I think Hulk has a better chance. His raw power is immense, and he often overcomes challenges with brute force. The Leader might have plans, but Hulk's strength could overpower them.
It's hard to say for sure. Hulk has immense strength, but Batman is extremely smart and strategic. It could go either way depending on the circumstances.
It depends on the situation. If Naruto has access to his full power, like the Six Paths Sage Mode and can use all his ninjutsu skills, he could potentially outmaneuver the Hulk. He could use clones to confuse the Hulk and then hit him with a powerful Rasengan. But if the Hulk gets really angry and reaches his World - Breaker level of strength, he might be able to overpower Naruto with his sheer brute force.
Well, in the bat man vs superman story, it depends on the context. If we consider a fight in Metropolis where Superman has all his powers and no kryptonite around, Superman is going to be very difficult to beat. He can zip around the city, dodge Batman's attacks, and use his super strength to overpower Batman. But if Batman manages to get his hands on kryptonite, like he did in some versions of the story, then the tables can turn. Batman is a master strategist, and with kryptonite, he could potentially incapacitate Superman. However, overall, Superman has the natural advantage due to his superhuman abilities.
Kratos might win. He has fought and defeated many powerful gods in his own world. He is not only physically strong but also very strategic. He could analyze the Hulk's movements and find his weaknesses. The Hulk, while strong, is more of a brute force fighter. Kratos could use his Blades of Chaos to keep the Hulk at a distance and then strike when the opportunity arises. Also, Kratos has faced opponents much larger than him before and has always found a way to win.
It's really hard to say. Harry Potter has some very powerful magic at his disposal. He could potentially use a spell to send the Hulk to another dimension or something. But the Hulk's raw power is so great. If he got his hands on Harry, it would be over. So, it could go either way depending on how the fanfiction is written.
In some fanfictions, the winner isn't really about who is more powerful physically or technologically. It could be about who has the stronger will or the better moral compass. For example, if Iron Man realizes that he's in the wrong during the fight, he might back down, making Spider - Man the 'winner' in a sense. Or if Spider - Man is able to convince Iron Man of a greater good, the fight could end without a clear physical victor.
