Gohan's power of transformation could be affected. Instead of turning Super Saiyan in the normal way, it could be related to the haki system in One Piece. Maybe his Super Saiyan form gives him a special type of haki that is unique and extremely powerful.
Gohan's powers would be quite unique in the Marvel Universe. His Super Saiyan forms would give him a massive boost in power, far beyond what most normal Marvel characters can achieve without some sort of external boost. His Zenkai boosts, which increase his power after near - death experiences, could also be an interesting concept to introduce. And his martial arts skills, combined with his Saiyan instincts, would make him a very adaptable fighter against the various threats in the Marvel world. He could also potentially teach other heroes his fighting techniques.
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's powers would probably be seen as extremely strange and almost magical to the ponies. His ability to fly without wings, shoot energy blasts, and his super - strength would be beyond their comprehension. They might initially be frightened of him, thinking he's some kind of dangerous being. But once they see he's there to help, they would be in awe of his powers and see him as a powerful ally.
Gohan's ki - based powers and Naruto's chakra - based powers could potentially interact in an interesting way. For example, Gohan's energy blasts might be enhanced by Naruto's chakra control, making them more precise and powerful. On the other hand, Naruto could use Gohan's ability to sense ki to detect hidden enemies or sense incoming attacks better. Maybe Naruto could even learn to use ki in addition to chakra by observing Gohan.
Gohan could become more of a leader. With the power of Super Saiyan 5, he would be one of the most powerful beings in the universe. Other Z - fighters might look to him for guidance and leadership. This could bring out a more assertive side of his personality. He would need to step up and make tough decisions for the greater good, which would shape his personality in a more authoritative way.
In a pregnant fanfiction, their relationship would grow deeper. There would be more emotional intimacy as they share the joys and fears of the pregnancy. Gohan might become more domesticated, helping Erasa with things like cooking and cleaning, which he may not have done as much before. Erasa would rely on Gohan more for emotional support, and they would have to communicate better to make decisions about the baby's future.
In this fanfiction, Gohan could be a new member of the Straw Hat Pirates. He would bring his unique skills like the Kamehameha wave. His strength would be a great asset during their adventures, especially when facing strong foes like the Yonko.
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.
Gohan's powers are on a different scale. His super strength and speed are not like the typical quirks in My Hero Academia. In a fanfiction, his ki attacks could be something completely new to the world. Quirks like Bakugo's explosion quirk might seem less impressive next to Gohan's full - power kamehameha. But at the same time, quirks that manipulate elements could potentially interact with Gohan's ki in interesting ways. For instance, a water - based quirk could be used to enhance or counter Gohan's ki attacks depending on how it's used.
If Gohan dies in the Cell Games in fanfiction, Goku and Chi - Chi's relationship would be severely strained. Goku might blame himself for not being able to protect their son, and Chi - Chi would be heartbroken and potentially angry at Goku. Vegeta's relationship with Goku could also change. He might respect Goku more for his pain, or he could become more competitive, vowing to never let his own family be in such a position.
