E-105 Zeta is a member of the E-100 series of robotic units made by Dr. Eggman. When tasked with finding Froggy, Zeta was ousted by Eggman for capturing the wrong frog. Later on he is forced to undergo major reconstruction, becoming a stationary, tower like defense unit rather than his original humanoid design. The enormous machine is eventually defeated at the hands of one of his "brothers," E-102 Gamma during his infiltration of Eggman's ship.
