Chōjin Sentai Jetman

Chōjin Sentai Jetman is a Japanese television series. It is the 15th series in Toei's Super Sentai series.
Plot.
This series takes place in 199X. On the Earth Ship, the command center of a defence agency called Sky Force, the guardians of peace on Earth, scientists have developed "Birdonic Waves", a newly developed technology that gives the subject superhuman abilities. Experiments called "J-Protect" were successful. Aya Odagiri, the director of the project, chooses five elite Sky Force officials from Earth to use this technology. Ryuu Tendou, one of the Sky Force officers, is successfully exposed to the Birdonic Waves, making him the first Jetman, the Red Hawk.
However, the Earth Ship is suddenly attacked by Vyram, an evil outer-dimensional organization bent on inter-dimensional domination. They successfully destroy the ship, apparently killing Ryuu's lover and fellow candidate member Rie. In the chaos, the remaining Birdonic Waves for the other four officials become scattered on Earth, hitting four civilians. Odagiri and Tendou successfully escape and begin searching on Earth for the four remaining Jetmen, training them to aid them in stopping Vyram's plans of conquering their dimension.
The series later follows the tribulations of Ryuu as he learns of Rie's survival and enlistment in the Vyram forces, as well as a love triangle between Gai, Ryuu, and Kaori.
Reception.
Jetman was originally going to be adapted into the first season of "Mighty Morphin Power Rangers", but Saban chose its successor, "Kyōryū Sentai Zyuranger" to be the first instead.
