A pale, thin man with a hooked nose, Jax Pavan worked as a corrections officer at the Bedacus-Lambrecht Correctional Facility, known to the inmates and staff as "Bedlam." Being fresh out of the academy, with a pressed suit and shined shoes, Jax's naivete was an obvious problem and he was often the target of the inmates' transgressions. Every day, Jax was spit at, had unmentionable substances thrown at him, thoroughly cowed by prison gangs, and threatened with rape. It was not until after a riot did Jax discover that he was armed with a nightstick and was permitted to use it against the prisoners.
Thus, Jax Pavan bulked up and started beating unruly inmates into submission. He enjoyed his job and the feeling of power it granted him as he bashed kneecaps and knocked the teeth down the throats of prisoners stupid enough to give him lip. He became notorious as one of the toughest corrections officers in Bedlam.
Jax's reign of terror was not to last, however, as he had an extreme phobia of insects. When Zuckuss was incarcerated in Bedlam, his presence reduced Jax to his former naive self... until he started arming himself with a flyswatter and a can of bug spray. With his new arsenal, Jax returned to his overly-aggressive methods, freely breaking the faces of inmates.
