**Krux** is one of the two current (and powerless) Elemental Masters of Time. He is the older twin brother of Acronix. Once a proud Elemental Master, Krux and his brother betrayed the Elemental Alliance due to them believing that their element was the strongest. In response, their former allies forged a set of weapons called the Time Blades that absorbed the twins' element. Krux and Acronix were lost in the temporal vortex, but Krux managed to escape.

For the next forty years, Krux conspired to strike back against Wu and Ninjago. As he awaited his brother's return, he bred an army of Vermillion snakes and took on an alias as a museum curator, **Dr. Sander Saunders**. He also kidnapped Ray and Maya so they could mold armor for the Vermillion, and build a time-traveling mech, the Iron Doom. When Acronix finally returned, Krux had Cyrus Borg captured so he could complete the Iron Doom's construction. With Wu out of the action, the ninja struggled to fight Krux, his brother, and their Serpentine army.

Ultimately, the Iron Doom was completed, and Krux traveled back in time to defeat the original Elemental Masters. Using their Fusion Dragon, Kai and Nya made a final effort to thwart his plans. When the Iron Doom traveled into the future, Wu removed the Reversal Time Blade from the weapon, and it was lost in the Time Vortex. Though Kai and Nya escaped, Krux was lost along with his brother and Wu. He and his brother’s fates are currently unknown.

## Biography

### Early life

Krux was born three minutes before Acronix. They were both descendants of the original Elemental Masters of Time. He and Acronix were raised by their mother, who claimed that Krux was stubborn.

#### Fighting in the Elemental Alliance

By the late 1970s, Krux and his brother Acronix were the era's Elemental Masters of Time. While Acronix could go forward in time and slow down time, Krux could go back in time and pause time completely. He used these powers to great advantage; going back in time seconds before an opponent could make a move and turning the battle in his favor and freeze someone in place.

Krux and Acronix fought alongside the Elemental Alliance in the Serpentine War. After the war, they were congradulated along with the other Elemental Masters at the Monastery of Spinjitzu.

#### Betraying the Alliance

To achieve some form of victory in his downfall, Master Chen had his right-hand man, Clouse, use his Dark Magic to manipulate Krux and Acronix into betraying the Elemental Alliance, and Chen informed the twins of the location of the Great Devourer's eggs.

Knowing that they were more powerful than the other Elemental Masters, the brothers decided to betray the alliance and use their powers to control all of Ninjago. The other Elemental Masters fought against Krux and Acronix, but the two proved too powerful. With the Time Blades forged by Ray and Maya, Wu and Garmadon fought a lengthy battle against the Time Twins at the monastery. Eventually, Wu and Garmadon used the Time Blades to absorb Krux and Acronix's elemental powers, rendering them normal men.

Knowing that the power to control time was dangerous, Wu and Garmadon used the Time Blades to open a vortex that would leave the Time Blades lost forever. However, Krux and Acronix decided to go through the vortex themselves, which left the two "lost to time."

#### Becoming the Curator of the Museum

While Acronix would be lost in the time vortex for forty years, Krux was somehow immediately teleported back to Ninjago, along with the Reversal Time Blade. Krux then changed his hairstyle, wore makeup to cover his tattoo, put on a fake long mustache and fake glasses, and disguised his voice so he could take on the false identity of Dr. Sander Saunders, working as the curator of the Ninjago Museum of History, while he secretly used eggs from the Great Devourer to breed an army. As the years went by, Krux had grown to hate modern life, especially technology.

Krux's army would need weapons and armor, and he knew exactly who could make them. Under the disguise of Dr. Saunders, Krux took his time to become a trusted friend of Ray and Maya. One day, Krux revealed his true identity to the Masters of Fire and Water, and threatened to harm Kai and Nya should they refused to do his bidding.

As Dr. Saunders, he would host school field trips at the museum, interacting with Nya, Jay, and Cole in their younger years.

### Wu's Vision

Falling asleep following his battle with Clouse, Wu would be stricken with a horrible nightmare of many visions of the future, most notably the return of Krux and Acronix.

### Hall of Villainy Exhibit

Not long before the Yin-Yang Eclipse, Krux, using his identity of Dr. Saunders, created several videos detailing the histories of villains the ninja faced in the past, to promote the Hall of Villainy exhibit at the museum.

As Dr. Saunders, he greeted the ninja when they arrived at the Ninjago Museum of History, with Kai being a little amused by his name before he gave them a tour of the new Hall of Villainy exhibit as well as showed them the Yin Blade. Later that night, Dr. Saunders was present on the Day of the Departed concert with Dareth. After Dareth defeated the resurrected Kozu and his Stone Warriors, Dr. Saunders expressed extreme displeasure at the damage to his museum caused by the conflict.

### Cleaning up the Museum

When the ninja were called to the museum to help clean up the damage from the night before, Dr. Saunders became hysterical when he realized that his thermostat had been destroyed. When the ninja questioned Dr. Saunders about why his thermostat was so important, he simply claimed that the museum needed to be kept at a certain temperature to preserve the exhibits.

After the ninja took back the BorgWatch prototype from Pythor, they used it to repair the original thermostat. Dr. Saunders was happy that his thermostat was working again, but expressed his dislike for modern technology. Zane then noticed an ancient-looking watch that Dr. Saunders kept in the museum, and Dr. Saunders said that he used the watch to tell time for many years. After the Ninja left, Dr. Saunders listened to the humming sound coming from the museum basement.

### Battle for All of Time

#### Acronix's Return

Still disguised as Dr. Saunders, Krux was in the Ninjago Museum of History and presented the ninja with refreshments after they helped clean up the museum, telling them it is pickled beet tea, causing them, except Jay to not drink them. The ninja questioned him about a painting that had both Wu and Garmadon in their younger years fighting two mysterious warriors at the Monastery of Spinjitzu. Dr. Saunders claimed that the painting was a myth, explaining that the Time Twins was merely a "folktale," explaining that they had the power to control time itself.

While looking at his watch sometime after the ninja left, he was confronted by Acronix. After taking off his mustache, he revealed that "Dr. Saunders" was just a disguise Krux took on before hugging his brother.

#### Setting His Plans in Motion

At his lair in the museum, Krux was extremely annoyed by his brother's growing fondness for the modern inventions that he never got to experience, such as TV, coffee machines, the BorgWatch, and the BorgPad, and Krux claimed that he despised modern life. Krux showed Acronix a helmet and said that he would return Ninjago to its "pre-modern glory," before revealing the Vermillion eggs.

Later, Krux unleashed a Vermillion warrior at the big unveiling of the BorgWatch; commanding it to destroy the Borg Store and to kidnap Cyrus Borg himself. When the ninja arrived, Krux unleashed two more Vermillion warriors. While the ninja fought off the Vermillion at the Borg Store, Zane and Borg fled the scene, only to be confronted by Krux in the disguise of Dr. Saunders. With Acronix by his side, the two kidnapped Borg and took him back to the museum.

Back at the museum, Acronix expressed his displeasure that they had lost most of their armor for the Vermillion in the battle against the ninja. However, Krux assured his brother that he already had his "best blacksmiths" working on more armor. Krux then revealed that he had released hundreds of Vermillion eggs into the swamps of Ninjago through the sewer beneath the city.

After locking Cyrus Borg in a Serpentine coffin, Acronix questioned Krux as to how they planned to control the growing force of Vermillion that they needed for "phase two" of their plan. Reminding his brother that he had 40 years to devise the plan, Krux then introduced Raggmunk, Blunck, and Machia; three Vermillion selected from the genetically superior of Serpentine who was thus able to control the other Vermillion warriors telepathically.

#### Confronting Kai

When Krux was informed by Raggmunk that Kai had entered the museum, he allowed Acronix to monitor the ninja through a telescope that he had built into a snake statue since he didn't install a security camera. Noticing that Kai had taken a Vermillion helmet, Acronix feared that the Ninja of Fire was onto their plan and insisted that he neutralize him. Knowing that it would draw too much attention, Krux declared that he would attend to the matter himself and ordered the Vermillion commanders to commence phase two of the plan.

Disguised as Dr. Saunders, Krux confronted Kai. When Kai asked if he recognized the Vermillion helmet, Dr. Saunders claimed that it resembled a post-Serpentine War samurai helmet, but was likely a knockoff. Kai explained that he obtained the helmet during the battle against the Vermillion that attacked the Borg Store and asked if Dr. Saunders had seen it on TV. This prompted Dr. Saunders to mutter under his breath that he despised TV, reverting to his normal voice of Krux for a brief moment. Kai eventually realized that the Vermillion helmet was identical to the helmets worn by Krux and Acronix in the painting. When Dr. Saunders tried to convince Kai that the Time Twins were still a myth, his fake mustache ended up tangled on the snake statue and fell off; revealing his true identity.

A lengthy battle between Krux and Kai ensured, during which Kai discovered that Krux had kidnapped Cyrus Borg and had likely taken Zane as well. As the battle continued, Krux claimed that Kai and Nya's parents were traitors who fought with the Time Twins. Due to Kai's anger, Krux briefly gained the upper hand when Acronix revealed himself and prepared to finish off the Ninja of Fire with the Forward Time Blade. However, Nya arrived and helped Kai in the continuing battle. Eventually, Krux was kicked into the same Serpentine coffin that Borg had previously been locked in, before Acronix used the Time Blade to make their escape.

#### Returning to the Lair

After the Vermillion hoarded all of the metal they could find in Ninjago City, Krux and Acronix led them through the sewers to their secret lair. When the Time Twins found themselves lost, Acronix pointed out his BorgWatch had built-in GPS. However, the BorgWatch was unable to function because there was no service, and Krux then gloated that this was one of many reasons why he refused to "get with the times." Krux then decided to follow his map, only to be led to a dead end.

#### Finding the Second Time Blade

At the Vermillion Swamps, Acronix entered Krux's room, telling him that everything is going to plan, including the construction of the snake mech, as well as their "labors" being hard at work on their various projects before asking how things were going with Borg. Krux informed him that it was going poorly, saying he has made little to no progress with the Time Apparatus. Borg then tried to make an excuse as to why, but Krux told him that in his time they built with anything they had and that craftsmanship meant something before accusing him of not wanting to make the apparatus. While Borg stated that they can't make him, Machia arrived, having began called to the base by Krux to "motivate" Borg. As Machia begins to torture Borg, Acronix slightly cowered behind Krux before telling him that he liked her because she's mean. Krux teasingly suggested that he had a crush on her, which Acronix rejected. While admitting she may be cute but deep down she is just a pile of snakes, time immediately slowed down briefly due to the arrival of the Slow-Mo Time Blade.

While Krux realised it has arrived, Acronix began to use his BorgWatch, which angers Krux. Acronix explained he was trying to use his BorgWatch to uncover the Blade's location, but his brother was distracting him. As Krux told him he puts too much faith in technology and that his smartwatch doesn't seem all that smart, Borgrevealed that the BorgWatch had things such as a heart rate monitor, a GPS unit, and a temporal anomaly locator, which Acronix used to locate the Blade at the coordinates 34 degrees latitude and 28 degrees longitude. Defeated, Krux reluctantly admitted that technology has its uses sometimes before Machia identified the coordinates as the Eastern Sea of Sand, saying both the Vermillion forces at Mega Monster Amusement Park and the scrapyard are in the best position of retrieving it. Saying that the Blade was now a top priority, Krux ordered Machia to inform Blunk and Raggmunk of the changes of plans.

#### Losing the Time Blade

However, despite originally obtaining the Blade, the ninja stole it from them with the help of Jay's new Lightning Bike. With the mission failed, Blunk and Raggmunk made an excuse to Machia. Though Acronix and Krux were happy, Machia then informed The Hands of Time they failed as she predicted, which angered Krux, asking if they didn't get the Blade. However, Machia reassured him that they will have it soon, using Acronix's temporal anomaly locator to track the Blade in the ninjas' possession.

Once Blunk and Raggmunk returned to base, Acronix and Krux angrily berated the two for their failure, saying they lost it to a bunch of kids. While explaining that it was the blue ninja who used his bike, they revealed they used the Time Blade, which they were not permitted to do, with The Hands of Time saying that if they knew how to use it, they wouldn't have lost it. While claiming that they didn't use it, Acronix berated them for losing the Time Blade, using the Time Blade, and lying about using and losing the Time Blade. The two attempted to reassure The Hands of Time, saying they devised a plan which involved trading the Time Blade with the ninja in exchange for returning Cyrus Borg, but then double-cross them and take the Blade from themselves. Krux then told them that by doing that, the ninja would learn the location of their base, see their master plan, and try to take the Forward Time Blade. He went on to tell them that they need all the Time Blades, including the one they lost. After Machia threatened Borg for trying to sabotage the Time Apparatus, Blunk tries to come up with another plan, but Machia interrupted by saying they need a plan which will work, which gets Acronix's attention. By using Acronix's temporal anomaly locator on his BorgWatch, they knew of the Blade's location, saying all they needed to do is go and get it.

#### Battle of the Temple of Airjitzu

Discovering the Blade was at the ninjas' HQ at the Temple of Airjitzu, the Vermillion warriors, along with Acronix, Krux, Blunk, Raggmunk, and Machia then began their assault by catapulting a Vermillion egg into the temple, which alerted the ninja of their presence. After launching more eggs up to the temple, the ninja easily defeated them by using Spinjitzu, with Blunk telling Acronix that having Machia in charge was a bad idea, but she reassured them that it was only the first salvo and that next they send in "the big boy," using the remaining snakes and armor up at the temple to create a Buffmillion warrior, which the ninja barely succeeded in defeating. The Vermillion then bombarded the *Destiny's Bounty 2.0*, causing it to fall to the ground below. Machia then ordered a full-on assault, saying not to stop until the mission is complete.

Eventually, Lloyd went down to the Vermillion launch site and demolished some of their weaponry, including a Vermillion egg full of swords, which landed next to the commanders but failed to hit any of them. Machia then ordered the sky team to go in, ultimately succeeding in causing Lloyd to lose control of his dragon, but he was saved by the arrival of the new Samurai X. While The Hands of Time ask what is taking so long, Machia assured them that it was only a minor setback.

With that, Acronix and Krux, now armed with the Forward Time Blade, personally attacked the temple themselves, using two Vermillion jetpacks to reach the temple grounds. As Cole, Nya, Lloyd, and Zane charged towards the two, Acronix and Krux held hands as Acronix used the Forward Time Blade to teleport the two of them directly to Kai and Master Wu, punching both of them down to the ground. Acronix then went after the weakened Wu with the Forward Time Blade, but Cole throws Wu the Slow-Mo Time Blade, which he used to defend himself. As Acronix told him that is luck is about to run out, Wu used the Slow-Mo Time Blade on Acronix, causing him to slow down. With this opportunity, Wu threw the Forward Time Blade out of Acronix's hand and onto the ground, allowing Krux to obtain it. As Kai battled him with the Slow-Mo Time Blade, Acronix became free of the Slow-Mo Time Blade's time bubble effect, claiming a discarded sword and attempting to help his brother, but was stopped by Jay and Lloyd.

As the fighting continued and the ninja disposed of the arrival of Vermillion reinforcements, Cole pounded the ground, sending a shockwave that knocked everyone down. Now in a similar predicament, as they were forty years ago during their battle with the original Elemental Masters in the forest, Acronix and Krux picked up Lloyd by his feet and swung him around, knocking down the others before throwing him to the ground. While Jay fought Acronix, Kai thew Lloyd the Slow-Mo Time Blade, who used it to battle Krux. As the two locked Time Blades, Lloyd managed to swing Krux around, launching him into his brother and dropping the Forward Time Blade, which Cole caught and gave to Lloyd. As the ninja celebrated, Machia arrived and took both Time Blades from Lloyd, landing next to The Hands of Time. Machia then slowed down the ninja with the Slow-Mo Time Blade. Telling the two that the Time Blades belonged to them, Acronix ordered Wu to be captured as Machia's airship arrived. As the four boardded, Acronix said they are wasting precious time before the ship fled the area with Krux, Acronix, Machia, both Time Blades, and Wu all on board.

#### Final Stages of the Plan

Now armed with both Time Blades, Acronix and Krux led the Vermillion warriors back to base. The two then began to taunt Wu, suggesting he's gone deaf with old age. Wu told them that he could hear every one of their attempts at humor, but Acronix and Krux laughed it off as they continued onwards. Krux then called for Blunk and Raggmunk, telling them that he and his brother have been concerned for the leadership of the Vermillion warriors, saying that their mission didn't go quite as planned. While the two generals believed Machia would be in trouble, Acronix told Machia that he and Krux were impressed with her actions, ultimately promoting her to the Supreme Commander of the Vermillion while demoting Blunk and Raggmunk to order under her, which angered Blunk and Raggmunk, but Machia put them in their place. Wu then asked them if all of this promotion was premature, saying his ninja were still out there, but as they arrived at the Vermillon Swamps, Acronix informed him that they had no master, no Time Blades, and certainly no chance. As Acronix taunted Wu by saying he *almost* feels sorry for them, the group laughed excluding Wu. Acronix then began to use his BorgWatch, which angered Krux. Acronix told him he was sharing this victory with his Instabook followers, texting in that he has achieved total victory. As Krux told him he ruined a good moment with his "techno-garbage," Acronix asked him why he was so stubborn about staying in the ancient past.

Eventually, as the ninja uncovered the location of the Vermillion Swamps, Acronix, Krux, and Machia threatened Borg again for stalling in the construction of the Time Apparatus. As he returned to work, the three of them laughed.

During one of Wu's hallucinations, Acronix and Krux arrive as one of Wu's many mistakes, with Acronix saying Wu never should have come all by himself.

#### Obtaining the Third Time Blade

While Krux talked with Borg once the Time Apparatus is completed, Acronix arrived with Machia, saying the third Time Blade is about to arrive. Krux then removed the Slow-Mo Time Blade from the apparatus and left with Acronix, Machia, and Cyrus Borg to retrieve the third Time Blade. Traveling to the Glacier Barrens, Krux questioned Acronix on the Blade, with Acronix saying it was about to arrive in just a moment. On cue, the Temporal vortex opened in the sky above, releasing the Pause Time Blade. As it landed, it paused all of Time. Once its effects wore off, Krux claimed the Blade, with Acronix telling him that the BorgWatch worked perfectly. He then tried to get Krux to admit that not all modern technology was bad as the third Time Blade was the easiest on to get, but Krux told him that he won't until they find the final Blade, a task which Acronix's BorgWatch could not do. As Acronix returned to Machia's ship, he told himself that their mother always said Krux was stubborn.

#### Capturing Kai and Nya's Family

Machia's ship then returned to the Vermillion Swamps. Krux and Acronix, along with a battalion of Vermillion warriors led by Machia, sneaked up onto the blacksmith shop, where they overheard that the Reversal Time Blade, the fourth and final Blade, was ultimately placed in the Boiling Sea by Ray and Maya under the orders of Wu after they discovered it in the woods below the monastery, saying they only the Masters of Fire and Water could get it. After Maya realized that Kai and Nya could be used, the group was about to leave but Krux and Acronix arrived, wanting them to obtain it for them. After pausing Ray with the Pause Time Blade and revealing Wu, Acronix told them that the Reversal Time Blade was the only way to undo the effects of the time punch on Wu, with Krux saying that if they wanted to save Wu, they will retrieve the fourth Blade for them. Acronix, Krux, Machia, Wu, Kai, Nya, Ray, and Maya boarded Machia's ship and proceeded to the Boiling Sea, passing over the other ninja as they were confronted by the Vermillion lead by Blunck and Raggmunk.

#### Obtaining the Final Time Blade

As Machia's ship approached the Boiling Sea, Krux told his brother that the final Time Blade will soon be theirs, but Machia wondered if it was just a ninja trick, to which Acronix responded that it best not be for the sake of the dying Wu. Upon arriving, Ray explained they needed the Dragon Blade before taking it from Krux. As Acronix asked him what he was doing, Machia immediately attacked Ray, but he told them that the Dragon Blade is the key in getting them the last Time Blade. As Krux told him that it's only one Blade and that they still have three Time Blades, Acronix said that escape is futile, though he would like to see them try before Krux ordered Machia to give the Blade to Kai and Nya. Acronix then witnessed Kai and Nya create the Fusion Dragon and use it to plunge into the Boiling Sea in hopes of obtaining the final Time Blade.

After a while, Acronix wondered where Kai and Nya are, asking Krux what to do if they failed. At that moment, the two returned on the Fusion Dragon with the Reversal Time Blade in hand. After landing on the ship, Kai rushed to use it on Wu, but was stopped by Acronix and Krux, who revealed they lied about allowing Kai to use the Reversal Time Blade to save Wu, asking him if they expected them to allow Wu to remain after all the trouble he has caused them in the past. A fight broke out, with Acronix fighting Nya with the Pause and Forward Time Blades. However, he was kicked away by Nya after Machia was knocked into Krux. As Kai rushed to Wu's aid, Acronix appeared from behind and prepared to strike Kai with the Forward Time Blade, but Kai was pushed out of the way by Ray, who took the hit instead, causing him to begin to rapidly age. Rejoining with his brother, Acronix then paused the group, with Krux commending his brother for his work. Now with all four Time Blades, Acronix declared it was time to return to the swamps, with Krux asking what to do with the others, with Acronix ordering Machia to drop them off at their current location. After disposing of them, they returned to the Dome at the Vermillion Swamps.

#### Travelling Back to the Past

Upon arriving at the Dome, Acronix and Krux witnessed the other ninja attacking and Zane, Samurai X, and Cyrus Borg attempting to disable the Iron Doom. Ordering Machia to proceed as planned, Krux and Acronix jumped off the ship and landed behind the trio. Krux then paused the trio with the Pause Time Blade just before Zane could put in the final number to disable the Iron Doom, with Acronix saying they had zero chance. After plugging in the four Time Blades into the Time Apparatus and the Iron Doom began to power up, Acronix punched the trio off the side of the scaffolding, but they were caught by Jay, Cole, and Lloyd. Acronix, Krux, and Machia then boarded the Iron Doom after the other Vermillion warriors. As the Iron Doom destroyed the surrounding scaffolding, it charged up and created a Temporal vortex in the skies above the Iron Doom. As Krux told Acronix that it will be ready in just a few more moments, Acronix said that Ninjago will be theirs and that nothing could stop them. At that moment, the Fusion Dragon arrived, to which Krux angrily asked his brother why he jinxed it. As the Iron Doom became fully ready, The Hands of Time then recited their signature quote as the Iron Doom launched into the Temporal vortex, unaware that the Fusion Dragon carrying Kai, Nya, and Wu followed them into the vortex.

The Iron Doom traveled back in time through the Temporal vortex. As Acronix admired the majesty of time travel, he took a picture of the vortex with his BorgPad, saying it wasn't quite capturing the majesty and needed a different filter. However, Krux knocked the BorgPad aside and told him that they were approaching their temporal destination before ordering Machia to ready her troops. As Krux explains to Acronix that decades of planning was finally about to pay off and that the battle will be re-fought, Acronix told him that no one could stop them. The Iron Doom then began to shake violently as it arrived in the past.

#### Altering the Timeline

Landing at the Monastery of Spinjitzu forty years in the past directly after the past versions of Krux and Acronix were lost in time, the future versions of Krux and Acronix confronted the past Elemental Alliance, where Acronix gloated over their confidence. Krux explained to them that they have stopped them once today, but it was before they had a legion spawned from the Great Devourer. After young Wu told the group to focus, Acronix told Machia it was time, who thenordered her Vermillion army into battle.

After Kai and Nya began to secretly help the past Elemental Alliance by posing as Ray and Maya, they begin to defeat the Vermillion. As Krux said they were losing, Raggmunk and Blunk arrived, saying it was only a temporary setback. As Acronix told them that they did not travel across decades to suffer temporary setbacks, Krux nodded to Acronix as they smashed the two generals into their component snakes before taking their helmets. As Machia arrived, Krux then reveals she too has outlived her usefulness as she too was destroyed, with Acronix saying she was relieved of her duties before boarding the Iron Doom.

Using their helmets, Acronix and Krux telepathically smashed the rest of the Vermillion warriors, ordering them to return to the Iron Doom. As the snakes merged with the Iron Doom, Acronix tells the Iron Doom to arise as it came to life and towered over the monastery. Using the Iron Doom, The Hands of Time were able to overpower the Elemental Alliance and capture young Wu, where they explained to him their terms of surrender. Krux told him that if he yielded, they will destroy the Elemental Alliance, but spare the citizens of Ninjago while Acronix told him that if he refusesd, they will still destroy them, but the citizens will not be spared. As Krux asked him to yield, young Wu yielded, ultimately changing the future into their image.

After throwing young Wu back to the other masters, the Iron Doom confronted them, with Acronix asking who they should destroy first between Garmadon and Wu. At that moment, the Fusion Dragon arrived and attacked the Iron Doom. Acronix then said that Ray and Maya are just as bad as their kids. Krux then told him that they *are* their kids, ordering for a maximum barrage. As the Iron Doom fired Vermillion eggs at the Fusion Dragon, they all missed, and Kai and Nya blasted the cockpit with their powers, knocking Krux and Acronix away from the controls. As Acronix sa to fight Fire with Time, Krux tells him he hated his sayings before Acronix ordered for full temporal energy. After the Iron Doom sent a Slow-Mo shot towards Nya, who bailed from the Fusion Dragon to retrieve something, the past Elemental Alliance distracted the Iron Doom. With this distraction, Kai slammed the Fusion Dragon into the Iron Doom, causing it to fall onto the structure and look down the cliffside in a similar fashion as to Acronix and Wu's fight at the ruins of the monastery in the future.

After getting the Iron Doom back up, Krux said that he will destroy Kai and Nya even if he must do it with his bare hands. Acronix then told him that they still have the Iron Doom and that they can go anywhere in time they please, saying that if the battle was too difficult in the past, they should go to a time where they are sure of a victory and a time where Kai and Nya do not exist. As Krux suggested going further back in the past, Acronix told him the opposite; far into the future. Using his helmet, Acronix used the Iron Doom to open another Temporal vortex. Just before they could leave, the Fusion Dragon attempted to strike it one last time, but Acronix ordered it to duck. As the Fusion Dragon de-materialized, the Iron Doom entered the vortex as it closed behind them. Unfortunately for The Hands of Time, Nya managed to recover the past Reversal Time Blade from the woods below the monastery and used it to restore Wu. With the past Reversal Time Blade, Kai, Nya, and Wu reversed time so that they could follow The Hands of Time into the vortex.

#### Battle in the Temporal Vortex

As the Iron Doom traveled to the future, Krux complained to Acronix about going to the future. Acronix told him that by going into the future, there would be no one who recognizes them, no Elemental Masters, and no Kai and Nya. At that moment, however, the Time Twins were confronted by Kai, Nya, and Wu. As a final battle between them begins, Krux fought Kai while Acronix fights Nya and Wu.

As the Iron Doom began to pass by the present, Krux and his brother defeated the ninja and were about to finish off Kai and Nya, but were stopped by Wu. As Acronix told him was nothing he could do, Wu then ripped out the Reversal Time Blade from the Time Apparatus, causing the Iron Doom to spin out of control. After giving the Reversal Time Blade to Kai and Nya before they returned to the present so that they can cure Ray of the time punch, Wu confronted a defeated Krux and Acronix, saying that it would indeed end now. As the three fought, the Iron Doom became lost in time with them still aboard as it traveled far into the future.

#### Battle Through the Timeline

After being lost in time, Krux and Acronix battled Wu. Wu became supercharged with Reversal time energy, causing them to go back in time to the Fire Temple in 2012, just before Kai unlocked his True Potential. Krux tried to attack Lloyd, but Wu stopped him, causing them to return to the Iron Doom, where they discovered Wu was becoming younger due to the Reversal Blade, upsetting Krux. They were then transported to the Temple of Light later in the same year, where they tried to attack the ninja again but Wu once again prevented them from doing so and the three were transported outside the Monastery of Spinjitzu while child Wu and Garmadon sparred with katanas on the other side of the wall. As the young Great Devourer lurked nearby, Wu's katana flew over the wall. Wu managed to stop Acronix from picking up the sword and lamented that while he wished he could change this moment, as doing so would prevent Garmadon's transformation to evil, he knew he could not, before Krux attacked him and the three warped away again.

Wu and the twins continued to warp across several time periods, eventually ending up back on the Iron Doom, Wu de-aging into a child in the process. Krux mocked Wu's new form, and Wu threw his staff at Krux and ran toward the time apparatus. When Acronix protested against this, Wu responded that the Hands of Time were no more than "second-hand thugs" before touching the apparatus with the Reversal Blade's energy inside him to halt the Iron Doom entirely, completely de-aging him to a baby and seemingly trapping Krux and Acronix inside the vortex.

### Legacy

In 2018, Wu, as a baby, became a target towards a biker gang known as the Sons of Garmadon, due to being part Oni, allowing him to grab the Oni Mask of Hatred, his age at the time meant he wouldn't object to it, and being wrapped up in a map showing how to find it. He slowly returned to his original age by the end of the year.

When Wu regained his memories, he recalled the moment Acronix, Krux, and Wu were all lost in time aboard the Iron Doom.

In 2021, Maya and Nya's relationship was shown to be severely strained because Krux had kidnapped Ray and Maya, leaving their kids to protect them. Maya had eventually explained to her daughter that it was was a big sacrifice, as that sometimes there are no good choices and "that's how the cookie crumbles". Nya eventually realized this when she was forced to merge with the Endless Sea to defeat Wojira, at the cost of her humanity for over a year.

Krux and Acronix were mentioned by Kai when the Ninja and Fugi-Dove went over likely candidates to join the Council of the Crystal King, but Lloyd responded that nobody knew where they were.

## Appearance

Krux is an old man with gray hair combed back and a mustache. He has hazel eyes and a green tattoo with black detailing on his face. He also has gray bushy eyebrows.

When he was younger, his hair was black like Acronix's but chin-length, styled haphazardly, and with swept back bangs. His mustache was also shorter and his eyebrows were identical to Acronix's.

He wears a red, gray, and black suit of armor that consists of red and gray metal plating with gold outlining around his body and has the symbol of Time in the middle. The left sleeve and plating of his armor are gray. His outfit also has a black hood and mask with the symbol of Time and gold detailing on top. He wears a green half cape which sometimes drapes over his right shoulder.

During the Serpentine War, he wore a silver helmet identical to the one Blunck wears. He lost the original when he fell out of the time vortex. He temporarily replaced it with Raggmunk's helmet to control the Vermillion.

Before Acronix reunited with him, Krux's armor became duller, darker, and faded compared to his brother's, considering it became much older. The symbol on his armor started rusting and the top right outline had cracked. He also began wearing an hourglass on his side with a bronze chain on his hip.

While pretending to be the kindly Dr. Saunders, he wore fake glasses and makeup to cover his tattoo, as well as a fake long mustache to hide his real mustache. His hazel eyes were colored black, (presumably because of contact lenses). He wore a maroon coat with pockets, one holding his pocket watch, and two pictures of the museum, a red shirt with orange outlining, and gray pants.

## Personality

Krux is shown to be a ruthless individual, as he had threatened the lives of two children to get their parents to comply with his demands. He truly despises Wu and Garmadon for defeating him as well as separating him from his brother for decades. His grudge extends to anyone related to them since he despises Lloyd for being the son and nephew of his foes.

He is proven to be a patient person, as he waited forty years to be reunited with his younger brother Acronix and for his plans to strike back at Wu. He has some sense of honor, keeping his end of the deal to leave Kai and Nya alone if Ray and Maya worked for him.

It appears Acronix is the only person he genuinely cares about as he waited decades to reconnect with him and the first thing he did in their reunion was hug him. The pair make a great team, as they are quick to defend the other. He had sought to rule Ninjago with him and tries to get him to under his plight of being surrounded by technology though at times he relies on it.

Krux had grown up in Ninjago without technology so when he saw it rise, he despised it, unlike his brother. He is easily angered by Acronix constantly loving technology, but didn't let his hatred extend to him. However, Krux is not above admitting that technology has its uses but still doesn't like it out of pride. According to his mother and brother, Krux is also stubborn and won't change his views. While normally calm, he also has a short temper which gets the better of him. Krux has shown to not like loud noises or having his picture taken.

As Dr. Saunders, he pretends to be a somewhat eccentric but kind-hearted museum curator. He acted very cheerful and helpful, though all of this was just a façade while he was preparing Acronix's return. He used this to lie to the Ninja that he and his twin were a myth to stay under their radar.

## Powers and Abilities

### Powers

* **Time Manipulation:** Krux was gifted with half of the ability of Time, specifically Reversal and Pause. He used this to great lengths, often using them to get the advantage over his opponents. His powers were eventually stolen by Wu and Garmadon and stored in the Time Blades.
	+ **Temporal Rewind:** Krux was able to rewind time. This can be used to restore youth or to negate a dangerous situation by reversing time until a moment prior to the event, allowing him to adjust or prepare accordingly. This appears to involve yellow-orange temporal energy. This power is currently stored in the Reversal Time Blade.
		- **Retrokinesis**: Krux presumably was able to reverse someone's age to make them younger.
	+ **Time Stopping**: Krux was able to pause time, freezing the target of their power. This appears to involve red temporal energy. This power is currently stored in the Pause Time Blade.
* **Hive Mind**: With Raggmunk's helmet, he can control the Vermillion.

### Abilities

* **Skilled Combatant:** Krux is a highly capable fighter, being able to fight both sons of the First Spinjitzu Master at once and later being a nearly equal match for Kai despite his old age.
* **Swordsmanship**: Krux is a skilled swordsman.
* **High Intelligence**: Krux has shown to have a high intelligence. He is rather knowledgeable in Ninjago's history, which helped him maintain his cover as a museum curator.
	+ **Master Strategist**: Krux is a very strategic person. He was able to come up with a plan to go back in time to rule Ninjago with the help of the Vermilion in the past forty years.
	+ **Mechanism**: Despite hating technology, he's a rather knowledgeable on how to use and build such devices.
	+ **Vermillion Biology**: Krux knows how to care for the Vermilion so the eggs can hatch and understands their abilities. Krux had bred the Vermillion from the eggs from the Great Devourer. He was able to create the Vermillion commanders; Blunck, Raggmunk, and Machia through breeding the most genetically superior Serpentine.
* **Expert Acting**: Krux was able to pretend to be the eccentric but kind and cheerful museum curator Dr. Sander Saunders for years.
	+ **Vocal Alteration**: Krux can change his voice with ease, specifically making it higher and with a peculiar accent. He used this to disguise his voice when he pretended to be his persona, Dr. Saunders.

* **Stubbornness:** Krux is very stubborn, preventing him from accepting his brother's change in personality, causing them to argue constantly.

## Behind the Scenes

* Acronix and Krux were originally meant to be one character, named "Kronos."
* Krux's name comes from Crux, a file-sharing software used in the production of the TV series.
	+ Coincidentally, Crux is also the name of the main setting for LEGO Universe, in which LEGO Ninjago: Masters of Spinjitzu had a role.
	+ Crux also means "the decisive or most important point at issue".
* The younger version of Krux was released as a Minifigure in the 2017 Ninjago Bricktober set, with the most prevalent change being his new, younger face, as well as his outfit and armor being brighter and vivid like Acronix's.
	+ His young figure is shown to have some printing errors. Some elements of the hourglass from his older figure appear on the young figure. The hourglass part on his hip piece, a small silver triangle, and the bronze chain in his back that was attached to his hourglass. However, the other elements are missing, like the chain over his legs and the top half of the hourglass, meaning that the torso of the old Krux figure was likely copied and altered to do the print on young Krux’s torso.
* His outfit and armor are more dull and faded than his brother's, most likely due to his being older.
* He has an hourglass printed onto his torso, as a sign of his preference for a low tech life.
* Chen and Clouse manipulating the twins into betraying the alliance was originally a scrapped idea for The Hands of Time.
* Krux is one of the five main antagonists to have appeared before the installment where they are the main antagonist, the others being Sir Fangar, Morro, Yang, and Ronin.
* He and his brother are two of the eleven Ninjago characters to have a cape in the sets, the others being Lloyd, Chen, Morro, Harumi, the Blizzard Sword Masters, Wu, Akita, and Mammatus.
* He is the third major Lego villain to have a hidden identity, the first being Pythor in Rebooted and the second being AntiMatter in Ultra Agents.
* Though the colored detailing around the Krux and Acronix's eyes was simply a designer's choice with no specific explanation, one possibility is that they are tattoos and Krux wore makeup to cover his when he was disguised as Dr. Saunders.
	+ "Pause and Effect" is the only episode in which Krux's face is shown (albeit in a flashback) with neither his fake glasses and mustache or his eye detailing.

## Trivia

* Just like Kai, Krux despises technology, though his dislike is more extreme as he claims technology ruined Ninjago.
	+ However, Krux did reluctantly admit that sometimes modern technology has its uses after Acronix's BorgWatch found out the locations of the Slow-Mo and Pause Time Blades. Though, he still admitted his dislike of it as his brother stated their mother always called him stubborn.
	+ Ironically, as Acronix is young and loves new modern technology, Krux is old and prefers the old ways of life. This is also shown with his Elemental Powers of being able to freeze and rewind time, whereas his brother can slow down and speed up time.
* It's mentioned that Cole enjoyed some of the tours of the museum when Krux was disguised as Dr. Saunders.
* If he and Acronix's family wielded a different Elemental Power, Krux would have sole control thanks to being the firstborn twin while Acronix would be a normal human.
* Krux is chronologically three minutes older than his twin brother Acronix, but because his brother was lost in time for four decades and didn't age, he is now biologically forty years older than him.
* Krux appears alongside his brother as a boss in The LEGO Ninjago Movie Videogame and can be unlocked as a playable character by achieving silver medal status or higher in the said dojo, which requires the player to accumulate at least 50,000 studs.
	+ In the game, Krux emits red energy from his hands despite being depowered, although he can't use his elemental powers in-game and instead can disguise himself as Dr. Saunders.
	+ Curiously, Krux wields a spear and a shield as a boss but wields a Vermillion axe as a playable character.
