Wojira
Wojira (also known as Wohira , the Sleeper in the Deep , the Great Serpent , or the Mighty Serpent of the Wave and the Storm ) was a storm spirit in the form of a giant sea serpent. Before time had a name, she possessed two amulets that gave her complete power over the seas of Ninjago during an ancient era of turmoil. In a battle with the islanders , Merlopians , and the First Spinjitzu Master , Wojira was defeated by Nyad and thrown into a deep sleep. . However, after being reawakened by Kalmaar , he used his trident to exercise his will on her body. Wojira helped Kalmaar with his goal of destroying the surface-world of Ninjago and its inhabitants until the king's trident was broken by Benthomaar , freeing her, upon which she promptly ate the Merlopian king. Before she could do further harm to Ninjago City , she was defeated by Nya who destroyed the Wave Amulet , although it is unclear whether she died or transported herself elsewhere to fall into another deep slumber and return.
