I don't find myself identifying strongly with characters, so this should be fun.
If I can be stupid, Max from Max and Ruby, due to how he keeps himself entertained, and a little how he is socially. Although I'm more shy. (but that's a tv show. XD)
L Lawliet, of Death Note, and a little Sherlock Holmes socially, though their genius is unmatched. XD
In a movie... maybe Papillon (never read the book), or Everett from O Brother, Where Art Thou. Something about them, I dunno. Hah.
