One common theme is the clash of ideologies. Goku is all about protecting the innocent and having a fair fight, while Cell is more about self - preservation and domination at first.
One possible fanfic could be about Goku's intense training before the Cell Games. He might be shown pushing his limits in the Hyperbolic Time Chamber, trying out new techniques and forms to defeat Cell. Maybe he discovers a new power level that no one, including himself, expected.
It could be someone from Goku's past who has a vendetta against him and takes advantage of the chaos during the Cell Games. For instance, an old enemy who was thought to be defeated but managed to come back stronger and wants to finish Goku off while he's weakened from the fight with Cell.
One possible plot could be a story where Goku meets a female version of Cell who has different motives than the original Cell. Maybe she doesn't want to destroy the Earth but instead is on a journey of self - discovery. Goku, being the protector, is initially cautious but then starts to see her potential for good.
Well, if Goku was the legendary Super Saiyan in fanfiction, it could completely change the power dynamics in the Dragon Ball universe. There might be new enemies or allies formed based on this twist.
The adaptation of the kaioken concept within the bdeku context is crucial. It's not just about slapping the kaioken power onto bdeku. Writers need to think about how it fits into the existing lore and character design. This might involve creating new rules or limitations for the power in the fanfic world. Also, the fanfic often showcases bdeku's growth as a character. He might start off struggling to control the kaioken power but gradually master it, which is a common and engaging theme.
