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

Aldrich Killian's War: Showdown with Killian

While Stark continued to react in horror, Aldrich Killian then appeared and even mocked Stark, claiming that if he was in Stark's position, he would have caught Pepper Potts. Infuriated, Stark then ran forward in order to engage in a final fight with Killian. When Killian leaped into the air to strike Stark, he then dived underneath him and donned the Mark XVI armor.

Even with his armor on, Tony found Killian was the superior fighter and the situation was made even worse by Killian's Extremis abilities, which could penetrate any armor with relative ease, using his red hot fists to cut through the metal armor and attempt to kill Iron Man. As their battle continued, Iron Man did all he could to subdue Killian, but found that he could withstand and heal from any strike and his strength also surpassed Stark's, even tearing off part of the Armor from his left hand and healing from having his left hand broken when they clashed their fists. When he was pinned down, Iron Man again exited his suit to avoid Killian's burning fist.

Having launched himself off the edge of the platform, Iron Man then donned the Mark XL in midair and attacked Killian once again. Iron Man flew Killian across the battle field but was still unable to tire him out, as all his attempts to stop Killian were met with superior fighting skills and his armor was once again cut to pieces by all of Killian's Extremis powers, with Killian almost cutting off Iron Man's leg at one point before he was finally able to gain the upper hand.

Iron Man was able to avoid death once again by ejecting out of his suit seconds before Killian ripped it apart with his bare hands, falling hard on his back onto the platform below. Standing alone on the platform, Stark, now armor-less due to the rest of the Iron Legion being preoccupied with Stark's command to destroy all of Killian's Extremis Soldiers, awaited the arrival of the Mark XLII but was soon deflated when it crashed and disassembled once again.

Amused at Stark's failed attempt to don another armor to continuing fighting against him, Killian mockingly spoke to Stark about him not deserving Pepper Potts and claiming that he was close to making her perfect in his eyes by injecting her with Extremis. Stark told Killian that he was right that he did not deserve her but that she already was perfect and sent the Mark XLII onto Killian, trapping him with all the thrusters put on full power, pinning Killian against the wall.

As Killian yelled out in anger at seemingly being defeated, Stark then ordered J.A.R.V.I.S. to let the armor self-destruct while he escaped. Diving down off the platform, Stark avoided the massive explosion behind him, which seemingly destroyed Killian once and for all. As the fireball continued to grow and destroyed most of the Norco, Stark summoned the Mark XV to catch him as the leaped for safety, only for the armor to fail on the way down by crashing into the platform, causing Stark to crash land, barely avoiding all of the flames and the debris that followed him down from the explosion.
