Aspheera is the former leader of the Pyro Vipers and a Hypnobrai sorceress. In her youth, she forged a friendship with the 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 millennia, after which she was accidentally freed by the ninja. She promptly stole Kai's element of fire, allowing her to resurrect her forces as Pyro Vipers. Immediately, Aspheera swore revenge on Wu and sieged Ninjago City with her army. 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 was then taken to Kryptarium Prison and held in cell one, Lord Garmadon's old cell. Sometime after, the ninja freed Aspheera from prison in request to return Nya back to her human form by stealing her elemental powers with her staff. After she succeeded, she returned to the pyramid she was once imprisoned in, before she was invited to join the Council of the Crystal King and exact her revenge on those who wronged her. During the battle against the ninja and the Resistance, Aspheera was frozen by Zane, following her defeat at the hands of Kai.Aspheera is a female Serpentine who has yellow eyes with red-orange irises and looks like an Indian cobra, similar to King Mambo. Her body is covered in dark teal scales and has a tail instead of legs. Her arms are the same teal color with silver gloved hands. She wears a unique tan and gold robe under a golden cuirass with Indian Cobra head-shaped shoulder pads. When empowered with Kai's Elemental powers, she had golden scales, a flaming cobra hood, and a fiery golden tail. When empowered by the Overlord, her hood turns into pink-purple crystals, her eyes became pink with light gray irises, and her scales changed to dark gray. She also wears the same Crystal Council armor, consisting of purple sleeves, metallic gray torso with purple and glowing pink accents, and the Overlord's symbol in the center. When she was young, she had a regal gold and black bee-like marking on her forehead, her eyes were red with dark red pupils like all the other Hypnobrai, and she did not have her cuirass on. Originally, in her youth, Aspheera is charming yet very manipulative, cunning, and arrogant. She is also power-hungry as she overthrew Mambo V for the sake of creating her own empire to conquer all of Ninjago. Having spent millennia imprisoned, Aspheera desired total revenge on Wu for deceiving her and allowing her to suffer this fate, proving herself to be somewhat hypocritical as she deceived Wu for her own selfish purposes. Befitting her power, she is hot-headed and very impatient, as shown when she knocked down some artifacts while looking for the Scroll of Forbidden Spinjitzu and when she snaped at Char for asking her who the "Treacherous Deceiver" is. Unlike most villains, she didn't seek to rule Ninjago, as she did before when she disregarded conquering what she thought were weak. After her defeat, she was composed at meeting Wu again and only remarked on the circumstances. She showed herself willing to settle for defeat since she was aware that her actions distressed Wu at not getting Zane back from the Never-Realm, where she intended to trap Wu. She seems to have become somewhat mentally unstable during her imprisonment in Kryptarium Prison, and her desire for revenge has multiplied, forcing her to repeat the word whenever revenge is mentioned, laughing devilishly as she does so. Aspheera also felt betrayed by everyone around her, so she was very surprised and shocked when Lloyd kept his promise to show her the way out of the hangar bay if she drained Nya's powers. Even after the ninja broke her out from prison and allowed her to be free after helping return Nya back to her human form, Aspheera was still willing to betray them and join the Council of the Crystal King
