There is only one answer.
Og thor
all of them ?
The Captain for sure. Give him the Magneto treatment and make him good against all the skill class mercenaries and agents. He trained the majority of Avengers, he knows how to throw a punch
OG Cap, at least, should be immune to Atrophy, imho.
Captain America. He’s too weak in the game. It feels like he didn’t get the super soldier serum. It would be nice if they made his special attacks unblockable when he throws his shield and getting furies when he’s blocking
All of the OG Avengers should receive the Hulk treatment at bare minimum. I would prefer a complete overhaul like Iron Man but that would just take too long
Black widow no
Hawkeye no
Because those are lame avengers even in the movie.
Thor yes
Cap yes
