Digi-Ninja Quest is a four-part episode of the third season of Digimon Mighty Squadron. This content is used from the Power Rangers wiki.
In this episode, the DigiDestined teens win a volleyball tournament. SkullSatamon, brother of Lilithmon, lands on the moon with Karatenmon eggs & a Myotismon egg. SkullSatamon turns gigantic & challenges the DigiDestined, who summon ThunderOmnimon & WhiteTigerVespamon. At first the DigiDestined seem to have the upper hand, until four of Tactimon's old Digimon (who are now more powerful than before) arrive as part of a trap. ThunderOmnimon & WhiteTigerVespamon get badly damaged & start to malfunction. At the Command Center, Kokuwamon tries desperately to give extra power to the Digimon, but the DigiGrid overloads. The DigiDestined watch helplessly as ThunderOmnimon & WhiteTigerVespamon explode & vanish into their nothingness. As a result, the original Dinosaur Digimon are destroyed too & the digivices are damaged beyond use.
The DigiDestined return to the Command Center to learn that the digivices were created by a legendary being called Shurimon. The DigiDestined decide to search the treacherous Desert of Despair to find him. The bad guys learn that the DigiDestined are going after the Digi-Ninja powers & send the newly hatched Karatenmon to deal with them. The DigiDestined run from the bird Digimon to a long cave with a dead end. They learn that the cave's walls dematerialize as part two ends showing all six DigiDestined going through.
The DigiDestined find themselves in a garden after passing through the cave walls. There, they find giant gates leading into a temple. The DigiDestined enter the gate. Inside the Temple, the DigiDestined find Shurimon. The DigiDestined tell Shurimon of the destruction of their Digimon by SkullSatamon. Shurimon tests their virtue; after proving that the DigiDestined are good - not evil - he gives them their new powers & Digimon. The DigiDestined use their new Digi-Ninja powers to defeat the Karatenmon still waiting outside the Temple. They use their new Ninja DigiMemories to summon their new Digimon, & teleport to Tokyo in order to use their new Ninja Digimon against SkullSatamon. Meanwhile, the Myotismon egg is hatching in front of the Temple Gates...
The DigiDestined defeat SkullSatamon with "NinjaOmnimon + Aquilamon". Meanwhile, Shurimon has his hands full at the temple battling Myotismon that hatched from the egg. The DigiDestined show up just in time & together, they destroy Myotismon. Shurimon later says that he will help the DigiDestined whenever they need it.
