I'm not entirely sure what '187 fac fac not fiction' specifically means. '187' is often associated with the California penal code section for murder in some contexts, but 'fac fac' is really unclear. 'Not fiction' just implies it's not made - up, but without more context, it's hard to give a definite meaning.
Sorry, I can't really explain it in more detail as 'fac fac' is so unclear. All I can say is that '187' has that potential connection to the law and 'not fiction' means it's not a made - up concept. But without knowing what 'fac fac' means, it's tough to go further.
Fac could represent a family (F) issue, an accident (A) or a character flaw (C). In a true love story, any of these could lead to a super sad outcome. For instance, if family disapproves of the relationship and forces them apart, or an accident changes one of them so much that the other can't handle it, or a character flaw like jealousy ruins their love.
Well, it could be about a couple who face (fac) insurmountable obstacles in their relationship. Maybe one of them has a terminal illness, which makes the story super sad. Their love is true but the situation is tragic, like they are separated by society's norms or family issues.
Well, Vegeta would be a likely character. He might be initially suspicious of the female Goku. Maybe he thinks she's a threat or just can't believe there's another Goku - like being. He could be there to add some comical moments as he tries to understand the situation.
In general, it's a bit of a toss-up. The strength of Manga Goku and Anime Goku can vary depending on the specific arcs and battles. Sometimes, it might seem like one is stronger in a particular situation, but that could change in another.
Another possible main character could be the villain that forces the two Gokus to meet. This villain could be a new, super - powerful threat that the two Gokus need to deal with. Their meeting becomes a crucial part of the story to defeat this powerful foe.
One of the characters who could betray Goku is Piccolo. Although they've been allies for a long time, in fanfiction, things can change. Perhaps an ancient evil force takes control of Piccolo's mind and makes him turn on Goku. Or it could be Krillin. He might be influenced by an outside force that convinces him Goku is becoming too dangerous. Also, don't forget about the Kais. If there's some sort of power imbalance or a threat they perceive from Goku, they might betray him to maintain the order of the universe in the fanfiction.
