The story of Metal Cardbot begins when the planet Machina is suddenly destroyed, forcing its inhabitants—mechanical lifeforms—to flee to Earth. They remain in hiding for millennia, disguised as ordinary vehicles, awaiting the right moment to re-emerge. In the present day, a boy named Jun discovers a special device called the Metal Breath. This device connects him to Blue Cop, a police car-shaped Metal Cardbot who becomes his first partner.

Jun and Blue Cop travel across the city searching for the scattered Metal Cardbots, sealing them into cards so they can coexist safely with humans. However, not all Metal Cardbots readily accept the presence of humans; some are suspicious or angry, while others cause destruction because they feel threatened. Along the way, they must contend with a figure who seeks to claim that power for themselves. At its heart, the story is about genuine friendship, trust built over time, and unwavering loyalty.
