E-106 Eta is a character who appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was the seventh unit in the E-100 Series line, created by Dr. Ivo "Eggman" Robotnik.
E-106 Eta was created sometime between 3236 and 3237, possibly during or after Dr. Eggman's campaign on harnessing the power of Chaos. Apparently, it went to West Robotropolis, only for it to be found by E-102 Gamma. Eta was then destroyed by Gamma.
