Theories based on hypothetical crossovers were made to amuse and entertain us for a while. Imagining what could happen if two universes come together is interesting, at least to create wonderful scenarios. Like this one where we put together Marvel Already dragon ball in a most preposterous situation.
Consider for a moment Krillin, Yamcha or Ten Shin Han becoming a Super Saiyan. It would be impossible, because, to achieve it, they would have to have the DNA of this race. And as we well know, the Dragon Ball universe shows them as humans.
However, if at some point Akira Toriyama and the heirs of Stan Lee decide to merge the worlds in a crossover, these three warriors could obtain the powers exclusive to Goku, Vegeta, Gohan, Goten, Trunks and Broly.
How? In an event of She-Hulk this possibility is explained in detail. Jennifer Walters, Bruce Banner’s cousin, obtains the powers of a Hulk due to an accident in which her relative’s blood got into her wounds.
So as far-fetched as it sounds, this could be possible in Dragon Ball with the Saiyans. Perhaps the only barrier is that the Hulk’s powers were obtained by a failed serum that tried to emulate Captain America’s abilities.
While that of the Saiyans is something native and not an experiment involving gamma rays. But in the Marvel comics there is even a planet of the Hulk’s, so this would open a door for this lunatic idea to be executed.
Remember that this is only part of the imaginative universe of crossovers that we frequently consider to have fun with the series that entertain us.
