Agni is a small, 2-foot tall fairy with glowing purple eyes, messy red-orange, hair, and ember-tipped antennae. He wears a flower headband with a bright purple flower near the front. He wears a oversized purple sweater with firefly patterns and some patchwork. His flame-like wings stick out from the back of them, giving off a fiery glow.
