Iron Man Armor Model 31 (Earth-239)

The Magnetic Armor was an attempt by Iron Man to be able to manipulate magnetic fields and resist magnetic attacks.

History
The Model 31 was developed with help from Charles Xavier, right inside the Xavier School with the intention of being able to battle Magneto without being easily defeated. The suit was being created during the completion of the Model 30.

Despite Tony's various backup plans and preparation, the suit was not able to stand up to Magneto's powers and strategy, and Iron Man was defeated by Magneto shortly before the fall of Genosha.

The suit was put away in Tony's private jet for future use or reference. When the Model 30 was rendered unusable during the Mandarin incident, Tony wore this suit again to battle Tem Borjigin in China. The armor was destroyed from the upper torso during their fight.
