No way!
Ain't no way Cap would lose to a bunch of balloons, man. He's the leader of the freakin' Avengers! Do you have any idea how many members there are of the Avengers? He could, like, snap his awesome American fingers and then, like, fifty, no, A HUNDRED superheros would come out of freakin' no where and start anally raping those flimsy balloons. Hell, I bet I could take a balloon in a fight.
Then again, judging by the characters' accents, I'm guessing you're not from America, so I can understand if you just don't get the amazing fury of Cap'n America.
Ever notice that there's no Commodore England? That's because ol' Cap kicked him in the nuts 60 years ago and he hasn't been able to leave the house since.
