What are some of the best nicknames you’ve given to your Pokémon?

I'll start: I'm currently playing Sword, and caught a Yamper (now a Boltund). I named him Wattson because of watts + Watson from John Watson from the Sherlock Holmes novels (because hounds are trackers like detectives was my thought process, lol). Hence, Wattson the Boltund ⚡️

Another in the same game are my Gardevoir named Guinevere and a Gallade named Lancelot. It just made sense.
