The theme of legacy is quite common. Goku is a legendary figure, and in fanfiction, his legacy - what he leaves behind for future generations - is often explored. Also, the theme of redemption can be found. Maybe Goku made a mistake in the fanfiction's plot, and he has to redeem himself. And the concept of the hero's journey is also there. Goku's path as a hero, with its challenges, growth, and revelations, is a recurring theme in serious Goku fanfiction.
Well, he could discover new magical abilities or knowledge. Since Hogwarts has a vast curriculum, when Harry gets serious, he may delve deeper into subjects like Ancient Runes or Arithmancy, unlocking secrets that were previously overlooked. This could also lead to him making new friends who share his new - found academic interests. For example, he might become closer to Hermione in a different way, as they study more advanced topics together. He could also start to influence his classmates to take school more seriously as well, creating a positive academic environment in Gryffindor.
Yes, in the vast world of fanfiction, there are all kinds of creative and out - of - the - box stories. Some fans like to explore unusual relationships and scenarios, so it's possible that there is such a fanfiction out there. However, it goes against the original canon of the Dragon Ball series in many ways.
One great serious Goku fanfiction is 'Goku's Redemption'. It delves into Goku's inner struggles after a major battle where he made some tough decisions. Another is 'The Trials of Goku' which focuses on his journey to master a new form while dealing with the politics of the Saiyan race. And 'Goku's Ascent' is also worth reading, where he tries to reach a new level of power to protect his family and the Earth.
It could be Vegeta. Maybe Vegeta does something really underhanded like stealing Goku's senzu beans or trying to take all the credit for a victory that Goku also contributed to. Goku, being a fair - minded person, would get angry at such behavior.
His anger often manifests physically. His muscles might bulge more than usual, and his hair could stand on end even more in his Super Saiyan forms. His ki, or energy, also becomes more visible and intense. It's like a red - hot aura surrounding him.
Goku might adapt slowly at first. He's used to his own way of life on Earth and in the Dragon Ball universe. But his determination would help. He would learn the rules and schedules just like he learned new fighting techniques.
Naruto's character would become more disciplined. Goku's strict training regime would instill a greater sense of self - control in Naruto. He'd be less impulsive in battles.
There may be such fanfics in the vast world of fan - created content, but it often goes against the original storyline's intended relationships in the Dragon Ball series. In the official story, Goku is married to Chi - Chi, not Bulma.
He becomes more responsible. Instead of getting into as many impulsive adventures, he focuses on his studies and the duties that come with being a student at Hogwarts.
