I play Sylar, who I would love to throw against a Claire (not necessarily shippy if you'd rather not go that way, I just love their potential for interaction). I play Elle too. I also play the Doctor from Doctor Who, who could be an interesting counterpart for Claire. I play Spock from Star Trek as well. My full list of characters is here if anyone jumps out at you!
I also play Hermione, if you're looking for a line for your Harry. Just saying.
