Power Rangers is a long-running American chilren's television series adapted from the Japanese tokusatsu Super Sentai Series, though it is not simply an English dub of the original. Rather, it is 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 are altered to fit a Western audience. However, many of the action sequences featuring the characters in costume and the mecha (referred to as "Zords" in the English series) are typically dubbed.
