He is reluctant to divulge the secrets of his armored suit, fearing the information will fall into the wrong hands. With Pepper Potts and "Rhodey" Rhodes by his side, Tony must forge new alliances and confront a powerful new enemy.

Legacy returned in Iron Man 2 to build Tony’s new Mk V and Mk VI suits, along with War Machine, Whiplash’s harness, and the Hammer Drones.
