Who would be the most interesting character to crossover between 'Dragon Ball Z' and 'High School DxD' in a fanfic?

One possible plot could be that the characters from Dragon Ball Z end up in the High School DxD world and have to deal with the different power dynamics and social hierarchies there. For example, Goku could be intrigued by the way the devils and angels in High School DxD have their own unique powers and politics. He might try to learn from them while also showing off his Saiyan strength.

It's hard to say for sure, but Goku would be a very strong contender. His ability to keep increasing his power level through training and reaching new forms like Super Saiyan God and Ultra Instinct makes him extremely powerful. However, characters like Franklin Richards in the Marvel universe have reality - warping powers that could also be very hard to defeat. But if Goku were to fully master Ultra Instinct and combine it with the power of the Dragon Balls, he could potentially be the most powerful.

The interaction between Goku and Naruto would be really interesting. Goku is this pure - hearted, power - hungry Saiyan who loves to fight strong opponents. Naruto, on the other hand, has a strong sense of justice and a never - give - up attitude. They would probably start off by testing each other's strength and then realize they can learn a lot from each other. Another interesting interaction could be between Vegeta and Sasuke. Both are proud characters with a bit of an edge. They might initially clash due to their personalities, but could end up respecting each other's power.

Goku and Captain America would be really interesting. Goku is all about raw power and a simple - minded love for fighting strong opponents, while Captain America represents honor, strategy, and leadership. Their interaction could be fun, like Goku trying to understand Cap's sense of duty and Cap being in awe of Goku's power.

Another great pairing would be Weiss and Vegeta. Weiss is from a noble family and has a refined way of fighting, while Vegeta is a proud Saiyan prince. Their interactions would be filled with tension and mutual respect. Vegeta could teach Weiss about the power of Saiyan pride and she could introduce him to the more elegant fighting techniques of Remnant.

Vegeta is also popular. His prideful and brooding nature would be really interesting in a high school environment. He might be the loner who's secretly really powerful and has a soft spot for a certain girl at school.

Gohan could be really interesting. He has so much untapped potential. In a tournament, he could finally fully embrace his Saiyan heritage and show off new forms or techniques that we haven't seen before. He also has the added drama of trying to balance his academic life with his fighting responsibilities.

Well, if we consider that in the Sonic universe, there are characters like Shadow who has his own unique abilities and is very powerful. In a crossover, if he were to gain some of the Saiyan abilities like ki control, he could be a formidable force. But then again, Vegeta with his pride and combat experience wouldn't be one to back down. He might be able to figure out Sonic's speed patterns and counter them. So it's not easy to determine who would be the most powerful. It could also be a new character that emerges from the combination of the two universes' power sources.

It's hard to say, but Goku would be a top contender. His ability to constantly increase his power level and learn new techniques would make him a force to be reckoned with, even in a world with Pokemon. He could potentially use his Ki to enhance the abilities of any Pokemon he teams up with.

If we consider the potential of power - up in a crossover, it might be a new form of Goku. Imagine if Goku were to combine the power of the Saiyan God form with some of Devilman's demon - like abilities. He could become an entirely new and extremely powerful entity. But then again, Devilman has the potential to merge with other powerful demons in his world. So, in a sense, it could be either Goku with his new form or a super - powered Devilman depending on how the fanfiction unfolds.
