E-102 "Gamma" was the third robot of the E-100 Series line created by Dr. Eggman. Although Gamma was created by and made to work under Dr. Eggman, he ended up abandoning his programming in search of something more, due in part to an encounter with Amy Rose and her Flicky friend. After spending over a year fighting Dr. Eggman's forces, Gamma met his end at the hands of fellow robot E-123 Omega. However, he was able to upload his free will into the other robot, thus leaving Omega to carry on his fight.
