Captain Hero was actually a child named Bobby Wright who was abandoned by his teenage mother before he was 6 months old. He then became a ward of the courts.

He became a runaway and it was during one of these times in which he encountered a meteorite which had fallen in to a field that he was crossing. When Bobby tried to pick up the meteorite he was infected with an unknown alien spore that altered his atomic structure.

Captain Hero is born

The young boy had just received super natural powers and as such wanted nothing more than to become a superhero. Bobby had the ability to alter the shape and density of his molecular structure as well as the structure of anything around him. So first he changed his appearance, looking somewhat like Captain Marvel and Captain America in the same body he went on to use his powers similar to superman but unfortunately he did not have the emotional strength for his abilities. Reacting before thinking was his flaw, Eg; he initially goes to P and I and asks to become a hero with them in their Heroes for Hire, but after he is declined the boy in the hero re-emerges and he goes off in a destructive tantrum.

Another major obstacle for the boy was that the alien spore that had given him his power was also killing him. Upon hearing the boys problem P and I took a shinning to the boy even though he had caused immense problems. P and I helped doctors to look after the boy as they searched for a cure.

Death of Iron Fist

The final issue of the Power man and Iron Fist series (no125) sees the death of Iron Fist by the hands of Captain Hero. Iron Fist learns that the boy Bobby Wrights health has taken a turn for the worst and it seems he only has a short time of life left, Iron Fist rushes to the hospital to help the boy and administers healing via his chi. Upon feeling he has helped all that he can Iron Fist sleeps as the ordeal has been very draining, it is at this time that the boy awakes in pain and transformes into Captain Hero and begins to attack the sleeping Iron Fist killing him in the process.

Dark forces at work

Who would of known that the Captain Hero who had killed Iron Fist in the final issue of the series was none other than Super Skrull sent to assassinate Power man and Iron Fist, and that the Iron Fist that had been killed was actually a dooplganger? not me... but that is what had happened as discribed in the pages of Namor.
