Ultraman Wiki

Mighty Jack (マイティジャック, Maiti Jakku) was a tokusatsu science fiction, espionage and action TV series created by Japanese effects wizard Eiji Tsuburaya and produced by Tsuburaya Productions. It was broadcast every week on Saturdays at 20:00 to 20:56 on Fuji TV from April 6 to June 29, 1968, with a total of thirteen 45-minute episodes. The following week, a sequel series titled Fight! Mighty Jack aired.

In 1986, a feature-length film of the same name consisting of footage from episodes 1 and 6 dubbed in English was released in the United States by American producer Sandy Frank. The same was done with footage of Star Wolf to form two films and Army of the Apes to create Time of the Apes, and all four films were shown as Mystery Science Theater 3000 episodes in 1988.


The music for the episodes was done by Isao Tomita. Reportedly, Eiji Tsuburaya considered this series his masterwork because the focus was on the people rather than on the vehicles and special effects (the show never had any monsters or aliens, as his more famous shows Ultra Q, Ultraman and Ultraseven did.) This focus on the people was similar to the works of Gerry Anderson, of which Eiji was a big fan. The Mighty Jack mecha/HQ featured in this series also has some similarities to Eiji's previous TV masterpiece, Ultraseven.

Ratings were low for the series, although Fight! Mighty Jack fared better, perhaps because of its inclusion of monsters and aliens rather than purely human evil-doers like Q. The insignia of the titular heroic spy team also become the current logo for Tsuburaya Productions.[1]


"Mighty Jack" is a top-secret international peacekeeping organisation's 11 agents, established for the purpose of "defense", "construction" and "rescue". They fight the plots of the organisation known as "Q" with the technologically advanced flying Mighty-Gō, armed with an array of weapons. The show incorporated spy and mecha themes.
