Sure 5 is the brother of Mac and shares the same powers. Sure 5 was an ally at first but sadly Mega Mind found him in the ruins of his blown up headquarters and he turned Sure 5 into a cyborg. Now Sure 5 is a living Robo-Hunter. Sure 5 is now Mega Mind’s number one henchman. But Sure 5 probably was still himself somewhere deep inside him. Sure 5 was forced to be a villain…he didn’t choose it.
