|This article is about a/an planet in Kaizoku Sentai Gokaiger.|
The unnamed Zangyack homeworld (ザンギャック本星 Zangyakku hon hoshi) is where the Space Empire Zangyack is based. It became the next destination of the Gokaigers several months after they defeated Emperor Ackdos Gill, crippled the Zangyack fleet from across the universe and stopped their invasion of Earth resulting in the dissolution of the empire. Having already acquired, discarded, and destroyed the first Greatest Treasure in the Universe, Captain Marvelous returned the Ranger Keys, along with the Great Powers within them, back to the past Sentai warriors. He and his crew departed the Earth, going on a journey to the homeworld of Zangyack to find what he presumes to be the second Greatest Treasure.
Upon arriving at the Zangyack homeworld, the Gokaigers were attacked by Zangyack. They faced Gokdos Gill, the embodiment of the will of every evil emperor in the cosmos, who proved to be a great challenge but was eventually defeated. Ultimately, however, the Gokaigers were overwhelmed by the Zangyack remnant led by the nephew of the late Ackdos - Bacchus Gill -, and were forced to pretend to serve them before teaming up with the Go-Busters. It has not been revealed if they found the Second Greatest Treasure afterwards.
