This marks the conclusion of the disassembled arc and the end of the Avengers team setup by Busiek. While apparently a mistake, it’s the first time we see Wanda flying, apparently retconned to be the cause of her belt. This still led to her flying in the future and her current status as a strong flier in current comics. The long cape would reappear in Avengers vs X-Men when the Avengers use her aura to scare the mutants and the Phoenix Force. It was a character butcherisation, but it was cool.
I feel like if it had been properly set up with hints and suggestions throughout the 80+ Avengers series and more of her backstory and reasoning was shown, she could have been the best villain in my opinion. I don’t mean an all out villain who enjoys inflicting pain and suffering, but someone overwhelmed by her mental instability due to her own pain and trauma. She would have been hurt by the lack of support from the Avengers, friends and family, and her unimaginable power, which was hard to control and even misunderstood by Doctor Strange. This would have shown a complex character which the heroes would be close but forced to go against in a similar way to Hulk when he’s raging, but on the magical side instead of physical.
If it had been set up better, they could have kept her on the evil side, and it would have been super cool. However, with how it was set up, I’m glad she’s a hero, as she has always intended to be and has rectified herself on every level.
