My Nuclear Apocalypse Team

Let's face it, the Zombie Apocalypse isn't the only thing that could destroy the world. Plus, this seems, unfortunately, more realistic. I want to see what you guys come up with for your own team.

Rules

1) If you use a character from a movie, book, anime/manga, etc., use only one character per story or franchise.
             Example: If you use Katniss from The Hunger Game Series, you CAN NOT use The Hunger Game Series anymore.

2) Don't use overly powerful characters. Superheros and Super villains are NOT allowed.

3) You can use OCs, but again, no overly powerful ones.

4) Please Please Please! Credit me and send me a link! I really want to see what you guys put! I love other's creativity.
