The Emperor of Ninjago was the ruler of Ninjago City, the husband of the Empress and the adoptive father of Harumi. They were relatively private about themselves, even forcing Harumi to stay within the castle until they decided to speak out once crime continued to rise in spite of Lloyd Garmadon and his Ninja's efforts. He was killed during the Sons of Garmadon's attack on the Palace of Secrets during the theft of the Oni mask alongside his wife and Hutchins. Little did he know that his adoptive daughter was the leader of the Sons of Garmadon and she orchestrated the attack.
He was voiced by Richard Newman.
