Suika

A Zeraora working a job as a search and rescue specialist. Despite the unusual coloring for a Zeraora, she does her job just fine, especially when battling more ferocious pokemon that abduct trainers like Froslass.
Suika doesn't really have a trainer or any real owner, she just sort of walked into their offices and wrote up a resume. She has above average intelligence for a pokemon, but doesn't speak words that humans can hear, mostly having a psychic-type give her words or she signs while saying "Zeraora" over and over. Due to her mythical status she's got immense power, with a round moveset including Plasma Fists, Electroweb, Protect and Reversal. Half the moveset is more for search and rescue rather than pure combat.
