Ronin

You may be looking for the non-canon character from Shadow of Ronin.

Ronin is a selfish yet skilled and intelligent thief. Based in Stiix with his airship R.E.X., Ronin left a bad impression on the Ninja during their first encounter, as he hoped to keep the Scroll of Airjitzu for himself. Yet, when Morro obtained it, the Ninja were purged into a quest to learn Airjitzu and find the Tomb of the First Spinjitzu Master. Looking to change his ways, Ronin sided with the Ninja, and oversaw Nya as she tried to master her water element.

When the Ninja gained the upper hand and retrieved the Sword of Sanctuary, Morro forced Ronin to steal it, threatening to have him banished to the Cursed Realm if he didn't. Fearful of his own demise, Ronin stole the sword and gave it to Morro, who used Ronin to trick the Ninja into heading to the Caves of Despair, where they almost died. As a result of this, Ronin gave the Ninja R.E.X. so that they could find the Tomb, and they succeeded in doing so.

Despite their success, Morro and the freed prisoners of the Cursed Realm occupied Stiix. In an effort to give the Ninja a fighting chance, Ronin intervened and tried to subdue Morro, but he failed to prevent the arrival of The Preeminent. Alongside Wu and Misako, Ronin fought off against The Preeminent and eventually boarded a steamboat that left Stiix with its citizens.

History
Ronin, at one point, became indebted to Soul Archer, who threatened to have him banished to the Cursed Realm if he didn't pay him back. Ronin was reluctant to pay him, but after he was banished to the Cursed Realm, the deal had seemingly disentegrated.

Following the The Overlord's destruction, Ronin captured the newly-rebuilt Zane and P.I.X.A.L. and sold them to Master Chen so he could lure the other four ninja into participating in the Tournament of Elements.

Ghost Story
Ronin stole Sensei Yang's Airjitzu scrolls from the ancient library of Domu and returned to Stiix. He was also briefly seen at the Biker Tavern as Morro arrived and left before he summoned Wrayth.

Stiix and Stones
As Ronin was setting a pot out that hid the scroll at his shop in Stiix, the Ninja arrived seeking it. The thief attempted to sell them weapons such as Aeroblades or Jadeblades, but they were relentless in asking for the scroll and he offered the price of 200, but raised it to 400 when he learned of its value. Kai attempted to barter with him, but due to his poor negotiating skills, they settled on the price of 450. After the Ninja left the shop in search of money, Ronin pulled the scroll out and inspected it.

That night, he was confronted by Soul Archer and Morro who also sought the scrolls. Ronin tried to stall by trying to purchase the Allied Armor of Azure, but they were interrupted when the Ninja arrived. After Morro escaped with the scroll, he rescued Kai and told him there was another way to learn Airjitzu: in exchange for this information, however, he had the Red Ninja give him all the Ninjas' shares of the tea farm as compensation for his shop being destroyed.

The Temple on Haunted Hill
Ronin comes to the tea shop and tells Misako, Nya, and Wu about the deal he and Kai made. When a customer is leaving, Ronin takes the treat Misako gave the man and points out it's a business, not a charity. Nya pays him to take her to her Samurai X Cave. On their way, Nya gets Ronin to reveal that he made a bet with the Soul Archer, and if he did not pay him back, then his soul would go to the Cursed Realm. When they find out that Morro have already arrived in the cave, he uses an Aeroblade to take out one of the Soul Archer's arrows. After Nya's mech got possessed, Ronin saves Nya and takes her outside where the ghosts try to take Ronin's R.E.X. but fail when Nya makes it rain. Ronin then told Nya that she is a Water Ninja.

Kingdom Come
Ghoultar was brought aboard the Bounty and Ronin questioned the ghost along with Wu and Nya. However, when the ghost refused to answer, Wu decided that the time would be better spent training Nya and the two left, leaving Ronin in charge of the prisoner. Later when Kai got the Sword of Sanctuary from Morro, Sensei Wu says they they can now find the Tomb of the First Spinjitzu Master, though Ronin killed everyone's mood by pointing out they still didn't know where the tomb is.

The Crooked Path
While the ninja set up a ghost security system and Wu and Misako try to figure out the last clue, Ronin washed R.E.X. while observing Nya's training. Upon hearing she unlock her powers after overcoming her fear of failure, Ronin told her not to try so hard: as a result, she reversed the falls of the droplets while lecturing him on why she works hard. Before he could get back to washing R.E.X., he was telepathically contacted by Bansha, who told him to bring Morro the Sword of Sanctuary in exchange for removing his curse.

He began to look around the tea shop for it only to nearly get caught by the ninja. As they discussed how they could find the tomb, Ronin snuck out and went to search in the side buildings only to find Nya with the sword, having picked up on his plan due to his advice. The two began fighting, though it ends with Ronin getting the sword. As he attempts to get away, he is surrounded by the ninja who end up falling for their own ghost traps. He enters the shop and is blocked by Wu and Misako though uses the sword to counter their moves and escape out the back. He then fooled them into thinking he escaped in R.E.X. by setting her on autopilot and sailed down a stream on a raft only to be caught by Nya. Although she learned how to reverse water, she wasn't strong enough to pull Ronin's raft back giving him the chance to escape.

He soon arrived in Stiix and found out the Ghost Warriors were hiding out in his old shop. After Ghoultar confirmed he brought the real sword, Morro allowed him his soul back but changed the deal: he now wanted Ronin to capture the ninja so they wouldn't interfere with The Preeminent's return. Ronin refused as he now saw the ninja as his friends, something the ghosts found hard to believe. However, he wasn't allowed to leave and was possessed by Morro so he could send them off to the Caves of Despair. Afterwards, he left Ronin in Stiix while he, Soul Archer and Bansha took Lloyd to find the tomb and Ghoultar went to finish off the ninja, claiming he was no longer of any use to them. Ronin then sent R.E.X. to save the ninja and explained everything in a recorded message, giving them the coordinates to the real tomb, wishing them luck in stopping Morro and telling them this would be the last they hear from him and if Nya wants an explanation as to why, it would be because he cares.

Curse World - Part I
Staying in Ninjago City during New Years', Ronin ate at Chen's Noodle House and made friends with Skylor. While watching the festivities at Stiix, he learned of the Ghost attacks and traveled there in R.E.X., arriving just as Lloyd began fighting Morro. Using all the money he made, he dumped it on his shop which Morro was levitating in midair, causing it to come crashing to the ground, though couldn't find Morro.

Curse World - Part II
Ronin soon began ordering the civilians to get on the ferry and obtains the Sword of Sanctuary to fight off the Preeminent's tentacles. When everyone is boarded, Ronin battles Morro over the Sword, which he eventually lost. He then took to driving the ferry until the Preeminent's destruction at Nya's hands.

Public Enemy Number One
Ronin is showed to oppose the Ninja as he tries to catch them to win a big budget from the police forces.
