In some fanfics, Naruto can be made stronger than Goku. Fanfic writers have the freedom to manipulate the power levels and abilities of characters. They can give Naruto new and overpowered abilities that surpass Goku's. However, in the original canon of their respective series, Goku has extremely high power levels and abilities that are on a different scale.
One thing could be unique chakra abilities. If in a fanfic, Naruto discovers a new form of chakra that gives him unlimited power, he could be stronger. For example, a chakra that can nullify all energy - based attacks like Goku's ki blasts.
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.
It's a bit hard to say for sure. Both Vegeta and Goku have their moments of strength. Goku has some unique powers and techniques that give him an edge at times, but Vegeta is no slouch either and constantly works to catch up and surpass Goku.
In a Goku Naruto crossover, both characters have their own strengths. Goku's physical strength and energy attacks are off the charts. His ability to instantly teleport and sense ki gives him an advantage in combat. Naruto, though, has a unique power system. His connection to the Nine - Tails and his ability to use different types of chakra make him a force to be reckoned with. If we consider a battle, Goku's power might seem greater on the surface. But Naruto has the advantage of being able to surprise his opponents with his ninjutsu and clones. Also, Naruto has a strong willpower that has allowed him to overcome many tough situations, which could play a role in a fight against Goku.
Goku is known for his raw power and his ability to constantly increase his strength through training and battles. He can blow up planets with his attacks in his more powerful forms. Naruto, on the other hand, has the power of the Nine - Tailed Fox and his own unique ninja skills. But if we consider the fact that Goku can move at speeds close to the speed of light and has energy attacks that can obliterate entire solar systems, he might seem stronger. However, Naruto's ability to use shadow clones to outnumber his opponents and his Sage Mode which gives him enhanced perception and strength can't be ignored. It really depends on the situation and how the author of the fanfiction writes the encounter.
It's really hard to say. Goku has superhuman strength and can destroy planets with his power. But Spyro has his own set of unique abilities like flying, fire - breathing, and his agility. If it's a physical strength test, Goku might seem stronger. But in a world full of magic and different terrains, Spyro could have an edge in his own territory.
