Hyakujuu Sentai Gaoranger: The Fire Mountain Roars(2001)

The six Gaoranger were fighting the Orgs as usual, but a strong impulse pulled them along with Tetomu into a rift in space-time. They arrived in Org Island, a volcanic island in another dimension that is ruled by the Orgs. To regain the island's freedom, the Gaorangers joined forces with the island's resistance to face off against the three Org Brothers.
