2. Lobo
Lobo, who was originally introduced as an outright villain, has evolved in to more of an anti-hero and would make for a great, dark Superman movie if he was the opponent on screen. The Ultimate Bastich, the Main Man, the 'Bo, Master Frag, Mister Machete, Scourge o' the Cosmos, Lobo is the last survivor of the Czarnians from the planet Czarnia. He's an intergalactic bounty hunter who zooms around space on his souped-up motorcycle going after his targets. It would be awesome to see a live action version going after Henry Cavill's Superman, as a fight between the two would be epic. Lobo possesses superhuman strength, stamina and durability, as well as superhuman senses (such as an incredibly good sense of smell), a regenerative healing factor that allows him to regenerate even from a drop of blood (essentially rendering him immortal) and a genius level intellect (which not a lot of people know about him). He would pose a real threat to Superman if the Kryptonian had a price on his head and comic book fans around the would would go nuts to see the crazy hunter in a big budget flick.
