E-123 Omega 

The last and most powerful of the E-series robots and my personal favorite character from the Sonic the Hedgehog series. His wide arms contain all matter of weaponry and machinary. So far, he has appeared in three games. He's a playable character in Sonic Heroes, he's a hero character in the Shadow the Hedgehog game, and he's in the "Sonic Heroes" movies in Sonic Mega Collection+Plus. I think that's too few and am planning to work in Sega and make a game called someting like "Omega's Revenge"

Shadow the Hedgehog, Rouge the Bat, and E-123 Omega make the powerful Team Dark
