Power Rangers RPM-1
Power Rangers RPM is a post-apocalyptic Power Rangers series in which most of the world has been wiped out by a sentient virus called Venjix. Only one last location remains, the domed city of Corinth, with an artifical sky, holding the last remants of humanity. The rest is a wasteland, populated by Venjix's footsoldiers, Grinders. The Power Rangers, a small group of exosuited people, guard the city under the watchful eye of Colonel Truman, the military officer in charge of the city, and Dr K, the genius scientist. Continuity taken from roughly around 'In and Out' of the Power Rangers RPM season.
