If you could add a new type to the Pokémon games, what would it be and how would it work?

Cosmic/Space - weak to Dragon and Steel but resists Rock, Ground and Fairy.

Light. Always seemed weird that there was a dark type but no light type. As for how it works... not sure. Effective against dark, ofc

Synthetic. There are a whole lot of "man made" Pokémon or ones that posess / mimic "man made" items (Porygon, Voltorb, Klink, Meltan, Bronzor, Honedge, Magnemite, Chimeco, Baltoy, Sandygast, Trubbish, Litwick, Carcol, Vanillite, Sinistea, Comfey, ....) that are currently shoehorned into other categories and not always fit properly IMHO. For example, I can understand why Rotom is an electro-Type as it is basically a sentient bolt of electricity, but why is Dhelmise a Ghost/Grass type? It's a sentient anchor but somehow not a water-steel-type? And Sigilyph is a prime example of "WTH is that even" that only got shoved into the psychic-flying niche because of its attacks. Why are blobs of whipped cream and sentient keychains "fairy"? (Alcremie, Klefki) What about Unown, which are literally letters with eyes?

If there was an "this is an item that somehow learned to move" category, it would instantly have a couple dozen prime candidates, and each new gen introduces more of them (the legendaries of the newest gen are basically motorbikes, for example)

Human type pokemon, you know exactly how it would work.

Beast-type. It would basically be a fighting/normal type. There are already a lot of potential pokemon that are shoehorned into either normal or fighting that would fit the bill IMO (Tauros, Primeape, Kangaskhan, Slaking, etc).

"Normal" type always had a really weird variety compared to all the other types. It felt like a catch-all to pokemon they wanted to include, but didnt know how to classify them. Like, somehow Chansey, Raticate, Porygon, Ditto, and Tauros are all part of the same family? I dont buy it.

Energy type.

Purely because it would be hilarious for the TCG to have "Energy Energies"

It would be LARGE PRINT and it would work by me being able to read it without a magnifying glass.

Flying.

I know that’s already a type, but so many are flying/normal that it’s super diluted. I’d change that.

I think we could add Air, its clearly the type that is missing.

Rather then flying have them use wind based moves.

Not very effective against fire, because it would help boost it.

Supper effective against ice because it dries it out.
