Minato might also be a prominent character. As their teacher, he can influence the way Obito and Kakashi interact. In some fan fictions, he could be the one to help them resolve their differences or provide some crucial information about their past that changes their current situation.
Some fanfictions might explore the emotional aspect of their fight. For example, how their past friendship affects the battle. Maybe Kakashi hesitates to strike a fatal blow because of their shared history.
Well, 'perfect cell crossover fanfiction' could be about taking the character of Perfect Cell from Dragon Ball Z and crossing him over into different universes or storylines within the fanfiction world. It might involve him interacting with characters from other anime or even creating new scenarios and power - level battles.
One possible plotline could be that Cell, seeking to prove his superiority, challenges Broly. Broly, in his usual berserk state, accepts without hesitation. The fight could start with Cell trying out his various attacks like the Kamehameha - like Solar Flare and his physical strikes. But Broly's power is just too much and he starts to overpower Cell. However, Cell then reveals a new, hidden ability that he has been developing in secret and the tables are turned for a while.
In some fan fictions, there might be a plot where Obito has a change of heart before a major battle with Kakashi. He could start to question his motives and the path he has chosen, leading to a very intense and emotional confrontation with Kakashi that is more about ideology than pure combat.
One aspect to consider in Dragon Ball Z Perfect Cell fanfiction is the character development. Writers often explore Cell's potential for redemption or further evolution. For example, some fanfictions might depict Cell having a change of heart after his defeat, perhaps realizing the futility of his actions. Another interesting point is the power scaling. Fanfic authors might introduce new power - ups for Cell or the other Z - fighters, creating unique battles that we didn't see in the original series. Also, the relationships between characters can be re - imagined. Maybe Cell forms an unexpected alliance with a Z - fighter, which would completely change the dynamics of the story.
You could also check out Naruto fanfiction groups on social media platforms like Facebook. There are often enthusiasts who share and discuss their favorite fanfictions. Just search for relevant groups, join them, and then look for fanfictions about Kakashi vs Obito.
One interesting story could be about Cell somehow getting transported to the Naruto universe and having to adapt to the chakra system. Maybe he starts learning ninjutsu and forms unique combinations with his own powers.
One great Dragon Ball Z Perfect Cell fanfiction is 'Cell's Redemption'. It shows Cell having a change of heart and using his powers for good. Another is 'Cell in Another Dimension' which explores what would happen if Cell was transported to a different universe. There's also 'The True Power of Perfect Cell' which focuses on Cell unlocking new and unexpected powers.
Frieza could be a great antagonist. He might see Cell's power as a threat and try to eliminate him while the OC is caught in the middle. Frieza could also try to use the OC to his advantage against Cell, creating a complex web of power struggles.
