E-123 Omega

E-123 Omega is a character in Sonic Heroes and Sonic the Hedgehog(2006)

History
E-123 Omega was created as the last of Dr. Eggman's E-100 Series robots, possibly inspired by the design of E-102 Gamma. Omega was designed by Eggman to prevent the release of Shadow. But being imprisoned infuriated Omega, and he abandoned his original programming to prove his power against all of Eggman’s machines. Since then, he teamed up with Rouge and Shadow, the people he trusts most. While Omega is largely emotionless since he is a robot, he is still capable of understanding those of others. He prefers to destroy anything that poses any kind of threat.
