Juju is one of Space Empire Zangyack's Action Commanders.
He was voiced by Hideaki Kusaka.
He is also known as the "Devilish Witch Doctor", Juju can use a special crystal to intensify the darkness in peoples' hearts to the point of madness and was personally picked out by Insarn for a mission.
Among his victims were Doc and Gai, though Ahim manages to snap them out of the spell as the others confront him and attempted to destroy the crystal ball before he swallows it to keep his spell in check. However, with Ninjaman's help, the Gokaigers destroy Juju and restore everyone to normal.
An enlarged Juju is then destroyed by Kanzen GokaiOh's Gokai Kanzen Burst with the aid of an enlarged Ninjaman.
