 Similar to General Zod and other Phantom Zone escapees, Jax-Ur generally never experiences the full measure of his abilities as he is never allowed to spend any significant portion of time beneath Earth's yellow sun to charge and metabolize his cells with yellow solar radiation before being banished back into the Zone.As such, should he ever be allowed enough time to fully realize his abilities and potential, Jax-Ur's power levels would very likely approach or possibly surpass those of Superman as he is a fully mature Kryptonian male with exceptional natural physical prowess and experience in combat.Like all Kryptonians, Jax-Ur is vulnerable to Kryptonite and red solar radiation which neutralizes and cancels out the yellow solar radiation flourishing in his cells.
