It depends on the specific fanfiction. In some stories, Superior Iron Man might be more powerful because he's willing to push the limits of his technology and his morals further. But in others, Iron Man could be more powerful due to his experience and his ability to work well with others.
Often, villains from both Iron Man and She - Hulk's rogues galleries can be popular in fanfiction. For Iron Man, it could be characters like Mandarin or Obadiah Stane. For She - Hulk, villains like Titania might show up. Their presence creates conflict and gives the heroes something to fight against, which drives the plot forward. And let's not forget characters like Happy Hogan, who can add some humor and a down - to - earth perspective to the stories.
One interesting storyline could be Iron Man and She - Hulk teaming up to fight a new, powerful villain that neither could defeat alone. They combine their unique skills, with Iron Man's high - tech gadgets and She - Hulk's brute strength.
One storyline could be them collaborating on a new project to improve the Avengers' base. Iron Man uses his engineering skills and Hulk uses his strength to build new structures or defenses. This shows their cooperation and mutual respect without any sexual undertones.
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.
In some fanfictions, they might team up against a common enemy that requires both their unique skills. For example, a new super - villain who has the ability to hack into Iron Man's technology and also has super - strength that Spider - Man has to counter with his acrobatic fighting style. They would have to learn to work together, with Iron Man respecting Spider - Man's instincts and Spider - Man learning to trust Iron Man's strategic plans.
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.
The differences between them are significant. Lex Luthor is more of a traditional villain in the short story. He is jealous of Superman mainly and wants to prove his superiority through his intelligence and inventions. His technology is sometimes more experimental and untested. Iron Man, however, is a hero who has refined his suit over time. His technology is reliable and battle - tested. In terms of character, Iron Man is more self - sacrificing. He is willing to put himself in danger to protect others. Lex Luthor is more concerned with his own status and power. Their methods of achieving their goals are also different. Iron Man uses his technology to directly combat threats, while Lex Luthor may use more underhanded means like manipulation and subterfuge.
Iron Man would probably win. He has a highly advanced suit with a plethora of weapons and defensive systems. His suit is constantly evolving and he has the genius of Tony Stark behind it. Metallo, while strong with his kryptonite - powered body, Iron Man could analyze his weaknesses and use his repulsors, missiles and other gadgets to take him down.
One interesting plot could be where Metallo somehow gets an upgrade that can disrupt Iron Man's technology. Then Iron Man has to rely on his wits and basic engineering skills to fight back. Another could be a scenario where Iron Man has to protect a city from Metallo without using his full - powered suit, making it a more challenging fight.
