With the drastic damages to their Power Coins caused by Rito Revolto, the Power Rangers headed into the Desert of Despair where they found Ninjor. Though he refused to help them at first since he thought they didn't have good intentions, after they said that they would fight anyways, he was convinced that they were sincere. Ninjor gave them Power Coins with new Ninja Powers and the Ninjazords and he later helped the rangers in their battles. However he was captured by Lord Zedd and Rita Repulsa after they discovered the Shogunzords so that they could use him as a power source for them. Ninjor later managed to escape them after Rito dropped the jar they kept him in when Master Vile arrived. But he was captured again by Vile after his new Blue Globbor monster absorbed energy from him. This also made it so the rangers wouldn't fight the monster, since hitting the monster hurt Ninjor as well. Luckily the Globbor monster lost some of its power, severing its link to the ninja master. He escaped and fought the monster and Vile alongside the rangers and their Megazords. However when Master Vile turned back time with the Orb of Doom, Ninjor ended up back in the temple where the rangers had found him.
PowersNinjor has a number of powers being a master of ninja powers, such as a white cloud he rides into battle on and the ability to disappear in puffs of smoke. He can also grow to the size of a Megazord (a form he calls Ninjor Expansion Mode) and enter a samurai esque fighting form called Ninjor Battle Mode, that allows him to fire explosive fireballs. Ninjor usually wields a katana in combat, but in Battle Mode, he combines it with the sheath to form a lance weapon.
- It is possible that Ninjor passed some information on how to create Power Coins to Zordon since when he created the new White Ranger, he had a new Tiger Power Coin for him that he most likely created.
- There is a minor plot hole regarding Ninjor. Zordon said that Ninjor and his temple was integral to maintaining the rangers' ninja powers and if either were lost, all would be lost. But even when Ninjor was kidnapped and imprisoned by Zedd and Rita, the rangers' powers were fine. (They did lose control of the Ninjazords but that was due to the Falconzord being stolen not Ninjor).
- Ninjor's counterpart in the Super Sentai series that the third season of Mighty Morphin Power Rangers was based on, Ninja Sentai Kakuranger, is Ninjaman.
