Lobo had his own comic series dude. It was all through the 90's. Then it ended sellin'. I got the two origin miniseries, and the one when he gained immortality through beating up satan and the god squad lol.
If we would do the most overpowered comic hero, Lobo would own. Completely unbeatable bounty hunter wich can regenerate from a single cell (since he beat up all dem gods) and can create a thousand clones from one drop of his blood. Also, did i mention always having millions of nukes with him...
