One possible plot could be about the challenges they face as new parents. Maybe they have to balance their work with taking care of the baby. Gru, with his past of being a villain, might be worried about how his past could affect their child. Lucy, on the other hand, could be using her skills from the Anti - Villain League to keep the family safe. They might also have funny moments like when the Minions try to help with the baby but end up causing chaos.
It could be a story about their journey of discovery as parents. They learn about their baby's likes and dislikes. For example, the baby might love the Minions' antics, which makes the Minions become the baby's best friends. Gru and Lucy also have to deal with the everyday tasks like feeding, changing diapers, and putting the baby to sleep. As they do these things, they grow closer as a couple and become more confident in their parenting abilities.
The plot could revolve around the baby having some unique abilities. Since Gru and Lucy are both in the world of villains and anti - villains, the baby might inherit some special powers or skills. This could lead to them having to protect the baby from other villains who want to use the baby's powers for their own gain. And they would have to teach the baby right from wrong in a world full of moral gray areas.
One plot could be that Gru is overly protective of Lucy during her pregnancy. He tries to baby - proof the whole house in his own wacky way, like using his minions to create special security systems for the baby's room. Meanwhile, Lucy is still trying to keep up with her secret agent duties, which causes some comical misunderstandings between them.
Their relationship would likely become stronger. Having a baby together means they have a new bond that ties them even closer. They would have to rely on each other more, for example, when taking turns to take care of the baby at night.
The plot could involve the challenges they face as new parents. Maybe they struggle with balancing their own relationship while taking care of the baby. There could be financial difficulties or family interference that they have to deal with. And of course, there would be lots of cute moments like the baby's first steps or first words, which would bring them closer as a family.
Well, perhaps the story could start with Lucy finding out she's pregnant. Natsu is initially shocked but then becomes super excited. The pregnancy is filled with little adventures, like Natsu trying to build a perfect nursery using his magic in a rather clumsy way. And when the baby is born, it brings a new sense of hope and family to the whole guild. Everyone pitches in to take care of the baby, and it grows up surrounded by love and magic.
The Vicious 6 could be the antagonists. They might see Gru's preoccupation with Lucy's pregnancy as a weakness and try to take advantage of it. They could plan to kidnap Lucy to get to Gru and force him to give up his new - found family life and return to his old villainous ways.
Maybe it could be about Lucy's journey in raising the baby, like all the challenges she faces, from sleepless nights to learning how to feed the baby properly.
Maybe it could be about a magic spell that accidentally turns Lucy into a baby. Then her friends have to figure out how to reverse the spell while taking care of baby Lucy. They might encounter various challenges and comical situations during this process.
A common theme is their relationship development. Many fanfictions explore how they got closer and fell in love. Another theme is family. Since they are part of a big family with the Minions and the girls, stories often revolve around how they handle family - related situations together.
Well, perhaps in this fanfiction, Natsu calling Lucy 'baby' is a sign of a new level of closeness in their relationship. It could start with Natsu protecting Lucy in a dangerous situation and instinctively calling her 'baby' as he holds her close. This then leads to Lucy being a bit flustered at first but gradually getting used to it and even liking it, and it becomes a special part of their bond.
The plot could be about Lucy taking care of the baby dragon. Maybe she has to hide it from others who might want to harm it. She could be on a quest to find a safe place for the dragon to grow up.
