While I may be bi... there are a lot of people/characters I'd "switch" teams for (meaning going gay or straight razz )

Top two real peoples-
Johnny Depp (that's a big DUH! I am sure lots of guys would turn gay if they could have Johnny XD)
Keira Knightley (I think she is beautiful)

Seems I have a thing for Pirates I guess.

Fictional Characters (there are a lot so let me pick out the top few)
Abe Sapien (from Hellboy; weird, I know... but who cares, he's just awesome)
Jet Enduro (from Wild Arms 3)
Suki (from Avatar: the Last Airbender)
Motoko (from Love Hina)

And apparently I like fish-men, robot boys, and female warriors too... it's like one big sci-fi movie in my head.
