E-123 Omega

E-123 Omega, or, technically, E-123 Ω, is a fictional robot from the Sonic the Hedgehog video game universe, first appearing as a fully playable character in the multiplatform game Sonic Heroes, which was first released in Japan on December 30th, 2003. His character designer is either Yuji Uekawa or Takashi Iizuka. He bears a strong resemblance to another character in the series, E-102 Gamma, who is part of the same robotics production line. In the games, he was created by Doctor Eggman, and is out to destroy him due to lack of respect and want for revenge. Omega is 150 cm tall (4' 11") and weighs 1,230.512 kg (2712.77 lbs). He has the capital Omega symbol (Ω) painted on his shoulders, in contrast to all the other E-100s, which had the lowercase Greek letter (ω), possibly representing that he is the most powerful of Eggman's E-Series (though the Original set of E-100s from Sonic Adventure had various Greek Symbols). Though they may have used the capital letter because it's far more noticeable and well known than the lowercase. Omega has helped Shadow (and to a lesser extent, Rouge) in several Sonic games, and while not being a major character, is popular enough in his own right. Recently however, he has made less appearances in Sonic games, as he only seems to be in the mainstream canon games as a teammate to Shadow.
