>>50478033There's 393 alternate forms for Pokemon, meaning there's only 1298 mons including forms.
If we're just talking about mechanically different forms and not things like the 63 Alcremies or 28 Unowns, there's:

There's also Cherrim, Meloetta, Aegislash, Wishiwashi, Mimikyu, Minior, Eiscue, Morpeko, and Cramorant, which change forms mid-battle with their abilities, but since the abilities to use those form changes aren't optional, I don't count them. If you want to, that's 251.
