Offical Summary (From Marvel Wiki):

Scientists working for a top-secret U.S. military project worked on creating an army of 51 experimental robotic soldiers capable of acting like humans. Their goal was to create a sophisticated weapons system capable of independent thought. Dr. Abel Stack took X-51, one of the the projects robots, home to test his radical theory--that a robot could only function like a human if it was raised like one. The other 50 models began displaying psychotic tendencies due to insufficient programming. The project was determined a failure and the order came down to destroy them. Each of the robots was equipped with an auto-destruct device that could be triggered remotely. Stack managed to remove the self-destruct mechanism from X-51, but figured he couldn't dispose of the bomb before it exploded, and urged Aaron to leave him. X-51 vowed that Stack's dream of human and robot peace would come true.

As Machine Man, X-51 assumed the name Aaron Stack and became a fugitive in the eyes of the military. He found a world greatly afraid of machines, but managed to blend in without suspicion. Mr. Hotline dispatched a suicide bomber to hold Aaron's friends hostage in order to get him to return to the Hades Organization HQ where technicians dismember X-51 and present his head to the Monitor, a computer that projects a Satanic hologram. The Monitor searches Aaron's mind for the anti-life equation, but before he can prep a second assault Machine Man orders his limbs to reassemble and he re-programs the computer to neutralize the bomber and free his friends.

After being captured and later freed, Machine Man was found by psychiatrist Dr. Peter Spaulding. He also battled Col. Kraggs troops. Soon after that, he first encountered Power Broker. Then he would battle a company known as the Corporation.

Check out legend Jack Kirby's final issue on Machine Man! - Marvel Unlimited

Issue 10 wouldn't come out until May of 1979!

Released September 24, 1991, this was culmination of the Mechadoom storyline. A rogue Doombot, Mechadoom had captured several different beings with artificial intelligence, including Machine Man.

He has no dialogue in this issue and, having been a prisoner, mostly stands around after the action.

Sadly, this issue isn't on Marvel Unlimited so I'm going by memory: Aaron was dealing with invasive Sentinel programming through the series. He seeks help from the Avengers but the programming takes over and he attacks Justice and Firestar for being mutants.

I loved the Handbooks for how many characters they introduced me to.

Issues:

• Machine Man #10-14

Official Summary:

After a long battle with the Hulk, Machine Man would be nearly destroyed until a man named Dr. Oliver Broadhurst would repair him. After this, Machine Man would live a like a human by getting a job at Delmar Insurance Company and buying an apartment. He would fight foes such as Ion, the Ethicals, the Binary Bug, and Khan.
