Superman. I know a lot of people think he's too OP but that's not really true when you look at his rogues gallery. Besides, the true value of Superman isn't in the fights it's in the character. Story lines like Red Son that focus on what he's like rather than what his powers are are always memorable.
I know I like to say Shazam a lot, and that this character is really mainstream (which just shows how great he is), but I've really loved this guy. There's just so much about him a fan couldn't tell a regular person in one conversation or sitting.
batman. and only batman. im not much into dc as much as marvel (which im not even hugely into either) super heroes and american comic stuff like all that just doesnt really interest me, although the movie adaptions i like. so i can easily sit down and watch all batman movies. maybe even superman too
