E-113 Xi

E-113 Xi was an E-100 Series robot.

History
Xi was the fourteenth E-Series robot created by Dr. Eggman. At some point it was stationed at the Efrika/Yurashia border waiting for E-102 Gamma, but Gamma destroyed it and freed its Mobini battery. After the battle Gamma surmised his creator was actively trying to destroy him. (ASUB)
