Howard Stark is a brilliant industrialist and engineer working with the Strategic Scientific Reserve. A showman inventor as comfortable dazzling a Stark Expo crowd with a hovering car as he is engineering the tools that make the super-soldier program possible. He provides the vita-ray chamber that completes Steve Rogers' transformation and works the controls as the frail recruit is remade into a super soldier. A friend of Peggy Carter and a private defense contractor, he oscillates between the worlds of science, industry, and the war effort.
His genius outfits Captain America for the real fight. He presents Steve with a range of gear. Ultimately, Steve chooses his iconic Vibranium shield. When Steve resolves to go behind enemy lines to save the 107th, its Howard who flies him into Hydra territory and drops him near the enemy base. He later he joins the search of the frozen north that recovers the lost Tesseract from the sea after Steve's tragic crash.
