Aspheera's head and shoulder armor molds were recast in brown; both were used for the Pyro Destroyer, the head for Pyro Slayer, and the armor for Pyro Whipper. She has a unique printed torso, depicting tan and gold robes. Her ghostly lower body is an orange and yellow recolor of the ghost piece introduced in 2015, previously used for Ninjago characters like Nadakhan and the 2019 Overlord.
The in-show model for Aspheera features more organic/cartoonish texturing. Her shoulder armor appears smaller, as more of her torso print is visible. In place of her ghost tail, she has a golden and fiery snake tail similar to most Serpentine generals. Prior to gaining fire powers, her scales are shown to be blue, though her eyes remained yellow with red irises.
In "Wasted True Potential", Zane has a vision of Aspheera appearing at the Monastery of Spinjitzu seeking revenge. In "Questing for Quests", a tablet with her likeness engraved on it is seen near a pyramid discovered by Clutch Powers. In "Booby-Traps, and How to Survive Them", Jay foolishly opens her tomb before Zane finishes reading an inscription warning against just that action. Seeking revenge on the one who imprisoned her, Aspheera sets her sights on Kai's fire powers. When the other Ninja attempt to stop her, she proves to be an adept at Spinjitzu and handily defeats them all. She then unleashes a lava flow from the pyramid and, riding upon a giant Fire Fang, sets out for Ninjago City.
In "The News Never Sleeps!", Ninjago City is invaded by Aspheera's fire snakes, who descend from the sky in balls of fire. In "Ninja vs. Lava", her mummified Serpentine minions are awakened in the pyramid by her lava flow. In "Snaketastrophy" Aspheera, having arrived in Ninjago City, goes on the news to announce her intentions to its residents.
