wow, I feel like Jason Lee's character in mallrats, so here goes, for protection I would have the x-mens wolverine, sure superman could fly me out of there and so on but I did some thinking and here are the reasons. Wolverine regenerates, If we can't find food, I'll eat his right arm and the next day it's back to normal, The claws, he'll kill anything that messes with me. He's got that whole sense of smell and he's like a wild animal, he can find himself out of anything.
Opposite sex for various reasons. Here is where my brilliant mind shines, sure wonder woman is hot, damn she's a goddess, catwoman has that whole cat thing going on, but my choice would be, wait for it, wait for it. Mystique, sure she's all blue and all, but if I'm going to be in a desert island I'm either going to get bored eventually or something to that nature, but nothing beats saying to her "you know what, today I'm in the mood for halle berry, or eva mendez" Or someday when I'm in the mood for something freaky "You know what, leave the blue on"
