I watched the Breakfast Club for the first time last week, and I noticed a strong similarity between Ally Sheedy's character and Michelle (Homecoming even borrowed one of her jokes from Breakfast club.) I feel like Michelle is essentially Marvel's version of that character, not an adaption of Mary Jane. I honestly wouldn't be surprised if she was just written into the movie as an homage to Breakfast Club, and naming her "MJ" was just an afterthought. I still don't think we'll see the comic version of Mary Jane in the MCU (at least with Holland's series), I can't see them having two characters at the same time with the name "MJ". I'm also curious where the name "Jones" came from. I saw it on one of the wikis, but I'm not sure if that's considered canon by Marvel or not. I have to disagree, I thought she had some of the funniest scenes in the movie.
