|“Who's trying to get away?! There are more of us than you! And we're not afraid to use our weapons.”|
|— The Mechanic to the Ninja about him and his henchmen in "Would You Like to Enter Prime Empire?"|
The Mechanic's Henchmen are a gang of thugs who work for the Mechanic.
The Mechanic's Henchmen are seen admiring the new upgrades on the Noodle Truck. The Mechanic agrees and attempts to show them a noodle dispenser; however, his robot arm can't press the button. One of the henchmen presses it for him, and The Mechanic gets upset by splashing the noodles on him.
The Mechanic and his henchmen invade an unknown warehouse to find the Prime Empire Motherboard. They discover it, but the Ninja catch them in the act. The Mechanic's Henchmen then fight for possession of the motherboard before The Mechanic is able to grab it and escape.
Meanwhile, the other henchmen are building the Manifestation Gate to bring Unagami from Prime Empire. When they completed the gate, they hook up Zane to the gate as a power source and The Mechanic turns on the gate. Later, P.I.X.A.L. arrives and fights some of the henchmen. As the gateway becomes stronger, some of the henchmen flee from the glowing light.
The Mechanic's Henchmen are seen ironically running away from the Manifestation Gate. Some time later, two henchmen are driving a truck before the Empire Dragon approaches them. Luckily, Jay distracts the dragon and fights it.
