Jax

He has also demonstrated a predilection for bloodshed, combat, death, and chaos, as seen in episode 2 when he is deeply disappointed by the lack of all of the above, before quickly rejoicing upon realizing that Fudge had come to destroy the Candy Canyon Kingdom and its inhabitants—an act he himself provoked by leaving the entrance unlocked, which brought him no benefit beyond his own happiness, as the adventure was already over. Furthermore, he shows very little regard for the well-being of his fellow captives. He did save Gangle and Kinger from Kaufmo's abstract form, hiding them both with the bowling ball before jumping with them into the Gloink Hole, demonstrating that he does care for others, but masks it with his cruelty. It's hinted that Jax is insecure about showing vulnerability to others; despite briefly feeling sad, he refuses to attend Kaufmo's funeral. It's also worth noting that in episode 6, at the Favorite Character Awards, Jax briefly became excited about the fight with Pomni. Later, he went into the bathroom and began to have a panic attack, but upon emerging, his face was cheerful, suggesting a deeper facade to his personality. When Gangle is about to "re-evaluate" him, his first concern is whether anyone else might see him that way. Similarly, despite being completely exhausted from his day at Spudsy's, he refused to stop smiling in front of others and only let his tiredness show when he was outside and alone. Jax dislikes being ridiculed, as evidenced when he's dressed in a maid outfit, quickly becoming enraged with Gangle for changing his clothes, and then panicking excessively when Kinger sends him onto the baseball field full of NPC spectators.

Jax could be described as inherently selfish, only driven to act against the Gloinks when they begin to annoy him. Even when the Gloink Queen accuses him of continuing to observe events despite finding them "foolish and strange," he responds by saying, "I'm just here to hide from..." only to be interrupted by an engrossed Kaufmo who abruptly bursts into the Gloink Queen's lair; his utterance could hint at a singular concern for his well-being. He was also the only one of the captives who failed to attend Kaufmo's funeral; however, he is briefly shown to be saddened by this before quickly reverting to his normal demeanor, demonstrating that, to some extent, he does care for his friends and that his apparent indifference is merely a facade to avoid forming bonds. Furthermore, while he often uses insulting nicknames for his "friends," he used a much more positive "Kaufy" when referring to the abstract clown and apparently lent him a bowling ball, implying that he may have had a closer relationship with Kaufmo than with the others.

Jax used to be human in the real world under a different name. It's clear he doesn't have fond memories of his past life, as he becomes distressed when he thinks about it.

Shortly after, one day he entered the Circus after putting on virtual reality goggles. He befriended Ribbit and Kaufmo, other members of the circus, but for some reason, they drifted apart. This significantly affected Jax, causing him to become resentful and bitter towards the other members, and at one point he began to bully Gangle and had a strained relationship with Zooble.

Jax is a mischievous, sometimes downright bloodthirsty, laid-back, easygoing, cheeky, impulsive, egocentric, arrogant, sarcastic, and blatantly condescending individual who rarely shows empathy or remorse for those around him. He seems indifferent to his imprisonment in the Digital Circus, an attitude that extends to his interactions with others. His disdain for serious matters is evident when, after asking a rhetorical question about how Pomni is handling her situation and giving Ragatha a smug look, he responds to her question about why he's looking at her that way with a dismissive, "I don't care, as long as I get to see funny things happen to people."

Jax's indifference towards others is further emphasized when he steps on Gangle's already broken comic mask, allows the Fudge Monster to devour the inhabitants of Candy Canyon Kingdom, or abandons Pomni and Ragatha to the mercy of the abstract Kaufmo. He cares little to nothing for the opinions of others, and the group's consensus is of no concern to him. Instead of authentically interacting with others, he seems to participate in the Digital Circus's general activities simply for amusement, which makes him somewhat of a jokester. Zooble adds that during the adventures, "Jax just likes to mess with everyone" to highlight how troublesome he is. Despite these occasional outbursts of impulsive and reckless behavior, such as tearing down a "Spare" sign for no reason, he generally maintains a calm and collected demeanor, though his compliments are often insecure and frequently border on outright insult.

Jax is a tall, anthropomorphic, periwinkle-colored cartoon rabbit [5] whose design elements evoke the appearance of rubber characters, despite having real joints. He has long rabbit ears atop his oval head, and his overall build is tall and slender, with a fairly long neck. Jax's eyes have yellow sclera, with square black pupils that contract when he is angry and dilate greatly when he is at a loss for words. Additionally, his eyes become animated scribbles when he is stressed or anxious. Jax's yellow teeth are usually flat, but when he opens his mouth, they appear sharp and jagged. Almost every time he speaks, his teeth remain closed while only his lips move. Jax has thin, black eyebrows that appear in most scenes. In "They All Get Guns" and later, Jax has a small spherical tail that he did not have before the episode, briefly mentioned during Untitled when Jax is talking to Pomni during the "Stargazing" segment.
