Chronosteel is a very strong substance in the world of Ninjago, with the power to absorb and strip Elemental Power from the Elemental Masters. It was used by Ray and Maya to forge the four Time Blades, allowing for Wu and Garmadon to strip Krux and Acronix's powers over Time. It was also used by Chen to make the Staff of Elements.
After the Serpentine War, Ray and Maya created the Time Blades out of Chronosteel in order to strip the traitorous Elemental Masters of Time of their powers. The plan succeeded and the blades were scattered into the future.
- Power Stripping - As performed by the Staff of Elements and the Time Blades that were forged from Chronosteel, it has the power to drain the power of the Elemental Master, rendering the Master a normal person. However, if the Chronosteel is destroyed, any elements stolen by it will return to their original masters.
- The prefix "Chrono-" means time, indicating the use of Chronosteel to take Acronix and Krux's Time powers.
