A common plotline could be the friends' reactions. The Avengers, for instance, might throw a big baby shower for them. Thor could bring some Asgardian gifts, and Hulk might be a bit clumsy but very sweet around Pepper. There could also be a plot where an enemy tries to use Pepper's pregnancy against Tony, but they outwit the enemy together and this strengthens their relationship as they look forward to the new addition to their family.
In this fanfiction, Pepper might struggle a bit with the idea of being pregnant while Tony is constantly in the spotlight as Iron Man. She could worry about how their child will grow up in such a public environment. However, Tony reassures her that they can create a normal family life within their extraordinary circumstances.
It could be that Tony is under some sort of mind - control or influence that makes him cheat on Pepper. Then the story might focus on Pepper's journey to break the control over Tony and save their relationship.
One common theme is the anticipation of parenthood. Tony might be shown as both excited and nervous about becoming a father. He could be constantly thinking about how to keep Pepper and the baby safe, especially considering his dangerous lifestyle as Iron Man.
At first, Tony might be in denial. He's so used to having Pepper by his side that he can't fathom her leaving, especially when she's pregnant. As time goes on, he could become very sad and start to reflect on what he did wrong in their relationship. He might try to win her back, using his resources and intelligence to show her that he can be a good partner and father.
One common theme is the couple's adjustment to the new situation. They have to deal with the changes in their relationship and their lives. Another theme is the excitement and fear of becoming parents.
One idea could be a story where Tony is overly protective of Pepper during her pregnancy. He starts inventing all kinds of baby - related gadgets, like a super - advanced baby monitor that can also analyze the baby's health in real - time. Maybe he even tries to build a mini - Iron Man suit for the baby before it's born.
Well, another way to find such fanfiction could be through fanfiction.net. However, the quality might vary. In these types of fanfictions, often the story might revolve around how Tony deals with Pepper's pregnancy, like his over - protectiveness or his excitement about becoming a father. It could also show Pepper's perspective, her concerns, and her joys during this period.
There are also plotlines that involve Peter introducing Tony and Pepper to his friends from school. This leads to some really fun and awkward situations as the high - tech world of the Starks collides with the normal teenage world of Peter's friends.
Perhaps Pepper, in an attempt to protect Tony from himself, takes extreme measures. For example, she could sell off Stark Industries' technology that Tony was using for his Iron Man suits without his consent. This would be a huge betrayal in Tony's eyes as his technology and the Iron Man identity are so closely tied to him. It could lead to a rift between them that is difficult to mend as Tony feels violated and Pepper believes she was doing the right thing to keep him safe.
One great Pepper and Tony pregnant fanfiction is 'A New Beginning'. It beautifully depicts their journey into parenthood, with lots of tender moments between them. The story also shows how they balance their superhero duties with the anticipation of a new life.
