Wonder Woman is also very powerful. She has superhuman strength, combat skills, and her Lasso of Truth can force people to tell the truth. Her bracelets can deflect attacks. She is a key member in battles. Well, she comes from an island of powerful Amazons and her powers are a combination of her divine heritage and training.
The Justice League typically includes well-known heroes like Superman, Batman, Wonder Woman, The Flash, Green Lantern, Aquaman, and others. These characters form the core team.
I think Flash himself would be really interested. After all, it's about him. He'd be curious to see how the writer of the fanfiction portrays his character, his powers, and his relationships with the other members of the Justice League.
It's really hard to say. Naruto with his godlike powers would be extremely powerful. He can do things like create massive Rasengans and has near - unlimited chakra. But Superman in the Justice League also has incredible strength, speed, and heat vision. He can fly at supersonic speeds and is nearly invulnerable. However, if Naruto's godlike form gives him the ability to manipulate time and space like some of the Otsutsuki in his world, he might have an edge over Superman.
It's hard to say for sure, but Superman could be a top contender. His super strength, speed, and flight, along with his heat vision and other abilities, make him extremely powerful. He can withstand a lot of damage and dish it out just as well.
In my opinion, it could be Scarlet Witch. Her reality - warping powers are extremely potent. In a crossover, she could potentially change the very fabric of the combined universes. If she were to go rogue or be influenced by an evil force, she could cause chaos on a scale that would be very difficult for the combined might of the Justice League and the Avengers to handle. Even Superman's invulnerability might not protect him from her reality - warping abilities. She could simply make him mortal or take away his powers altogether.
Well, if we consider the power of the gods in Percy Jackson's world, Zeus could be considered the most powerful. But in a crossover fanfiction, he might not be directly involved. Among the main characters, if we look at it from a different perspective, Batman could be considered very powerful. He doesn't have superpowers in the traditional sense but his intelligence, gadgets, and strategic planning could give him an edge. He could find a way to neutralize the powers of both Percy and the Justice League members if he needed to. So, it really varies depending on how you define power.
The Mother Boxes are really cool. They have the power to do various amazing things like terraforming and energy manipulation.
In my opinion, Martian Manhunter could be considered pure science fiction. His alien origin, shape-shifting powers, and psychic abilities are typical of sci-fi elements.
Batman is often a very popular character. In fanfiction, he can be portrayed in different ways, like a more nurturing mentor figure to the Young Justice team or as a master strategist leading the Justice League in complex battles.
One of the most powerful is the Precursors from the 'Halo' series. They have god - like powers in terms of technology and genetic manipulation. They were able to create entire species and civilizations, and their technology is far beyond that of any other species in the game universe.
