- Not to be confused with the actual set.
The Titan Mech is a Ninja Vehicle built by P.I.X.A.L. along with Jay and Kai to fight off the Pyro Vipers till it was banished to the Never-Realm. After it was banished, Lloyd and "Red" finds the mech inside a cave and later uses it to find Zane.
Shortly after the end of the Oni Invasion, P.I.X.A.L. had been working on the Samurai X Cave 2.0 for six months. While working on the base, she began building the Titan Mech; however, she wasn't able to complete it and stored it for later.
With the Ninja, Wu, and P.I.X.A.L. trapped in the Underground Base, P.I.X.A.L. brings her backup plan which is an unfinished Titan Mech. Kai, Jay, and P.I.X.A.L. then begin working on it to prepare for the worst.
Inside the Monastery of Spinjitzu, the Pyro Vipers were trying to break through the doors of the Samurai X Cave 2.0 by slamming Elemental Cobras into the door. Inside the base, Kai, Jay, and P.I.X.A.L. were working on the Titan Mech in order to fight Aspheera. When Jay turned on the mech, it was working at first before shutting down.
The Pyro Vipers destroy the door to the Underground Base, but they cannot find Wu until Jay gives away their hiding spot by sneezing. When Aspheera thought she could finally have revenge against Wu, the Titan Mech activates and defends the Ninja and Wu. Despite this, Aspheera is able to overpower the mech by using rocks to bring down the mech. She then attempts to destroy the mech using her staff, but P.I.X.A.L. blocks the shot with the arm of the mech causing that part to disappear.
During the epic Forbidden Spinjitzu battle, Aspheera attempts to destroy Wu by using her staff, but he dodges and instead hits the Titan Mech, causing it to disappear.
In the Never-Realm, the Titan Mech is seen in the snow with footprints leading away from it.
Nya detects the signal of the tracker and the Ninja travel to it but are ambushes by wolves and travel to the Great Lake instead.
Nya examines the tracker and notices that the signal is faint, which makes no sense due to the age of the battery.
Lloyd and "Red" walked through a long vast area that was probably a desert, and then stumbled into an Eagle's home, with many bones. "Red" eventually found a cave, and the Titan Mech was there, but he found a recording of Zane, remarking that he may be dead. He worked on the mech, and then fought the Giant Eagle with it. After the battle, they use it to continue their journey to find Zane.
