Seeing Pokemon act as Trainers (even if ex-human) can be an odd sight...but as Eevee Kylee says, no rule against it! (If anything, they're more accommodating!) Commissioned lineart done by @chimetimes.bsky.social! Colors and background were done by myself.

An illustration of Kylee Howard, a Pokemon Trainer transformed from a human into an Eevee. She looks different from other Eevee in that her sclera is purple-blue like her eye color, her tail is larger, she has long, blue human hair, and her body's proportions are more grown-up like some of the Eeveelutions to match her adult age. She is also wearing a black/red/white Trainer's outfit with a visor, fingerless gloves, a shirt, and a bag for her items. She is sitting in a plain grassy area with a gray concrete path as she lifts her front right leg up to grasp her visor's bill. She winks at the viewer with a smile as she says, "What? There's no rule saying Pokemon Trainers aren't allowed to have big, fluffy tails, hehe!" In the bottom left is credit of the lineart to chime (@chimetimes.bsky,social) while colors and the background were done by me.
