In a straight - up fight, Itachi has some very powerful abilities. His genjutsu can be extremely difficult to break out of, and his ninjutsu attacks are strong. But Batman is no slouch. He has fought against some of the most powerful villains in the DC universe. He would study Itachi's moves and try to find a pattern. Batman might also use his wealth to create some sort of countermeasure to Itachi's Sharingan. Overall, it's a very close call and would likely depend on how the writer of the fanfiction wants the story to go.
It's really hard to say who would win. Jiraiya has his Sage Mode which gives him enhanced strength, speed, and perception. But Pain has the Rinnegan which allows him to use powerful abilities like the Six Paths techniques. In the RWBY fanfiction context, it might depend on how well they adapt to the RWBY world. If Jiraiya can quickly figure out how to use Dust to his advantage, he might have an edge. But if Pain can use his powers to disrupt the balance of the RWBY world, he could also come out on top.
In most traditional interpretations, Itachi would be favored to win due to his long - established reputation as a powerful and feared ninja. But in the realm of fanfiction, the writer can tip the scales in Sakura's favor. For example, if Sakura has mastered some sort of anti - Sharingan technique or has a power - up that nullifies Itachi's main abilities, she could emerge victorious.
In a fanfic, it really depends on how the author writes it. But if we base it on the original series' power scaling, Naruto has a higher chance of victory. He has learned from many battles and has a wider range of abilities compared to Jiraiya. Also, Naruto has a strong will that could give him an advantage when facing his old master in the Edo Tensei form.
Hard to say for sure. Both Itachi and Sasuke had unique strengths in the manga. Maybe Itachi's experience would give him an edge, or Sasuke's raw power and drive could tip the scales in his favor.
Superman is extremely powerful on his own. His powers are almost god - like. But the Avengers have a lot going for them too. For example, Iron Man has his high - tech suits which can adapt to different threats. Captain America is a great strategist. In a fanfiction, it could depend on the circumstances. If it's a fight in an environment full of kryptonite, the Avengers would have an advantage. But in a normal battle, Superman's power might be too much for the Avengers to handle all at once.
Well, it really depends on how the fanfic is written. If the fanfic focuses on Naruto's weaknesses and Danzo's preparedness, Danzo could potentially win. He has a lot of political power and experience. However, if it follows the general power scale of the Naruto universe, Naruto has a better chance. His positive energy and the power of friendship (a bit cheesy but true in Naruto's world) often help him overcome his opponents. Naruto also has the ability to quickly adapt to new situations, which would be a big plus against Danzo.
