[Western Crossover] My Name Is the Group

[My name is Legion, for we are many] David, who grew up in China, goes abroad, and only then realizes why his mother left him with his maternal grandfather. The world abroad is unbelievably extraordinary! Ordinary people? Mutants? Wizards? Aliens? Demons? Vampires? ... Somehow, humans have divided themselves from all the other beings living on Earth, completely unaware that they are not the masters of this world. Nor do they have the right to decide who gets to live here. ★★★ David says: There's a law back home that says you have to look human when you go out, but everyone's free to be themselves at home. So why are nonhuman beings abroad either superheroes or supervillains, or else poor little victims? ★★★ CP: Quicksilver Potential pairings: David's parents are both alive, but separated. Includes EC, Wanda and Vision, Havok × Polaris, and Scott (Cyclops) being the target of affection from Wolverine, Jean, and White Queen. Notes: 1. Tons of headcanons. 2. Some canon characters may become alternate personalities. I'll mention it in the author's notes if I decide to include this. 3. The protagonist is adored by everyone. I really am interested in the multiple-personality-in-one-body trope. 4. If the writing goes well or inspiration strikes, the story might later turn into a crossover with other anime worlds, though it could also get discontinued. Theme: [My name is Legion, for we are many]
