A/N: Yeah, I'm just going to get it out of the way now. Even if they put Mai in Ultimate, it won't matter. Why? Well, here are my reasons.

She'll either get the same treatment that Zero Suit Samus Got in Ultimate.

Or The Same Treatment Bayonetta got where they blackened out parts of her clothes back in smash 4. 

Or she'll get a mixture of both treatment.

And before I get someone in the comments saying that it's hypocritical of Sakurai to not allow her, yet he's got Palutena, Bayonetta and Zero Suit Samus in the game.

Compared to what Mai's got going on, those 3 aren't near that level of revealing. Especially at the lower body.
