A kid and four cyborg dogs are literally humanity's last defense against an alien invasion nobody believes is coming. The absurdity hits different when you realize the professor had to weaponize his son's pets because actual governments wouldn't listen. This is 1972 mecha stripped down to its purest revenge fantasy: four loyal animals given the power to save the world, led by a boy who's already lost everything to the people who should have protected him.
Professor Hayashi watches his warnings about an impending alien invasion fall on deaf ears. While the world dismisses his claims, salvation arrives from an unexpected source: four dogs his son Tsutomu has befriended. Recognizing their potential, the professor undertakes a radical experiment, transforming the animals into advanced cyborgs equipped with formidable combat capabilities. Now enhanced with technology and guided by young Tsutomu, the canine quartet, Queen, Ace, Jack, and Joker, become humanity's last line of defense against extraterrestrial invaders. Each member brings distinct strengths to their mission as they operate in perfect synchronization. The stakes intensify as the alien threat draws closer to Earth, forcing this unlikely team to test the limits of their new powers. This 1972 film blends retrofuturistic action with genuine stakes, capturing an era when mecha and sci-fi could be straightforward and kinetic. The premise trades in earnest pulp adventure rather than irony or deconstruction. Viewers seeking pure mechanical spectacle and straightforward heroism will find exactly that here.
