There could be a really interesting fanfiction where Harry Potter, Vegeta from Dragon Ball Z, and Piccolo end up in a stadium. Maybe they are forced to compete in some sort of magical - martial arts tournament. Harry could use his magic skills, like the Patronus charm to fend off attacks, while Vegeta and Piccolo show off their powerful energy blasts and combat techniques. The stadium would be filled with excited fans from all their respective universes, creating a really chaotic but exciting scenario.
One way is to have a magical accident. Maybe a wizard in the Harry Potter universe was experimenting with interdimensional travel and accidentally brought Vegeta and Piccolo to the stadium in the wizarding world. Then they all have to figure out how to get back to their own worlds while dealing with the chaos that ensues in the stadium, like angry fans or other magical creatures that are attracted to the strange energy.
A 'bardock vs king vegeta fanfic' could explore the backstories of both characters. Bardock's story as a Saiyan who starts to question the Frieza regime might contrast with King Vegeta's more traditional and perhaps self - serving rule. Their fight could be a symbol of the changing tides within the Saiyan community. It could also introduce new elements to the Dragon Ball lore, like different forms of Saiyan power that are unique to this fictional encounter.
In a fanfic, Naruto might power up by having a spiritual awakening. He could connect with the spirits of past Hokages in a deeper way, gaining their knowledge and some of their power. This could enhance his existing jutsu and give him new abilities. Vegeta could power up if he were to face a near - death experience against Naruto. This could trigger a hidden potential within him, like a new type of Super Saiyan form that has unique abilities. He could also fuse with another Saiyan (if there were another Saiyan available in the fanfic's scenario) to create an even more powerful being.
Another theme could be loyalty. Bardock might be loyal to the true potential of the Saiyan race while King Vegeta is loyal to the existing power structure. This difference in loyalty can create a great conflict in the fanfic. Also, there could be a theme of social change. As Bardock may represent the underclass Saiyans who want a change, and King Vegeta is the symbol of the old regime.
In many fanfics, it's really hard to say for sure. Android 18 has her android strength and durability. Vegeta, on the other hand, is a powerful Saiyan with his Super Saiyan forms. If the fanfic writer focuses on Android 18's infinite energy, she could potentially outlast Vegeta. But if Vegeta quickly ascends to a high - level Super Saiyan form like Super Saiyan Blue, his power could be overwhelming.
Well, an ego trip in this story might be about the character's pursuit of things that boost their own ego. It could be achieving certain goals just for the sake of feeling superior or getting recognition. For example, if Dexter in the story is constantly trying to outdo others in his work not for the actual value of the work but just to satisfy his ego.
