E-101 Beta

E-101 Beta is a minor character from the anime series Sonic X. It was one of the first robots in Dr. Eggman's E-100 Series, but was later upgraded to E-101 "Kai".

History
His role in the series mainly mirrors of that in Sonic Adventure. Beta was created as one of Doctor Eggman's E-100 Series. After failing to capture Froggy, Beta was taken apart by Eggman and rebuilt into a stronger form. When Gamma returned to the Egg Carrier, Beta attacked him, causing the two to fight each other to the death. During the fight, Gamma tried to reason with Beta that Dr. Eggman was the evil person but Beta refused to listen and simply continued to attack him. Beta and Gamma eventually struck their weapons through one another at the same time which destroyed them both and released the Flickies trapped inside of them.
