Titanium Man Armour
The Titanium Armour was created by Justin Hammer and Hammer Industries using a stolen War Machine Armour as the blueprint.
During the Stark Expo, he attempted to use the suit to fight Tony Stark and James "Rhodey" Rhodes. Following the defeat of Hammer, the iron was taken as evidence by S.H.I.E.L.D
Original Timeline
In the original timeline, Hammer did not create a suit. However the Expo was still attacked, by Ivan Vanko using the Whiplast armour.
