Goku's Saiyan powers, like his Super Saiyan forms which boost his strength, speed, and energy output, could combine with Captain Marvel's energy - based powers. For instance, if they were to perform a joint attack, Goku could charge up a large amount of ki energy while Captain Marvel adds her photon - based energy. The result could be an extremely powerful blast that could take out even the toughest of enemies.
It could lead to epic battles and team-ups. Goku's super strength and energy attacks would mix with Marvel's heroes and villains in exciting and unpredictable ways.
A plot could involve Goku and Captain Marvel being on opposite sides of a moral dilemma. For example, Goku might be more focused on a pure battle for the sake of getting stronger, while Captain Marvel is more concerned with protecting the innocent. This conflict could lead to some intense battles between them at first, but then they discover a greater threat that makes them see eye - to - eye. Also, they could be in a story where they are both summoned to a strange new world and have to rely on each other to find a way back home. Maybe they find a powerful artifact there that has the power to change the balance of power in their respective universes.
Well, Vegeta would be a likely character. He might be initially suspicious of the female Goku. Maybe he thinks she's a threat or just can't believe there's another Goku - like being. He could be there to add some comical moments as he tries to understand the situation.
In general, it's a bit of a toss-up. The strength of Manga Goku and Anime Goku can vary depending on the specific arcs and battles. Sometimes, it might seem like one is stronger in a particular situation, but that could change in another.
Another possible main character could be the villain that forces the two Gokus to meet. This villain could be a new, super - powerful threat that the two Gokus need to deal with. Their meeting becomes a crucial part of the story to defeat this powerful foe.
It could be insanely powerful. Goku already has incredible power levels, and Goku Black is no slouch either. When they fuse, it's like combining two nuclear reactors. Their power could be so great that they could effortlessly destroy planets just by flexing their newfound power. They might be able to reach Super Saiyan forms that are far beyond what we've seen in the official series, with power levels that are basically off the scale.
