Metro Man might be more laid - back about it. He'd probably see it as a fun take on their world and might even chuckle at some of the more outlandish interpretations of their battles and relationships. He could also use it as a chance to better understand how the public perceives them both.
Roxanne Ritchi would likely be very observant. She might be looking for how the fanfic writer developed her character, whether it made her seem like just a damsel in distress or if it gave her more agency. She could also be interested in how the fanfic explored her relationship with Megamind and Metro Man in different ways.
The characters might also be intrigued by the creativity of the fanfiction writers. They could see new storylines and character developments that they never considered in their own 'lives' within the movie's plot. It could open their eyes to different possibilities and make them think about their own roles and relationships in new ways. They might even start to wonder if some of these fan - created ideas could have worked in the original movie.
It really depends on the individual character. Those characters who are more open - minded and like to explore new ideas might be more likely to enjoy it. They could see the fanfiction as an extension of their own story. But the more conservative characters would probably be less likely to enjoy it as they prefer the familiar narrative of the original movie.
Roxanne would likely be terrified at first. She's in the hands of a known villain. But being a strong - willed journalist, she would quickly start to look for ways to escape or at least understand Megamind's motives. She might try to talk him out of whatever evil plan he has in mind, using her skills of persuasion.
One possibility is that they might be amused by the creative interpretations of their own personalities in the fanfic. For example, if Metro Man is watching, he could be laughing at how the fanfic writer made him seem even more heroic or perhaps gave him some comical flaws.
Their relationship would likely become more centered around the baby. They would have to work as a team to take care of the little one, which would bring them closer. There would be more communication and cooperation between them.
Roxanne could be initially terrified. After all, being kidnapped is a scary situation. But she's a brave character, so she might quickly start trying to reason with Megamind, asking him why he's doing this and appealing to his better nature.
First, understand the characters. Megamind is a complex character with a villain - turned - hero arc, and Roxanne is a strong - willed journalist. Start with a simple idea, like a day in their lives together. You can then build on it, adding some conflict, like an old enemy returning. Use their unique personalities to drive the story. Megamind's intelligence and Roxanne's determination can create interesting interactions.
Their relationship would likely become more reliant on each other. Megamind would become more protective of Roxanne, constantly worried about her well - being during the pregnancy. Roxanne would rely on Megamind for emotional support as she goes through the physical and hormonal changes. They would also start making joint decisions more often, like choosing names for the baby, or deciding how to decorate the nursery.
Another interesting megamind fanfic idea is to explore Megamind's life before he became a super - villain. Maybe he had a different origin story that we don't know about in the movie. You could write about his early years, his family, and how he got interested in being a villain in the first place.
Love and acceptance are common themes. Since Megamind is often seen as an outsider, the fanfics usually focus on how the reader can see past his villainous exterior and accept him for who he is, leading to a loving relationship.
