J.A.K.Q. Dengekitai (ジャッカー電撃隊 Jakkā Dengekitai, translated into English as J.A.K.Q. 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 5 members, the JAKQ team started out with only 4. 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.
