The Arc Station Infection
An epidemic in which people's bodily fluids are turning blue spreads across Tokyo, and the JSDF suspects that the Arc Station is causing it and puts Tony under watch. He is approached by Sakurai who informs him that a satellite has been taken over by a Zodiac warrior, which is causing the radiation. Meanwhile, Nanami also gets sick from the radiation. Using an experimental coating to protect him from the radiation, Iron Man launches into space with the help of Sakurai to face the Zodiac. However, he is at a disadvantage in zero gravity and is taken inside where he is exposed to high radiation. However, Iron Man manages to send the radiation data back to Earth so they can cure the victims, and break free from the Zodiac and destroy it.

Iron Man
Tony Stark, CEO of a large weapons manufacturer, physicist, engineer, and brilliant inventor, is wounded by shrapnel from one of his own weapons. While held captive by terrorists, he develops the Iron Man Suit and escapes. From that day on, he vows not to waste his second chance at life and to change the world for the better. For that purpose, he comes to Japan.
In Lab 23 in Japan, great strides have been taken to develop, and build, a unique power station which does not run on fossil fuels, the Arc Station. Stark intends to join this project, and, for that, he is ready to announce his retirement as Iron Man. At the same time, he will also announce the Mass-produced Iron Men, to which he will pass on his duties. However, during the ceremonies, Stark is suddenly attacked by combat mecha belonging to an organization known as Zodiac.
