Aspheera

Aspheera is the leader of the Pyro Vipers and a Serpentine sorceress.

History
In her youth, she forged a friendship with a young Wu in a bid to learn Spinjitzu and secretly overthrow Mambo V. After Wu used Forbidden Spinjitzu to defeat her, Aspheera was imprisoned in the pyramid for a millennium, after which she was accidentally freed by the ninja. She promptly stole Kai's element of fire, allowing her to reignite her forces.

Immediately, Aspheera swore revenge on Wu and sieged Ninjago City with a legion of Pyro Vipers and Elemental Cobras. Eventually, her rampage reached the Hangar Bay, where she attacked Wu and the ninja. Using the second Scroll of Forbidden Spinjitzu, the ninja were able to incapacitate Aspheera - but not before she banished Zane to the Never-Realm. Aspheera is currently incarcerated in Kryptarium Prison.
