|“It's working. Send them all!”|
“All! You heard her! Go!”
|— Aspheera and Char|
|King Mambo||Mambo was the leader who led the Pyro Vipers during the time of the Olympics. He and the First Spinjitzu Master knew each other and agreed peace between Humans and Serpentine, meaning neither of the beings can cross over to their land. One day, Wu and Garmadon wanted to see the Serpentine Valley, and the treaty was broken when Wu trained Aspheera in Spinjitzu and used it for evil. Aspheera overthrew him with Spinjitzu, but she was defeated by Wu and Garmadon, restoring him to power, and sentenced Aspheera to magical entombment. It is unknown what happened to him after this.|
|Mambo's Advisor||Mambo's Advisor was the advisor who worked for Mambo the Fifth.|
|Aspheera||Aspheera is the current leader of the Pyro Vipers who learned Forbidden Spinjitzu but wanted to conquer Ninjago.|
|Char||Char is a servant of the Pyro Vipers working for Aspheera.|
|Elemental Cobras||Elemental Cobras are made from fireballs. Aspheera used them to destroy New Ninjago City/Ninjago City.|
|Fire Fang||The Fire Fang is the blue-black giant snake, the tall one Aspheera rides on.|
|Pyro Destroyers||Pyro Destroyers are destructive destroyers of the Pyro Vipers.|
|Pyro Slayers||Pyro Slayers are destructive slayers of the Pyro Vipers. Unlike Pyro Destroyers, Pyro Slayers do not have armor.|

Aspheera and the Pyro Vipers were resurrected again.
Aspheera controlled a model of Isla Sorna with real dinosaurs that the Ninja were trapped in.
In the episode, Aspheera told the Ninja if they gave her a return note in the House of Sorna, they can go free. In the book, Aspheera told the Ninja if they gave her the Heart of Sorna, they can go free.
Aspheera ordered Char to send out the Pyro Vipers to destroy the Blizzard Samurai.
