Luffy would probably be super excited. He's always been on this big adventure, and meeting his dad would be like a new milestone. He might jump up and down and start asking a million questions right away, like what his dad has been doing all this time and if he has any cool stories from his own adventures.
Obviously, Luffy and his dad are the most important characters. Luffy, the main character of the original story, is known for his carefree and determined nature. His dad, on the other hand, is a mysterious and powerful figure.
Well, in 'Luffy meets his dad fanfiction', it could be that Luffy's dad teaches him some new and powerful techniques. Maybe they team up to fight a common enemy. This would be a great opportunity for Luffy to bond with his father on a deeper level.
It depends on the individual gay dad. Some might find it uncomfortable as it highlights a very heteronormative concept that doesn't align with his own identity. Others could use it as an educational opportunity for his children, explaining the differences between different ways of creating families and how all forms of family are valid, regardless of how they are formed.
The reaction would be extremely negative. The 'Harry Potter' universe has a strong sense of family and friendship. Hermione is an important part of Ron's friend group, and Ron's dad is like a parental figure in their world. A fanfiction with this inappropriate plot would not only be against the essence of the story but also against the moral and ethical values that the series promotes. Fans would likely shun any such work.
There could be a story where the daughter has some kind of medical condition that causes lap pain. Her dad, on noticing her discomfort, would be worried sick. He would likely do all he could to ease her pain, from getting her painkillers if appropriate to arranging for proper medical tests to find the root cause of the pain.
I think Shanks would have an interesting reaction. He has known Luffy since he was a kid. Seeing Luffy reach Gear 5, he would probably be proud but also a bit cautious. He might think about how far Luffy has come and also wonder what challenges this new power will bring for Luffy and the world at large.
In some fanfictions, when Luffy meets his dad, there could be an emotional moment. Luffy might be surprised at first. His dad could give him some advice on his journey, like how to better face the powerful enemies in the New World. And maybe he'll share some secrets about Luffy's family history that he didn't know before.
Well, Percy could have had a complex reaction. On one hand, he might have been excited to learn more about his dad in the fanfiction context. This could have led him to explore more about his own identity within that fictional world. He may have started to compare the fanfiction version of his dad to what he thought he knew in reality. Maybe it made him question things he had previously taken for granted. On the other hand, he could also have been a bit overwhelmed by all the new information.
In this fanfiction, perhaps Naruto's hidden jutsu legacy could be revealed. Maybe it shows some secret techniques that he developed but never got to show during the original series.
