All 88 new Pokémon introduced in gen 7 (at some point in their evolutionary line) have either a signature move, a signature ability, or both. I dislike— no, I hate this trend. It needs to stop. We don't need to give something unique to all the Pokémon. Just create some "normal" Pokémon for gen 8.‬

(Oh and Z moves are counted too)

Melmetal- Double Iron Bash (Melmetal IS included in gen 7)

Now, I understand it's okay to give signature moves/abilities to legendaries/mythicals and the starters. But what I mean is that we don't need to give them to every single Pokémon introduced.

EDIT: I forgot to add Bruxish has Dazzling.
