Avengers #234 goes into the Nights of Wundagore stuff as well. And isn't really focused on Magneto. #104 is also when Pietro goes missing. But your focus is on mutants because that is your interest. It's also not what the show took from those issues because those parts do not have much to do with Wanda. None of these are "popular." Wanda wasn't popular before the MCU. There are issues more central to her, her origin, her powers. But nothing was popular or famous. HoM was infamous, but for what happened to mutants. If mutants weren't depowered, most would not know about it.
It's not a Wanda story and nor should it be. Her story (her show) should be about her. Understand? Mutants and Mags will get plenty of time in the MCU. Also, Force Works was a terrible cartoon. The book was better towards Wanda but definitely not Tony. 90s is not the best pull for stories for a lot of characters. Until it got closer to late 90s.Well, Wanda IS a mutant in these shows.
