Thanos could also win in a fanfiction. He has incredible strength and the power of the Infinity Stones at his disposal. In a lot of fanfictions, the power levels are often exaggerated. Thanos could simply use the Reality Stone to make Iron Man's weapons ineffective or use the Time Stone to freeze Iron Man in time and then defeat him. His brute strength alone is enough to overpower Iron Man in a direct confrontation. And his experience in battles across the universe gives him an advantage over Iron Man who mainly operates on Earth.
The plot could start with Spider - Man accidentally getting transported to Thanos' home planet. There, he has to survive and find a way back to Earth while being hunted by Thanos. As he evades Thanos, he learns about the weaknesses of Thanos' power and technology. When he finally gets back to Earth, he uses this knowledge to fight Thanos and protect the planet.
Another storyline could be that Thanos, aware of One Punch Man's power, tries to use the Infinity Stones to either eliminate him or make him an ally. There could be a long - drawn - out battle where One Punch Man has to constantly dodge Thanos' attacks while trying to find a way to land his one punch. In the end, he manages to do it and saves the day.
One interesting plot twist could be that Iron Man discovers a hidden power within his suit that can counter the Infinity Stones. Maybe it was something he unknowingly built into it long ago.
In a Spider - Man vs Thanos fanfiction battle, it's tough to say who would win. Spider - Man has his agility, spider - sense, and web - slinging abilities. He can quickly dodge attacks and come up with creative ways to fight. However, Thanos is incredibly powerful, with his strength and the Infinity Stones (if he has them in the fanfic). But if Spider - Man could somehow use his intelligence to outwit Thanos, like finding a weakness in his armor or the way he uses the Stones, he might have a chance. It really depends on how the author of the fanfiction writes the encounter.
Well, in this graphic novel, Deadpool's wacky and unpredictable nature clashes with Thanos' power - hungry and often brooding demeanor. It makes for some really interesting and comical battles.
A possible plotline is that Thanos hears about the powerful chakra in the Naruto world and decides to conquer it. Naruto stands up to him, and during the fight, Naruto unlocks a new form of his power that is on par with Thanos' strength with the Infinity Stones. Along the way, Naruto teams up with some of his old foes who also realize the danger Thanos poses. They all fight together to protect their world.
The plot typically involves the Avengers facing off against Thanos. Thanos usually has some grand plan, like gathering the Infinity Stones to reshape the universe. The Avengers must come together, using their unique powers and teamwork, to stop him from achieving his malevolent goals.
One possible storyline could be that Thanos arrives on Earth seeking a powerful artifact. Superman steps in to stop him. They battle it out across the city, with Superman using his strength and speed to try and take down Thanos. Another could be that Thanos somehow manages to get Superman under his control using the Infinity Stones, and then the rest of the Justice League has to figure out how to free Superman and defeat Thanos.
