The police took chase to a mysterious man in black, who was an Invader in disguise, who was trying to get the Invaders ship. But when the police had the man in black cornered the Invaders shot down a ray that covered only the man in black and turn him into the monster Iron. Iron showed his strange alien powers, and easily began destroying the town he was in, however Kyotaro Kagami, who had just received the mirror-pendant from the 2nd dimension transformed into Mirrorman for the first time and after a short battle, he quickly finished off Iron by using his Mirror Shot attack on Iron's chest killing him instantly, Iron then began to bleed a sickly green blood and then went up in virdescent flames.
- Iron's cry is altered Gomora roar.
- Iron would later inspire the mirror demon Shiyu, and the alien general Iaron.
