Supergirl has super strength which allows her to lift extremely heavy objects. She also has heat vision that can be used as a weapon. And of course, she can fly. Wonder Woman, on the other hand, has super strength as well, but she has unique weapons like the Lasso of Truth which can force people to tell the truth, and her indestructible bracelets which can deflect bullets.
Supergirl could potentially win. She has the same powers as Superman under a yellow sun. Her heat vision can be extremely powerful. If she uses her speed and heat vision in a coordinated way, she could overpower Wonder Woman. Also, Supergirl might be more adaptable in different environments as she has had to face various threats on Earth and in space.
The use of alternate universes is also popular. In an alternate universe, Supergirl could have different powers or a different personality, and the same goes for Doomsday. This allows for unique and unexpected storylines where the outcome of their battle is completely different from the mainstream comics or shows.
In Thor vs Iron Man fanfictions, a really interesting plot twist is when the two are forced to work together against a common enemy. They start off as rivals but then realize that they need each other's skills. Another popular twist is when there is some sort of time - travel or alternate dimension involved. Maybe Iron Man travels to a time when Thor was a young and inexperienced warrior, or Thor finds himself in a dimension where technology is far more advanced than in Asgard and he has to adapt quickly to face Iron Man. These plot twists keep the fanfiction fresh and exciting for readers.
Well, it really depends on how the fanfiction is written. If the story focuses on Iron Man's technological advancements and his ability to quickly analyze and counter Thor's attacks, he might have a chance. However, Thor's raw power is not to be underestimated. He has centuries of combat experience and his powers are magic - based, which could potentially bypass Iron Man's technological defenses. So, more often than not, Thor has the upper hand.
There are also fanfictions where the battle is a draw. Maybe they fight to a standstill, or some external factor intervenes, like another superhero coming in and stopping the fight before there's a clear winner. The beauty of fanfiction is that it can take different directions depending on the writer's creativity.
Supergirl is a popular character in fanfiction. Writers love to explore her powers, her dual identity, and her relationships. Her superhuman abilities make for exciting action scenes, and her kind heart makes her a beloved hero in many stories.
If Barry kidnapped Supergirl in fanfiction, it could be a really interesting plot twist. Maybe Barry has been affected by some sort of red kryptonite - like substance that makes him act out of character. This would lead to a conflict between the Flash and Supergirl's friends and allies. They would be confused as to why Barry would do such a thing.
