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.
CGC Comics is a well-known grading service for comic books. It assesses the condition and authenticity of comics to provide collectors with a standardized grade.
It depends on the specific comic series and issue. Some popular series may have CGC 10 graded copies, but not all. The condition and rarity of the comic play a big role in determining if a CGC 10 exists.
In many cases, CGC comics can be worth it. They add authenticity and can increase the value of rare or significant issues. However, it also depends on your collecting goals and budget.
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.
