“Sorry I had to confiscate your weapons. Here we try to foster what I call 'an environment of encouragement.'”
Warden Noble to the Ninja, Wu and Garmadon in "The Greatest Fear of All"

Kryptarium Prison is a large facility that houses many convicted criminals. Located in the Sea of Sand and operated by Warden Noble, Kryptarium contains some of Ninjago's most dangerous culprits, such as several Skulkin, PythorSoto, a Giant Stone Warrior, Nindroids, the Ninja (formerly, in an erased timeline), the Sons of Garmadon, Aspheera, and formerly Lord Garmadon himself.

During the Second Serpentine War, the Ninja went to Kryptarium to find Pythor, who was the sole means of allowing Chen's army to be Anacondrai permanently. While there, a fight soon broke out when Kapau and Chope raided Kryptarium. The Ninja battled the Anacondrai warriors as well as many inmates before Pythor was ultimately captured. Sometime later, the Ninja were framed for a series of crimes they didn't commit and were imprisoned in Kryptarium. They then allied with Captain Soto, who helped them escape. After Jay made his final wish, Soto was put back in Kryptarium and the Ninja were never imprisoned there, to begin with.

After the Sons of Garmadon resurrected Lord Garmadon, they were arrested and put in Kryptarium. However, after Garmadon freed Harumi, she freed her allies and took over the prison. That night, Garmadon fought and defeated Lloyd in a brutal battle that took place in Kryptarium.

After Garmadon's takeover of Ninjago, the Sons of Garmadon used Kryptarium as a place to send anyone who opposed Emperor Garmadon. Those who got caught were Ronin, Police Commissioner, Simon, Tommy, Noble, Karlof, Neuro, Tox, Griffin Turner, Paleman, P.I.X.A.L., Misako, and Bolobo. Those who didn't get caught were Lloyd, Nya, Skylor, Dareth, Mistaké, and the Postman. They later broke out upon hearing the Ninja return and took it back, sending the Sons of Garmadon and Garmadon himself back to Kryptarium.

Shortly after Garmadon's defeat, a maximum-security cell was built somewhere in Kryptarium Prison, which was created for the sole purpose of imprisoning Garmadon. Later, after the Oni invade Ninjago, Lloyd and the Ninja reluctantly agree to free Garmadon so he can help them stop the Oni.

When the Ninja defeated Aspheera, she was imprisoned in the maximum-security cell they formerly used for Garmadon.

After the Ninja were banished to the Never-Realm, The Mechanic and Ultra Violet escaped only to be recaptured, along with Fugi-Dove, by P.I.X.A.L.

However, the Mechanic was able to escape again but was recaptured before Unagami hacked into the security systems and freed all the prisoners.


At some point in time, prior to the defeat of the Overlord, Kryptarium Prison was built to house Ninjago's most dangerous criminals, and at the same time, rehabilitate them as well.

Noble would eventually quit his principal job at Darkley's Boarding School for Bad Boys and become the prison's warden, becoming dedicated to the rehabilitation of the prisoners.

The Greatest Fear of All

In an attempt to figure out a weakness of the fake Anacondrai, the Ninja visited Kryptarium in order to interrogate a shrunken Pythor. However, the prison was infiltrated thanks to the efforts of Kapau'rai and Chop'rai, and several of the inmates escaped thanks to No-Eyed Pete using a fallen staff to open all of the cell doors. However, with the help of the Ninja, the inmates were all detained, save for Pythor, and the prison was eventually repaired.

The Corridor of Elders

Cole went to Kryptarium to ask the inmates to help them defeat Chen's Anacondrai army.

Shadow of Ronin (non-canon)

Shortly after Ronin stole the Ninja's memories, he sent his goons to Kryptarium to get the map to the Inky Lemonberry from Hibiki. However, the Ninja soon arrived seeking Hibiki's help as well and sent the goons in retreat.


After being captured by Ronin, the Ninja were sent to Kryptarium, and due to their powerful status, were detained in the section for the most dangerous criminals. There, they were confronted by several angry inmates, including the Mechanic. However, the prisoners were quickly placed into their cells, and at lunch, the ninja managed to learn from Soto the weakness of a Djinn; the Tiger Widow venom. Following a brief skirmish with the inmates, the Ninja agreed to help Soto escape the prison in return for the location of Tiger Widow Island.

As a result of Jay's final wish erasing the events of the season, Kryptarium regained its escaped convict, Soto. Some time afterward, Frakjaw later escaped his imprisonment.

Dark Island Trilogy, Part 3

After being defeated by the Ninja at the Temple of Light, the Sky Pirates were sent to Kryptarium Prison for several crimes such as kidnapping and attempting to plunge Ninjago into darkness.

Dread on Arrival

Following their defeat, Harumi and several members of the Sons of Garmadon were arrested by the Police Commissioner. They were then taken to Kryptarium Prison for their actions.

True Potential

Harumi and a resurrected Garmadon broke into Kryptarium and took it over, freeing the Sons of Garmadon. Garmadon used the basketball field to practice on a few members. Harumi later had the cameras broadcast the fight between Lloyd and his father to Ninjago.

Two Lies, One Truth

Two members of the Sons of Garmadon guarded the prison after several members of the Resistance were captured.

Green Destiny

When Chopper Maroon informed the guards they need all hands on deck because the original Ninja and Wu were back, Karlof managed to break Ronin, Griffin, and himself out to help break the other prisoners of Ultra Hunt out. After taking the prison back and Garmadon lost his power, the Sons of Garmadon were sent back alongside Garmadon.

The Weekend Drill (flashback)

While Cole was fighting the Giant Stone Warrior, he inadvertently knocked him into Ultra Violet and Killow's cell, the latter coming out, supported by the other prisoners, and teamed up with the Giant Stone Warrior, only to get knocked back into his cell.

The Darkness Comes

Lloyd goes to visit his father, who is in a very special solitary confinement cell in a high-security wing built for the single purpose of imprisoning Garmadon. He demands to be released for the upcoming threat, but Lloyd refuses. He later comes back with the others when the Oni attack Ninjago and accept his offer to release him.

Questing for Quests

While the Ninja are in the Police Commissioner's office trying to find a quest, Jimmy comes in to report on a riot in Kryptarium. The Ninja rush to the scene only to be a recording of the fight. While there, they visit Killow to see if he has any evil schemes, but they bored away when he shows the Ninja his painting.

Vengeance is Mine!

After her defeat by the Ninja, Aspheera is arrested and locked away in Garmadon's old cell of the prison. She is visited by Wu and she tells him that Zane was not killed but banish to another realm.

The Absolute Worst

While incarcerated, The Mechanic learns of the Ninja leaving, and relays it to Ultra Violet before they conspire to break out of Kryptarium, joined by self-proclaimed villain Fugi-Dove, only to be recaptured by P.I.X.A.L., who installed sensors in case of prison escapes.

Level Thirteen

As Noble inspects the prisoners in their cells, Unagami soon hacked into the security system and opened all the cell doors before The Mechanic has some of the prisoners, including Captain Soto and Ultra Violet, come with him, rejecting Fugi-Dove's request at the same time. The prisoners head to Borg Tower, where The Mechanic had planned to enter Prime Empire at, however, the prisoners were stopped by the Ninja, who entered the game, besides Zane and P.I.X.A.L., who escaped the tower with Cyrus Borg and the Prime Empire Motherboard, leaving the prisoners behind.

It is presumed that all the inmates were recaptured afterward.


Prisoners of Ultra Hunt (all formerly)



  • Original concept art depicted Kryptarium as being constructed on the top of the mountain.
  • Kryptarium's design is based on a panopticon prison.
  • It is unknown what happened to the prisoners when Harumi and Lord Garmadon took it over in "True Potential." They may have simply been off-screen or escaped.
  • Approximately, over 58 prisoners have been in Kryptarium (never all 58+ at once). This includes all the other generic prisoners and Squiffy, in an alternate timeline, where the Comissioner can be seen putting him in a police car in "Operation Land Ho."
  • As of Season 8, most of the inmates no longer wear prison jumpsuits. The reason for this is unknown but was likely done for the fans to easily recognize the characters or to save on production costs by not having to render new models for each inmate.
  • Garmadon was imprisoned in a very special solitary confinement cell that is only accessible by Noble's eye iris and a retractable bridge.
  • In the original end of Season 7, Acronix and Krux would have been locked up in Kryptarium Prison.
  • In "Level Thirteen," Unagami hacked into the security systems and freed all the prisoners.
    • It is unknown if this affected Cell One as well.
  • According to Tommy Andreasen, the Sky Pirates aren't shown in Kryptarium Prison in the series, as it would confuse people who hadn't read the Dark Island Trilogy.[1]
  • Some parts of 70591 Kryptarium Prison Breakout resemble the outside of Kryptarium Prison, in the series, like:
    • The roof. In both, the show and the set, it has the red 'blades'.
    • The gate. In both, the show and the set, the gate's in the middle of the prison. But in the show, the gate is black and gray. In the set, it's red, white, black, and has a dragon pattern on it with a key hole and two 'scythe blades.'
    • The levels. The show makes it have multiple layers, and the set does. The set makes it have two, not including the roof.
  • The Mechanic is the prisoner who escaped from Kryptarium the most times. He ran away before season 8, during season 11, after season 11 and during season 12.
