E-122 Psi is a character mentioned in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was the twenty-second unit in the E-100 Series line, created by Dr. Ivo "Eggman" Robotnik.


E-122 Psi was created sometime between 3236 and 3237, possibly during or after Dr. Eggman's campaign on harnessing the power of Chaos. At some point, it surrendered to E-102 Gamma in Deerwood Forest. Gamma was conflicted about having to destroy his brother, but he ultimately decided to do so to free its Mobini battery, logging the new emotions of surprise, pity, and a new variant of regret into his databanks.[1]


  • In the video game Sonic Battle, the robot designated as Phi was E-121 rather than E-120. According to Ian Flynn, this misnumbering is the real-world reason for Gamma's memory error.
