I'm the mom of Shigeru so I can tell you that there is 7 new types:

-Pasta type (Sylveon, helioptile and "Spaghetto" a kind of gangstah with ravioli on his head).

-niggah type (every black pokemon)

-handicap type (Dunsparce, and a new pokemon named "Trisomix", which has a really cool design)

-Fairygate type (every pokemon in the game have this type but it's "hidden" and provides the move "autism" power: 0 PP: 0 Acc: 0 Poison type.)

-bacon type (Emboar is now bacon type)

-Fire/fighting type. (All the fire starters have it and loses their other types.)

-Sound of Light Type: All the new legendaries have it but it's "hidden". It provides weaknesses to all the type and a 6x weakness to Dragon.

New mechanics: Some trainers are "racist" so you can't play "niggahs type" and "handicap type" against them.
Ice is weak to all of the new types.

New pokemons:
Starters don't evolve except Fennekin which evolve into a fire/fighting pokemon.

Spaghetto: Pasta/niggah
Trisomix: handicap
Garchomp evo: Dragon/ Fairyfags/ground/fire/steel
Xerneas: Ice/Dragon
Yveltal: Poison/ground
New legendary:
Zexolian: Pasta/Normal.
