Master Urshifu (Patreon)

He's gruff, and as instructors go, he lacks all manner of decorum with his potential students. But then again, he doesn't really want to train anyone. Still, if you can prove your strength, tenacity and, well, maybe show him some skills he can't perform on himself... Master Urshifu might just consider taking you under his loinclo-- I mean wing!

[Been using this dude in Pokemon Unite and he's super fun. Never bothered getting the Sword/Shield dlc so this is actually my first time getting to play with him and dang, he is every bit the bara bait the internet's been telling me, lol.]
