Like all Saiyans from Universe 7, Leek possesses a tail and has jet black hair which is a common trait among Saiyans. He also wears Frieza Force clothing and possesses a scar in the left side of his forehead. Leek received this from Flayk during the attack on Planet Cereal. His hair is also noticeably short and he possesses a leg band wrapped around his right thigh. Leek is laid back and relaxed, but possibly forgetful, as he had left his scouter on while insulting Frieza. He is friendly towards Bardock, but dismissive of his theory that Frieza would kill the Saiyan race.
