These clones wear a white jumpsuit and have a weapon that fires white projectiles that leave its target unconscious. These projectiles follow its target and go through walls.
When Twinsen gets hit by one of the supergroboclones' projectiles, he falls unconscious, and is taken to the nearest prison.
After Twinsen acquires Fire Ball, the weapon able to hurt supergros, they start firing red projectiles that also follow the target and go through walls, but do not knock out, doing a lot of damage (20 Hearts) instead.
