Charcaters that aren't OCs that I have are Sherry Birkin, Knuckles, and Dark Leonardo if you want to go back to my LJ days there's Mikey from TMNT 2003 too
Well that changes depending on how often they've annoyed him. I would say it's a toss up between Dark Raph and Dark Don, since DD annoys him less often but pokes DL in ways that he resents for longer when DR only picks fights over food or when he loses his temper so it's more often but DL gets over it faster.
Nott: Comics (Technically not a genre but that is what he'd say.)
Eliza: Fantasy!
DL: Books? EW!
