If Vegito never unfused, it might mean that the enemies he faced were simply not strong enough to force the separation. This could imply that the story's difficulty level was lower than originally thought. Or, it could be that some external factor prevented the unfusing, creating a whole new set of plot twists and complications.
I'm not directly part of the Xeno Forum's success story, but I can imagine that if I were, it would be because of the great networking opportunities. Meeting like - minded people who are into Xeno - stuff would be amazing. You could collaborate on projects, exchange knowledge, and even become friends.
Some dedicated Dragon Ball fan communities on social media platforms might also be a good source. For example, certain groups on Facebook or Reddit where fans discuss and share their fanfiction works. However, the availability of exactly this pairing might vary. You may need to do some searching within those communities.
The success might also lie in its management. Good moderators who ensure the rules are followed, keep the conversations civil, and promote healthy discussions can make a huge difference. They can also organize interesting events or threads that keep the members engaged. For instance, they could start a monthly 'Xeno - theory of the month' discussion where members can share their wildest ideas about Xeno - related things.
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.
It gives a chance for creativity in exploring gender - swapped or alternate versions of the characters. Fanfiction writers can play with the personalities and backstories of these characters in ways that the original series might not have explored. For example, they can write about how the female Vegito might approach a relationship with Gogeta differently than a male Vegito would, adding new layers to the story.
In some fanfictions, Gogeta and Vegito might find themselves in a different dimension where the rules of power and combat are different. They would need to adapt quickly. For example, they may lose their ability to fuse at will and have to rely on their individual skills more. This would lead to a great character - development arc for both of them as they learn to fight in new ways.
A great plot twist might be that Po discovers he has some hidden connection to Tai Lung. For example, they could be related in some long - lost family way. This would add a whole new layer to their relationship and the story. Po would then have to grapple with the idea of fighting someone who is, in a way, family, and Tai Lung could use this knowledge to his advantage in different ways during their confrontations.
If Vegito stayed fused, it's likely that he could have overpowered the villains with his combined strength and skills. There might have been fewer challenges and a quicker resolution to the conflict.
It could lead to some really unique storylines. Maybe Vegito would have to face challenges alone that he'd normally handle fused. This would test his individual skills and strategies to the max.
