Kalmaar
King Kalmaar was the ruler of Merlopia and the Endless Sea , Trimaar 's son and Benthomaar 's adoptive brother. Due to his deep prejudice for those who lived on land, Kalmaar became obsessed with reawakening a sea serpent known as Wojira so he can use her powers to destroy the surface world. . As years went by, Kalmaar was still searching for Wojira until he once managed to find a sea scroll depicting the Temple of Wojira . With the help of his adopted brother, whom he used, he got to the temple, stole the Wave Amulet from his kind and began experimenting with models of the real Storm Amulet in order to reawake Wojira. . When he learned the position of the real Storm Amulet from Nya , Kalmaar killed his father and blamed it on the ninja so he could become king of Merlopia . After he became king, he went on a quest to find the Storm Amulet for his main goal. Once he did, he was able to reawaken Wojira and take control of her with his trident . However, during his assault on Ninjago City , Kalmaar was ultimately devoured by Wojira after Benthomaar destroyed his trident, which resulted in him losing control of the sea serpent. .
