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.
Sure. However, the quality can vary greatly. Some might be really well - written with detailed character development and exciting plots that incorporate the Super Saiyan God concept into the Naruto story seamlessly. Others might be more of a quick and fun read that just focuses on the action aspect of Naruto having this new power.
One reason this type of fanfiction is so appealing is the potential for epic battles. Percy, with his sword and water - based powers, combined with the Super Saiyan God's energy attacks, could face off against some truly formidable foes. And not just in terms of physical combat, but also in strategic battles where he has to use both sets of powers cleverly. Also, the cultural clash between the two worlds can add a lot of humor and interesting plot points.
