How is Normal one type anyway? You could split entire Sound and Beast types off of what is under it.

There are more water type Pokemon than normal types, which makes water type more normal than normal type.

Honest lol

just a sentient mass of stem cells perfectly Normal

I know in the TCG that Normal type is represented by Colorless energy, which basically means any type in the spectrum. Arceus is also Normal type even though they should technically be every type based on lore.

having a Normal one

Same reason Arceus and Type:Null/Silvally are

Ditto<T>

Normal-Types can learn and use a move of any type, right? Ditto can self-replicate a Pokemon’s appearance and moves, so it can use any Pokémon move of any type, so it’s a Normal-Type.
