Kim

Summary
Jackie's datemate. They both purchased a black shard from Quinn and both used it to mutate. Kim went first and lucked out, getting a really cool mutation, but Jackie got something kinda inconvenient.

Kim is bigender, and uses their mutated shape-shifting abilities to present as whatever gender they feel like at any given time. They can take on any human appearance but they can't perfectly imitate someone's form without reference material. Their form is somewhat fluid and their appearance can change over the course of the day without them noticing, too.
