This page is a candidate for speedy deletion. The reason given is: Although what's written here is true, Shadow wasn't even around when Gamma was introduced. It really dosen't make much sense to have an article about him here.. There may be discussion about this deletion on the discussion page.
E-102 Gamma is a robot from Sonic Adventure. He was around before E-123 Omega and some say that SEGA made E-123 Omega to replace E-102 Gamma. They both have simliar attacks. E-123 Omega was first shown in Sonic Heroes, after E-102 Gamma died.
