To get started;
My favorite Hero ; The New 52. Aquaman
Why; Aquaman has a generally young storyline and has a lot of room to expand and become better, and is almost untimely unexplored potential. The New 52 story has blew new life into him as he is devolving a nice storyline, with a lot of opportunity to intertwine with the Justice League and The Others (which it already has).
If anyone has questions about Aquaman, I think I could answer a few.
It doesn't have to pertain to DC or Marvel, can be any comic book character.
