Following on from Himitsu Sentai Gorenger came J.A.K.Q. Dengekitai. Airing from April 9, 1977 to December 24, 1977, and once again created by Shotaro Ishinomori, J.A.K.Q. Dengekitaiit ran for 35 episodes.

Once again an evil criminal syndicate, this time known as “CRIME,” are ready to take over the world. Leading them is the evil Iron Claw, who is backed by a network of wealthy and influential sympathizers and employing an army of faceless, leather-masked thugs and cyborg assassins, CRIME seeks to become the most powerful mafia organization in the world.

To combat CRIME, ISSIS, the International Science Special-Investigation Squad, is formed. ISSIS organizes its forces around the world to battle Crime, including Tokyo, Japan. Tokyo’s ISSIS branch commander, Daisuke Kujirai, proposes a radical experiment to aid his forces in Japan. Taking the codename “Joker”, he recruits four young test subjects to undergo his cyborg enhancement project – multi-talented athlete and Olympic Gold medalist Goro Sakurai, disgraced boxing champion Ryu Higashi, critically injured policewoman Karen Mizuki and clinically dead and cryogenically sustained Oceanographer Bunta Daichi. Surgically altered and given various energy manipulation powers and bionic enhancements, the four youths begin their mission to destroy Crime as the crime-busting quartet code-named J.A.K.Q. Dengekitai. Later on, Joker leaves and Sokichi Banba, a master of disguise and a cyborg, becomes their new boss, as Big One.
