Another plot could be that a mysterious entity bestows the power of Super Saiyan Blue on Naruto. He then has to keep it a secret from his friends and village while also using it to protect them from a new and powerful enemy. This would create a lot of internal conflict for Naruto as he tries to balance secrecy and heroism.
One great Super Saiyan Blue Goku crossover fanfiction is 'Goku in the DC Universe'. It's really exciting to see Goku interact with Superman and other DC heroes. He has to adjust to the different power levels and rules in that universe.
Sure does. Goku attains the perfected SSJB in the manga during intense battles and as part of his power-up journey. It's a significant moment for his character development.
Well, it could be a really wild and interesting concept. Imagine Naruto with the power of Super Saiyan Blue. He would be incredibly strong, his speed would be off the charts. His rasengan might even take on a blue glow and have the explosive power of a Saiyan attack. Maybe he could also fly around the Hidden Leaf Village like a Saiyan, which would surely shock all his friends and foes alike.
Well, an interesting plot could involve a fusion of the energy systems in both Naruto and Dragon Ball universes. Naruto, as Super Saiyan Blue Naruto, could be tasked with saving both universes from a threat that is causing the boundaries between the two to collapse. He would have to use his newfound powers, which combine chakra and ki, to stop the chaos and restore balance.
The fanfiction should also do a great job of blending the two universes. Let's say it's a Goku and 'One Piece' crossover. The power - scaling, the different races, and the overall aesthetics of both universes need to be combined in a seamless way so that it feels like a natural and exciting story.
A new, self - created android by Dr. Gero's successor could be the main villain. This android could be specifically designed to target and defeat Super Saiyan Blue users. It could have the ability to absorb their energy and use it against them, making it a very difficult enemy for Goku and Vegeta to face.
One idea could be Ash getting transported to the Dragon Ball universe and somehow obtaining the power of Super Saiyan Blue. He could then use his Pokémon training skills combined with this new power to fight off powerful villains in the Dragon Ball world.
