Time Twins

The Time Twins, also known as The Hands of Time, are a pair of villainous siblings, Acronix and Krux, who are allied with the Vermillion. They are the Elemental Masters of Time.

Abilities
The Time Twins have control of a powerful secondary element, Time. After Ray and Maya forged the Time Blades, and Wu with his older brother Garmadon used the blades to steal the power of the twins, thus causing them to lose their power. Before that, Acronix was able to speed up Time, which allowed him to disappear and reappear whenever and wherever he desired. He also was able to slow Time allowing him move away from the firing line. His brother, Krux, had the opposite power. He could rewind (reverse) Time against an opponent which allows him to see his opponent's next move and defeat his opponent before it happens. He also was able to stop Time completely. After their power was stolen they would later recover the Time Blades inorder to get their power back.

History
During the Serpentine War The Hands of Time fought alongside Wu and Garmadon and the Elemental Alliance to defeat the Anacondrai and Chen and Clouse. When they emerged victorious, the twins betrayed the alliance believing that their powers are stronger the they should rule Ninjago. Wu and Garmadon, along with the rest of the alliance wanted to stop them, but failed miserably against their temporal powers.When Ray and Maya forged the Time Blades to beat then, Wu and Garmadon succeeded in stealing their powers, and using it to create a temporal rift to banish the blades through space and time, so that no one can use it's power for evil.However, the twins didn't give up, they jumped into the Time void to follow their drained power which caused them to be lost in time. Immediately, after they jumped into the void when Krux emerged from it with the Reversal Time Blade, he succeeded in making an alliance with Ray and Maya by forcing them to work for him or else he'll kill their children. They then betrayed the brothers and the Elemental Masters to work on Krux's plan, with the incident becoming known by Chen as well in the process.
