A robotic duplicate of Spring Man, created by the ARMS Laboratories. Unlike Spring Man, when Springtron is fully charged, he unleashes a blast of EMP that disables the opponents' extended ARMS within close to his range. He originally was interfering the Grand Prix until he is allowed to participate on version 4.1.0.
He uses the same ARMS as Spring Man's, which are the Toaster, the Boomerang, and the Tribolt. His home stage is the Sparring Ring.
