E-118 Tau is a character who appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was the nineteenth unit in the E-100 Series line, created by Dr. Ivo "Eggman" Robotnik.
E-118 Tau was created sometime between 3236 and 3237, possibly during or after Dr. Eggman's campaign on harnessing the power of Chaos. Apparently, Tau was ambushed by E-102 Gamma at the Dragon Kingdom at Yurashia, to which it was later destroyed by Gamma.
