Power Rangers is a long-running American children's television series adapted from the Japanese Super Sentai series. A Power Ranger is a fictional individual who morphs from an unpowered form into a powerful superhero, usually wearing a brightly colored battle suit made of spandex and featuring a helmet with an opaque visor. In many cases, the helmet serves to protect his or her secret identity. A morphed Ranger generally possesses superhuman strength, durability, and hand-to-hand combat ability. Un-morphed Rangers may possess other innate abilities, such as telekinesis, super speed, or invisibility that are usually not directly related to his or her Ranger powers.
