Ooh, tough one, well, let me see:
First of all: I will take Mario Mario, just for the hell of it. It doesn't matter if he get's shot, but it'll be fine if he survives. He should stick to shooting balls and stuff, because nazi commanderhelmets have spikes in them...
Second: Captain Falcon. Hell yeah. Anyone who has played, or even seen, ANY smash bros. game knows a German could survive a Falcon Punch. Yeah, it's slow, but so be it. Guess I'll back the man up with something like...(see next entry please, failed attempt at dramatic entrance of real hero...)
Alexi Laiho: Children of Bodom's singer/guitarist. Shreds so fast all Germans will lose their eardrums, become disoriented and die from viewing sheer awesomeness. Anyone who can play solo's like that dunk deserves a spot on my team. He'll distract the Germans for long enough, so Cpt. Falcon can do his slow but increadibly awesome signature move(Just imagine: "Faaalcooon PUUUNCH!¡!11!1¡1!!"
Last but not least: David Beckham: Cannonfodder. He will go in first in a device I made myself: a super-duper armor systemthingy. What I won't tell him is that it's made of paper mache. I'm diabolical and don't like him. Gots problem wiv that?
