Ninjago powerless bio and trivia

The ninja rush to the Ninjago museum of history to recover a dangerous scroll before it falls into the hands of the serpentine sorceress, Aspheera
Reeling from the loss of his powers, kai tells the other ninja that he will sit out the battle. He fears in his present condition that he will just be a burden. The ninja reluctantly part wars with Kai and run to the museum to confront Aspheera. A little boy who witnessed the conversation tries to get Kai to go after them, but Kai refuses. He tells the kid to forget it, whereupon the kid runs after the ninja on his own. Fearing for the boys safety, Kai runs after him. Meanwhile, at the museum, the ninja battle Aspheera and her newly resurrected servant, char, for control of the first scroll of forbidden spinjitzu. When Lloyd accidentally touches the scroll he immediately becomes more powerful. But the sudden influx of power distracts Lloyd and Aspheera gets the better of the ninja. She takes the scroll and exits, leaving her pyro vipers to destroy the ninja. At the last moment, however, the brave kid arrives and tried to stop the serpents. Just as the serpents are about to attack the boy, Kai bursts onto the scene in all his heroic glory and takes out the bad guys, saving the ninja and the little boy, all without any powers
