Suggested by iKnowledge Nighthawk is a guy who’s definitely had some good character arcs over the years. He started out as a two bit villain and eventually became a hero that you could rely on. He’s not particularly powerful though and Lex has had many super forms over the years. Lex merged with Brainiac on one occasion after all and he got Superman’s powers at another time. It wouldn’t take him long to think up a plan to take out Nighthawk with. The guy needs a big power up to match Lex. Lex Luthor wins.
