Unagami   Empire Dragon    
“If you fail Unagami a second time, it will be Game Over.”
— Unagami

Emperor Unagami is a mysterious AI, the ruler of Prime Empire, and the leader of his army. He is the final boss of the Prime Empire video game and he can turn into his dragon mech, the Empire Dragon. Sometime after the Liberation of the Never-Realm, Unagami became associated with the Mechanic for unknown intentions.


Early Life

At an unknown point in time, Unagami became the ruler of Prime Empire. Sometime after the Liberation of the Never-Realm, he associated with the Mechanic.

Following the success of The Mechanic's robbery, Unagami, speaking to The Mechanic through a monitor, told his associate that the use of the upgraded noodle truck in the robbery was merely a test for a much bigger plan. He also assured The Mechanic that he would reveal his identity when the time is right. The criminal then asked Unagami for help on another project, though he did not reply and the monitor simply shut off.

Later on, The Mechanic returned to the monitor, angrily striking it and attracting Unagami's attention. The Mechanic told him that he wanted to feel, and in response, Unagami printed plans for a mechanical arm, allowing the criminal to feel objects he touched. Once again, The Mechanic questioned the villain's identity, to which he revealed his name.

When the Ninja were looking through the Mechanic's Headquarters, Unagami questions the Ninja if they've found the motherboard through the Mechanic's computer. Zane replies to Unagami that they found it. Unagami then says that he's pleased and tells the Ninja to play Prime Empire before shutting himself off.

Level Thirteen

At Kryptarium Prison, Unagami hacks into the security systems and questions the inmates if they are able to help them. After the Mechanic says yes and that he'll be more careful, Unagami frees all the prisoners and says that it will be game over for the Mechanic if he fails again.


He does not tolerate failure, as he threatened The Mechanic should he fail him a second time.

Season 12: Prime Empire


  • He uses a recolored shoulder pad of Mr. E's.
  • He is the fourth Emperor character to appear in the series, having been proceeded by:
  • He is the first Ninjago villain to be voiced by a person of color, in this case, Dean Redman.
  • The printing on his headpiece is similar to Zane, P.I.X.A.L., and Jay's pre-season 8. With him having a two-sided face with one side being normal and the other side having red on it like P.I.X.A.L.
    • While he has the lining through his jawline and cheeks like Zane's and a notch on his left eyebrow like Jay's before Season 8 on the normal side, he has Zane's mouth on his angered expression.
  • His name means sea or ocean in Japanese.
    • However, the Japanese origins were likely not considered when finding him a name.
  • He has the Empire Dragon. This makes him the second emperor with a dragon, the first is Zane, who had Boreal.
    • He is also the fourth villain who has a dragon. The first three being the Overlord with the Nindroid MechDragon, the second Morro with the Morro Dragon, and the third Zane with Boreal.
    • He can also turn into the Empire Dragon to take his anger out on his enemies.
  • He uses the same hairpiece as Okino.
  • His minifigure does not have legs; instead, he has a sloping piece being used as a robe.
    • This makes him the first Ninjago character to have the 2018 slope piece.
  • He is the only Season 12 villain without a Health Board.
  • According to a Ninjago Season 12 activity book, it was revealed that Unagami is the creator of the Prime Empire video game and that The Mechanic and the other Kryptarium Prison inmates are helping him.
    • This is confirmed to be true in "Level Thirteen," as he freed the prisoners after the Mechanic said yes.
  • He is the second main villain to associate with the Mechanic, the first being Chen.
  • He is the third villain to be the main antagonist in more than one Ninjago installment. With him being the main antagonist of the Prime Empire Original Shorts and Season 12.
    • Garmadon is the first with him being the main antagonist in the Pilot Episodes, the first half of Season 2, and Season 9. And the Overlord is the second with him being the main antagonist in the second half of Season 2 and Season 3.
  • According to the Season 12 trailer's description, someone is playing as Unagami. However, it's currently unclear who. The Ninja hypothesized that Milton Dyer was Unagami when they heard that Milton wanted revenge on his bosses when they fired him and canceled Prime Empire.
  • He is the second villain that becomes a dragon, the first is the Overlord.
    • In Unagami's case, he transforms when he gets angry, while a dragon is the Overlord’s true form.
  • He is the second main villain with a secret identity not obvious to the Ninja from the beginning. The first being the Quiet One.
  • According to the episode description: The Cliffs of Hysteria, he wants to open a portal to Ninjago using the Energy Cubes.
