The four-headed Ro-O-Zo-Ri 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 named after The Lord of the Rings film trilogy and is modeled after the Lernaean Hydra, Pan, and a drill.
