Tony Stark was a distinguished CEO, physicist, engineer, and inventor who suffered an injury caused by an explosive fragment from his own weapon. He was taken hostage by a group of terrorists where he created the Iron Man Suit and escaped. From then on, he vowed to use his second chance at life to make the world a better place, which led him to Japan. In Japan's Lab 23, the Arc Station, a revolutionary power station that eliminates the use of fossil fuels had been created. Stark decided to join the project and retire as Iron Man. Instead, he will hand over his responsibilities to the Mass-produced Iron Men. However, at the ceremony, Zodiac's combat mecha launched a sudden attack on Stark.
