He's trying real hard to be one of the good guys.
I liked the contrast between Wanda and Steve/Natasha in the fight with Thanos's lackeys in Infinity War. Wanda was probably WAY more powerful then the lackeys, but they attacked from surprise, kept her off balance, and she was distracted keeping Vision alive--so said lackeys were winning. Then Steve and Natasha show up, and they are LESS powerful then those lackeys, but they are trained soldiers who work together and use tactics to their advantage--so Cap and the Widow manage to win.Having rewatched the movie recently I realized that after Captain Marvel, Wanda may be the most powerful hero out there*. It certainly looked like she was going to take down Thanos before he went with the nuclear option.
*Yes, I realize that there is plenty of room for debate here.
The implication here (seems to me) is that Wanda has a lot of raw power, but isn't a trained fighter. Her training has probably focused on properly controlling her powers, not on winning fights.
In terms of raw power, it's worth noting that Wanda was winning UNTIL Thanos turned his battleship's guns on her, but Carol was able to defeat that ship, guns and all. So in terms of raw power, Carol would seem to have a clear advantage. On the other hand, in terms of bredth, Wanda can do a lot more with her powers (mostly because they haven't been well-defined in the movies). The only other hero in contention for "broadest powers" is Dr. Strange (though Iron Man with his nanotech was in the running too).Oh I definitely agree. She’s near the top on blasty power and also has mental tricks that haven’t gotten much focus as a good guy.
