Cole is the current Elemental Master and Ninja of Earth and the son of Lou and Lilly. He was recruited by Wu. With Wu'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 warriors, 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 Battle of Stiix, 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 Ninjas' 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. Though 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. 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 four Ninja and 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 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, 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, defeating the Skull Sorcerer, and fulfilling a promise he made to his mother, Lilly. Cole, Wu, and the other ninja later leave Shintaro but prepare to go on another adventure.
