The Story of Tony Stark/Iron Man (Marvel Cinematic Universe)

Avengers Civil War: Battle at the HYDRA Facility

Already enraged by the fallout of Steve Rogers' questionable and biased actions over the past few days, Stark snapped and attacked the Winter Soldier to avenge his parents. Donning his helmet back on, Iron Man struck Rogers in the face and shot the gun out of the Soldier's hand before flying him across the facility and pinning him down by forcing his foot against his arm and aiming a blaster shot at his skull.

While they fought, Helmut Zemo made his escape from the facility. Iron Man attempted to shoot the Soldier point blank in the face, but Captain America ran to his aid and threw his shield at his to deflect the attack before he attempted to push Iron Man off the Soldier. Acknowledging their friendship, Iron Man tried to force Rogers out of the fight using the leg clamps which Rogers soon broke free of. Iron Man grabbed the Winter Soldier and flew him into the wall.

The Winter Soldier managed to use his Prosthetic Arm to damage Iron Man's repulsor beam in his hand by crushing it. In response, Iron Man aimed a missile directly at the Winter Soldier's face, which he managed to push out of the way, causing it to destroy much of the entire HYDRA Siberian Facility around them. While the pair became separated, the Winter Soldier regrouped with Captain America while Iron Man was briefly trapped under all of the debris.

As the Winter Soldier made his way towards the exit, Iron Man freed himself and chased after him, only for Captain America to stand in his way. While Captain America insisted that his parents' deaths were not Barnes' fault as HYDRA had control of his mind and it had been ordered by Vasily Karpov, Iron Man ordered him to move. Captain America damaged Iron Man's leg stabilizers before Iron Man used the laser to trap Captain America while he went for Barnes.

While Iron Man quickly caught up with his target, who was attempted to climb up the building to reach the helicopter hatch in the roof, Iron Man kicked him across the facility and took aim at him yet again with a deadly kill shot. However Captain America refused to stand down from the fight, deflecting a lethal repulsor back at Iron Man, disabling the Mark XLVI's targeting system and using a wire to pull him down when Iron Man continued to chase after the Winter Soldier.

When Captain America threw his shield at him, Iron Man was able to shoot it out of the air, leaving Captain America now defenseless and unable to aid Barnes. As he could no longer target Barnes with his missiles, Stark opted to trap Barnes within the bunker for their final showdown. With F.R.I.D.A.Y. informing him that his weapons systems could not target him, Iron Man used his own eye to aim and shoot at Barnes, destroying the main hatch and trapping him inside.

With Barnes now trapped inside, Iron Man charged towards him as they engaged in hand to hand combat until Iron Man began crushing him under the Mark XLVI's weight. Holding him there, Iron Man then questioned if he even remembered killing his mother and father, with the Winter Soldier insisting that he remembered everyone who he had killed for HYDRA. Captain America jumped at the pair, knocking himself and Iron Man back down to the ground floor.
