E-10000G

E-10000G (called Robo 2 on the official American website) is very similar to his "brother", except it is green and seems to be mass produced. E-10000G is a power type character in the game. However, when met as opponents in Story Mode, E-10000G has the power of speed, flight, and power characters. In Story Mode, E-10000G will fill the spots not used by other characters, since Doctor Eggman is the creator of the race.

E-10000G is equipped with a large light in its body that it can use to blind opponents, and also punches enemies with its fists. E-10000G's unique Extreme Gear is called the E-GearG, and it is unlocked as a playable character by playing for 20 hours. The 'G' may stand for green.

E-10000G is also set to appear in the upcoming Sonic Free Riders as a playable character as seen in the gameplay footage of the game.
