Another cool combination would be Bulbasaur and Wonder Woman. Bulbasaur's plant - based powers could be used in creative ways in combination with Wonder Woman's lasso and super - strength. Maybe Bulbasaur could create vines to help Wonder Woman in combat or she could protect Bulbasaur while it uses its powers to heal or create barriers.
The combination of Hulk and Superman would be really interesting. You have two extremely powerful beings. Superman's moral compass and the Hulk's uncontrollable rage would create a great dynamic. They could have a friendly sparring match where Superman has to figure out how to hold back the Hulk without hurting him. Or they could team up against a powerful foe, with Superman using his flight and heat vision while the Hulk does his smash attacks.
Definitely Harry Potter and Batman. Harry has his own set of skills dealing with magic and the dark arts, while Batman is a master strategist and detective. They could learn a lot from each other. Batman could teach Harry about non - magical combat and investigation techniques, and Harry could introduce Batman to the world of magic.
Definitely Pikachu and Batman. Pikachu's cute yet powerful appearance would contrast with Batman's dark and brooding nature. Batman could use his detective skills to figure out the mysteries in the Pokemon world, while Pikachu's electric attacks would be useful in combat. Also, the dynamic between them would be really interesting, like Pikachu trying to cheer up Batman or Batman trying to train Pikachu in a more strategic way.
Wonder Woman and Ron Weasley could be an interesting combination. Ron is often underestimated but has a lot of heart and loyalty. Wonder Woman, with her strength and noble character, could inspire Ron to be more confident in himself. Ron could introduce Wonder Woman to the fun and sometimes chaotic side of the wizarding world. They could work together to fight off enemies, with Ron using his magical skills and Wonder Woman using her combat and leadership skills.
I think Thor and Wonder Woman would be really interesting. Thor is a god from Asgard with his hammer Mjolnir and control over lightning, while Wonder Woman is an Amazonian princess with her Lasso of Truth and super strength. Their different mythological backgrounds would make for some great exchanges and potential team - up action.
Superman and Cyclops. Superman is the ultimate symbol of hope and power in the DC universe, while Cyclops is a strong and strategic leader among the X - Men. Their different approaches to leadership and power could create an interesting dynamic.
Definitely Alex Mercer. His powers are so unique compared to the Justice League members. He can shapeshift into anyone, has superhuman strength, and can regenerate from almost any injury. This would create a lot of interesting interactions with the League. For example, he could transform into Superman to test the limits of his own power against the real Superman, which would lead to a really cool showdown.
Goku and Superman would be an amazing pairing. They are both incredibly powerful and have a strong sense of justice. Their different power sources, ki for Goku and the sun for Superman, could lead to some really interesting interactions. They could compare their strength limits and maybe even train together.
Batman would be a great character to focus on. He doesn't have superpowers like the others but his intelligence and strategic mind are his greatest assets. In a 'Justice League Infinity War' fanfic, he would be the one trying to figure out the complex nature of the Infinity Stones, coming up with plans to outwit Thanos. He might also have some tense moments where he has to rely on the super - powered members of the League in ways he's not used to, which could lead to some great character growth and interesting interactions.
Definitely Ben and Batman. Batman would be intrigued by Ben's Omnitrix and his ability to transform into different aliens. He would try to analyze it while Ben would be in awe of Batman's detective skills and gadgets. It would be a clash of two very different mindsets - one a young, impulsive hero and the other a brooding, strategic one.
