J.A.K.Q. Dengekitai

J.A.K.Q. Dengekitai (ジャッカー電撃隊 Jakkā Dengekitai, translated into English as Jacker Blitzkrieg Squad) is the second Sentai series. It aired from April 9 to December 24, 1977. Unlike most of the other Sentai which start out with a team of three or five members, the JAKQ team started out with only four. A fifth member (Big One) appeared in episode 23. J.A.K.Q. Dengekitai was not nearly as popular as Gorenger, only running for 35 episodes. J.A.K.Q. Dengekitai is the second and final Sentai created by Shotaro Ishinomori.

J.A.K.Q. or JAKQ comes from Jack, Ace, King, Queen. The J.A.K.Q. team members are named after playing cards. Their leader goes by the code name of "Joker".

There are no giant monsters or giant robots to fight in J.A.K.Q. Dengekitai. CRIME uses human sized monsters assisted by masked soldiers called Crimers. CRIME also has bat-winged aircraft called Devil Sharks.

JAKQ was the last and one of the only two Sentai series to use only the Sentai name. Afterwards the name "Super Sentai" was used.

Plot
Iron Claw is the "Crime Czar" of a global criminal empire known simply as "Crime". With a network of wealthy and influential sympathizers and employing an army of faceless, leather- masked thugs (Crimers) and cyborg/robot assassins, "Crime" seeks to become the most powerful mafia organization in the world.

To combat this threat, INTERPOL organizes a special taskforce to spearhead the efforts to bring Crime to justice. Based in New York, ISSIS (International Science Special Investigation Squad [Kokusai Kagaku Tokusou Tai]) begins to organize its forces around the world to battle Crime. Tokyo ISSIS branch commander, Kujirai Daisuke, 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 – multitalented athlete and Olympic Gold medalist Goro Sakurai, disgraced Junior Walter Weight Champion boxer 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 "JAKQ – Dengekitai". Later on, uber cyborg and master of disguise Sokichi Banba is added to the team to strengthen their number and step up their attack on Crime.
