Based on a shiny Shinx I evolved from Pokemon GO.
Often a no-nonsense fighter with incredible electric power, she takes part in multiple battles and contests simply to hone her skills.
Outside, she is known to be pretty promiscuous, capable of having sex with anyone in range. Can be a reward for beating her in battle, or just on a whim, though that doesn't last forever.
Ever since an encounter with a Snorlax when she was young (kept her company when she got lost), she has a thing for chubby guys (not fat/slob-like) because of their personality and cuddliness. This is what led her to have a relationship with a plump Alolan Raichu, whom I'll reveal soon.
