jax appears to be a purple-colored cartoon rabbit whose design evokes the look of early cartoon characters, also known as "rubber hose" characters. He has long purple ears on top of his bean shaped head, and his overall build is tall and slender, with a rather long neck. Jax's eyes have yellow sclera, with square black pupils. Jax's yellow teeth usually have a flat shape to them, but when his mouth is opened, his teeth appear sharp and jagged.
