Jax is a mischievous, laid-back, calm, sassy, impulsive, egotistical, and brazenly condescending individual, and rarely shows any empathy or remorse for those around him.
His overalls have yellow buttons on them and also has a single rectangular pocket on the front.
Jax wears light pink-colored overalls and yellow gloves. Jax's yellow teeth usually have a flat shape to them, but when his mouth is opened, his teeth appear sharp and jagged (or if taken context of that scene, it also can be a one-time thing purely made for comedic purposes.) Jax's eyes have yellow sclera, with square black pupils. He has long purple ears on top of his head, and his overall build is tall and slender. Jax appears to be a purple-colored cartoon rabbit whose design evokes the look of early cartoon characters, also known as 'rubber hose' characters.
