Loupetron is the seventh active of Douglas's Viratrons, created when Data Card 10 infects Caitlin's magnifying glass after she steals it away from the Lab Rats. A gentleman thief in personality, Loupetron's objective is to gather data on human greed & suck it out of collectors. Loupetron's right leg has the power of Douglas controlling it, giving him swift movement & high jumps. Loupetron can use his walking stick as a weapon along with his shoulder-mounted Loupe Bazookas to fire a single powerful beam. Loupetron is eventually destroyed by the Lab Rats in Custom Upgrade mode.
