I am Omega, the Ultimate E-Series Robot.
~ E-123 Omega

E-123 Omega is a robot from the Sonic the Hedgehog series, first appearing in Sonic Heroes. He was Dr. Eggman's latest creation, who took revenge on his creator for sealing him in a room. He teamed up with Shadow the Hedgehog and Rouge the Bat to take down Eggman.


Omega was created by Rouge the Bat went searching for Eggman's secret treasure in his base, she accidentally reactivated Omega when she released Shadow from a stasis pod. Mistaking Shadow for an Eggman robot and following his new mission, Omega attempted to take out the hedgehog. However, the three of them then started their search for Eggman at Seaside Hill and Ocean Palace before coming face-to-face with the Doctor himself (who was really Metal Sonic in disguise) in his Egg Hawk.hey arrive at a lab and Tails hacks into the computer system, locating the results of an experiment called Project "Mother". Shadow was disappointed they didn't find more to help, but Sonic just focused on the fact that it was useful all the same before speeding off. Omega then asked why Shadow gave Sonic information, and the ultimate life form replied he was just happy to let Sonic do all the racing around. Omega found this hard to understand since Shadow and Sonic's abilities were equal according to his data and Shadow just replied that data would not tell him everything, leaving the automaton stumped.
