A Lesson in Anger

A Lesson in Anger is the two hundred and first episode of Ninjago: Masters of Spinjitzu, and the twenty-first episode of season fifteen.
==Plot==
Cole's Dragon Cruiser becomes inoperable during the battle with the Vengestone Army, but is saved by the timely arrival of Nya in the Destiny's Bounty. She takes the Ninja back to the Samurai X Cave, where they are unpleasantly surprised to find Garmadon. Wu explains their discovery of the Oni Form and his hopes that it may be able to defeat the Vengestone Army, and Garmadon agrees to instruct Lloyd. However, his teaching methods leave much to be desired, until an offhand comment makes Wu wonder whether there might exist a "Dragon Form" that they might unlock instead with help from Misako.
In Ninjago City, Gayle Gossip continues to report on the Vengestone Army invasion, while Mayor Trustable holds a press conference. Despite his own obvious preparations to flee, the mayor encourages the citizens not to panic, but soon changes his tune when the New Ninja are turned into crystal zombies. Back at the Samurai X Cave, Garmadon and Lloyd are both frustrated by the lack of progress in their "training", and Lloyd unlocks his Oni powers in anger only to quickly cease out of fear. The other Ninja come to Lloyd's defense, and Pixal then provides a way for them to face the Overlord's army the old-fashioned away: with upgraded vehicles.
Pixal explains that the Crystal King Temple will now provide a power boost instead of draining their power, but that they must be careful how they use it or risk damage to their vehicles. The Ninja eagerly set out, while Garmadon dismisses this expedition as hopeless.
