Lobo

Born with superstrength and psychopathic tendencies, Lobo found his true calling as a vicious intergalactic bountyhunter. He pursues his prey with unstoppable ferocity and leaves a path of destruction in his wake. He beat up Superman, knocked the Justice League around, fought with and beside L.E.G.I.O.N., and even took on Darkseid "mano a mano". (He lost.) Lobo uses various "tools of the trade" and also has the Czarnian ability to replicate his cells as needed. Altogether, the "main man" is hard to stop.
