'Power Rangers' is a long-running American entertainment and merchandising franchise, built around a children's television series featuring teams of costumed heroes. Produced by Saban Entertainment (and later BVS Entertainment under Disney), the Power Rangers concept originated from the Japanese tokusatsu Super Sentai Series. Rather than making an English dub of the original, the American production team put together a "new" production with English-speaking actors spliced in with the original Japanese footage in varying ratios. Due to the very Japanese nature of many of the Super Sentai Series' stories and design, the American shows vary detail to appeal to a Western audience. However, they typically dub many of the action sequences featuring the characters in costume and the mecha (referred to as "Zords" in Power Rangers).
