Dark Headders are monstrous familiars of Brajira. They are fusions of mythological beasts and are each named after a fantasy film series, with hyphens to divide the heads' individual names.
The two-faced Namono-Gatari of the Ortaurus Headder is the first of the Dark Headders to be used by Brajira against the Goseigers. Other than teamwork among his heads, the right-head Namono and the left-head Gatri, Namono-Gatari can regenerate his horns unless both are cut off at the same time, which the Landick siblings exploited before defeating the Dark Headder. Enlarged by the Bibi Bugs, Namono-Gatari allows himself to be destroyed by Landick Gosei Great so he can become the Land Wedge in the Nega End ceremony.
The triple-headed Bari-Boru-Dara of the Uniberus Headder is created by Brajira with the ability to turn into a right hand gauntlet, his main head is Bari, his right head is Boru, and his left head is named Dara. After being hit by the Super Sky-Land Dynamic attack and enlarged by the Bibi Bugs, he allows himself to be destroyed by Seaick Gosei Great so he can become the Sea Wedge in the Nega End ceremony.
The four-headed Ro-O-Zo-Ri of the Hydrapan Headder is created by Brajira with the ability to turn into a left hand drill gauntlet. His main head named Ro, his right head named O, his left head named Zu, and his blue-eyed head named Ri. In battle, he can shoot his drill arm blades and shoot green beams from his eyes. Enlarged by the Bibi Bugs, Ro-O-Zo-Ri is later destroyed by the combination of Datas Hyper and Gosei Ultimate and allows himself to become the Sky Wedge in the Nega End ceremony. He is later revived in the Super Hero Taisen movie series.
