In fanfiction, if Natsu and Lucy had a baby, it would be a huge shift for their relationship. Natsu would no longer be just the impulsive dragon slayer. He'd have to be a father figure. Lucy, with her kind heart, would pour all her love into the baby. They'd have to work together to balance their guild duties and family life. Natsu might bring the baby on small, safe adventures, teaching the child about the world of magic, while Lucy would make sure the baby has a stable home environment. Their relationship would be centered around this new life they've created.
If it was an accidental and embarrassing incident, they might become more shy around each other at first. But as time passes, they could start to joke about it, which would strengthen their friendship. For example, Natsu might tease Lucy about how she screamed when he accidentally walked in on her in the shower, and Lucy would retaliate with some comment about Natsu's lack of manners.
Natsu and Lucy's relationship would transform in many ways. They would start to see each other in a new light. Natsu would see Lucy as the mother of his child, which would bring out a more nurturing side in him. He might start doing things like bringing her special foods or making sure she gets enough rest. Lucy would see Natsu as the father of her child, and trust him even more with their safety and future. Their relationship would no longer be just about their own adventures and feelings, but also about the future of their family. They would have to make decisions together that are in the best interest of their unborn child, and this would strengthen their bond in a whole new way.
Their relationship can become more nurturing. Natsu, who is usually brash and impulsive, might become more gentle and protective around the baby. Lucy, on the other hand, would be the more practical one, making sure the baby has everything it needs. This would make Natsu see Lucy in a new light, as a motherly figure, and he would respect her even more. Their love for each other could also deepen as they share the joys and challenges of raising a baby.
Their relationship would likely become more intimate and deeper. With a baby on the way, they'd have to rely on each other more. Natsu would probably become more gentle and caring towards Mirajane, and Mirajane would feel more protected by Natsu.
She would fit in very well. The Fairy Tail guild is all about family and acceptance. Given her parents are Lucy and Natsu, she'd be welcomed with open arms. She could learn from the older members like Makarov and Mirajane, and bond with the younger ones like Romeo. Her magic skills would also contribute to the guild's strength during battles or when helping the town.
In a fanfiction, their relationship might develop if they start to open up more about their pasts. Lucy could share more about her family and how she came to be a celestial wizard. Natsu could talk about his search for Igneel. By sharing these deep parts of themselves, they would build a stronger emotional connection. Also, small moments like Natsu saving Lucy from a small danger, like a falling object in the guild hall, can add up and gradually develop their relationship.
In their alone time, they might also discover new things about each other's dreams. If Natsu shares his long - term goal of finding Igneel with Lucy, she could offer her support wholeheartedly. And when Lucy talks about her dreams of becoming a great celestial spirit mage, Natsu would vow to help her achieve it. This sharing of dreams would bring them closer together.
Their wedding would be a grand affair. All the Fairy Tail members would be there. Natsu would be in his best suit, looking a bit uncomfortable but happy. Lucy would be in a beautiful white dress, with her Celestial Spirits perhaps helping with the decorations. There would be lots of food, music, and dancing. Gray might accidentally freeze something during the celebration, and Erza would keep everyone in line. It would be a day filled with laughter and joy.
It could bring them closer. Taking care of a baby together requires a lot of cooperation. They might start to rely on each other more, sharing responsibilities like feeding and protecting the baby. This shared experience could deepen their bond.
He could kidnap her because he believes she's in immediate danger. Natsu is very impulsive and might not have time to explain things properly, so he just takes her away to keep her safe.
