first favorite is bulba (its so fcking cute), second is gyara (op sweeper in competitive), third is probably going to have to be gengar (hypnosis + dream eater/hex combo).
I like.... Torterra and Wishiwashi! Lucario is also one of my favourites too. The gen 8 Wooloo is pretty cute... and so is Rolycoly... DANG the Galar region brought some goodies.. But don't get me wrong, there are a lot of of pokemons I love.
