Ten millennia ago, Brajira was an incredibly powerful Gosei Angel who fought against the Yuumajuu and eventually sealed away their leaders Makuin and Kinggon. However, after the, Brajira soon became obsessed with his mission as a Gosei Angel, leading to him devouring his teammates so he could use all three elements at once after killing his teammates to take their powers for his and devising the Earth Salvation Plan, a plot to kill all life on Earth so Brajira could remake it as his own.
When the other Gosei Angels refused to aid him in his plan, Brajira used the Time Travel Tensou Technique to travel into what he viewed as the future to enact his plan.
As Buredoran of the Comet
Guising himself as Buredoran of the Comet, Brajira allied with the Warstar armada to destroy the Gosei Angels. However, Buredoran was simply using Warstar to further his own plot, planning on disposing of them once they served their purpose. Brajira won his way into Mons Drake's ranks by providing to the Bibi Bugs.
The fallen angel eventually discovered that five trainee Gosei Angels were on Earth and had become the Goseigers. Following, GoseiRed's final battle with Dereputa, Buredorun noticed that the prison of Makuin and Kinggon had resurfaced.
As Buredoran of the Chupacabra
Brajira then released the monsters he had once sealed away and shifted his identity to Buredoran of the Chupacabra, claiming to be a Yuumajuu who had escaped imprisonment. As with the Warstar, Brajira was only using Makuin and Kinggon to defeat the Goseiges. However, both the Yuumajuu and Buredorun are defeated by the Goseigers and Gosei Knight.
As Buredoran of the Chimatsuri
Following the deaths of the Yuumajuu, Buredorun reemerged disguised as an Ayakashi named Buredoran of Chimatsuri. Claiming to be the descendant of Doukoku Chimatsuri, Brajira was able to obtain the assistance of Shitari of the Bones and the other Gedoshu. Buredoran attempted to take control of Shinken Red and use his fire Modikara to move the Sanzu Rivers' waters into the Gosei World through a portal that opens every two centuries. However, the plan failed with Buredorun being struck down by Ground Hyper Gosei Great.
As Buredo-RUN of the CyborgBuredoran's body was recovered by Metal-Alice of the Matrintis Empire who delivered him to Robogog, the leader of the Matrintis. Robogog rebuilt Buredo-RUN of the Cyborg and, knowing of Buredoran's true identity, opted to erase Buredoran's memories save for his name and hatred of the Goseigers to ensure his permanent loyalty. However, Metal-Alice eventually took pity on Buredo-RUN and gave him back his memory. After Robogog was defeated, Buredo-RUN destroyed Robogog's Salvation Cell switch and revealed that he had regained his memories. Buredo-RUN then criticized Robogog, calling the Matrintis Empire a "foolish ex-human illusion" before throwing Robogog's head up in the air and destroying it with missiles. Buredo-RUN then finished off Metal-Alice before exiting the scene.
Brajira reveals himself
Brajira then took control of the Matrintis's Terminel fortress and renamed it Labyrindel. He eventually revealed his true form to Goseigers, a fallen Gosei Angel. He brainwashed Gosei Knight into being his servant, but Gosei Knight broke free of his control.
Brajira then began the final preparations for his plan. After the wedge and the sky were set up, Brajira was visited by the spirits of Mons Drake, Makuin, Kinggon and Robogog. Brajira mocked the spirits for trusting him before casting them away. Gosei Knight then attempted to attack Brajira, prompting the fallen angel to blow up Labyrindel to try and get rid of him.
Brajira then fought the Goseigers for a final time. The Goseigers managed to fatally wound him, but that didn't stop him from using the last of his powers to set in motion the Nega End. Unfortunately for Brajira, the Goseigers were able to stop the Nega End with their Gosei Global technique, foiling his plans once and for all.
