is professor x gay
Alex Summers and Armando Muñoz (Darwin) are two dudes who Professor X and Magneto recruit to join their team of mutants in When First Classpremiered, yes, I was struck by the chemistry between Xavier and Magneto - who wasn’t?.
Magneto was never gay; he was always straight, and his love interests were primarily women. Magneto and Charles Xavier were always good friends only, and there was never anything romantic between them. All superheroes and some supervillains have love interests.
Essentially, I'm wondering why I often see people say Magneto and Professor X are gay? Of course I obviously know shipping is a thing, and that two characters being close, regardless of gender or sexuality, is gonna have people saying they're together, but I'm wondering if there's anything that actually lends legitimate merit to the idea.
Professor X and Magneto's relationship changed forever when Baron Von Strucker and Hydra kidnapped Gabrielle as they searched for lost gold. Xavier and Magnus teamed up to rescue Gabrielle, revealing their powers to each other in the process.
