Chojin sentai Jettoman

A lot of Sentai fans would regard this to be a remake of Gatchaman. Which I do acknowledge the fact they acquire some of the ideas from that anime to create this series. While at the same time it also has the elements you would see in the earlier Super Sentai shows. Including fully masked heroes with unique powers. Costume monsters to fight and giant Mechas to take on giant monsters.

The story takes place in an untold time period in the 90s. Where an air force group is developing a bird energy device that would make any normal human gain powers and be able to transform into a bird man. However a trans-dimensional group called the Vyram has made themselves known to the human race. Threaten them they will destroy all of man kind.

To stop them, five selected young people with bird energy powers form the Jetman team. Together they must learn to set their differences aside and fight the Vyram before they could succeed in world domination.

This is a good series while at time it could get weird like some Sentai shows like the designs of the dimensional beasts. And it also has some morbid and mature moments that would never be released as a Power Rangers series in America despite it being a kids show in Japan.

It's worth watching if you like Super Sentai, but I don't have the heart to say it's the best one.
