|“Why did I choose to ride on the back of a jet?!”|
The Mech Jet was a Ninja Vehicle owned by Kai. It was used by Kai to compete in the Speedway Five-Billion. It was built as a jet, however, a Loot-Box acquired during the race turns it into a mech, which Kai uses to take out some of the racers. It is destroyed when Kai and Cole sacrifice themselves to stop the Red Visors.
When the ninja come to Scott for vehicles to use in the Speedway Five-Billion race, he introduces them to the Mech Jet, the Velocity Racers and the Ninja Tuner Car, which are all in need of repair. While Lloyd scopes out the race track, Kai works to fix the jet, just in time for the race to begin.
The vehicles are finished just as the race is set to begin, though the Red Visors locate Scott's Garage and begin to fire upon it. Kai and Cole hop on board the Jet, as Scott manages to hold them off, allowing the ninja to enter the race. They get to the track just as the race starts. The Red Visors infiltrate the race to chase the ninja down. Cole manages to jump onto on of the Whack Rat's Quad Bikes, as Kai drives the jet into a "loot box", which transforms it into a Mech. Kai and Cole both realise that there are too many Red Visors on the track and collectively decide that the team stands a better chance of winning than them. They ram their vehicles into the Red Visor's cars and the Mech is destroyed in an explosion, which takes out the Red Visors and its pilot.
