A crossover could start with Wonder Woman being summoned to Asgard by some mysterious magic. She finds herself in a strange new world and is initially met with suspicion. Thor, being the more open - minded of the Asgardians, decides to help her figure out how she got there. Along the way, they discover that an ancient enemy from Thor's past has plans to use Wonder Woman's power to open a portal to a realm full of chaos. They then have to work together to stop this from happening, with Wonder Woman teaching Thor some new combat techniques she learned on Themyscira and Thor showing her the power of the Asgardian magic.
One key difference is their origin. Hercules is from Greek mythology, a demigod born from a god and a mortal. Wonder Woman is from the fictional island of Themyscira. Also, their powers are different. Hercules is mainly known for his extreme physical strength. Wonder Woman has super strength too, but also has powers like flight, and the ability to use her Lasso of Truth.
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.
In certain comic arcs, Mighty Thor does meet his demise. However, comic storylines can be complex and sometimes characters are brought back or their deaths have significant plot implications.
In the origin story, Thor is a powerful Asgardian. He is the son of Odin, the All - Father. Thor is known for his great strength and his mighty hammer, Mjolnir, which is a symbol of his power.
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.
Thor's lightning power could be combined with Wonder Woman's bracelets. For example, Thor could channel his lightning through her bracelets, creating a more powerful defensive or offensive weapon. It would be like a super - charged energy blast that could take out powerful enemies.
A plot could involve a magical rift that transports Thor to Wonder Woman's world. He doesn't understand the ways there at first and causes some chaos. Wonder Woman has to step in to keep the peace and teach him about her world. In the process, they discover a threat that is targeting both their realms and must combine their powers to defeat it. For example, Thor's lightning and Wonder Woman's lasso could be used in a unique way to counter the enemy's magic.
In a 'Thor meets Wonder Woman' fanfiction, perhaps they meet in a neutral realm. Thor is intrigued by Wonder Woman's connection to the Greek gods while she is curious about his Asgardian heritage. They get involved in a tournament of sorts where they have to team up against other powerful beings. During this time, they share stories of their heroic deeds. Thor tells her about his battles against the Frost Giants and Wonder Woman shares her tales of protecting the world from Ares. By the end of the tournament, they exchange gifts - Thor gives her a small Asgardian charm and she gives him a piece of Amazonian armor.
