Who could be the one to betray Goku in 'Goku betrayed fanfiction'?

It could be Vegeta. Maybe in this fanfiction, his pride gets the better of him and he feels overshadowed by Goku and Gohan's power. So he fabricates some lies to make them look like traitors to the rest of the group.

Vegeta could be a likely character. In some fanfictions, his pride and envy of Goku's strength might lead him to betray Goku. He might think that by getting rid of Goku, he can become the strongest in the universe. Another one could be Frieza. Even if he pretends to be an ally in some alternate storylines, he could betray Goku at a crucial moment to regain his power and dominance. Also, a new and powerful character introduced in the fanfiction, who is envious of Goku's popularity and power, could easily be a betrayer.

Perhaps in the fanfiction, an evil version of Goku from an alternate timeline arrives. This impostor causes chaos and destruction, but everyone blames the real Goku. His family and friends are deceived by the look - alike. Goku tries to prove his innocence but no one will listen. He might have to find a way to expose the impostor and regain the trust of those he loves.

In the 'goku and gohan betrayed fanfiction', perhaps they are betrayed due to a misunderstanding. Say, Goku makes a deal with an unknown force to save the universe, but it's misconstrued as him allying with the enemy. Gohan, being associated with Goku, is also seen as a traitor. And this misunderstanding could be spread by a character with their own motives, like a power - hungry individual who wants to take over the Z - fighters' leadership.

It could be a new, self - created villain. This villain might have been training in secret for years, specifically to defeat Goku. He could have studied all of Goku's moves and weaknesses and then launch a surprise attack that causes Goku to get hurt.

It's hard to say. Adult Goku has more experience and has achieved higher power levels. But Kid Goku has an unbridled potential that could make him a formidable opponent even to his adult self.

It could be Zamasu. Since Goku Black was Zamasu in Goku's body in the original story, perhaps a more powerful and enraged Zamasu could be the main antagonist. He might be jealous of the new fused form's power and seek to destroy it.

Maybe it's a new character created specifically for the fanfiction. This character could be a powerful sorcerer who has the ability to manipulate people's minds. He targets Goku out of jealousy for his power and popularity. By using his mind - control powers, he makes everyone around Goku believe that he's a traitor, thus making himself the main antagonist.

It could be a jealous camper. Maybe someone like Clarisse, who has always had a bit of a rivalry with Percy. She might see an opportunity to get rid of him and make herself look better in the eyes of the camp. So, she could plant false evidence or spread lies that lead to Percy's betrayal.

It could be Gray. Although they are friends most of the time, in a fanfiction, there could be a plot twist where Gray's envy of Natsu's abilities gets the better of him, and he betrays Natsu. Maybe Gray thinks that by getting rid of Natsu, he can be the top mage in their guild.
