Definitely Goku and Jiraiya. Goku's innocent nature and love for food and training would contrast with Jiraiya's more lecherous and laid - back but also very wise personality. Jiraiya would be intrigued by Goku's power and might try to write a new book about him. And Goku would be interested in Jiraiya's toad - related jutsu. Also, the encounter between Naruto's team and Gohan's friends could lead to some interesting dynamics. The younger characters from both sides could learn about friendship and loyalty in different ways from each other.
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 Luffy would be really interesting. Goku is all about pure strength and the pursuit of becoming stronger through training, while Luffy is more about the adventure and his dreams. Their different outlooks could lead to some great conversations and also some funny moments, like when Luffy tries to eat Goku's senzu beans thinking they are some kind of food from his world. Another interesting interaction could be between Vegeta and Zoro. Vegeta is very proud and serious, and Zoro is a swordsman with his own code of honor. They could have some intense sparring sessions and also respect each other's strength.
Well, Vegeta could also be a contender for the strongest in this crossover. He has his own set of powerful transformations. However, if we consider the more mystical aspects of Naruto, like the power of the Rinnegan, characters like Sasuke could also be very strong. In a crossover, if Sasuke were to combine his Sharingan and Rinnegan powers with some of the ki - based techniques from Dragon Ball Z, he could be extremely powerful. It really depends on how the writer wants to balance the different power systems.
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.
Goku and Asuka would be really interesting. Goku's simple - minded but powerful nature would contrast with Asuka's complex and somewhat arrogant personality. They could have some great banter and also learn from each other in terms of fighting spirit.
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.
Aizen Sousuke is another character from Bleach who could be in the running. His intelligence and his hogyoku - enhanced powers made him a formidable foe. In a crossover with Dragon Ball Z, if he were to face someone like Frieza, he could use his illusions and mind - games to gain an advantage. Frieza is powerful but not as mentally cunning as Aizen. However, if Frieza were to transform into his final form quickly and catch Aizen off - guard, Frieza could potentially win. So again, it depends on how the fight unfolds and who can utilize their powers more effectively.
Well, it could be Whis from Dragon Ball Z. He is an angel who is extremely powerful and has knowledge of many things. In a crossover, his powers would be far beyond what most characters in Bleach could comprehend. He could potentially manipulate the very fabric of the Bleach universe with his angelic abilities. Even compared to Goku and Ichigo, Whis' level of power is on a different scale. He could be the most powerful if he were to get involved in the events of the crossover.
