Theory: A new Pokémon type to be introduced in Pokémon Sun and Pokémon Moon.

[Luke888]

Imho there's no need for other types, they only need to balance out the types they now have *hint hint Water and Fairy*. Imho Solgaleo COULD have a new type (type light ?) but Lunaala is 100% Ghost/Flying, it has bones and it flies, you can't co further than that...
