Hebi is a snake-like Raytraxian, with indigo fur and a violet underbelly. Their eyes are bright yellow with a violet ring around it, with thin black pupils. It has a greenish-yellow tongue with light purple spots sprinkled around the mouth, a star-like marking on its forehead, and tiny black dots near their eyebrows. Hebi has gecko-like paws with sharp claws, and a long lizard tail. One of their more notable features, however, are the glowing white crystals covering their body (likely referencing the crystals in Crystal Cave during a Blackout event). They also have similarly white glowing claws on their hands.

Hebi is big muscular and buff and defined
