Episode Title:
The Hands of Time.
Episode Description:
At the ruins of the Monastery of Spinjitzu, a strange vortex opens up to admit a mysterious hooded warrior who is then confronted by Master Wu; the pair recognize each other and Wu reveals that it has been forty years since he last encountered his enemy. Elsewhere, Misako is unloading supplies at the Temple of Airjitzu with the assistance of Ronin and the of Dareth, while the Ninja are helping Dr. Saunders at the museum. While there, Kai and Nya find a portrait of their long-missing parents, Ray and Maya, and the Ninja also discover a portrait of a battle between Wu and Garmadon and the "mythical" Hands of Time, Acronix and Krux. Acronix, who happens to be Wu's mysterious enemy, is defeated but then restarts the battle after a Time Blade emerges from the vortex, causing a temporal wave that draws the Ninja to the monastery after Acronix strikes Wu with the weapon. During the ensuing battle, Acronix reveals that he knew Kai and Nya's father and then escapes after faking his own demise. He then meets up with Dr. Saunders, who is revealed to be none other than Krux.
