The NINJAGO property resonates with kids and teens everywhere, with its three key components of ninja coolness, the application of mastery to life, and three dimensional characters that use the might of friendship as effectively as their weapons and elemental powers. The show balances epic action and emotion, interweaved with humour and adult themes that kids can identify with. The ninjas' adventures are all part of one big story over time, creating a rich world with characters that kids care about.
The four Ninja are snapped out of their post-hero complacency when Lord Garmadon's young+C4:C16 son Lloyd shows up and tries to pick up where his father left off. The Ninja dismiss him as a threat, but regret that choice after Lloyd wakes up the evil snake tribe. A prophecy is revealed that states a green ninja will ultimately defeat Lord Garmadon.
Back in training mode with the looming threat of Lloyd and the Hypnobrai, Zane wanders after a Falcon and lands himself in a heap of trouble. The rest of the Ninja leave the training dojo to help him and return to find that the snakes have burned it to the ground.
Lloyd, having been kicked out of the Hynobrai snake tribe unlocks a second tribe – The Fangpyres – to help him regain control. The Ninja are busy setting up their new HQ that Zane discovered, but are called to duty when the Fangpyres attack the village where Jay's family lives.
After the Fangpyres join forces with the Hypnobrai, Lloyd awakens Pythor – the last remaining snake of the Anacondrai tribe. Pythor lures Lloyd under his spell and steals a map from him that will show him where the remaining two snakes tribes dwell and Uncle Sensei saves Lloyd from doom.
Lloyd moves in and tries to make nice by helping out with chores, but he just gets in the way. Pythor has awoken the Vipoids and the Constrictaurs and an all out snake war has taken over Ninjago. The Ninja are not faring well, when a mysterious Samurai shows up and saves the day.
Pythor declares himself to be the destined leader who will reawaken The Great Devourer – an ancient beast who can't be killed and will consume all of Ninjago. We find out Nya is the Samurai and Lloyd is taken prisoner by the snake tribes.
When the four ninja follow the mysterious falcon into the woods, they stumble on a hidden work shop where Zane learns the secret about his past and in the process, finally knowing who he is, he is the first ninja to unlock his true potential.
Jay and Nya have to cut their first date in Mega-Monster Amusement Park short as the Serpentine are on their way to retrieve the first or four fang blades to be used to awaken the Great Devourer.
The four ninja go undercover as a dance troupe and enter a talent contest in their quest to win "The Blade Cup" where one of the fang blades is hidden.
The ninjas are suspicious when their arch enemy Lord Garmadon moves in to help searching for his missing son Lloyd - but realize they have to work together in their attempt to rescue Lloyd from the snakes inside the unstable Fire Temple that is built on a volcano.
