series robot, and seeks revenge on him due to resentment of his abilities being wasted.

Omega was created by Takashi Iizuka at Sonic Team USA while he worked as the director of Sonic Heroes to serve as the Power Type character for Team Dark. Omega has helped Shadow and Rouge in several games and while not being one of the major characters of the series, is popular enough in his own right and has slowly established himself as a main character, often appearing in titles that require an ensemble cast.
