“Others have come before you. Others have tried, and failed. For we uphold our vow. We are the Keepers of the Amulet.”
— Mammatus to the ninja in "The Keepers of the Amulet"

Chief Mammatus is the leader of the Keepers.

History

Prior to The Island

At some point, Mammatus became the leader of the Keepers, and was devoted to protecting the Storm Amulet. Prior to the ninja's arrival on the island, Ronin and the Kryptarium inmates created a ship intended to impersonate Wojira, fooling Mammatus and the Keepers into believing Wojira had returned. To appease what they believed was Wojira, they performed sacrifices. At first, they gave the criminals money, but then started to give them fruits and other materials until Mammatus realized that the Keepers needed to sacrifice someone to appease the fake Wojira forever.[1]

The Keepers of the Amulet

Mammatus instructed the Keepers to capture the ninja, doing so successfully. When the ninja arrived at his throne room, he believed that the ninja were thieves seeking to steal the Storm Amulet. He explained the history of the Storm Amulet and their sacred oath about protecting it. Soon, he then declared the ninja prisoners.

The Gift of Jay

After Mammatus told the ninja that they will forever be his prisoners, he told the Keepers to take the ninja away. But when Jay introduces himself, Mammatus tells the Keepers to take Jay somewhere else.

Later on, when the Keepers were done placing Jay on one of their boats, Mammatus makes a speech to the Keepers about Wojira and the First Spinjitzu Master, and that they will sacrifice Jay to Wojira so they can keep her submissive.

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, he berated them for awakening Wojira. However, he then realized that Wojira was a fake, and explained the full history of how the Keepers gave tribute to a fraud. Wanting to redeem themselves, they gave a map of the coastline.

Later on, Mammatus apologized to the ninja for his acts. He realized the Storm Amulet was missing and was with Nya when she caught Clutch Powers trying to steal it again.

Official description

Character Encyclopedia New Edition

Mammatus is the latest in a long line of island leaders sworn to protect the Storm Amulet. This powerful artifact was given to his ancestors by the First Spinjitzu Master before Ninjago Island even existed. Like all Keepers of the Amulet, he tries to look tough as possible to outsiders!

Island Attack!

Chief Mammatus is the head of the islanders! This high office is handed down in his family. If the Storm Amulet disappears from his island, it could end badly for his keepers - and for himself!
