Cole is the current Elemental Master and Ninja of Earth, and the son of Lou and Lilly. He was recruited by Wu, and with the old man's help, Cole learned Spinjitzu and discovered his other teammates, with whom he embarked on many adventures; battling the likes of the Serpentine and the Stone Army. After the Final Battle, peace resumed until the Overlord returned and created the Nindroid Army. The Overlord made the Nindroid Army by using Zane's blueprints. During this time, a love triangle formed between Nya, Jay, and Cole. The conflict ended when Zane sacrificed himself to vanquish the Overlord. Saddened by Zane's death, the ninja parted ways but reunited after learning of Zane's survival and set out to rescue Zane on a mysterious island. There, Jay and Cole made amends over Nya, while the ninja allied with the Elemental Masters to defeat Chen's Anacondrai Cultists, who had caused the Second Serpentine War. Shortly after, the ninja battled Morro and spirits from the Cursed Realm. Needing to learn Airjitzu, the ninja went to the Temple of Airjitzu, where Cole was turned into a ghost. He soon came to terms with his condition and used his new abilities. Following the ghost invasion, the ninja were tormented by Nadakhan, who captured Cole in the Djinn Blade. After Cole and the others were freed, Jay used his last wish to undo recent events. On the Day of the Departed, Cole confronted Yang, who tricked Cole into reviving the ninja's old enemies. Cole fought Yang, but eventually made amends with him, and Cole became a human once more via the Rift of Return. Cole joined his allies in battling the Time Twins and their Vermillion army, as well as seeking the powerful Time Blades. Although their enemies were defeated, Wu was lost in the time vortex but was rediscovered a year later in the form of a baby by Cole, as he liked to drink tea and wouldn't drink anything else, as well as acting like Wu. Cole protected the de-aged Wu from a notorious gang that resurrected Lord Garmadon, and the two were later stranded in the Realm of Oni and Dragons with the original ninja looking for a way home. After the defeat of Iron Baron (the leader of the Dragon Hunters), Cole, along with the other original ninja and a middle-aged Wu (now the Dragon Master), returned home with the help of the Dragons. They managed to defeat the Colossus while Lloyd defeated his father, saving Ninjago once again. Cole fights alongside his friends to defend against the Oni invasion but falls into the darkness attempting to rescue citizens. However, he survives and comes to the monastery to defeat the Oni and witness Jay ask Nya to be his Yang. Months later, Cole and his friends fight against Aspheera and her Pyro Vipers after accidentally releasing them from their tomb. After Zane is banished by Aspheera's sorcery, he and the remaining ninja send themselves to the Never-Realm in order to rescue him. While Lloyd went to find Zane, Cole and the others protected the Ice Fishers of Great Lake. Cole befriended Krag the Yeti in the mountains, who led him to the Traveler's Tree, allowing them to use its berries to make a potent enough dose of tea to go back home. The ninja fight Boreal the Ice Dragon, and discover that Zane is the Ice Emperor. With Zane having managed to return to his senses in a fight with Lloyd and freeing the Never-Realm from its eternal winter, the team reunites and use Traveler's Tea to head back to their home realm. Sometime later, Cole and the other ninja enter the virtual world of Prime Empire when the legendary arcade game resurfaces, and hundreds of gamers are zapped into it. He and Kai sacrifice their last of their four lives to save Jay, Nya, and Lloyd in the Speedway Five-Billion. Eventually, Jay moves on to convince Unagami to free everyone trapped in the game, and Cole, as well as the other ninja, gamers, and NPCs are freed. Afterward, Cole travels to the Kingdom of Shintaro on top of Shintaro Mountain, where he discovers Dungeons that were made by an evil sorcerer Hazza D'ur underneath the mountain and the evil Skull Sorcerer. He gets captured but is later saved by the other ninja. He returns to the surface, but the King, Vangelis, reveals that he is actually the Skull Sorcerer, and banishes him, Princess Vania, and Wu to Rock-Bottom. There, they meet the Lowly. Together, they escape from Rock-Bottom and Cole faces the Skull Sorcerer, unlocking the power of the Spinjitzu Burst, which he used to defeat the Skull Sorcerer and fulfill a promise he made to his mother. Cole, Wu, and the other ninja later leave Shintaro but prepare to go on another adventure. Cole traveled to the Island of the Keepers to save Misako and Wu. There, the ninja discovered the Storm Amulet and the existence of Wojira. When Nya lost control of her powers, he stayed behind at the monastery along with Kai while the others went to investigate. Later on, he attempted to stop Kalmaar from awakening Wojira, but ultimately failed and he assisted the other ninja in the fight that followed. He was saddened when Nya left, and attended her memorial, as well as silently comforting Jay during this time. One year later, Cole unites the ninja team to solve a Vengestone hoarding from some henchmen, but they run into and form a rivalry between the New Ninja. Later, after realizing a way to bring Nya back, Jay and Cole break into Borg Tower to steal Aspheera's staff, but were unsuccessful. The ninja, however, manage to stow a truck containing it and allow Aspheera, who was freed by Kai, Zane and Lloyd, to steal Nya's powers and become human again. At a cost though, the ninja become criminals and are placed in Kryptarium Prison. When hearing word about the Overlord, now known as the Crystal King, is summoning the ninja's worst enemies against them, the ninja break out of prison thanks to Dareth, and have Lloyd go undercover with the Council of the Crystal King. As the ninja search for Lloyd under the N line, the tunnel is blown up by Crystal Spiders and are trapped under rubble until they are saved by Nya in her Samurai X Mech, and the ninja regroup at the Samurai X Cave to save Lloyd and plan to stop the Overlord's invasion and save Ninjago. Eventually, Cole and the original ninja unlock their Dragon Forms, reclaim their Golden Weapons and unite them to prevent the Overlord from corrupting them, becoming crystalized in the process. However, the powers formed the Golden Ultra Dragon and defeated the Overlord, freeing everyone from the Overlord's reign. Cole and the other ninja, alongside their allies, rebuilt the Monastery of Spinjitzu. Several weeks later, Cole moved to a farming village, where a dispute was in progress, and thanks to his visiting father and the farmers, he regains his powers in the process before leaving the village with his father. Later after the Merge, Cole was separated from his fellow ninja, and woke up in the Land of Lost Things, where he encountered a Munce exile named Geo and started to protect the children living there from a creature called the Hoarder, using his powers to transform into a golem, which he thought was powered up from Geo's Fusion powers. One such encounter, he attacked three suspicious individuals before discovering Nya was one of them and learn the Claws of Imperium were after the Dragon Core, which is stolen by Dr. LaRow. When time came to attack Imperium, Cole stayed behind, only to start following Sprite, who was projecting Wu's voice. At some point, he returned to the monastery upon learning Kreel had been gathering Chronosteel to sell in her junkyard, but prevented her after Lobbo was infected by a dangerous artifact. Later, Cole helped the other ninja stopping the Mechanic from stealing mechs in the Mech Master 5000 and stopped Lava-Tides from stealing dragon eggs. After finishing his mission, Cole returned to the Land of Lost Things, where he found out that the Wolf Clan planned to abduct Bonzle and exploit her to unlock a gateway for the Forbidden Five's release. In order to protect her, Cole and Zane embarked on a journey to Mysterium to find Bonzle's creator, Gandalaria. Despite the help of the sorceress, Bonzle is finally kidnapped by Jordana in the Wyldness. Eventually, Cole, Zane, and Gandalaria joined forces to save the Cloud Kingdom from imminent destruction while the others prevent the Blood Moon Ritual, at the cost of Kai and Bonzle being banished to the Nether-Space. When three Arc dragons were murdered sole time later, Cole joined the ninja as they participate in the Tournament of the Sources, where he battled Arin's old friend, Frak, and lost, but gave him advice during the latter's battle against Zur. Guided by a light, Cole came across the Monastery of Gates where he learned from Wu's ghost that he was responsible for the Merge. After Nokt won the tournament, Cole and the ninja attempted to stop the former as he released the rest of the Forbidden Five before Nya was able to free Kai and Bonzle with Riyu's help, and Nokt had the seized powers stripped and returned to their rightful owners before watching the Forbidden Five, along with Ras and Arin, escape through a Portal Gate, which became destroyed. Weeks later, Cole stays in the Land of Lost Things, while his teammates embark on several journeys which ultimately lead to them confronting Thunderfang. Cole notices the Winds of Chaos and keeps an eye on the Finders. After Thunderfang's death, Cole reunites with the ninja and an amnesiac Jay. Cole is briefed on recent developments; Arin and Sora accompany Ras in hopes of bringing back Arin's supposedly deceased parents. However, Jay interrupts the conversation and reveals that they are still alive.
