Well, it could be a story about how they adjust to being new parents. Maybe Megamind is worried about passing on his 'villain' traits, but Roxanne is there to reassure him. They could face challenges like protecting their baby from Megamind's old enemies who might see the child as a way to get back at him.
The fanfiction might focus on the baby having unique powers. Since Megamind is super - intelligent and Roxanne is strong - willed, their baby could inherit a combination of amazing abilities. It could show the family dynamic as they try to figure out how to help the baby control and use these powers for good.
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.
One possible plot could be that they initially struggle with the idea of becoming parents. Megamind, being from a different world and having his own insecurities, might worry about being a good father. Roxanne could be the one to calm his fears. They could face challenges like protecting their baby from Megamind's old enemies who might see the child as a new target. And as the baby grows, it could inherit some of Megamind's unique powers, leading to a whole new set of adventures for the family.
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.
A possible plot could be that Roxanne's pregnancy is a complete accident. Megamind is initially stunned but then quickly becomes excited. They start preparing for the baby, with Megamind using his intelligence to design the most amazing nursery. However, there are some who oppose their relationship and the idea of them having a child, which creates conflict in the story.
One possible plot could be that Megamind kidnaps Roxanne as part of a plan to prove his intelligence to the city. He might think that by outsmarting the authorities in a 'kidnapping' scenario, he can show that he's not just a villain. However, during the time he has Roxanne captive, he starts to have second thoughts and realizes he doesn't actually want to harm her. This could lead to a change in his character as he tries to figure out how to let her go without looking weak.
One possible plot could be that Megamind, despite his change of heart later in the story, initially kidnaps Roxanne out of desperation. Maybe he thinks that by having her as a hostage, he can prove to Metro Man or the city that he is still a formidable villain. However, during the time he has her captive, he realizes that she is not just a means to an end but a person with her own thoughts and feelings. This could lead to a change in his actions and ultimately a different kind of relationship between them.
In a fanfiction about Megamind and Roxanne's pregnancy, it could be a story full of surprises. Maybe it starts with Roxanne discovering she's pregnant and the initial shock and joy. Megamind, being the unique character he is, might be both excited and a bit terrified about becoming a father. They could face challenges like how to raise a child in a world that has seen so much chaos from Megamind's past actions. The story might also explore how their relationship evolves during this time, from being a couple to soon - to - be parents.
One idea could be to explore how Megamind reacts to the news. He might be initially shocked but then quickly turn into a very protective figure. For example, he could start using his super - intelligence to create the safest environment for Roxanne and their future child.
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.
Some fanfiction ideas might involve Megamind and Roxanne time - traveling. They could go back to important moments in Megamind's past and change things for the better. Another idea is that Roxanne starts a news series specifically about Megamind's good deeds to improve his public image even more. And a more romantic idea could be that Megamind writes a series of love letters to Roxanne, but they get lost and cause all kinds of misunderstandings before finally reaching her.
