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. Gamma eventually short-circuited him, destroying them both and releasing the Flickies inside them.
