Samurai Mech   Mech-enstein    

The Samurai Mech was a large robot used by Nya as Samurai X to protect Ninjago from Serpentine threats. This advanced mech was equipped with a jet pack that allows it to fly, a detachable left fist, a large katana, a net for capturing enemies, and multiple projectile weapons. Later, it was modified to incorporate a seat on its shoulder, allowing a second person to ride the mech.

During the Ghost Warriors' invasion of Ninjago, the Mech was transformed into the Mech-enstein By Ghoultar. Eventually, it was freed from its possession and returned to the Samurai X Cave.

As Nya became the Water Ninja, the Mech lay unused for a while, before it was utilized by P.I.X.A.L., the new Samurai X. It was destroyed by Vermillion and was later remade into a smaller blue mech used by the new Samurai X.

When The Preeminent returned to Ninjago, P.I.X.A.L. used an upgraded third version of the Samurai Mech suit, which is bulkier and far more powerful.

Nya boarded on the Mech, hoping to stop the Serpentine from getting away with the Fangblade. However, she was caught and had her Mech taken away.

All of Nothing

Upon reaching the Constrictai Tomb in the Mountain of a Million Steps, Jay and Nya revealed that they reconfigured the Samurai Mech's left arm and added a seat so Master Wu could join them in the battle. The mech was confiscated and chained up with the Golden Weapons, but used in the ensuing battle after Lloyd freed them.

The Rise of the Great Devourer

Nya tried to take the Fangblades back from Pythor with the Samurai Mech. When he escaped, she and Wu pursued him on her Mech.

Curseworld, Part II

After the Preeminent was destroyed, the mech was presumably freed of possession.

Prior to or during Season 7

P.I.X.A.L. gained control of the mech.

The Attack

P.I.X.A.L. used the mech to save Lloyd when he fell off his dragon. The samurai then landed the mech onto the temple but flew off before Nya could see who she was. However, the mech was shot down by a Vermillion catapult, destroying the mech and assumingly killing P.I.X.A.L., though Nya thought otherwise on the samurai's fate, a suspicion that she was later correct on.

Prior to Dead Man's Squall

P.I.X.A.L. rebuilt the mech and made it look like a short ElectroMech.

Dead Man's Squall

P.I.X.A.L. used it when she was controlled by Harumi. Harumi and Lloyd used it to get off the Bounty. It crashed in the jungle and was not mentioned later.

The Quiet One

Nya managed to find it and give it back to P.I.X.A.L. Later, P.I.X.A.L. uses it to fight the Sons of Garmadon but was defeated.

Dread on Arrival

P.I.X.A.L. used it to get to the Ninjago police department.

Big Trouble, Little Ninjago

P.I.X.A.L. tried to stop the Colossus with the Mech, but was defeated.


P.I.X.A.L. used the Mech to train Lloyd while they hide from the Sons of Garmadon.

The Gilded Path

P.I.X.A.L. tried to stop Garmadon from crushing Nya, Lloyd, and Dareth with the Mech, but Garmadon used his power to blast it out of the sky, and later Killow pulled P.I.X.A.L. from the wreck.

Into the Breach

When the Ninja heard signals coming from NGTV, the others went to save the people there, but P.I.X.A.L. stayed behind in case Lloyd and Garmadon needed her help. She used the mech to fly above the cloud of darkness.

The Fall

When Lloyd finally requested extraction from the corrupted Ninjago City, P.I.X.A.L flew the mech into the cloud of darkness, despite Lloyd expressing concern as to what it could do to her. However, P.I.X.A.L discovered that the mech's fuel had decreased due to waiting up in the sky for so long. P.I.X.A.L managed to use the mech to reach Lloyd and Garmadon and successfully flew it up the side of Borg Tower and out of the cloud, despite the fuel levels being on 1%. While attempting to close the distance between the Bounty and the mech, the mech ran out of fuel and began falling back towards the cloud of darkness. The Bounty appeared just in time to catch them as P.I.X.A.L crash landed the mech onto the deck of the Bounty.

A Rocky Start

The mech was among one of the vehicles P.I.X.A.L. has in the Samurai X Cave 2.0.

The News Never Sleeps

P.I.X.A.L. used the mech to fend off the Elemental Cobras attacking the city.

The Absolute Worst

When P.I.X.A.L.'s radar went off, she used the mech to capture Ultra Violet, The Mechanic, and Fugi-Dove and brought them back to Kryptarium Prison.

The Kaiju Protocol

While the Ninja were in the Never-Realm, P.I.X.A.L. either built another version or upgraded the Samurai mech. She used it to fight the Preeminent, and after the Preeminent snapped an arm off the mech, P.I.X.A.L. had to supercharge it and herself with a powerline. She defeated the Preeminent, then Wu and P.I.X.A.L. sent it back to the Departed Realm.
