Go, Go, Samantha Power Rangers: Enforce Samantha Power's will!
Rather than fighting giant monsters like the Mighty Morphin Power Rangers, the Mighty Samantha Power Rangers will go fight despots and warlords and prevent genocides.
They should still have to wear the same silly outfits, though. When dictators and war criminals see them, they'll fall down laughing, and then it will be easier to defeat them!
