What relatively unpopular Pokémon would you want added to the game

I really like the idea of having five unpopular unova pokemon debut.

The three elemental monkeys would fit the game’s aesthetic so well to me. I’d also give them berry burst to make them uniquely strong team members since it fits in with their gluttony ability. My only issue is I’d want an event where you could at least get one evolution stone of your choosing by completing a mission because I need to save points for main skill seeds lol.

I’d also like trubbish to be introduced as a stockpile charge strength pokemon like drifloon.

And vannilite just because it’s cute :) maybe it could get extra tasty?! It would be a good reason to visit snowdrop more often

What are your niche / unpopular pokemon you would want to see?
