Post Ultra Beasts.

Honestly, Ultra beasts have some of the most interesting and amazing designs of the entire series (my personal favorites being Buzzwole, Blacephalon, Naganadel, Xurkitree, Kartana and all Necrozma forms) and have such fleshed out personalities in their designs. That combined with their prowess in battle makes them so fun to use and interact with and I am glad that Game Freak added them to the game.)
