The Zeroids Action Sets were a line of robot toys from the Planet Zero introduced by the Ideal Toy Company in 1967.
Consisting of Zintar, Zobor and Zerak, the Zeroids powered their way into the imaginations of boys for nearly a decade. The robots were powered by a small electric motor and appeared as the brand name "Motorific" in Ideal Corp racing slot cars, and "Boaterific" powered toy motorboats.
