14Voltron Ripped Off The Power Rangers
Voltron, the other show about universe-saving teenagers with giant robots, was a staple of the mid-1980s. Mighty Morphin Power Rangers, on the other hand, didn't premiere until the fall of 1993. The obvious response is that Power Rangers was a rip-off of Voltron, but, it turns out that's
not right. Kind of.
Both shows are, in fact, conglomerations of existing Japanese television programs. Voltron - the original one, anyway, not the Netflix reboot - is a combination of the Japanese cartoons Beast King GoLion (1981) and Armored Fleet Dairugger XV (1982), cut together with all new plots and redubbed with English dialogue. Because of this, the shows are markedly different from one another.
The Power Rangers franchise, meanwhile, is basically a straight import of the Super Sentai series, a still-popular Japanese franchise that began in 1975 with Himitsu Sentai Goranger. The 16th installment, Kyoryu Sentai Zyuranger, was adapted into the first season of Mighty Morphin Power Rangers. While there was new footage of the Rangers added to set the series stateside, the shows are generally still the same.
So, yes, Voltron beat Power Rangers to America, but Super Sentai came before Beast King GoLion, so maybe we just call it a draw.
