I really don't think they are doing Magik in X-men 97. Doesn't fit the extremely nineties vibe of that show. But yes, if they do end up using her in that or any other cartoon then I have to assume that she just shows up fully costumed and then do her backstory in flashbacks. A full Storm & Illyana-esque story is not going to happen (and I am honestly amazed that it happened in the comics personally since it was back when the only X-comics were Uncanny and one Wolverine mini iirc.)
Marvel Heroes game of the century never forget. Magik being voted in by the community was clearly proof that everyone loves her when given the chance (
)
Pretty crazy that Tara Strong voiced her both in that and the animated series 20 years earlier. And apparently she was credited in 4 episodes of the show according to IMDB which is far more than I would have thought so maybe she does have a chance to show up again.
