Jay Walker (born Jay Gordon[1]), currently operating under the alias Rogue is the current Elemental Master of Lightning, the former blue ninja, and the adoptive son of Ed and Edna Walker, surrendered by his biological parents, Cliff Gordon and his wife. He learned skills including Spinjitzu and discovered his other teammates, Cole, Zane, Lloyd, and Kai, with whom he embarked on many adventures; battling the likes of the Serpentine and the Stone Army. During this time, Jay formed a romantic relationship with Nya. After Lloyd defeated the Overlord, peace resumed in Ninjago until The Overlord returned again and created an army of Nindroids that were made from Zane's blueprints. A love triangle formed between Jay, Nya, and Cole, which remained after Zane seemingly died. The ninja parted ways after Zane's death, but upon learning of his survival, they journeyed to Chen's Island and entered the Tournament of Elements. Cole made amends with Jay over his relationship with Nya, and the ninja and Elemental Masters fought the Anacondrai Cultists. Soon after, Jay would help the ninja battle Morro and a legion of cursed spirits while learning another martial art called Airjitzu, and they were then faced with Nadakhan, who trapped many of the ninja in his sword. Jay and Nya battled the Sky Pirates, but when Nya was poisoned by the Tiger Widow venom and killed, Jay used his last wish to undo the recent events and save Nya. On the Day of the Departed, Jay and his parents were attacked by a revived Samukai, who Jay defeated with help from Ronin. Jay joined his allies in battling the Time Twins and the Vermillion, as well as seeking the powerful Time Blades. Though their enemies were defeated, Wu was lost in the temporal vortex. A year later, Jay helped battle a notorious gang that resurrected Lord Garmadon and was ultimately stranded in the First Land with the other original ninja and Wu. During their first week being stranded in the realm, Jay temporarily loses his sanity and ends up being captured by the Dragon Hunters along with Kai and Zane. After hearing Lloyd's voice on a radio, Jay regains his state of mind and devises a plan to free Zane, Kai, and himself from the Dragon Hunters, and designs a Firstbourne Mech to provide a distraction. They manage to escape with Cole and a growing Wu's assistance before meeting a Hunter named Faith who tells them about the Dragon Armor and they immediately head for it. Wu manages to find the armor and becomes the Golden Dragon Master, and with the Firstbourne and some dragons, they return home to Ninjago to help the Resistance defeat Colossus, while at the same time, Jay reunites with Nya. Shortly afterward, Jay decides it's time to ask Nya to be his Yang. He sought out advice from Kai but his plans get put on hold when the Oni invade Ninjago. During the final battle at the Monastery, he finally mustered up the courage to ask Nya, which she happily agrees to. After using the Tornado of Creation on the Oni, Jay joins his fellow ninja in the creation of the new mural. Months later, Jay 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, Jay and the others protected the Ice Fishers of Great Lake. 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 the berry Krag gave Cole to head back to their home realm. Sometime later, Jay is the first of the ninja to enter the virtual world of Prime Empire, resulting in the legendary arcade game resurfacing and hundreds of gamers getting trapped in it. Jay becomes known as Superstar Rockin' Jay to the League of Jay. The ninja enter in search of the Key-Tanas and Unagami, thinking that finding him would solve the situation. But by the time the ninja get the last Key-Tana, Jay and Nya are the only surviving ninja left in the game. The duo progresses but Nya gets cubed in the process, which makes Jay distraught and the only ninja left, so he moves on to follow Unagami through the completed Manifestation Gate into Ninjago. He and Milton Dyer successfully console Unagami into releasing the formerly trapped gamers, as well as everyone who was formerly cubed, including the ninja (Kai, Cole, Lloyd, and Nya). Later, Jay and the rest of his friends were invited to Shintaro in honor of Princess Vania's birthday. Shortly after arriving, the ninja were forced to split up inside the mountain the kingdom lied on when they were under the attack of the Skull Sorcerer. During his time with the Munce who lived in the Dungeons of Shintaro, Jay was caught in a love triangle between Nya and Murtessa, the Queen of the Munce. He and his friends convinced the Munce to work with the Geckles and vice versa to defeat the Skull Sorcerer. They were successful and they departed on search for another adventure. The Ninja then traveled to an island in search of Wu and Misako. It was there that they were captured by the Keepers and Jay was hailed as the "Gift of Jay." Initially thinking they wanted him to be their king, Jay was delighted until realizing they wanted to sacrifice him to the ancient sea serpent, Wojira. Fortunately, it was just a fake built by Ronin to steal the islanders' fortune and Jay and the other ninja found Wu and Misako and made amends with the Keepers. After Nya's powers go haywire during an attempt to stop a bunch of criminals, Jay and a few of the others traveled under the Endless Sea to investigate what could be the source of the problem. During the adventure, Jay would continuously comfort Nya over her problems. When they realized that the problem behind Nya's powers was Kalmaar trying to awaken Wojira with fake Storm Amulets, the ninja did everything in their power to stop him from getting the real one. Despite their efforts, Kalmaar managed to awaken Wojira and Jay was left in critical condition due to inhaling a large amount of water, causing him to suffer from air drowning. Nya then decides to merge with the sea to draw the water out of Jay and defeats Kalmaar and Wojira. She then says goodbye to her friends as she dives into the ocean. Jay was the most saddened by her fate and fell into depression. A year after Nya's departure, Jay moved to Lighthouse Island and essentially became a hermit before learning from Nya that the only way to return her to normal is to remove her Elemental Power. While Kai, Zane and Lloyd break Aspheera out of Kryptarium, Jay and Cole fail to recover her staff, which is later revealed to be in the hands of the New Ninja, but manage to steal it, and return Nya back to normal before being arrested by them and sent to Kryptarium, where they learn of the Crystal King. After Nya and Dareth break them out, Jay, along with Cole and Lloyd, as well as fellow convict Fugi-Dove, separate from the others to evade the police and reunite at Twitchy Tim's gas station, where they form a plan to infiltrate the Council of the Crystal King. Several weeks after the Overlord's defeat, Jay and Nya went on a vacation, where he stumbled upon Unagami before discovering a lost city and regains his powers while helping Unagami escape. During the Merge, Jay used a mech to help civilians get to safety. When he and the other Ninja went to what seemed to be the center of it in Ninjago, the Merge finished, and he got separated from his friends and lost his memories of being a ninja. He found himself alone in the Land of Madness, where he was found by Administration Agents and became the manager of the Administration's Department of Reassignment. While on the hunt to recover Zane, Jay encounters Bonzle, only for Sprite to ambush him and attempt to get him to recover his memories, but it only made him concerned about people discovering his Elemental Power of Lightning before it attempted to continue as he tries to resist. Sometime later, Jay escaped from the Administration, and would later be recruited by Ras to join the Wolf Clan and participate in the Tournament of the Sources as part of his master plan. During the tournament, Jay, powered by Shatterspin, found himself pitted against Nya, whom he accused of dishonesty due to his memory loss. Ultimately, Jay suffered a brief loss of his Elemental Power when he was defeated by Nya in the tournament. Following his defeat, Ras dismissed Jay, who expressed his hatred for Nya before leaving into unknown parts. After the tournament, Jay eventually regained his Elemental Powers thanks to Roby and became a bounty hunter under the alias Rogue. He would eventually be hired by Zeatrix to locate Ras and bring him to her. In the course of his mission, he found Ras and Arin deep within the World Forest. Due to the intervention of Drix who captured Ras, he, in his drive to finish his mission, ended up joining the Ninja at the battle against Thunderfang. Unfortunately, Jay sustained injuries during the fight and was subsequently brought back to the Monastery by Nya, where he discloses that Arin's parents are alive and were sent to the Land of Lee by the Department of Realm Reassignment. Jay agrees to help Lloyd, Nya and Wyldfyre find Arin's parents in exchange for money and acquiring Ras for Jay's client Zeatrix.
