Jiren could still be a tough opponent in the 'vegito tournament of power fanfiction'. His power level is extremely high, and he has great combat skills. Even for Vegito, defeating Jiren would be no easy feat as Jiren has proven his strength time and again in the original tournament.
In crossover fanfiction, Vegito Blue often brings a powerful and exciting element. His character combines the strengths of Goku and Vegeta in a unique way. For example, his combat skills and strategic thinking are enhanced due to the fusion. Writers can use him to create epic battles against various foes from different fictional universes.
One aspect of Vegito and Female Gogeta fanfiction could be the exploration of their unique power combinations. In these fanfictions, writers might create scenarios where they team up against a powerful enemy. For example, they could face a new, extremely strong villain that neither could defeat alone. Their combined strength and different fighting styles would make for an exciting story.
The Super-Reflected Being was a key core card in the Explosive series, and also the most outstanding single card in the Harmonization system. It could be used anywhere from 6 to 9 stars. The Super-Reflectors could be used as synchronization materials. After leveling up, they could summon other powerful monsters at the same time, such as the Flame Paladin Emperor Charlie, the Gun Gun Fierce Dragon, or the Psy Skeleton King Omega. In some Dark Magic Decks, Super-Reflectors were also used to compress the deck so that the key cards were easier to use. Although the strength of the Super Reflectors in the game was very high, to use it, one needed to stuff some useless cards into the deck as a price. All in all, the Super-Reflected was a very powerful and common card, widely used in different card sets.
In many popular crossover fanfictions, Vegito Blue is often the key to turning the tide in battles. His presence alone can shift the power balance. For example, in a crossover with the Naruto universe, his overwhelming power could be a huge threat to the ninja world.
Another theme is self - discovery. Many fanfictions show the female Vegito exploring her identity, especially since she is a unique fusion character. She may question her place in the Dragon Ball universe and gradually find her purpose through her adventures.
One common theme is power comparison. Writers often explore how Vegito's power from Dragon Ball stacks up against the powers in the other crossover universe, like the magic in a Harry Potter crossover or the quirks in a My Hero Academia crossover.
Maybe it's because Bulma has her own established character traits and relationships in the original story. She might not fit well into the scenarios often presented in Vegito fanfic. Also, her character is more focused on other aspects like her scientific work and family in the canon, so fanfic ideas involving her in a Vegito - related context could seem out of place to her character.
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.
