The Mark XXXIV Armor (codenamed Southpaw) was Tony Stark's thirty-fourth Iron Man suit and was a prototype suit developed to respond to situations caused by natural disasters. It was part of the Iron Legion. It was destroyed by the Clean Slate Protocol activated by Tony Stark.
The Southpaw Armor was called, 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. During the course of the fight a number of armors were destroyed, though they eventually managed to eliminate all of the Extremis Soldiers. At the end of the battle the remaining suits that were not destroyed by Extremis Soldiers were destroyed when Stark activated the Clean Slate Protocol, including the Mark XXXIV. 
The Mark XXXIV has features that protect the user from getting injured by a tornado, earthquake, or other natural disasters in the field.
