E-10000R can be unlocked as a playable character after fifty hours of gameplay.
Right before the Egg Factory race of the Heroes Story Mode, E-10000R accidentally walks into a fight between Knuckles and Storm right after it gets confused about Storm's Extreme Gear, the Type-S. It gets severely damaged when Knuckles accidentally punches it from behind. When Storm tries to give Knuckles a real punch, he punches E-10000R, causing him to malfunction and shut down. Explaining why it wasn't in the Egg Factory race, why he was late, and why he didn't make it into the rest of the Tournament.
In the Babylon Story Mode, it came back for revenge and it tried to capture the heroes with a gang of E-10000Gs. During this confrontation, it had visible damage from the earlier battle. It chased them in the Sky Road race, but they eventually got away.
Powers and abilities
E-10000R is a capable Extreme Gear rider, who can move expertly at high speeds, perform both complex and impressive tricks and body movements while in mid-air, and engage in combat with other Extreme Gear riders while riding its own Extreme Gear. In addition, it is equipped with the same kind of engine as Metal Sonic, enabling it to go even faster and move with great maneuverability.
E-10000R also possesses a detachable head which it can use to distract opponents. It can even use its head as a weapon, namely by tossing it at an opponent, after which it will fly back to its body. It also possesses parental authority to give direct instructions to all E-10000G command systems.
In Story Mode, he sounds just like the other E-10000Gs, but when playing as him after unlocking him, his voice sounds a little higher-pitched.
Like all the other robots from the E-Series, this one has other robots that look similar to it, but with different colors patterns and numbering. For example, E-10000G is the clone of E-10000R, but in the color green, a single stripe on its hat, and the number 01 on its back rather then red, two stripes on its hat and the number "00" like 10000R. Also, there are two other robots in the Egg Factory course that appear to be yellow or purple clones of E-10000G except with a floating body in place of legs.
