Dragon Ball Super vs GT in fanfiction can lead to some really interesting character developments. The different timelines and power systems in both series offer a lot of room for creativity. In some fanfictions, the younger characters from Super might meet their older counterparts from GT. This can create a contrast in personalities and fighting styles. For example, Trunks in Super is more used to the modern power-ups and technology, while Trunks in GT has a more 'old - school' approach. Fanfic authors often use these differences to create engaging stories that explore not only the battles between the two series but also the underlying themes and character growth.
One possible scenario could be Satan trying to train Buu to become a 'good' fighter in the sense of human values. He might introduce Buu to things like sportsmanship, which would be really funny considering Buu's nature. Buu might initially be confused but then start to adapt in his own strange way.
Buu the Demonkin was a character in the Dragon Ball series, not in Dragon Ball Super or any other works. Buu the Demonkin first appeared in the fourth game of the Dragon Ball series, Dragon Ball Z: Buu. He was a very powerful villain with the ability to transform into both human and demon forms.
They often interact as powerful allies. They respect each other's strength since they are both the result of fusing two extremely strong Saiyans. For example, they might exchange fighting techniques or strategies.
Regular Dragon Ball fanfiction usually focuses on battles, power - ups, and the main storylines from the original series. However, Vegito harem fanfiction centers around relationships. It's more about the emotional connections between Vegito and the multiple characters in his harem. The focus shifts from fighting villains to exploring the interactions and romances within the group.
In Dragon Ball Super, the Demon Buu was a very powerful villain with combat power comparable to the Super Blue Warrior. However, the author did not let Buu participate in the power conference because he wanted to show Buu's different side and show his confrontation with other characters.
The participants of the Strength Contest were all trained and strengthened warriors. Their combat strength was very high. However, Buu the Demonkin was not a trained and strengthened character. His combat power was far from that of ordinary people, so he could not participate in the Strength Conference.
In addition, there are some contradictions and problems in the story. His existence itself is a kind of contradiction, so the author does not want him to participate in the power conference, but hopes to show his existence and influence through other means.
It's hard to say. Goku in Dragon Ball Super has Ultra Instinct which gives him incredible speed and reflexes. But in GT, his Super Saiyan 4 form is also extremely powerful. However, if we consider the fact that Ultra Instinct seems to be a more refined and spiritual form of power, it might give Goku in Super an edge. But then again, the Super Saiyan 4 form has its own advantages like the combination of Saiyan and Great Ape power.
