“So the time comes at last. The time for which we have prepared all these years. Awaken the Stone Guardians. Let all know, invaders come. We must prepare to defend the amulet!”
— Mammatus to the Keepers, "The Storm Amulet"

Chief Mammatus is the current leader of the Keepers. Like the rest of the Keepers, Mammatus bore the responsibility granted by The First Spinjitzu Master of protecting the Storm Amulet, an ancient relic and the key to awakening Wojira. Deceived into thinking Wojira had awoken and was preparing to attack, Mammatus and the Keepers attempted to appease the beast, but to no avail. After apprehending the ninja, Mammatus planned to sacrifice Jay to the beast, but helped the ninja after they uncovered Ronin's falsification of Wojira. Following the battle, Mammatus realized the Storm Amulet was missing, but he and Nya quickly retook it from Clutch Powers.

Sometime later, the ninja face Kalmaar, who schemes to awaken Wojira. They return to Mammatus's island and explain the situation. Mammatus entrusts the ninja with protecting the Storm Amulet, but they quickly realize it's a fake, and the real one is in Clutch Powers' possession.

History[]

Prior to The Island[]

Mammatus assumed leadership of the Keepers and was committed to safeguarding the Storm Amulet. Prior to the arrival of the ninja on the Island of the Keepers, Ronin and the Kryptarium inmates constructed a ship designed to mimic Wojira, deceiving Mammatus and the Keepers into believing that Wojira had returned. In an effort to placate what they believed to be Wojira, the Keepers made sacrifices. Initially, they provided the criminals with money, but eventually resorted to offering fruits and other materials until Mammatus realized that a human sacrifice was necessary to appease the false Wojira.[1]

The Keepers of the Amulet[]

Upon receiving instructions from Mammatus, the Keepers successfully apprehended the ninja. Upon arrival in the throne room, Nya inquired about the motive behind the attack, to which Mammatus accused the ninja of theft. Mammatus emphasized that the Storm Amulet had always been protected by the Keepers, and that the ninja were not the first to attempt to steal it. When Jay expressed curiosity about the amulet, Mammatus disclosed that it had been taken from Wojira and that the Keepers had sworn to safeguard it for generations. Despite Zane's assurance that they had no intention of taking the amulet, Mammatus believed that the ninja had gained too much knowledge and therefore must be held captive indefinitely to ensure the amulet's safety.

The Gift of Jay[]

Mammatus ordered the imprisonment of the ninja except for one, who would be used as the ultimate sacrifice for Wojira. As a Keeper asked as to which ninja it was, to which Jay interjected, questioning the necessity of the aggressive behavior. Jay introduced himself politely, but Mammatus identified the Lightning Ninja as the chosen one to be the sacrifice.

Later on at the docks, Mammatus urgently addressed the Keepers, reminding them of their ancient duty to protect the world from the destructive force of Wojira like the First Spinjitzu Master tasked their ancestors. To calm her anger forever, the Keepers have prepared to sacrfice Jay, hoping he would appease her and return her to slumber.

The Tooth of Wojira[]

When Mammatus noticed that the ninja were freed from the poles, he and the other Keepers attempt to stop them from rescuing Jay, but failed to do so. After the ninja returned without Jay, Mammatus warned them of the dangers of angering Wojira, but Lloyd challenged the existence of the sea monster. He presented evidence of the con, revealing that the Keeprs had been tricked into offering sacrifices to a fake Wojira. Lloyd implored Mammatus to provide insight into the genesis of the Keepers' tradition, to which he disclosed that they had been bestowed with the responsibility of safeguarding the Storm Amulet from Wojira for millennia. Additionally, he expounded that upon suspecting Wojira's resurgence, the Keepers deemed it imperative to offer a human sacrifice as a means of appeasing Wojira indefinitely. Lloyd scold Mammatus about the decision to sacrifice Jay, to which Mammatus defended his actions as a command to protect the Storm Amulet at all costs. However, Kai pointed out that the cost of sacrificing Jay could potentially be detrimental to him, thus leaving the Keepers feeling ashamed. Lloyd instructed Mammatus to draw a map of the island's coastline so the ninja could track down the fake Wojira.

Mammatus expressed his apologies to the ninja for the unfortunate events that have occurred during their arrival. However, he was interrupted as he realized that the Storm Amulet was missing and was concerned about its whereabouts. He later joined Nya when she caught Clutch Powers trying to steal the amulet again.

The Storm Amulet[]

Mammatus was informed by the ninja that the Merlopians were in route to steal the Storm Amulet. In response, Mammatus immediately commands the Stone Guardians to be summoned, recognizing the need to prepare for battle. However, the ninja plead with Mammatus and urged them to reconsider his plan. They caution that the number of invaders was overwhelming and the only way to protect the Storm Amulet was to transport it far away from the island. Despite the ninja's warning, Mammatus firmly believed that the Island of the Keepers was the most secure location in Ninjago, as it was concealed for thousands of years by the storm belt. However, Nya interjected and mentioned that the Merlopians would be beneath the storm. Jay supports Nya's suggestion, emphasizing the relentless determination of Kalmaar to obtain the amulet. In light of the new information, Mammatus decided to entrust the sacred duty of protecting the amulet to Nya, passing on the mantle of the amulet's guardian. With a solemn oath, Nya accepts the responsibility. Mammatus then handed over the amulet to Nya, symbolizing the official transfer of guardianship. However, Zane discovered that the Storm Amulet they possessed was, in fact, a counterfeit. The revelation left Mammatus in a state of disbelief, questioning how such an error could have occurred.

Appearance[]

Mammatus has purple-pink radiant skin like the other Keepers, orange eyes, and large yellow straw-like teeth with one golden tooth. The symbols on his face are golden, unlike other Keepers. As the lines on the side of his body on his minifigure suggest, he is overweight, probably due to enough food as a chief. It is unknown whether he has hair or is bald, although Clutch Powers drew him without hair.[2] His body is covered with lavish golden armor with orange symbols, a dark orange image of Wojira on his belt, and many green glowing stones. His upper legs are also covered with armor and he has gold knee pads with green stones. He also wears a long vermilion cape and a large chief's crown made of gold on his head. Five green stones stick out of it, with another in the middle of the crown in front, round with the same symbol as on his throne. Two long white teeth are also stuck in the crown on the sides of the head.

Personality[]

Mammatus is committed to his duty to protect the Storm Amulet at all costs and is willing to use any means to protect it if it means success. He also seems to be relatively talkative, as he has explained everything about the amulet to the ninja, even though they just wanted to know which amulet he was referring to. He became a little more friendly when the ninja found out that Wojira was fake. He was even willing to hand over the amulet to Nya because he trusted her.

Weapons and abilities[]

Abilities[]

  • Storm: Like the other Keepers, Mammatus can create, generate, increase, absorb, conduct, shape, and manipulate electricity from his staff or the electrical storms from the storm belt, letting him redirect natural lightning in an electrical storm and use it to electrocute opponents.

Weapons[]

  • Lightning staff: As chief of the Keepers, Mammatus can handle his staff well, which he can blow up spinning and catch it again. However, he does not seem to be a very well-trained warrior, as although he was in a fighting position, the ninja easily defeated him and threw him to the ground.

Relationships[]

Keepers[]

“Keepers, hear me! Ahem. Long before time had a name, we were charged with protecting this world from the wrath of Wojira.”

Mammatus and PoulErik

PoulErik is Mammatus' second-in-command and friend.[3] He is often seen by the side of his chief and helps him. When the fake Wojira first appeared, he immediately ran after Mammatus to warn him.

Wojira[]

“We thought we had appeased her, but only a week later, she was back. Soon our treasures were gone, so we gave fruits and coconuts, whatever was left. But we needed something to placate Wojira forever. We needed an ultimate sacrifice!”
— Mammatus to the ninja, "The Tooth of Wojira"
LEGO Ninjago-TtoW-03-56

Mammatus with the Storm Amulet of Wojira

Although Mammatus had never seen Wojira alive, his ancestors were given the task by the First Spinjitzu Master to guard the Storm Amulet so that she could never wake up again. Mammatus continued in the role of his ancestors, and he had great respect and fear of Wojira. When she seemed to wake up, he sacrificed many of the things the Keepers had, including gold, wood, fruit, chicken, and man. He did all this to calm the Sleeper's anger and drive her back to sleep.

Ninja[]

Mammatus giving the amulet to Nya

When the ninja first reached the Island of the Keepers, they were noticed by the Stone Guardians and captured by the Keepers. Mammatus then imprisoned them, but when he noticed Jay, he immediately picked him, choosing him as the human sacrifice that would appeased Wojira forever. He was angrily angry when the ninja managed to escape, so he tied them to a totem pole on the beach so they could watch their friend's sacrifice. However, when he learned from the ninja that Wojira was a fake, he told them where something so big could be hidden and helped them. When Ronin and his allies were imprisoned, he thanked the ninjas and let them go. Later, when they returned to the island, he welcomed them as his friends and was willing to hand over the amulet to them when he found that he was no longer safe.

Ronin[]

We should send her a sacrifice of gold and gems to appease her!”
— An unknown figure to Mammatus, "The Tooth of Wojira"

Although Ronin never directly interacted with Mammatus, he was responsible for creating the fake Wojira and instilling in Mammatus the idea of sacrificing their valuables to her. When the ninja and Twitchy Tim defeated Ronin, Mammatus imprisoned him in their prison until he escaped or was released.
