Space Sheriff Gavan

Special Investigation Robo Janperson was the 1993 installment in Toei Company’s Metal Hero Series. The series revolved around Janperson, a robotic detective who patrolled the streets of Tokyo and fought against three different underworld organizations who used super technology to subjugate the masses. Unlike most Metal Heroes, a monster-of-the-week was rarely shown and most of the villains are criminals akin to television police dramas. The name given to this series by Toei for international distribution is Jumperson.

Akebono City is a peaceful community overflowing with humanity. Since there was a Power Spot that released the magical power in the community, the people were distressed by the threat of the demon army Jamanga who are gathering Minus Energy from the frightened masses for a sinister purpose. The secret organization S.H.O.T. was formed to protect the people of the community from the Jamanga, concealing their existence as ordinary members of the Akebono Police Station, which considers demons beyond their jurisdiction. Kenji Narukami, a student of the Narukami Dragon God Style for fighting demons, arrives at Akebono to fight the demons, eventually getting his wish when he is transformed to RyuKenDo and faces off against Jamanga's forces together with his friends to restore peace in the community.

Yusuke, Jo, Megumi, Kenji, Gou and Rui are students at Academia but the latter three decide to turn bad and join forces with the evil army Volt. When the defectors return, their three friends are forced to combat them as Choujuu Sentai Liveman. With the help of an android ally named Colon and a few others along the way, the Liveman must save the world and their friends.

A group of young pirates from space come to Earth to obtain the "Greatest Treasure in the Universe", which can only be acquired after obtaining the Ultimate Powers of the 34 Super Sentai. However, they end up running afoul of the Space Empire Zangyack, whose earlier invasion forces were wiped out by the 34 Super Sentai long ago. As a result, the space pirates use "pirate copies" of the powers of the older teams and fight the Zangyack forces as the Gokaigers.
