Heavy Iron is a cardbot and the main antagonist of Season 1 of the animated series Metal Cardbot.

He is known as a dangerous criminal in the series universe, possessing incredible strength and destructive power, surpassing that of other Cardbots. Heavy Iron's main goal is to take over Earth and terraform it, turning it into a simulacrum of the Machine's home planet. To achieve this, he steals the Star Crown from Black Hook.

The character's nickname "Heavy Iron" stems from his massive, imposing appearance. Visually, his design is somewhat reminiscent of Optimus Prime from the Transformers franchise, and his transformation pattern (the semi-trailer becomes arms and legs, the cabin becomes the head and torso) echoes certain versions of Ultra Magnus (such as the Combiner Wars and Studio Series figures).

Key character traits: prudence, composure, and calm. Heavy Iron prefers to carefully analyze situations rather than act impulsively. His ultimate dream is to possess the Metal Bracelet.

In the Season 1 finale, Heavy Iron is defeated. Afterward, he entrusts the future of the Cardbots to June Grant, marking a definite turn in his journey.
