One possible plotline could be about how Pepper Stark's pregnancy affects her work life. Maybe she has to take time off from her high - powered job, and there are challenges in finding suitable replacements or making sure her projects are still on track.
It could be Tony Stark. Since they have a close relationship in the original storylines, it would be a likely choice. Their relationship has always been full of chemistry, and a pregnancy would add a new dimension to their dynamic.
Their relationship would likely become more intimate and protective. Tony would be constantly worried about Pepper and the baby's safety. He might cut back on his superhero activities to be more present. Pepper, on the other hand, would rely on Tony more for emotional support during her hormonal changes.
Tony Stark and Pepper Potts' wedding was a grand affair. The venue was filled with roses and twinkling lights. All their friends from the Avengers were there. Tony was looking dapper in his suit, and Pepper was a vision in white. As they exchanged their vows, there wasn't a dry eye in the house. Their love story had been through so much, from facing villains to corporate battles, and now they were finally tying the knot. It was a moment of pure joy and celebration for everyone present.
Well, a plot could revolve around Tony's over - protectiveness. He starts inventing all kinds of baby - proofing gadgets for the future. Also, Pepper might struggle with the public attention on her pregnancy, so they decide to take a break and go to a remote location. There, they can focus on their relationship and the upcoming baby. Plus, they could find out that the baby has some extraordinary abilities due to Tony's technology and Pepper's exposure to certain things, which leads to a whole new adventure.
Love and loyalty are common themes. Their relationship is often shown as a deep, abiding love. Another theme is the balance between Tony's high - profile superhero life and Pepper's more grounded business role. Also, the idea of Pepper being Tony's rock, supporting him through his various crises.
There could be a fanfic where an enemy targets all three of them. Bucky, Tony, and Pepper have to team up to fight this common foe. Bucky brings his combat skills, Tony his high - tech gadgets and suits, and Pepper her strategic thinking. It would be a story full of action, with the characters learning to trust and rely on each other in the face of danger.
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.
At first, Tony would be in shock. But then, he'd start trying to jog her memory in his own way. He'd show her all their personal mementos, like the first rose he gave her or the necklace he designed for her. He'd also tell her stories about their adventures together, hoping that something would click. And he'd be very protective of her, not wanting any harm to come to her in her vulnerable state.
In some fanfics, there's a moment where Tony and Bucky finally have an honest conversation about their differences and past grudges. They realize they both have a common goal of protecting the world, and this moment of understanding is really powerful. It's a moment that changes their relationship from hostility to a grudging respect.
