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.
In the fanfiction, Gildarts could meet Natsu and Igneel during a time of crisis. Maybe their town is under attack. Gildarts would immediately jump into action, and Natsu would follow suit, with Igneel guiding Natsu from the side. Gildarts might be impressed by the way Natsu and Igneel work together, as if they share a single mind. They could communicate without words, and Gildarts would try to learn from their unique bond. After the battle, Gildarts would offer to train Natsu further, seeing his great potential enhanced by his connection with Igneel.
Well, one possibility is that Gildarts could share some of his powerful magic techniques with Natsu. Since Gildarts is a very experienced wizard, he might see the potential in Natsu and offer some tips on how to better control his fire magic, which is similar to Igneel's. Maybe he could also tell Natsu some stories about his own adventures that would inspire Natsu to become even stronger.
Natsu could try his all - out offensive with his most powerful fire attacks. He might start with his Fire Dragon's Roar and then quickly follow up with a combination of punches and kicks enhanced with his fire magic. Another strategy could be to use his environment. If they're in a place with flammable materials, he can set them on fire to create distractions or additional sources of power for his attacks.
Gildarts would probably win. He's one of the strongest mages in Fairy Tail. His magic is very versatile and his strength is off the charts. Natsu is strong, no doubt, but he's still young and has a lot to learn. In fanfiction, the writers might be tempted to make it a close fight, but realistically, Gildarts' skills and power level are much higher. He's faced much tougher opponents and come out on top.
When thinking about who would be stronger in a 'Goku meets Natsu' fanfiction, we need to look at various factors. Goku's power levels keep increasing as he faces stronger opponents. He has the Kaio - ken technique and the super Saiyan transformations. Natsu, on the other hand, gets stronger as he eats more fire and overcomes difficult battles. His dragon force mode is one of his most powerful states. In a one - on - one battle, if it were in a wide - open space, Goku's long - range energy attacks might give him an edge. But if they were in a more enclosed, heat - based environment, Natsu could potentially use the surroundings to his advantage. Also, the strength in this fanfiction could be determined by the story's needs. If the writer wants to show the power of friendship and combined strength, they could make it so that neither is stronger alone, but together they are unstoppable.
It's really hard to say. Naruto has his chakra and all those powerful jutsu. But Natsu has his dragon - slayer magic which is also extremely strong. In a fight, it would depend on the situation, like the location and what kind of powers they can use at that moment.
Well, it depends on the specific fanfiction. There are various interpretations out there. Some fanfictions focus on Naruto's growth after the original series and give him abilities like super - charged chakra control or the ability to nullify Madara's strongest jutsu. However, in the original canon, Madara is an extremely powerful opponent. But in fanfiction, the rules can be bent to make Naruto stronger.
Well, it depends on the specific fanfic. Some fanfictions might give Naruto an edge over Madara by, say, having him master some super - secret jutsu that completely nullifies Madara's powers. Or they could boost Naruto's physical and chakra capabilities to an extent where he can easily defeat Madara. However, in the original Naruto lore, Madara is an extremely powerful foe, but fanfic authors have the freedom to change the power balance as they see fit.
