|— Neuro to Jay|
|Weapon of choice||Mind|
|First Appearance||The Invitation|
|Voiced by||Paul Dobson|
Neuro is the current Elemental Master of Mind and was a competitor in Master Chen's Tournament of Elements, alongside the other Elemental Masters of his generation. On various occasions, the Ninja tried getting Neuro's help, though he proved to be distrustful. When Chen's true plans unfolded and the Elemental Masters' powers were taken away, Neuro and the others joined together and reclaimed their elements.
After reclaiming their powers, the Elemental Masters united against Chen, who completed a spell that transformed him and his followers into fake Anacondrai. Consequently, an ancient conflict was renewed, giving rise to a new alliance of Elemental Masters that fought against Chen's army at the Corridor of Elders. There, Neuro and his new allies battled the fake Anacondrai, before Garmadon sacrificed himself in a bid to banish their adversaries to the Cursed Realm.
Months after the war's end, Clouse released Nadakhan from the Teapot of Tyrahn. Infuriated over the destruction of his home realm, Nadakhan began trapping the Elemental Masters in the Sword of Souls to eliminate any opposition. At one point, Neuro was imprisoned in the weapon offscreen, but after Jay made his final wish, recent events were erased and he was freed.
Neuro was one of the participants in the Tournament of Elements who boarded the boat with everyone else.
Neuro was among those who succeeded in acquiring a Jadeblade.
Neuro was one of the competitors who advanced through to the next round. When the Ninja asked him to help, he refused as they were competition. After he read Lloyd's mind, he was shocked to find out what Chen is up to and accepts their offer of joining them. He attempts to read Chen's mind but Clouse halts him and questions if he's helping the ninja but he denies this but secretly reads his mind. He then reports to the ninja that Clouse is keeping a secret, which is an Ancient Spell to re-awaken the Anacondrai which involves stealing all the Elemental Powers for the Spell to be completed.
Despite being on the Ninjas' side, Neuro acted as an enemy until they could convince the others of the truth. He was still intrested with being on a winning team and was angered from having his room taken away, resulting in being one of the contestants who joined Chamille's team in the Thunderblade race, being electrocuted by Jay shortly after the race started. He later joined the Ninja after they have convinced the rest of the contestants (except Chamille, Tox, and Shade) about the real purpose of the Tournament.
Like the others, he became interested in Chen's staff when he lied and promised the winner of the Tournament it as the prize. Lloyd, however, was horrified of Chen's lying and blurted out Neuro reading Clouse's mind which causes him to glare at the Master of Mind. Later, he got into an argument with Skylor, who purposely stated he could be the spy. He later became convinced Shade was the spy,along with the others.
For the next round of the tournament, Neuro and the other remaining fighters boarded a blimp and were taken high above the island. Due to his fear of heights, the master of mind became increasingly uneasy until he couldn't take it any more and burst inside the cockpit, only to find it on autopilot. Using the television screen, the fighters were informed by Chen what the objective of the next round was; parachute down to the island to find Nya and the winner would automatically advance to the final round. However upon arriving on the island, Neuro was captured by Chen's men and thrown in a vengestone prison.
After his capture, he and the other capture elemental masters are brought before Chen as the masters lament the fact that they didn't heed the ninja's warning. Neuro remarked tha it took of them being defeated to bring thing together before all of their powers were drained, he along with other masters (except Kai) were taken to the noodle factory to work on making Master Chen Noodles. There they allied themselves with Cole, Zane, and Karlof along with Dareth and the Elemental Masters with other prisoners that were captured by Chen to build a Roto-Jet and escape from the factory. After they escaped they battled alongside Kai, Skylor, Sensei Garmadon, and Nya to destroy the staff. After the staff was destroyed everyone got their powers back and they defeated Chen's forces and captured them but Chen, Clouse and a select few henchmen escaped with Skylor as their hostage. With Chen gone for now, the elemental masters seized control of his island and capturing most of his army, but however Skylor was nowhere to be found. Immediately, the ninja ordered the masters to search for Skylor.
Neuro and Griffin Turner stand guard on Chen's captured henchmen and Turner states he could win Jay's game show before Neuro gets a mental message from Skylor to tell them of Chen's plan and he has Turner relay the message to ninja. When Chen's forces transform into Anacondrai, Neuro and the Elemental Master try to hold them off but are overwhelmed, Neuro is knocked down but Shade comes to his aid and he alerts him of Anacondrai behind him. Neuro and the other masters retreat hold the door to prevent their enemy from entering the palace. They soon bear witness to Chen and his forces leaving in the roto jets to conquer Ninjago while leaving them stranded with no means of escape. The Elemental Masters then bear witness to the arrival of Zane on the Titanium Dragon stating he has faced his fear before Kai and Skylor arrive on the Elemental Fire Dragon supporting Zane's words and stating they could all do it. Seeing this, the elemental masters create their own dragons with Neuro creating Elemental Mind Dragon and leaving to face Chen's army.
The Elemental Masters arrive a day after Chen to find that he has not attacked and are told by Lloyd to keep watch over the city. Later on, Neuro and the other masters stand ready to hold off Chen and his forces who have gathered in noodle trucks but they are surprised when the trucks scatter to various locations. They each pursue a truck only to find them empty and realize Chen separated them to invade without hindrance. The revelation that they put many people in danger causes them to lose control of their dragons.
After being separated by Chen's impostor Anacondrai army, Lloyd met up with him, both driving noodle trucks, as they could not use their Elemental Dragons. He was asked by the Green Ninja to send a message to all of the fighters, telling them to meet up in the Samurai X Cave. He then fought in the battle at the Corridor of Elders.
