This is gonna sound odd, but I kinda respect Nanu's Alolan Persian. That cat almost swept my team first time I fought it. Reminded me then and there that you should never judge a book by its cover. ^u^;
I like Olivia's Lycanroc. Not really cause I like the Lycanroc its self, but because my shiny Lyconroc kicked her Lyconroc's butt. And they were both midnight form, so it was even better.
I liked Kahili's Skarmory. It is the only Elite Four Pokémon to still give me a hard time in the postgame.
I'm gonna go with Hala's Crabomidable. Crabomidable is one of my favorite Pokémon in this gen and Hala is just great.
Olivia's Probopass. It's kinda a love-hate relationship, because I practically swept the League...with the sole exception of that tanky beast. Took me so long, and Thunder Wave is now officially on my 'least favorite moves' list. My WHOLE TEAM got paralyzed, and you can't heal more than one per turn. It was a NIGHTMARE.But I won in the end An engaging battle, anyways. #MissingNo
