Having transcended their humanity, the Three God Generals aided the KakuRangers' ancestors in their fight with the Youkai.

However, tricked by Daimaoh into hurting humans on the notion that they were Youkai in disguise, Ninjaman gets sent into space within a Jar of Seals that only those of the Tsuruhime line can shatter. Once returning to Earth, Ninjaman is found by Junichi and his sister Mitsuko before the three find themselves attacked by the Youkai Bakuki under orders from Daimaoh to capture Ninjaman to become the Youkai leader's retainer. Luckily, once freed by Tsuruhime, Ninjaman becomes an ally to the Kakurangers. After Daimaoh's defeat, Ninjaman departs with his masters and says goodbye to the Kakurangers. However, this time resulting from not holding back, Ninjaman is sealed again for a few decades before being freed by the Gokaigers and helping them receive the Greater power of his Kakuranger friends.

As a ninja master, Ninjaman wields a katana, the Ninja Sword (ニンジャソード, Ninja Sōdo), and had a wide array of Ninja Arts at his command, including the "Art of Fire Escape", and size manipulation to aid his mentors and the Kakurangers in their fights. He can ride on a cloud called the Kintou Cloud. Whenever a Youkai calls him a "novice" (青二才, Ao Nisai), Ninjaman gets angry enough to change into his true form, Samuraiman (サムライマン, Samuraiman), by the command "Anger Explosion!!" (悪女爆烈, Ikari Bakuretsu). In this form, connecting his katana with its sheath to form the powerful Samurai Javelin (サムライジャベリン, Samurai Jaberin), Samuraiman creates explosive energy spheres formed from his rage in his ultimate attack, Samurai Rage Bomber (サムライ激怒ボンバー, Samurai Gekido Bonbā), or the Samurai Rage Slash (Samurai Gekido Giri) with the Samurai Javelin.

During the events of Kaizoku Sentai Gokaiger, Ninjaman was freed from a pot by the Gokaigers. Once freed, he decided to observe the Gokaigers to see if the team was worthy of the Greater Power of the Gokaigers.

But the Kakurangers refused to accept that and are quickly defeated before Sandayuu had Tsubasamaru bring them the Wind Illusion Castle to see the Sanshinshou, revealing their origins and that obtaining the Shinobi Scrolls are needed to stop Daimaoh. While Tsuruhime was looking for her Shinobi Scroll, she is found by Sandayuu and taken to her family's mansion. There, Sandayuu uses her quest as a test to prove her worth as the Kakurangers' leader and heir to her family legacy, providing her with karakuri replicas of her teammates.

In present day, Daimaou has his son Gashadokuro set up preparations for his coming into the human world by gathering children's souls to begin a ritual to resurrect him within a month's time. Though Super Kakure Daishogun destroyed it, the Seal Door reformed itself and Daimaou emerges, turning the altar into his base of operations.

After his 1,200th birthday, Daimaou gained the power to spawn clones of himself as he created Daradara to aid him in wiping out the Sanshinshou by putting them in a predicament through Daradara siphoning the powers of Ninjaman and four of the Kakurangers. However, due to Hakamenrou giving Ninja Red the means to ruin his scheme with Junior's manor destroyed in the process and managing to escape after being wounded by a combination of Super Muteki Shogun's Muteki Cannon Full Discharge and Super Kakure Daishogun's Iron Fist Flying Finish, Daimaou turns the human into stone before establishing himself in a new base of operations: The flying skull fortress Skull Castle (ガイコツ城, Gaikotsujō) with plans to build the Youkai Kingdom on Earth and destroy the Kakurangers.

He then made it personal for the Kakurangers by murdering Zashiki-warashi after failing to turn him evil. Though they almost got him during the trap he set up with Tsuchigumo, Junior escapes via a hot-air balloon. Junior eventually begins to carry out the ritual to summon his father Daimaoh back into the world, sending Umibozu to capture five children to begin the ritual and using his music to petrify the remaining ten to complete the ritual. As a result, Gashadokuro is infused with Daimaoh's power and is beyond the Kakurangers' ability to fight as he takes the skull-like altar he created on a building and the surrounding district into the sky beyond the Kakurangers' reach so Daimaoh's resurrection can be uninterrupted as he turn the humans trapped in the barrier to stone. While Gashadokuro appears to be completely heartless to even his lackeys and more relentless in combat, he does have some respect for the Kakuranger, as seen when he allowed his Dorodoros to give water to the Kappa-ized Seikai and Saizou to fight Nue.

Once all the Kakurangers had obtained the Shinobi Scrolls, Junior assumes his true form to battle the Chounin Beasts and stop them from destroying the Sealed Door. However, he is overpowered by them until Hakamenrou intervened. The fact that he had to be saved by the very human whom Daimaou prizes above him drove Junior to have Hakamenrou prove himself to him by killing the Kakurangers. But after mortally wounding Sandayuu when he aided Hakamenrou in saving the Kakurangers, Junior assumes his true form and overpowered the Kakurangers at first until Sasuke receives Hikarimaru to defeat Gashadokuro.

With this new gear, he gained an attack called "Crush Beam". But the tables turned when the team form Kakure Daishogun, and then Super Kakure Daishogun, stripping off his gear before killing him.

After enlarging to lure the Three God Generals out by destroying the city while subjecting people to his ooze, Daradara assumes an Asura-like form with the helmets of Ninja White, Yellow, Blue, and Black around his head and a variation of their attacks, such as the Black Bow and Kakuranger Ball. However, Daradara had a glaring weakness that Hakamenrou uncovered: That he and Daimaou are spiritually linked. With this knowledge, as the Youkai was fighting the Sanshinshou, Sasuke manages to wound Daimaou enough to force Daradara to cancel his siphoning and revert to his original state. From there, attempting to support Daimaou, Daradara is obliterated by Muteki Shogun and Samuraiman's Flaming Shogun Sword and Samurai Rage Bomber combo.
