You could write a story about Howard Stark's influence on Iron Man's early years and how it shaped his future.
How about a fanfiction where Howard Stark and Iron Man have to team up across time to solve a major crisis that threatens the world? This could bring out interesting dynamics and show the similarities and differences between them.
Maybe it's a tale where Howard Stark is somehow able to observe Iron Man's adventures from a hidden vantage point, and his reactions shape the story. Or it could be a story set in a parallel universe where Howard Stark has a front-row seat to all of Iron Man's heroic deeds.
Iron Man and Howard Stark would likely start with a bit of shock. Howard might be amazed at the technology Tony has created, and Tony would be in awe of seeing his father alive (if it's that kind of scenario). They'd probably exchange some witty remarks, with Howard being a bit more old - fashioned in his speech. Then they'd start discussing technology, with Howard offering some of his classic insights and Tony showing off his modern advancements.
In many fanfictions, they have heart-to-heart conversations about family and legacy.
There's no official indication in the main Marvel canon that Howard Stark reads Iron Man fanfiction. Howard was a brilliant inventor and businessman, mainly focused on his scientific and entrepreneurial pursuits. Fanfiction is a modern and often fan - created concept that might not have been part of his world view. However, in some alternate universes or fan - speculations, it could be possible, but still not a common or established idea.
He might be confused at first. Howard Stark was from a different era and fanfiction was not a thing during his time. But if he understood the concept, he might be flattered that his son's story had inspired so much creativity among the fans. He could also be critical as he was a perfectionist, and might not like some of the liberties taken in the fan - created stories.
One possible plot could be that Iron Man, Tony Stark, travels back in time and meets his father Howard Stark. He could try to prevent some of the events that led to Howard's death and in the process, learn more about his father's early inventions and ideas. Maybe they collaborate on a new piece of technology that changes the future of the Stark family.
There's also 'Howard's Shadow'. This fanfic focuses on Tony's struggle to live up to his father's reputation. It has a lot of flashbacks to Howard Stark's days, which gives great context to the Iron Man story. It's really interesting to see how Tony navigates the challenges while being in his father's shadow.
Maybe a fanfiction where Tony discovers hidden secrets about Howard's past that change his perspective on their relationship. It could have elements of intrigue and emotional depth.
In many fanfictions, Howard Stark's early tech designs are a major influence. For example, Tony might find an old blueprint of Howard's that gives him an idea for a new Iron Man upgrade.
Well, it could be a story where Howard Stark plays a crucial role in helping the Avengers solve a major crisis. Or perhaps it's a lighthearted encounter where they have a friendly chat and share some insights.
