America is in a weird spot because even though Xochitl shares the age the character was supposed to have on her first appearance, the Gillen version which actually inspired and popularized the character as she is today was older than that, so I still side-eye them for casting her so young when I know for a fact they weren't looking at that Vengeance comic book as an inspiration for the MCU character. Even Xochitl said in an interview recently that MCU America is different from the comics due to her age and inexperience, and that really shows in the way they portrayed her in the movie.
The only reason I give them a pass it's because America is so disconnected from the original Young Avengers team that I don't mind if she ends up being younger than them. She was always an ''outsider'' who just joined them because of Loki's shenanigans, and I guess this is something that can still be done even with her being younger.
The sheer level of disrespect towards miss Katherine Elizabeth Bishop when she was arguably the most useful person when the Young Avengers battled Kang. Like, sure, Nate was the one who gave him the final blow, but only because Kate was the one who disarmed him and made him vulnerable. All of that while still being able to stand still (something you can't say about poor Patriot over there LOL).
It's fan art. The only reason why it's being shared it's because of a stupid ass Twitter user called ''Moth Culture'' who does nothing but spread fake news and misinformation.
