Power Rangers released toys of the Megazords- the Ranger's gigantic battle vehicles in various toylines over the years. These Megazords are largely redecos or re-releases of the Deluxe Mecha released by Bandai Japan annually for Super Sentai. Deluxe Megazords were released for every series up until Operation Overdrive (Toyline) wherein Bandai America began releasing the more cost-effective Transforming Megazords. The Deluxe Zords were initially referred to as Power Zord Battle System or Power Zord System, until the third series of Mighty Morphin (Toyline) wherein the term "Deluxe" was used.
