Time Blades The Time Blades are four blades from the " Ninjago " theme , specifically the season seven story arc Hands of Time and its associated toys ; as their name implies , they are four blades that each have a different power over the element of time . History . The powers of the Time Blades originally belonged to Acronix and Krux , the Elemental Masters of Time who turned against their comrades . In order to defeat them , the other Elemental Masters had the blades forged by Ray and Maya from Chronosteel , a unique metal with the ability to absorb Elemental energy to the point of removing the powers of an Elemental Master . Wu and Garmadon then wielded these blades in battle against the Hands of Time and were able to drain their powers , with each blade gaining a different ability . Wu and Garmadon then used the blades to open a vortex so as to scatter the Time Blades across the ages , as it was felt that no one should possess power over Time again . The blades were then hurled into the vortex but pursued by Acronix and Krux ; Acronix ended up being sent forward forty years into the future , while Krux vanished but somehow managed to return and live in Ninjago under the assumed identity of Dr . Saunders . The green Fast Forward Time Blade possessed the ability to cause Time to move forward more quickly . It returned to Ninjago shortly after Acronix did , and unleashed a wave of energy that skipped time forward one minute ; Acronix then seized the blade and used it to continue his battle with Wu . After using it to defeat Wu with his " Time Punch " , which caused Wu ' s aging process to begin accelerating rapidly , he employed it in a brief battle with the Ninja before using it to escape , creating the illusion of his own demise in the process . Acronix would subsequently use the blade to ambush Zane in order to kidnap Cyrus Borg and to effect his and Krux ' s escape from Kai and Nya with Borg in tow . It was briefly taken from Acronix by Lloyd but reclaimed by General Machia ; Acronix would later use it to strike Ray with a Time Punch as well before placing it in the Iron Doom . The blue Slow - Mo Time Blade has the power to make Time move more slowly . It emerged from the vortex some time after Acronix and Krux unleashed their Vermillion army upon Ninjago , and the Hands of Time quickly directed their forces to recover it . They succeeded , but soon lost the blade to the ninja due to the efforts of Jay , only to recover it during their attack on the Temple of Airjitzu . After using it a number of times in battle , the Time Twins would place it in the Iron Doom with the other blades , enabling them to use the machine to travel through time . The red Pause Time Blade has the ability to freeze Time , and was the last blade to return to Ninjago . Acronix and Krux homed in on its arrival point using Acronix ' s BorgWatch , which possessed a temporal scanner ; their success made Borg regret adding that feature . They would subsequently use it against Ray and then against his family and Wu , the latter occasion preceding them leaving the five to fall into the Boiling Sea . Acronix and Krux also used it to stop Cyrus Borg , Samurai X , and Zane from causing the Iron Doom to self - destruct , before placing the blade within the mech so as to travel back in time . It would later be lost along with the Fast Forward and Slow - Mo Time Blades when the Iron Doom was cast adrift in time with Acronix , Krux , the Vermillion snakes , and Wu aboard . The orange Reversal Time Blade has the ability to cause Time to move backwards . It was the first blade to return to Ninjago , emerging unnoticed with Krux from the Temporal Vortex , and was found by Ray and Maya and hidden in the library of Hono Mizu in the Boiling Sea . However , the Time Twins later forced Kai and Nya to retrieve it , as it was the only means by which they could reverse Wu ' s aging process and save his life ; later it would also become essential to saving Ray as well . Having been added to the Iron Doom , it completed the mech ' s power to travel through time , but attempts to remove it initially proved fruitless . Fortunately , their presence in the past allowed Nya to make use of the past Reversal Blade - which hadn ' t yet been hidden - to heal Wu and enable the present heroes to pursue the Time Twins , leaving the blade with the younger Wu to preserve history . The old Wu would then succeed in removing the blade from Iron Doom and gave it to Kai and Nya to heal their father ; after they did so , Lloyd determined that the ninja would dispose of the blade .
