It depends on how the author of the fanfiction has developed the plot and the characters. They could have given Natsu some special power - up or a unique situation that makes him stronger than Gildarts. For example, the author might have introduced a new form for Natsu that gives him an edge in combat, or perhaps they've weakened Gildarts in some way for the sake of the story. However, in the original series, Gildarts is extremely powerful, so this is a significant departure in the fanfiction.
There probably is. Fanfiction is a vast world where all kinds of ideas are explored. Since Naruto and Jiren are from different anime universes, a fanfiction about Naruto being a fan of Jiren could be really interesting. It might involve Naruto somehow learning about Jiren's power and being in awe of it. Writers could play around with different scenarios like Naruto trying to train like Jiren or even seeking his advice in the fanfiction world.
Yes. In many fanfics, Naruto is often depicted as stronger than Jiraiya. Naruto has the potential to grow far beyond his master. He has unique powers like the Nine - Tails chakra and has mastered many advanced jutsu over time, which can make him stronger in fan - created storylines.
In the comics, it's not a straightforward yes or no. Sometimes Hulk shows immense strength, but Thanos often has other powers and strategies that give him an edge.
Yes, Thanos is typically stronger. His powers are not just physical but also include energy manipulation and a vast intellect that makes him a more formidable opponent than Hulk.
In most comic storylines, it's a bit of a toss-up. Sometimes Hulk has raw power on his side, but Thor has his magic hammer and godly abilities. So, it depends on the specific context and plot.
In the comic world, it's hard to say for sure. Thor is physically powerful, but Wanda's magic is unpredictable and can tip the scales. Different comic arcs might show one as stronger than the other.
