Jax is a tall, anthropomorphic periwinkle[5] cartoon rabbit whose design elements evoke the look of rubberhose characters, despite having actual joints. He has long bunny ears on the top of his oval-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 that contract when angered and heavily dilate when at a loss for words. His eyes change into animated scribbles when he is stressed or anxious. Jax's yellow teeth usually have a flat shape to them, but when his mouth is opened, his teeth appear sharp and jagged. Almost every time he is talking, his teeth stay closed while only his lips move. Jax has thin black eyebrows that appear in the majority of scenes. In "They All Get Guns" and onwards, Jax has a small spherical tail which he didn't have before the episode, being mentioned briefly during Untitled when Jax is talking to Pomniwhile during the "Stargazing" segment. Jax wears light pink overalls and pale yellow gloves. His overalls feature yellow buttons, a single lighter pink pocket on the front, and lighter pink roll-up cuffs at the hem. He is usually barefoot. He is 22 years old. And he is 6’2 1/2ft tall. Personality Jax is a mischievous, occasionally flat-out bloodthirsty, laid-back, calm, sassy, impulsive, egotistical, arrogant, sarcastic, brazenly condescending individual who rarely shows any empathy or remorse for others. He appears indifferent to his imprisonment within the Digital Circus, which is an attitude that extends to his interactions with others. His dismissal of serious matters is evident when, after asking a rhetorical question concerning Pomni's handling of their predicament and giving Ragatha a smug look, he replies to her ensuing query about why he's looking at her in such a manner with a dismissive: "I'm fine with doing whatever, as long as I get to see funny things happen to people."Jax's lack of care for others is further emphasized when he steps on Gangle's already broken comedy mask, allow the Fudge Monster to eat the citizens of the Candy Canyon Kingdom, or when he abandons Pomni and Ragatha to abstracted Kaufmo.
