Jax is a mischievous (occasionally flat-out bloodthirsty), laid-back, calm, sassy, impulsive, egotistical, arrogant, sarcastic, and brazenly condescending individual, and rarely shows any empathy or remorse for those around him. 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 Ragathaa 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."
