Edit: Okay I have slept!! Proper description time!
This is Yaegwn Sawn, a 30yo rich pervert who pretends to be younger than she is so no one side-eyes her for still being on a Journey (spoiler alert: they do).
Her babies are Snowy the togekiss, Hein the raticate, Mephistopheles the magmar and Goya the golduck.
Snowy was given to her as her first pokemon, because her father thought that'd be an appropriate starter for a nice lil girl. But he's actually a terrifying murdermachine which is PERFECT for Yaegwn she uses him as her tank and for Fly.
Hein was the first pokemon she caught. He is a gross, lice-infested, disease-carrying vermin and they love eachother.
Mephistopheles was caught as a magmar. He was cock of the rock before Yaegwn showed up. She baited him into battle with the weaker Hein and then had Snowy sneak up and beat him into a bloody pulp. He's extremely arrogant in nature and his shame at being defeated by this sneering loser keeps him from just murdering his way to freedom. She only really lets him out for battles anyway.
Goya is the most recent member of the team and he's just??? Really disturbed at what's going on here no stop some one help him.
