Mighty Jack
"Mighty Jack" is the name of both a top-secret international peacekeeping organization's 11 agents, and the technologically advanced flying submarine "Mighty-Gō" they use to fight the plots of the terrorist organization "Q".

Fight! Mighty Jack
The more comical sequel series, Fight! Mighty Jack (戦え!マイティジャック, Tatakae! Maiti Jakku), aired on the same network from July 6 to December 28, 1968, with a total of 26 half-hour episodes, equaling the original in length. This series has several humorous references to the early Ultra Series. The opening scene of the series (with a reverse paint-swirling effect forming "MJ" before a burst of red envelops the scene, with a yellow "Fight! Mighty Jack" superimposed) is almost exactly like that of Ultraman. One episode of this series is quite notable, as it features a comical guest appearance by Kohji Moritsugu, who played Dan Moroboshi, the alter-ego of Ultra Seven, poking fun at his popular role. He plays a mechanic, who, in one scene, looked as though he was about to transform into Ultra Seven by pulling the Ultra Eye from his pocket to put it on, but the red object he slowly pulls from his pocket is actually a small wrench, with which he gets right to work on fixing a machine.
