E-107 Theta is a character who appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is the eighth unit in the E-100 Series robotic group created by Dr. Ivo "Eggman" Robotnik. E-107 Theta was created either during or after the time of when Eggman harnessed the power of Chaos.
E-107 Theta 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 Robotropolis, where the hazardous environment allegedly cause the target's signal to disappear from E-102 Gamma's data log. This made Gamma assumed E-107 Theta was destroyed by the environment.
- E-107 Theta was originally going to make a return within the Post-Super Genesis Wave timeline, according to the original official solicitation of Sonic the Hedgehog #258. However, because Theta was previously mentioned in the Pre-Super Genesis Wave timeline (specifically during the Light Mobius saga) and the fact that Ian Flynn wanted to avoid any further lawsuit with Ken Penders (this was immediately after the lawsuit between Archie Comics and Ken Penders), Theta was replaced by E-106 Eta.
