He is just another Symbol of the Capitalism, since he was born in the 40's... Is he better than many other Super Heroes who can actually replace him? Moreover, a Super Soldier isn't supposed to hide dehind a Shield! The "Super Epic Fail"!
no one can replace him. because he thinks stuff through. iron man rushes in to battle. and that's why he gets trapped. a lot. cap plans, then attacks, and wins. and enough with the names. all it does is show your immaturity.
Well then, why do exist all these Super Heroes, if they're not good as your pathetic Captain A--h--e? All the Glory to him, then? The one and only? The smartest Super Hero? AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA! I would rather prefer Achilles to him!
no one can replace any superhero. that's what I like about Marvel. the characters aren't repeats. they all have unique abilities. and he is the smartest super hero. he's street smart. and I don't like cap.
