Former soldier Shingo Hojo, French spy Remy Shimada, and Bronx gangster Killy Gagley aren't exactly your "hero of justice" types. They'd rather be flirting, bantering, and goofing off than battling evil. But when the malicious worldwide organization Docooga attempts to steal a new, powerful form of energy called Beamler, they'll take up arms to fight them - in the giant robot, GoShogun. Now pursued around the world in their teleporting carrier Good Thunder, GoShogun's piloting team must keep Docooga at bay while foiling their eccentric enforcers, righting wrongs they come across, and occasionally facing ghosts from their own tragic pasts. It's an unexpected combination of drama, satire, and giant robot action.

In the early 21st century, the villainous organization Dokuga has achieved world domination through political, economic, and military control. The organization attempts to draft the brilliant physicist Professor Sanada into its service, but he commits suicide rather than allowing his research to fall into their hands. The organization attempts to replace Sanada with his son Kenta, but he is rescued by the teleporting fortress Good Thunder. The crew uses the mysterious energy form Beamler to operate teleportation devices and the giant battle robot, GoShogun. The energy derives from a meteorite fragment found on the site of the Tunguska event. The crew travels the world, trying to undermine Dokuga's control through various missions.—Dimos I
