As Himitsu Sentai Gorenger and J.A.K.Q. Dengekitai were Shotaro Ishinomori's creations, elements from Ishinomori's other series (Kikaider and Kamen Rider) could be mentioned. These other heroes are mentioned when Joker tells the J.A.K.Q. that the world is fighting the resurrected CRIME and the Crime Big Four. Aside from Kikaider, the Gorengers were fighting General Sahara in the Sahara desert in North Africa, Kamen Rider V3 was fighting Baron Iron Mask's Iron Mask Battalion in Europe, and Kamen Rider Amazon was continuing his battle in the Amazon. While the Gorengers would of course team up with J.A.K.Q., Kikaider and the two Kamen Riders do not appear in the flesh.
