This article is about a/an villain in Hikari Sentai Maskman.

Earth Imperial Ninja Oyobu (地帝忍オヨブー Chiteinin Oyobū) is ninja of the Buyon tribe with red skin and large ears. He can throw fire from his hands and run at near-lightspeed. Being extremely loyal, he is Baraba's right-hand.


As a ninja of the underground, Oyobu held unquestionable loyalty to those who give him orders, particularly to his superior Earth Imperial Commander Baraba. Oyobu usually fought in the place of Baraba during the battles with the Maskman and accomplished any mission that was laid out for him without trouble. Many times he would head out on his own to watch the Maskmen, while using his abilities including a great speed that he could use to keep up with a moving car.Ep. 32: Oyobu's Lethal Dash

After Earth Imperial Commander Baraba became nearly expelled from Tube for his failures, Oyobu joined with him as he sided with Thief Knight Kiros in a scheme to steal the frozen corpse of Princess Ial. However during the siege, a flow of ice fell down on top of him freezing him completely solid like Ial even as Baraba and Kiros escaped with the princess. But unlike anyone else, Oyobu had his own means of escape, using up the energy of his life-force to create a powerful flame that burned and melted the ice away, making him the first being to escape from the frozen prison on his own. When Oyobu reaches Baraba after escaping from the ice, he tries to force him to fight Takeru for him, but the ninja for the first time refuses the request, stating that since Baraba had promised to Zeba on his own that he would stop the Maskmen, he had to fulfill his obligation by himself with no help from anyone. This statement ultimately leads to the commander's final battle and ultimately his death.Ep. 48: Baraba! Death by Treachery

After Kiros hears about Oyobu's means of escaping from the frozen ice prison with Ial still trapped within her block, he tries to force the ninja to use this ability to free Ial. After advising him about the consequences of using the special flame powers, the ninja instead attacks Kiros with the flame himself, starting a massive Tube assault that finally brought down the rebellious thief knight.Ep. 49: The Revived Princess Ial

With Baraba's death and Ial's ultimate rescue, Zeba decides to sacrifice his remaining forces in order to raise the Underground Castle and spread Evil Particles over the surface for his final scheme to create the darkness to rule the surface. Oyobu managed the controls for the final launch of the Underground Castle, dying within the chamber in order to make sure that the emperor completed his mission.Final Ep.: The Great Destruction of the Underground Empire Castle!
