It appears that Nightly has a neutral relationship to both the Jetters and the Hige-Hige, as at one point in the anime, he even brings Mujoe and Birdy together who were, at the time, enemies, to exchange information on each other's behalf and for each other's benefit about Max and Mighty, where Mujoe revealed that Mighty was killed. Nightly was supposedly killed in "Rebirth of the Dark Hige-Hige Bandits" when he was attacked by Max and nothing was left of him except his hat, but he was seen again in the final episode, where it is shown he survived, although sustaining an injury on hand.
