I hope this isn't gonna later turn into another Power Rangers VS Super Sentai argument.
But anyway, lets put it this way, Hurricanger is not Ninja Storm in Japanese, but Ninja Storm is not Hurricanger in English either.
Basically, they are both seperate shows. The only thing they have in common is limited to the suits, the mecha/zords and the battle footage that Ninja Storm took from Hurricanger.
Same goes with every other Sentai and PR Series (apart from GoRanger to Jetman).
One thing that HaiTien78 said that was true was that Hurricanger came before Ninja Storm.
Super Sentai has been around since the
1970's, and lasted throughout the
1980's, the
1990's and the
2000's.
The American Power Rangers started in 1993, basically they took battle footage from 1992's ZyuRanger, cut it up and spliced it with American footage (occaisionally they did do their own fight scenes).
So, Power Rangers isn't quite an English version of Super Sentai, just an American TV show "based" on Super Sentai, and Super Sentai was the Japanese show that became the basis of Power Rangers.
This is the OP of the Cantonese version of Hurricanger.

As you can tell by the OP, the characters, etc are completely the same, there's still Yousuke, Nanami, Kouta and co, only difference is it's in Cantonese. And English version would be like the Cantonese, but in English.
