E-123 Omega

E-123 Omega (オメガ, Omega ?) is one of Doctor Eggman's E-100 series robots, specifically designed to contain and control Shadow the Hedgehog. In his first appearance in Sonic Heroes, Eggman seals Omega within an abandoned base, along with Shadow, until Rouge the Bat releases Shadow from his stasis pod, accidentally reactivating Omega.[46 ] Infuriated at being sealed, Omega decides to team up with the other two in order to obtain revenge on Eggman and prove that he is the most powerful robot of all.[47 ]

He returns with the same goal in Shadow the Hedgehog, and teams up with Shadow in certain levels to destroy Eggman's robots. During Sonic the Hedgehog 2006, he is playable after Rouge orders him to support Shadow many years in the future.[48 ] He is also one of the secret unlockable characters in Sonic Chronicles: The Dark Brotherhood found in Metropolis.[49 ] Omega has appeared in Mario and Sonic at the Olympic Winter Games as a rival in speed skating and intense short track[50 ] and in Mario & Sonic at the London 2012 Olympic Games as a rival in the 100m Sprint.

Omega has an array of destructive weapons concealed in his arms, including machine guns, flamethrowers, missile launchers, beam cannons and rocket-propelled drills. He can also retract his hands in order to attach a spinning Shadow and Rouge in their place, either using the two as melee weapons or firing them.[46 ] Omega has jet boosters built into his back to help accelerate and hover, and a range of sensors in order to detect and locate enemies.&nbsp
