What if they added, like, space type? Just think about it. Deoxys and Rayquaza, Cleffa/Clefairy/Clefable, Musharna/Munna, Lunatone and Solrock, [Don't forget most pink pokemon that evolve from a moon stone, I still don't know why they do that...) plus a new, at minimum 100 'mons. (I'm not saying 100 space types, I'm saying that's the smallest Pokedex they can make.) Plus they could make moves like cosmic power or moonlight space type... But sunny day would be pushing it... I'm just saying space/meteor type has potential in Pokemon...
"Space", as in everythin' beyond earth, ain't really applicable to be a whole type. In a way it would make more sense for a 'Mon like Deoxys, but I don't feel it'd fit in well. Outer space can't really be pinned as elemental in nature (Fire, Electric) or physical matter (Steel, Grass). Don't feel like it'd makes sense as a categorical type like Fighting, Dark or Dragon neither. Furthermore, types usually aren't decided by where a Pokemon comes from or lives moreso than why it lives there. For example, Water types aren't classified as such just 'cause they live in a body of water. Palkia sure as shit doesn't live in water, yet it's got Water typing.
The only new thing that would ever work as a type is light. Everything else won't work.
I do too, actually.
