If you were to make a new type, what's would it be?

That's actually not bad I always kinda thought it was weird that there are so many Pokémon from space but they have no one common trait of any kind…
I'm guessing it would go onto Clefairy and Cosmog and Lunatone…

I always had a weird idea for a Sharp type. For Pokémon like Greninja, Kingambit, Virizion, etc

I think a new type would cause more harm than good, but we should change Flying to Air or Wind.

"Flying" is… not an element. What does it mean to be a Flying type? It's been a messy notion ever since the Levitate Ability existed.

The Ethereal type, basically for mystical things, magical beings, like dragons and stuff, it’s super effective against Fighting, Ghost, Fairy, and Psychic, and it also weak against Psychic, ghost and dragon. It resists Fighting, Steel, and it has a unique property where if a Pokemon terastalizes, it can ignore the type it turned into and hit the Pokemon like it never terastalized (I put to much effort into this)

But it's the OPPOSITE case with water. Because Grass gets nutrients from Water, Grass beats Water. I think Grass should be RESISTANT to Light.
