Iron Man's origin in the comics involves Tony Stark getting captured and using his engineering skills to create the first Iron Man suit to escape. After that, he continued to improve and develop the technology to become the hero we know.
Iron Man isn't alive. The comic universe is complex and his character's story has taken many turns, but as of now, he's not among the living characters.
In certain comic arcs, Iron Man's fate was sealed and he passed away. But comic universes are complex and sometimes characters can return or have alternate timelines.
There's also the Crimson Dynamo. These are different individuals who take on the mantle of the Crimson Dynamo over time. They are usually Soviet or Russian - affiliated villains who have their own high - tech armored suits. Their battles with Iron Man often involve political undertones as well as just pure superhero - villain combat.
