Lobo
Species: Czarnian
Enemies: Atrocitus, Anti-Monitor, Batman, Green Lantern, Santa Claus
Lobo is often painted as an antihero, which is technically true. He is a galactic mercenary who is willing to kill or capture anyone if paid enough. This can put him on the bad side of certain heroes, yet he might fight alongside him if his contract is to take down a mutual enemy. While he debuted as a major villain in the 1980s, writers quickly did not know how to use him. It led to Lobo being unused until the 1990s. By then, he was being used to mock Marvel Comics.
Marvel had gone to more of a gritty, overly violent side in this time period with the likes of Wolverine and Punisher. They decided to use Lobo in similar, but ironic and often weird ways. Instead of being a parody, fans loved him and that led to Lobo’s antihero status taking off. The “Main Man” is incredibly strong and fast as well as immortal. He can regenerate from nothing more than a drop of blood. This can be a problem as copies of him can pop up, so he might have to absorb these copies. Due to his immense power and abilities, he is one of the most powerful galactic characters in comics. This is useful for alien mercenaries.
