Heavy Iron
Heavy Iron is a Cardbot best known as a major antagonist in Metal Cardbot. He's a dangerous outlaw with a reputation across the universe for his overwhelming strength and destructive capabilities—basically the kind of threat that can take down pretty much any other Metal Cardbot without breaking a sweat.
His main scheme involved conquering Earth and transforming it into his home planet, Machina, using the Star Crown he'd stolen from Black Hook. That plan fell apart when he was finally defeated, which led to him entrusting the future of the Cardbots to Jun Grant.
In Metal Cardbot W (the third season), Heavy Iron gets hit with the Beast Virus and undergoes a major reformatting. He emerges as Heavy Iron W (헤비아이언W), now functioning as a Wild Cardbot carrier—a pretty significant shift from his previous form.
