Iron Man Armor: Mark XXXI

The Iron Man Armor: Mark XXXI, codenamed Piston, was Tony Stark's thirty-first Iron Man suit and was a mix of the Mark XXI and the Mark XXX, making it both fast and power efficient. It was a part of the Iron Legion and was destroyed during the Clean Slate Protocol.
==History==
The Piston Armor was summoned along with the rest of the Iron Legion to help Tony Stark and James Rhodes during their fight against Aldrich Killian and his Extremis Soldiers. The Piston was among one of the first Armor Suits to fight against the Extremis soldiers and after knocking one out of the four enemies, the Mark XXXI was destroyed when surrounded and pounded by three remaining ones, while Piston managed to kill the last one by ramming him to the ground creating a devastating explosion that rendered a platform on the docks unstable, which needed to be supported by the Mark XXXVIII armor.
==Capabilities==
The Mark XXXI can fly at supersonic speeds and not have to recharge for long periods of time.
