A supervillain who is after Tony's technology could also be the main antagonist. They might think that by getting rid of Pepper, they can make Tony vulnerable and more likely to hand over his valuable tech secrets.
It could be a new, powerful business rival of Stark Industries. This rival, jealous of Tony's success and his relationship with Pepper, might target her to break Tony. They could use underhanded tactics like corporate espionage that turns deadly.
One possible scenario could be that she sacrifices herself to save Tony Stark. Maybe in a battle against a powerful enemy, she steps in front of a deadly attack meant for him.
Pepper Potts is a character in the Iron Man movies and Marvel Comics. She is Tony Stark's (Iron Man) close confidante and later his love interest. She is known for her intelligence, business acumen, and her role in Stark Industries, helping Tony manage his company and often getting involved in his superhero affairs.
A rival medicine cat from another Clan might be the main antagonist. They could see Alderheart as a threat to their own status or the well - being of their Clan. So they might use dark magic or some underhanded tactics to bring about his death.
A dark and mysterious sorcerer could also be the main antagonist. The sorcerer has a long - standing grudge against Byakuya's family or the place he protects. Using dark magic, the sorcerer sets up a series of deadly traps and curses, which ultimately lead to Byakuya's death.
Well, the fanfic might focus on the relationship between Pepper's daughter and the other Avengers. For example, the daughter could look up to Captain America as a role model and he could help guide her in learning about values like justice and loyalty. This would add an interesting dynamic to the story as the Avengers become part of the girl's life in different ways.
Perhaps Pepper Potts would interact with each Avenger in unique ways. For example, she could have in - depth conversations with Tony Stark about how his superhero activities affect their business. With Captain America, she might discuss the values and ethics of the Avengers' actions. And with Thor, she could be fascinated by the Asgardian culture he represents.
It could be an ancient dark ninja who wants to use Naruto's new 'avatar of death' powers for his own evil purposes. This ninja might have been researching death - related jutsus for years and sees Naruto as the key to his ultimate power.
Trigon could also be the main antagonist. Given his immense power and his connection to Raven, he could target Beast Boy as a way to get to Raven or simply to cause chaos among the Teen Titans. His demonic powers could be too much for Beast Boy to handle, ultimately resulting in Beast Boy's death.
Maybe it's an old enemy of the Avengers who realizes that by taking out Bruce Banner, they can severely weaken the team. They could use mind - control or some other devious means to drive Banner to a point of no return, leading to his death. So this long - standing enemy of the Avengers could be the main antagonist in the fanfic.
I really like the fanfic 'Pepper's Perspective'. This one is interesting because it's told from Pepper's point of view. It gives a deeper understanding of how she feels about Tony, both his genius side and his flaws. It also has some great scenes where she helps him make important decisions regarding Stark Industries.
