In a straight - up power comparison, Goku has the ability to reach extremely high power levels that can destroy planets. But Naruto has the power of the Nine - Tailed Fox and his Sage of Six Paths mode which also gives him immense power. If the fight takes place in Naruto's world, Naruto could use the environment to his advantage, like summoning giant toads or using the terrain. On the other hand, if it's in a more open space like in Goku's battles, Goku could use his flight and long - range attacks more effectively. So it's hard to say who would win definitively.
In this kind of fanfiction, Naruto being 'godlike' gives him a huge advantage. He might have powers far beyond his normal capabilities. So, Naruto would likely win. He could use his super - enhanced Sage Mode, or maybe some new jutsu that he has acquired in this 'godlike' state to overpower Madara.
In a one - on - one fight between One Punch Man (Saitama) and Goku, it's really tough to say. Saitama is known for being able to defeat any opponent with just one punch. However, Goku has a vast array of powerful forms and techniques. If Saitama landed his first punch, he'd win instantly. But Goku's speed and ability to constantly power up could potentially give him an edge. He could keep dodging Saitama's punches until he found a way to overpower him. It really depends on how the fight is set up in the fanfiction.
Another theme is redemption. Sometimes in these fanfics, Madara has a chance at redemption through his fight with Naruto. Naruto's belief in people's goodness can influence the outcome in such scenarios.
One common theme is the underdog story. Sakura is often seen as the underdog against the powerful Madara. So, many fics focus on her struggle and how she overcomes the odds. Another theme is the exploration of power levels. Writers often play around with how Sakura could match up to Madara's immense power.
There are definitely some out there. However, the quality can vary greatly. Some fanfics might be written by novice writers and have grammar or plot issues. But if you dig deep enough, you can find well - written ones. You could also try joining Naruto - related fan forums and asking for recommendations. People there are usually quite helpful and can point you towards some great 'sakura vs madara fanfic'.
Sasuke is often a popular character in these fanfictions. He might play a role in helping Naruto against Madara or have his own motives during their battle. Kakashi can also be a prominent figure, perhaps using his Sharingan in a crucial moment to assist Naruto. Another popular character could be Hashirama, as his connection to Madara is a key part of the original story and can be further explored in fanfiction.
I think Black Goku might have the upper hand. He has shown to be extremely powerful and has some unique abilities. His Saiyan body combined with Zamasu's knowledge makes him a formidable opponent.
One interesting plotline could be Naruto discovers a new form that gives him an edge over Madara. For example, a form that allows him to nullify Madara's Sharingan abilities. Another could be Madara having a change of heart due to Naruto's unwavering belief in him. Maybe he starts to question his own motives for destruction.
