Origins
Many fans consider the inspiration for the final version of the Maser Cannon to be the Markalite Cannon from 1957's The Mysterians. The gigantic satelite-like weapon fired a ray/beam from its center, and proved to be very effective. A similer weapon also appeared in 1959's Battle in Outer Space. In 1961, the movie Mothra featured the famous Atomic Heat Ray, a Markalite-like weapon that took the basic design that was featured in the previous films and placed it on wheels. The tank-like form was taken to the next level five years later for the film War of the Gargantuas, the first film to feature an official Maser Cannon.
