One of Tony Starks many competitors seek to put an end to the Iron Man's fame. To prove that the Iron Man suite is nothing but a pile of mechanical junk, Drexel Cord will build a bigger and more destructive suite! Enter the Demolisher!

A competitor of Tony Stark's, Drexel Cord, is convinced Stark is more successful because of Iron Man so he builds the Demolisher to destroy the Avenger. Cords daughter however, doesn't agree with her father and goes to warn Iron Man. The Demolisher finds Tony Stark on his private yacht and attacks. Forcing Stark to put on his armor and fight. The Demolisher quickly set his sights on the golden avenger and the fight begins.

Meanwhile Janice Cord has gotten to the Stark Industries plant and meets Jasper Sitwell who takes her with him to get to the Demolisher's master controls. When they get to Drexel Cords lab, a medieval castle, the Demolisher has knocked Iron Man out by keeping him under water and is on his way back to the lab.

Sitwell and Janice break into the lab but Drexel Cord activates the auto-destruct so they won't stop his creation. Luckily Iron Man is still conscious as it seems the auto-destruct destroyed something in the Demolisher robot itself causing it to attack anything in its way, even Cords daughter. Iron Man finally defeats the Demolisher by attacking the Demolisher's insides through an open plate on its back after Drexel Cord distracts the robot, at the cost of his life.
