The Power Rangers are no more then a live version of the cartoon called VOLTRON from the early 1980's.

Power Rangers is based of a show from Japan called Super Sentai. which predates voltron ( the japenese series dubbed into Voltron is owned by the same company.

Indeed, precisely what PRangerX said.

While Voltron and Power Rangers are similar in concept, Power Rangers actually is adapted from a Sentai series that first started all the way back in 1975 by a Japanese company called Toei.

However Voltron was a joint venture between Toei's Animation department as well as Worlds Events Productions.

Voltron used footage from the 81-82 series caled "Beast King GoLion" as well as the 82-83 series which was called "Armored Fleet Dairugger XV."
