In many Dragon Ball Super fanfictions, Gohan's character development can take various directions. Some fanfictions might focus on his return to his Saiyan warrior roots. For example, he could start training intensively again after realizing the threat to his family and the universe. This would involve him pushing his limits in combat and rediscovering his latent powers.
Another aspect of his character development in fanfiction could be his role in the scientific community. Gohan is smart, and fanfictions could expand on his scientific research. He might use his knowledge to develop new techniques or even find ways to enhance the powers of his friends and family. This could also lead to him being in a unique position to deal with threats that require both scientific and martial arts knowledge.
Goku's understanding of different universes and races could be deepened in fanfiction. Since Dragon Ball Super introduced the multiverse concept, fanfiction could explore how Goku interacts with and learns from beings from other universes, making him more worldly and less naive in some ways.
In a fanfiction, Gohan as Super Saiyan 3 could be involved in a time - travel adventure. He travels back to a crucial point in Dragon Ball Z history and has to use his Super Saiyan 3 powers to change certain events. This could lead to a whole new timeline where things are different. For example, he might be able to prevent the destruction of Planet Namek or save some characters who originally died.
One idea could be Gohan in his Super Saiyan 4 form facing a new, powerful enemy from another dimension. He could struggle at first to control the raw power of this form while also trying to protect his friends and family. Maybe this new enemy has the ability to nullify the Saiyan's energy attacks, forcing Gohan to rely more on his martial arts skills that he learned from Piccolo.
Sun Wufan had many performances in Dragon Ball Super. According to the setting, Gohan had entered the Super Saiyan Stage 2 in the Saru chapter. At that time, he reached this stage before the main character Sun Wukong. This could be said to be his peak moment. However, in the world of Dragon Ball Super, he could even be killed by a gun. His status and strength had changed. According to the official settings, his daughter, Xiaofang, was a mixed-blood Saiyan because Gohan's mother was an Earthling. Her bloodline was not pure. In addition, Beadley was also an Earthling, which further weakened her Saiyan genes. Therefore, whether it was in the original story or in Dragon Ball GT., Xiaofang could not transform. In addition, in the original story, the God Rice (a state of Sun Wufan) was the strongest individual character (excluding the combined character). However, this state would continue to weaken, which meant that the potential development effect of the old King God would gradually disappear.
Sun Wufan's Super Saiyan 2 form was an important transformation form in Dragon Ball. In the Sarroux Game, Cyborg No. 16's epiphany allowed him to break through his limits and transform into Super Saiyan 2. In the final battle with Sharu, he defeated Sharu in the form of Super Saiyan 2. Other characters who could transform into Super Saiyan 2 were Sun Wukong, Vegeta, Future Trakus, Kaliphra, Gaga, Kefra, and so on. This form appeared for the first time in the manga Dragon Ball, and appeared many times in Dragon Ball Z, Dragon Ball MT, Dragon Ball Super, and Dragon Ball Hero. It also derived many enhanced forms (only counting the original Dragon Ball, series animation, series theater version, excluding games, non-Shueisha published manga (such as Dragon Ball AF.), non-Toei produced animation).
In fanfiction, Gohan could have an encounter with a wolf in many ways. Maybe the wolf is a magical or mutated creature in a story where Gohan has to protect the forest it lives in from some greater evil. The wolf could also be a spirit guide of sorts, leading Gohan to a new power or a hidden place full of secrets.
Family relationships are also a big theme. His relationship with Videl, his daughter Pan, and of course his father Goku. Fanfictions often explore how Gohan balances his family life with his role as a Z - Fighter. For example, there could be stories about how he teaches Pan about her Saiyan heritage while also dealing with threats to the Earth. There are also stories that focus on his relationship with Goku, like how Gohan continues to be inspired by his father or how they train together to face a new powerful enemy.
One idea could be Gohan struggling to control the new power of the Super Saiyan God. He might accidentally cause some destruction while training and then have to deal with the guilt and the fear of his power getting out of control.
They could go through a period of misunderstanding. Maybe Gohan makes a decision about his future that Chichi doesn't initially understand. Through communication and some trials, they grow closer as they learn more about each other's perspectives.
Gohan could be developed by showing more of his academic side in fanfiction. He's smart, and this could be explored further. For example, he could use his intelligence to create new techniques or solve problems that the Z - fighters face. Videl, on the other hand, could be developed by showing her growth as a martial artist outside of just learning from Gohan. She could travel to different dojos and learn from other masters, which would make her an even more formidable fighter in the fanfiction.
