If you wanna go real hardcore Goranger. But honestly, Zyuranger should be fine as a starting point. If you would still like to start pre-Zyuranger, I recommend one of the following:



Choshinsei Flashman: In 1966, five Earth children were abducted by aliens only to be saved by the people of the Flash Solar System. They train the children to be warriors who will protect Earth from the evil Mess Empire.

Chojyu Sentai Liveman: Three top ranking students from Academia Island join Volt and serve the evil Dr. Bias. Classmates Yuusuke, Jou, and Megumi, who lost two other friends to the three traitors have been preparing ever since and battle Volt and their former peers to save Earth as Liveman. They later are joined with the younger siblings of their fallen friends to be a five-person team.

Kousoku Sentai Turboranger: As Earth's pollution gets worse, the Bouma Hundred Tribe are awaken from their slumber. A fairy named Seelon picks five high school students to fight the Bouma. With the aid of Dr. Dazai, the five teens become the first all-teenager team, Turboranger.

Chojin Sentai Jetman: A soldier, an heiress, a delinquent, a farmer, and a school girl make up a team of five superheroes bombarded by Birdonic Waves who have the ability to fly and fight the evil Vyrams. The show is quite a homage to Gatchaman(or G-Force) in many ways.
