Jax is a mischievous, impulsive, rebellious, reckless, sarcastic, and brazenly condescending individual, and rarely shows any empathy or remorse for those around him (only cares about the thrill and fun). Jax appears to be a purple-colored cartoon rabbit whose's design evokes the look of early cartoon characters. He has long purple ears on top of his head, and his overall build is tall and slender. Jax has black eyes with square pupils, and his sclerae and teeth are both yellow.
