Warden Noble (formerly Principal Noble) is the warden of Kryptarium Prison and the former principal for Darkley's Boarding School for Great Children. Noble was present at the boarding school when its students took over the building, though the ninja soon came to intervene. However, their clones arrived at the school and attacked them, leading the students to aid the ninja in their fight. Eventually, the evil ninja were defeated and the students were commended by Noble for their actions. At some point, Noble retired from being a principal at the school, becoming a tour guide at the Ninjago Museum of History for some time before finally becoming the warden of Kryptarium Prison, the prison for all the worst criminals.
Warden was present at the prison when the Second Serpentine War commenced, and Kapau and Chope broke in to capture Pythor. During the conflict, the prison's inmates were all freed but were soon put back in their cells by Noble and the guards. Shortly afterward, Noble would join the Elemental Masters in their fight at the Corridor of Elders.
When Nadakhan framed the ninja for crimes they didn't commit, Ronin captured them and they were locked away in Kryptarium Prison, with Noble leading them to their cells. During this time, Noble treated the ninja very harshly, disregarding their past actions and seeing them only as criminals. Fortunately, the ninja escaped the prison and set off to fight the Sky Pirates, the events of which were soon erased.
When the Sons of Garmadon were broken out by Harumi and Garmadon, Noble, being peaceful, tries to get them to leave, but they choose to make his prison their bunker before throwing him out. Later, upon Garmadon's defeat, Noble is reinstated as Warden.
The Tall Tale of Clancee (non-canon)
Noble was principal when Clancee attended the school, though expelled him due to his excessive pirate antics.
When Darkley's was transformed into a school for teaching good, the old teachers quit and Noble was hired to be the new principal. The students, however, despised their good teachings and rebelled. Due to their superior knowledge of the school building, the students succeeded in locking Noble and the teachers in one of the offices.
The ninja eventually arrived and were imprisoned as well. Noble explained the situation to them and aided in their search for a secret passageway out of the room. However, when they emerged from the passage, the ninja encountered their evil duplicates and the teachers decided to stay in the passage while the ninja sorted it out.
Once the evil ninja were defeated with the aid of the students, Noble applauded the students for converting to good and declared that a celebration was in order.
Noble lead a tour group at the Ninjago Museum of History, before noticing four kids leaving and asked for them to come back, unaware that they were the regressed ninja. Pretty soon, the Grundle appeared, scaring him and the kids into going back inside.
Master Wu eventually took over the boarding school and Noble became the warden at Kryptarium Prison. When the ninja arrived seeking to speak to Pythor, he confiscated their weapons and lead him to the Serpentine's cell.
When the ninja arrived at Kryptarium following them being framed for a crime spree, Noble personally escorted them to their cells, proudly pointing out that their vengestone chains rendered their powers useless. Upon arriving at the cell, Noble realized he had forgotten his keys and raced off to find them. He returned to find the ninja in confrontation with the Mechanic and ordered the two to shake hands and be friends.
When Dareth came to visit the ninja, Noble stood by as they talked. When Dareth informed the warden he would have to answer to the Brown Ninja should anything happen, Noble suggested that such a ninja might belong in Kryptarium as well.
When a fight broke out in the cafeteria later, Noble ordered the ninja to be taken to "The Hole" for starting it. This would prove to be consequential for the warden, however, as the ninja managed to escape.
When Garmadon was resurrected and broke Harumi out of the Ninjago City Police Station, they went to Kryptarium Prison, where they proceed to take over the entire prison and kick Noble out when he tries to make a deal with her, but is safely caught by the officers outside.
Noble is seen in one of the crossed out photos on the floor in Garmadon Tower when the Resistance broadcasts Lloyd's message to Ninjago, indicating Noble has been captured as part of Ultra Violet's Ultra Hunt.
Noble escorts Lloyd to a wing in Kryptarium Prison built specifically for Garmadon. After unlocking the entrance, Noble ran away and wished Lloyd luck.
When the ninja arrived at Kryptarium Prison to settle a riot, Noble explained two of the inmates had a dispute but were able to work it out prior to the ninjas' arrival.
After overhearing two guards talking about the ninjas' disappearance, Noble warned them to stop before the inmates get any ideas about escaping.
Noble patrols the cells at Kryptarium and taunts the newly recaptured Mechanic. The inmate warns him that a change is coming, which does come in the form of Unagami hacking into the prison's systems and freeing all of the prisoners.
Noble is an old man with short gray hair and a chin strip. He wears large glasses and has definitive cheek bones.
As a principal, Noble wore a white shirt with a bow-tie underneath a sweater and brown overcoat.
As a warden, Noble wears a black suit coat with gold buttons and small pockets over a white shirt and tie.
Noble is a passive person with a cheeky sense of humor, as he can often be found being intimidated by villains or teasing them as they sit behind bars. He has a strong sense of responsibility for his job and is capable of being strict to most inmates, regardless of their past. He's also somewhat forgiving, helping to celebrate the Darkley's students' good deeds instead of punishing them for locking him and the other teachers in a classroom.
- Alongside Patty Keys, Dareth, Fred Finely and Benny, Noble would be one of few Ninjago citizens seen in the show to change occupations over seasons.
- Prior to Season 8, he had the same hair as Cyrus Borg, which was an altered version of Obi-Wan's hair from Star Wars: The Clone Wars. As of Season 8, Noble has the same hair as Shade, which has cutouts for the ears.
- He has the same face as the Postman but without the mustache.
The images on Noble need to be organized.
