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.
It's hard to say, but Goku would be a top contender. His ability to constantly power up and reach new levels of strength like Super Saiyan God and Ultra Instinct is insane. But Ben in his Alien X form from the Omnitrix also has near - omnipotent powers. So it could really go either way depending on how the fanfiction writer sets up the battle conditions.
It's a bit tricky to say for sure. Some might argue it's Beerus, the God of Destruction. But Goku and Vegeta also have insane powers and keep evolving. It really depends on your perspective and which point in the manga you're looking at.
It's likely to be Goku. His ability to reach Super Saiyan levels and beyond gives him an insane amount of power. In comparison, even the strongest quirks in My Hero Academia seem relatively weak. Goku's combat experience and his constant pursuit of getting stronger would make him a dominant force in the merged universe.
There are no such inappropriate 'Straight Shota' stories in the official Dragon Ball Z canon. Dragon Ball Z mainly focuses on epic battles, power-ups, and the adventures of Goku and his friends to protect the Earth from various villains.
In this crossover fanfiction, determining the strongest would be complex. Saitama's power is a mystery even in his own universe. He doesn't seem to have a limit. Goku, on the other hand, is always pushing his limits and reaching new levels of power. Vegeta could also be a factor. His pride and determination might lead him to try and take on Saitama. But Saitama's lack of interest in prolonged battles might make it difficult for any DBZ character to fully gauge his strength. So, it's really hard to say who would be the strongest in this crossover.
It's a tough call. Goku has the ability to keep getting stronger through training and achieving new forms like Ultra Instinct. However, Saitama has shown that he can defeat any opponent with one punch so far. But Goku's powers are more defined in terms of levels and growth potential. So, it's hard to say who would be the strongest in a crossover. It could depend on the situation and how the writer wants to portray their encounter.
Dragon Ball Z is both anime and manga. The anime was adapted from the manga and they share the same story and characters, but presented in different mediums.
