Iron Man Armor: Mark XXI

The Mark XXI armor (also known as the Midas Armor) is one of Tony's armors that can go at supersonic speeds. Its speeds are only beaten by the Mark XL. It is part of the Iron Legion.

Abilities
Like the Mark XIX, the Mark XXI can fly at supersonic speeds. It has the potential to make a sonic boom, but might fall apart. This is why Tony made the Mark XL, which can go at hypervelocity speeds without falling apart.
