Since Luffy has a tanned complexion and Robin is fair - skinned, the baby could have a unique skin tone that's a blend of the two. The baby's build could be small and cute at first but with the potential to grow strong like Luffy. It might also have Robin's long fingers, which could be a sign of future dexterity.
The baby might have Percy's dark hair, as that's a distinct feature of his. And perhaps it would have Hera's piercing eyes, which are often described as having a certain regal quality. It could also have a sort of glow about it, a combination of Percy's heroic aura and Hera's divine presence.
Well, it could be that the baby has a mix of Mal and Ben's features. Its skin tone might be a blend of Mal's slightly tanned complexion and Ben's fair skin. The baby's hair could be a lighter shade of purple, like a pastel purple, and it could have Ben's strong jawline. Also, the baby might have a small, cute nose that is a bit like Mal's.
The baby might have Ivy's green - tinted skin, a sign of her connection to plants. And perhaps Harley's bright blue eyes and a wild, unruly shock of hair like Harley's pigtails.
First of all, the relationship between Luffy and Robin would need to be explored more deeply in this fanfiction. Their connection would be the foundation for the story of having a baby. As Robin's pregnancy progresses, the crew would face difficulties like finding proper medical help. And the child's birth could be a turning point in the story, maybe attracting the attention of powerful enemies or allies. It could also bring out new sides of the characters, like Nami becoming more motherly towards Robin.
Their friends would probably be very excited. They might bring gifts for the baby, like special toys or clothes. For example, Starfire could bring some alien - made baby clothes that have unique properties. Cyborg might build a high - tech baby crib with all sorts of safety features and fun gadgets for the baby to play with.
Their relationship would become more complex. They would now have the added bond of being parents. They would need to rely on each other more, not just as partners in fighting crime but also in raising a child. For instance, they would have to make joint decisions about the baby's upbringing, like what school to send it to in the future.
Cyborg could be very protective. He might upgrade the security systems around the Titans' tower to ensure the baby's safety. And he could also build some cool baby - friendly gadgets, like a high - tech crib or a baby monitor with advanced features. Aqualad, if he were to visit, would bring unique gifts from the underwater world, and he'd be fascinated by how this new life in the Titans' family is growing up with such diverse parents.
They would become more united as they have a common responsibility. Zoro would be more in tune with Robin's feelings, and Robin would rely on Zoro more for protection.
Their relationship would likely become more deeply connected. Having a baby together means they share a new level of responsibility. They would need to rely on each other more, and their bond would strengthen as they face the challenges of parenting.
It's possible that the baby's parents are from a rival pirate crew. In the 'luffy finds a baby fanfiction', this could lead to a lot of drama as Luffy has to decide whether to return the baby to its potentially dangerous family or keep it safe with his own crew. Or perhaps the baby's parents were victims of a powerful and evil force, and Luffy feels compelled to protect the baby from the same fate.
