When Sonic confronted Eggman in his his fortress, an E-13 Guardbot broke Eggman's Chaos Emerald device when firing at Sonic, triggering a massive Chaos Control that sent everyone in the vicinity to Earth. On Earth, an E-13 Guardbot was deployed to stop Rouge the Bat and Topaz from stealing Eggman's Chaos Emerald, getting destroyed in the process. Several E-13 Guardbots were later summoned to help fend off an attack on Eggman's fortress by GUN's forces.
