Proper comic book wise, I've hilariously only ever read one issue of Spiderman and one issue of the Phantom. All I remember about the Phantom is he's a dude in purple who punches people. Mostly, I'd like to thank Wikipedia for saving me when I have no idea what's going on.

In other thoughts, clearly a dude in purple tights is the next character I'm bringing into this RP as a supporting cast member.

I'm not sure if graphic novels count, but I've always been partial to the Sandman series by Gainman. In particular, I absolutely love Death: The High Cost of Living...and really anything which focuses on Death as Gainman portrays her.
