Pomni is a morbidly obese stylized humanoid character, with a large head, chunky limbs, and an overhanging belly. She has completely white skin, with small markings imitating blush underneath her eyes. She wears a red and blue jumpsuit that barley fits with round, poofy sleeves, and shorts. In her initial appearance, Pomni is shown to have a degree of both empathy and selfishness.
