History
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.
