well, since we're looking at multiple characters... gonna go look for a second character too.
No, no, what I'm saying is that both Cap and US Agent are on the team, which seems redundant to me. I'm not playing them both, someone else is playing US Agent.
That said, if you want to play multiple characters, go for it.
The two characters are really nothing alike. Captain America is a better fighter and has that unique shield, but US Agent makes up for it by virtue of super strength and durability. Walker has a much more brutal outlook on crimefighting.
I've never known much about US Agent, so the profile I received is about the extent of my knowledge. I'd always thought he was just a sub-par Captain America wannabe and that they butted heads before. I do see, though, that as far as personality and experience is concerned they are nothing alike. Chances are they'll continue to clash throughout this RP. But hey, a bit of conflict is good xD
