In Gohan vs Naruto fanfics, a really cool plot is when their powers get combined somehow. For example, due to a magical or scientific accident, Gohan's ki and Naruto's chakra merge, creating a new and powerful force. Another interesting plot is when they have to fight in a world that has rules that are different from both of their own. This forces them to adapt in unique ways. Also, a plot where they are both de - powered and have to rely on their wits and basic fighting skills to compete can be very engaging.
In a Gohan vs Naruto fanfic battle, I think Gohan would win. His Saiyan heritage gives him a natural advantage in terms of raw power. He can fly and has energy blasts that could overpower Naruto. Naruto is strong, but his powers are more about ninjutsu and chakra control. Gohan's Super Saiyan forms would be too much for Naruto to handle.
The relationship could develop out of a need for companionship. Gohan, having lost many of his friends and family in battles, is in need of someone who can understand his pain. 18, being an android with her own complex past, also longs for someone to be close to. They meet and initially just offer each other a listening ear. As they talk more, they find that they can comfort each other in ways no one else can. This emotional connection then grows into a romantic relationship, and finally, they marry as they realize they don't want to be without each other.
It could be many characters. Maybe it was Videl. In the Dragon Ball series, Videl is a strong - willed girl, and she has a connection with Gohan. So in the fanfiction, it might be her that Gohan thought was cute.
Gohan may become more confident in relationships. In a harem situation, he has to deal with multiple people interested in him, which could boost his self - assurance.
Gohan will most likely encounter other Z - fighters like Krillin and Tien. They were all part of the group back then. Also, there's a good chance he'll meet Master Roshi. Roshi was a key figure in Goku's training, so his interaction with Gohan could be really interesting. He might also come across Bulma, who was always involved in the Dragon Ball story, either by accident or because he needs her help with some time - related technology or something.
One possibility is that it could be a genetic anomaly. Maybe something in his Saiyan genes that was dormant suddenly activated, causing the tail to grow back. In the Dragon Ball universe, Saiyan genetics are complex, and there could be some unexplored factors at play.
One possibility could be that in the fanfic, Android 18 sees Gohan's kind heart and strength. She might start to develop feelings for him as she watches him protect the Earth. Their relationship could be an interesting mix of her android nature and his Saiyan - human hybrid nature.
