Evil Spirits
There are three sets of antagonists, collectively referred to as the Evil Spirits (Ashiki Tamashii). Though all three have different origins and background, the groups use the Bibi Soldiers and Bibi Bugs provided by Brajira, who poses as a member of each group in a different form depending on the group. Brajira of the Messiah is the series antagonist and final enemy, a mysterious Gosei Angel who turned evil and faced the Goseigers as Warstar's Buredoran of the Comet before joining the Yuumajuu as Buredoran of the Chupacabra and then later drafted into Matrintis as Buredo-RUN of the Cyborg.

Brajira of the Messiah
Height: 199cm to 50.7m
Weight: 124kg to 317t
Brajira was originally one of the most powerful Gosei Angels, able to use all 3 elements at once after killing his teammates. After sealing the Yuumajuu leaders Makuin and Kinggon while incognito, Brajira became obsessed with his mission as a Gosei Angel to the point of creating the Earth Salvation Plan, which would allow him to destroy the world and remake it in his own image as its Messiah. To that end, after the other Gosei Angels refuse to aid him, Brajira used the Time Travel Tensou Technique to travel from his time into the present, losing his humanity in the process as Warstar arrives to Earth. From there, Brajira joins Warstar and gained the Bibi and the enlarging Bibi Bugs, providing his knowledge on the Gosei Angels so Warstar could do his dirty work in disabling them before he disposes of the aliens personally.

After Warstar's defeat by the Goseigers, Buredoran returns to the Yuumajuu after unsealing its leaders to have them finish off the Goseigers. When he acts on his own to control the Abare Headder before the Goseigers win it over, Buredoran attempts to do away with both the Yuumajuu leaders and the Goseigers. The plan backfires, and he is defeated by Ground Gosei Great. His lifeless body is then discovered by Matrintis Empire's Metal-Alice, and he is rebuilt as Buredo-RUN with his memories erased, as Robogogu knew his true identity and intended to use his ability to seal the Tensouders. However, Buredo-RUN regains his memory and sets up their downfall.

Taking control of the Terminel, renaming it Labyrindel, Brajira reveals his true form and captures Gosei Knight to make him his servant once more. Once revealing his true form, Brajira uses his personal Gosei Headders, the Dark Headders, to fight the Goseigers while enacting his Earth Salvation Plan. Furthermore, using the military might of Warstar, the magic of the Yuumajuu, and the advanced technology of the Matrintis Empire, Brajira begins setting up his master plan to set up the Nega End ceremony by having his Dark Headders be destroyed so they can become wedges in key points to start the process during a solar eclipse. After destroying Labyrindel in an attempt to get rid of Gosei Knight, Brajira is defeated by the Goseigers. He reveals that it is his own death that begins the Nega End. However, the Nega End is stopped by the Goseigers' Gosei Global technique.

In the film Goseiger vs. Shinkenger:, Brajira joins the Gedoushu and assumes a form similar to Doukoku known as Buredoran of the Bloodbath. In this form, Buredoran uses his Bibi Bugs to turn Shinken Red into his follower.

Brajira uses a perverted form of Gosei Power called Dark Gosei Power sealed away in special Orbs. By having an Orb enter his chest armor, Brajira can perform an ancient version of the Tensou Techniques, his being more crude compared to present Tensou Techniques used by the Goseigers and Gosei Knight. He also has used the Tensou Technique Timetrouble, an incomplete Tensou Technique that sent him to the future while mutating him by accident. Brajira has also mastered the forbidden Tensou Technnique End, that allows the user to bring life back to all creatures on the planet, using it as the basis for Nega End which has the opposite effect and thus cause a mass extinction.
