Rise of the Snakes

Peace has come over Ninjago, and the Ninja are taking a break from training to play video games. After being scolded by Sensei Wu, Nya comes running in, announcing that Lord Garmadon had returned and was spotted heading to Jamanakai Village. The Ninja rush off and fly there on their dragons. When they arrive, the supposed "Lord Garmadon" was actually Lloyd Garmadon, his son. Lloyd tried to steal the candy from the village, but the Ninja stopped him. As the Ninja head back to the Monastery, Lloyd accidentally stumbles upon the ancient Serpentine tomb of the Hypnobrai. Slithra, the Hypnobrai general, accidentally hypnotizes himself and Lloyd controls him. Back at the monastery, the Ninja tried to have a tournament to ser who was the destined Green Ninja, bit Kai almost sets the place on fire with his sword. The sensei scolds the Ninja, and Lloyd takes over Jamanakai Village where Nya is at the moment. The Ninja rush off to save her and find the entire village was hypnotized by the snakes. The Ninja fight and the snakes retreat, except Skales who partially hypnotized Cole. The Ninja and Nya, along with Sensei, head back to the monetary to train against Lloyd and the Serpentine.

Home

Back in training mode with the looming threat of Lloyd and the Hypnobrai, Zane wanders after a Falcon and finds Lloyd's new base (a playhouse he commanded the hypnotized leader to build). The Ninja succeed in destroying the base, though they are nearly thwarted by a hypnotized Cole. They are only saved by Sensei Wu's use of the ancient Sacred Flute, used to drive the Serpentine underground, to break Cole's hypnosis. But then the Hypnobrai leader is defeated by his treacherous second-in-command Skales, who steals back the staff, sends Lloyd away, and destroys the Monastery. Homeless, the Ninja are guided by the Falcon to a wrecked ship, the Destiny's Bounty.

Note: First Appearance of The Bounty

Snakebit

Lloyd unlocks a second tribe - The Fangpyre - to help him regain control and have his revenge on the Hypnobrai. The Ninja are busy cleaning and setting up their new HQ aboard the Destiny's Bounty with modern features, but are called into duty when the Fangpyre attack the junkyard where Jay's parents, Ed and Enda, live. The Ninja, especially Jay, must rush to save the pair from the transforming venom of the Fangpyre...

Never trust a Snake

After the Fangpyres join forces with the Hypnobrai, Lloyd releases Pythor - the last remaining snake of the Anacondrai tribe. Pythor, pretending to be his friend, steals a map from him that shows where the two remaining snakes tribes dwell. Sensei Wu then takes Lloyd under his wing.

Note: First appearance of Pythor.

Can of Worms

Lloyd moves in and pranks all the Ninja, turning Zane's suit pink. Meanwhile, Pythor has awoken the Venomari and the Constrictai and plans to unite them under him. In the process, he steals the Sacred Flute. The Ninja go and foil the plan for unity, but are nearly captured. It is only Zane's pink suit that enables them to escape with their mission complete.

The Snake King

After finding the ancient Serpentine city of Ouroboros, Pythor, through a devilish trick, declares himself to be the Snake King, the destined leader who will reawaken The Great Devourer - an ancient, seemingly immortal beast who will consume all of Ninjago. Lloyd sees this, but is discovered and made prisoner. The Ninja, captured by the Serpentine while trying to rescue Lloyd, are saved by Samurai X, a mysterious warrior who fights against the Serpentine, and Kai makes a shocking discovery about his sister...Nya is the samurai!

Tick Tock

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; he is a nindroid designed to 'protect those who cannot protect themselves'. He becomes the first Ninja to unlock his true potential.

Once Bitten, Twice

Jay and Nya have to cut their first date in Mega-Monster Amusement Park short, as the Serpentine arrive to retrieve the first of four fang blades to be used to awaken the Great Devourer. But Jay pricks his hand on the fang of a skeletal Fangpyre, triggering a transformation... Jay finds his true potential in this episode.

Royal Blacksmiths

The four Ninja go undercover as a dance troupe and enter a talent contest in their quest to win “The Blade Cup”, in which one of the fang blades is hidden, taken from its tomb by Clutch Powers. During this, Cole meets his father, the leader of one particularly famous dance troop, who, if anything, is bossier than Sensei Wu. At once point, Cole contemplates stealing the cup, but is berated by his father and decides to make him proud by performing and winning the cup. Cole, saving his father when Pythor collapses the stage while stealing the cup, finds his true potential.

The Green Ninja

The Ninja are suspicious when Lord Garmadon, brought by Sensei Wu from the realm of darkness he fled to, moves in to help searching for his missing son - but realize they have to work together in their attempt to rescue Lloyd from the Serpentine while they dig for the third Fang Blade in the heart of the Fire Temple. Kai, after being held back by his ambition to become the Green Ninja, reaches his true potential and rescues Lloyd. It is also revealed, though Kai's own realization, that Lloyd is the destined Green Ninja. This causes grief to both Wu and Garmadon, since their family has now been further divided.

All of Nothing

At a suggestion from Lloyd to steal back the three Fang Blades as Pythor goes for the fourth, the Ninja and Sensei Wu try to infiltrate the Serpentines’ inner sanctum and walk right into a trap. When Lloyd’s rescue mission fails, there is only one person who can help them, namely Lord Garmadon. In the nick of time, Garamadon comes with the Skeleton Army and they engage in a battle against Pythor and the Serpentine, allowing Lloyd to release the Ninja and get the Fang Blades. Garmadon leaves Lloyd to follow his own path and the Ninja to destroy the Fang Blades, but Pythor follows them in secret...

The Rise of Great Devourer

Upon arriving at Torchfire Mountain, where the Fangblades can be destroyed, Pythor reveals himself and steals the blades back, leaving the Ninja to die. The four, with Wu, Nya (Samurai X) and Lloyd, haste to the lost city of Ouroboros to try to stop Pythor from awaking The Great Devourer, but it is a race against time. After a battle on a Serpentine Truck-fortress, in which Sensei Wu deliberately cuts himself off from the Ninja, all arrive at the city. At last, Pythor succeeds, but Sensei Wu follows him and forces him to see the power he has unleashed. They are then both consumed by the awakened Great Devourer.

Day of the Great Devourer

Disaster threatens as the Ninja must fight to defeat the all consuming Great Devourer in a desperate attempt to save Ninjago. In the end, only Lord Garmadon, using the Four Golden Weapons, can destroy the Devourer. The snake is destroyed and Wu is shown to have survived, but Lord Garmadon vanishes with the Weapons and Lloyd must accept the fact that he must face him one day...

Note: This is the Great Devourer and Pythor's final appearance.

Darkness Shall Rise

The ninja are helping in fixing Ninjago City after the Great Devourer was defeated. Nya informs them that she has found a real-estate agent named Patty Keys who will help them find a place to live. Nya and Sensei Wu than leave to find parts for the Ultra Sonic Raider. Sensei also reminds the ninja that their new mission is to train Lloyd. Meanwhile, Skales along with the other snake-tribe generals attempt to regain the trust of the Serpentine after Pythor’s defeat. However, Lord Garmadon persuades what remains of the Serpentine Army to follow him, and recreates the remains of Destiny’s Bounty into a ship he names “The Black Bounty”. In the meantime, Patty Keys finds an apartment for the ninja called the “Hero Suite” with a training-room suitable to train Lloyd. The apartment is expensive, so the Ninja decide to get jobs to pay for the rent, with Cole as a bank security officer, Jay a pizza delivery man, Kai a child entertainer, and Zane a sushi chef. This goes well in the beginning, but then turns out not so favorable. After stopping the Generals from kidnapping Lloyd and having Skales arrested, they settle for the lower-class flat. Meanwhile Lord Garmadon and the Serpentine fly to the Golden Peaks – birthplace of the Golden Weapons - and fuses the Weapons together into a Mega Weapon. He plans to use it to destroy Sensei and the ninja so they will never be able to train Lloyd, then the prophecy will never be fulfilled…

Note: First appearance of the Mega-Weapon.

Pirates vs Ninja

The Episode begins a few centuries ago, with the pirate crew of the Destiny’s Bounty led by Captain Soto looking for the 'Island of Darkness'. The crew leaves No Eyed Pete to steer the ship when the captain wasn’t noticing, but due to his lack of sight the ship crashes. In the present time, the ninja are training Lloyd in their smaller and more affordable apartment, but looking for a better place to train. On the Black Bounty, Lord Garmadon is discussing the Mega Weapon with the snake-generals, and he tries to use it to destroy the Ultra Dragon, who happens to be flying by. He is outraged when he is unable to destroy the dragon, but discovers Captain Soto’s journal in the ship’s cabin and accidentally resurrects the pirate-crew using the Mega Weapon. Meanwhile, the Ninja find “Grand Sensei Dareth’s Mojo Dojo”. Dareth agrees to let them use his dojo if they defeat him in a battle. Of course they do, and Dareth allows them to use his Dojo. In the meantime Lord Garmadon realizes that the Mega Weapon does not have the power to destroy, only to create, and it also drains his strength every time he uses it, so he needs time to recover. The pirates lock up Garmadon and the snakes. The Ninja start training Lloyd at the dojo, where he demonstrates his extraordinary talents. The Pirates then attack Ninjago City, taking all the money they can get. Sensei Dareth, dressed as the Brown Ninja, jumps on ship but gets captured by the pirates. The ninja go to his rescue, and while battling the pirate captain, Lloyd unlocks his Spinjitzu the first time. The pirates are later arrested, and Lord Garmadon takes back the Black Bounty…

Double Trouble

On board the Black Bounty, Garmadon and his Serpentine Army brainstorm ideas to destroy the Ninja while still using the Mega Weapon's power of Creation, which mostly results in individual Serpentine being thrown overboard. Garmadon, after seeing his own reflection in the Mega-weapon, creates four dark versions of the Ninjas, and sends them to destroy the Ninja. Meanwhile, Jay is trying to teach Lloyd to harness the power of Lightning, when they get word of a ceremony at Darkly's School for "Great Students". But it turns out to be a trap, as the boys kidnap the Ninja and try to turn Lloyd back to their side. The Ninjas escape with the teachers, but are confronted by Garmadon's evil creations, who have been wreaking havoc and assaulted Sensei Wu (the Dark Jay even kissing Nya). Lloyd convinces the boys to be good, and they make Ninja suits and attack the evil Ninjas. After destroying Garmadon's creation, the teachers decide to celebrate. The Ninjas drive back to Ninjago city in the Ultra Sonic Raider, and receive a message from Lord Garmadon saying that he will be back.

Ninjaball Run

When the Ninja learn that Dareth's Mojo Dojo is to be destroyed and Dareth doesn't have the money to save it, our heroes enter the annual NinjaBall Run, a massive road-race across Ninjago, to win its cash prize in order to save the dojo. The Ninja in the Ultra Sonic Raider and on the Ultra Dragon, their opposition include: the Serpentine Bus, who have just broken Skales out of jail, police, The Black Bounty, Kruncha and Nuckal, the royal blacksmiths, Ed and Edna, The boarding school for bad boys,Turbo boosted Mailman bike and the pirate van. The pirates, mailman, and royal blacksmiths crash and are eliminated. The Ninja run out of fuel, but Ed and Edna come and help, they transfer fuel to the Ultra Sonic Raider. The Serpentine jump from the Dark Bounty to the Ultra Sonic Raider in attempt to stop the Ninja. Ed and Edna crash, and Jay takes a part to assure their car crosses the finish line. The Ninja speed on, and are winning, but in the final stretch, Lord Garmadon uses his Mega Weapon to create a giant crevasse in the ground. Kai uses a secret weapon installed by Nya and transfers the Ultra Sonic Raider into its flying form. The race is a photo finish, and the Ninja win thanks to the part Jay took from his parent's car. Garmadon is enraged, since 'his ship is bigger'. But Lloyd takes back the Bounty, and the cops try to arrest the Dark Lord. The Serpentine bus drives in and picks up Garmadon, and Darreth, together with the other Ninja, celebrate the salvation of the Dojo.

Note: Final appearance of Kruncha and Nuckal, together with the Skeletons.

Child's Play

The episode begins with Lloyd lamenting that he must train and not play with others or enjoy his youth. Nya then tells the Ninja that Lord Garmadon has been spotted at the city museum. Once there, Lord Garmadon tells his Serpentine followers that he is going to awaken the long dead Grundle, an ancient dinosaur-like creature, and make it hunt the Ninja. In the middle of this process, the Ninja interrupt. They jump on the fossil, but nothing seems to happen at all. Garmadon leaves in a fury, while the Serpentine Generals try to steal a golden sarcophagus for compensation, though they soon leave it behind. The Ninja go after them, but fall behind, and then realize they have been turned into kids by the Mega-weapon's blast. Accused of the thefts, the Ninja try to perform Spinjitzu, but fail dismally, and then the museum director asks them why the Grundle fossil is gone too. The Ninja realize it must have been reawakened and walked off. To escape, the Ninja disguise themselves and run away with some school kids, while the Grundle reappears and scares everyone from the museum. The Ninja call Lloyd and they meet at the arcade, where Lloyd is shocked at what happened to them. He brings them to a comic writer he knows, Rufus "Mother Doomsday" McCallister, to ask him for advice. The writer tells him that a couple of illuma-swords would work well, as the Grundle is nocturnal, but they must win them in a comic knowledge competition. They call Sensei and Nya and tell them what happened. Sensei and Nya then go to the tea lady Miss Take for Tomorrow Tea to turn the Ninja back into their older selves and the Grundle back into bones. Meanwhile, the Grundle shows up at the comic shop, but using the illuma-swords and Lloyd´s powers they manage to hold the Grundle at bay until Sensei and Nya turn up. Lloyd uses the tea to undo the spell of the Mega-Weapon on the Grundle and the Ninja, but it also makes Lloyd become an older version of himself. The episode ends with Rufus handing Lloyd a comic, saying he has earned it. Lloyd declines, saying he already knows how it ends. It is a comic where Lloyd faces off against his father under the stylized title of "Green Ninja".

Wrong Place, Wrong Time

While training Lloyd, the Ninja find out that the Serpentine have returned to the Lost City of Ouroboros and are preparing their vehicles for an all-out assault. The Ninja, together with Lloyd (who has now begun to harness his immense potential), attack and begin to defeat the Serpentine, with Lloyd freezing Garmadon's Mega-weapon. Retreating, Garmadon comes up with a master plan; he will travel back in time and make sure the Ninja are never brought together, changing history in his favor. As he escapes through the time-portal he wishes into existence, the Ninja follow him. They arrive on the very day Nya was kidnapped and Kai was recruited by Sensei Wu. As he leaves the 4-Weapons shop, the Ninja take Wu aside and tell him what is at stake, so that when the Skeletons arrive, history apparently starts repeating itself. But Garmadon, disguised as a Skeleton, makes sure Nya's kidnapping fails and the Ninja are forced to take matters into their own hands to make sure history runs its course, going as far as kidnapping Nya and handing her over to the Skeletons. But Garmadon joins forces with his past self and goes to the Fire Temple, resting place of the Sword of Fire, and prepares to defeat Kai. The Ninja from the present arrive and fight back, before realizing that the only way to heal the damage done is to destroy the Mega-weapon. Using the Golden Weapons, which Jay has seemingly stolen from their past selves, the Ninja, with the help of Sensei Wu, destroy the Mega-weapon, and everything changes back to the way it was, removing the Mega-weapon from the timeline. When everything resets, no-one but the Ninja seem to remember the Mega-weapon existed, seemingly confirming that their quest has become far easier.

Note: Final appearance of Mega-Weapon, the Golden Weapons, and Samukai.

The Stone Army

As the Serpentine battle in the City of Ouroboros, Garmadon arrives with his master plan; he has remembered the 'Island of Darkness' mentioned in Captain Soto's logs and plans to find it, and use its power for himself. While they are at sea, the Serpentine Generals betray him, throwing him from their Rattlecopter into the sea, and Skales is declared their leader. Meanwhile, the Ninja are called to the Museum of History to confront a strange force; venom from the Great Devourer has leaked into the sewers and brought a mass of tiny stone warriors to life. The Ninja easily defeat them, then meet up with Sensei Wu and Misako, who is revealed to be Lloyd's mother. Lloyd, bitter about Misako apparently abandoning him, finds out that his mother has been trying to find a way of restoring the balance without endangering either Lloyd or Garmadon. To this end, she reveals the full story of Ninjago; in the beginning, there was the First Spinjitzu Master, but against him was pitted a being called the Overlord, the first and greatest dark power. The Overlord created the Stone Warriors to aid him in battle, and, to prevent good losing the battle, the First Spinjitzu Master split the land he had created in two, with the Overlord trapped on the dark half of Ninjago, which vanished. Even as Misako is explaining, the venom of the Devourer brings a huge, four-armed stone warrior to life. It immediately goes on the rampage and pursues the Ninja through the museum. Thankfully, they coordinate and trick the Stone Warrior into toppling down the bottomless pit where he was found. After this, Misako joines the group. Meanwhile, Garmadon washes up on an unknown tropical island and is guided by an unseen force to a stone monument atop the island, with four levers perfectly suited for him. He turns them, and the other half of Ninjago, corrupted by the Overlord's shadow, rises around him.

Note: First appearance of Misako, the Stone Army, and the Overlord.
