Bio-Man

Bio-Man was a television pilot for an American adaptation of the Super Sentai series, Choudenshi Bioman, produced by Haim Saban in 1986. Although it didn't result in a series, Saban would later successfully adapt Kyoryu Sentai Zyuranger in 1993, starting the Power Rangers franchise.

Though most claim that Bio-Man was a new Americanized dub, there are also claims that Bio-Man was an adaptation, much like Power Rangers.

Story
