#Knickstape
Bucky was helping break it though it wasn't just Sam. Walker almost ended him if Bucky didn't jump in before that after he broke his wings.Well like I said above, I don’t think he is but not by much if at all.
I forget where and who I read it from online, but basically, John in the MCU is as powerful as he is because of his already exemplary training and experience as well as being in at a high level physical peak when taking the serum (in which Steve was not).
The serum is said to have increased what you already have, correct? Well this was a knockoff
But I’m not seeing Falcon break Steves arm. So stronger, I don’t think so. More dangerous... probably. Less mentally stable... definitely
Sam holding on to Cap’s Shield with Bucky holding on to Walker

its not close at all based on what they've showed of Walker
