"Metal Alice, do it now!"
―Robogog of the 10-sai's first words after Metal Alice told him that the creation of Zan-KT of the Shield was near completion.[src]

"This will not stand, Gosei Angels! I'll grind every one of you into dust!"
―Robogog when he grew.[src]

"BladeRUN! I knew it, you're... "
―Robogog's final words before he was killed by Buredo-RUN of the Cyborg.[src]

Robogog of the 10-sai (10(テン)サイのロボゴーグ Tensai no Robogōgu) was the leader of the Matrintis Empire and a major antagonist in Tensou Sentai Goseiger.



Robogog prior to his conversion as a cyborg

Robogog was originally a human scientist who perfected a method of immortality through cybernetics. Though ostracized for his methods prior to converting himself into a cyborg, the Matrintians begged for his help when their city sank into the sea. Given he was the only one still alive, he obviously did not save them and instead created his own race of robots, the Matroids, to form the Matrintis Empire.


After the fall of the Earth Condemnation Group Yuumajuu, Robogog and his second in command Metal Alice of the Agent build Zan-KT of the Shield to combat the Goseigers, having learned all he could from them so far. When Zan-KT fails, he and Metal Alice make their appearance known to introduce Metal Alice's own version of the Bibi Bugs whose hive sunk to the same body of water the Machine Fortress Terminel is located in: Bibi Nails. After they are used to enlarge the Matroid, they take their leave. Tvicon.png TV STORY-Epic 33: The Dreadful Matrintis Empire

Robogog continues to use his creations to gather intel on the Goseigers while adding Brajira of the Cyborg to his ranks to function as his trump card. He launches Buredo-RUN against his foes after losing complete respect for Metal Alice after her last failure.

Robogog reduced to a head

After getting enough info on his enemies, Robogōg makes his move to finish them off by using Buredo-RUN as a sacrifice to seal the Tensouders and the Leon Cellular. However, the Leon Cellular is still functional as Gosei Knight ruins his scheme to kill the Gosei Angels easily. Tormenting Buredo-Run for the failure he decides to use him as a suicide bomber only for Metal Alice to take the fall instead; something he can care less about.

Whilst he tells the story about his past human life in third person, the Goseigers are furious with Robogog for his lack of care for his subordinates as they defeat him with the Super Sky-Land-Sea-Knight Dynamic. After enlarging himself with the Bibi Nails, the Gosiegers face him in their mecha while Gosei Red, realising he was talking about himself in his story, tries to offer him a more peaceful way. Refusing to accept his chance of redemption, he tries to use his self-destruct attack to wipe out the Goseigers and possibly all of Japan as punishment for it, but is stopped by Datas Hyper and Gosei Ground before being scrapped by Ultimate Gosei Great. However his head survives, taunting the Gosei Angels that he can easily rebuild himself with his Salvation Cell. However, Buredo-RUN destroys the item instead of helping his regeneration and Robogog realizes Buredo-RUN regained his memories with Metal Alice's help, having purposefully allowed the Leon Cellular to work. Confirming his killer's true nature, Robogog's head is thrown into the air and obliterated by Buredo-RUN's missiles. Tvicon.png TV STORY-Epic 44: The Ultimate Final Battle

Robogog's spirit later appears to Brajira to stop his from destroying the Earth with the Nega End alongside Mons Drake and Kinggon but they are cast away. Tvicon.png TV STORY-Epic 49: Fight Towards the Future

Robogog is mysteriously revived in Kaizoku Sentai Gokaiger vs. Uchuu Keiji Gavan imprisoned inside the Maku Prison. He is sent by Makuu Prison Warden Ashurada to stop Captain Marvelous and Ahim from rescuing Space Sheriff Gavan from prison. They fight near the ocean but the fight is extremely brief as Ashurada quickly sends then to fight Kinggon. Robogog's fate is ultimate unknown but he is presumed killed once again when the GokaiGalleon Buster's Special Charge destroyed the Makuu Prison.


Robogog was a cruel, bloodthirsty, aggressive, heartless, and merciless man who believed that humans should be his slaves and ruled through fear. He initially respected his attendant Metal but, following her personal defeat, he lost that respect and dubbed her a low-spec Matroid and installed a Punishment Bomb on her and seized every opportunity to use it on her. His past experiences with humanity made him view all humans with contempt, even choosing to destroy himself along with the Goseigers after they reminded him of his past as a human. His belief of rule through fear, however lead to his downfall as his constant abuse of Metal Alice lead to her plotting with Buredo-RUN against him. His mistreatment of his subordinates made him different from the previous two villain leaders. Mons Drake and Makuin, who at least treated their members with respect.
