Rangers (Omniverse)

A Power Ranger is a human or humanoid warrior who morphs from a natural, unpowered form (often using a device called a Morpher) into a superhuman form clad in a full-body costume (irreverently called spandex on more than one occasion but actually an unknown composition), as well as a helmet with an opaque/one way visor, which in many cases serves to protect his or her identity from the public.
