Jax is a tall and lanky periwinkle colored talking rabbit that stands on two legs that wears a pair of red overalls, yellow teeth and eyes adorning his face. He has a mischievous and sassy personality, rarely showing empathy for those around him. He used to be a human before he became trapped in the Digital Circus, but he appears indifferent about his situation and is not desperate to escape it. Jax loves pulling pranks and annoying others in the Digital Circus, including newcomers.
