Wonder Woman and the Hulk would also be an interesting pair. Wonder Woman is a fierce warrior herself. She could try to understand the Hulk's anger and perhaps relate it to her own experiences in battle. They could fight side - by - side, with Wonder Woman's lasso and sword skills complementing the Hulk's raw power. Maybe she could even teach the Hulk some self - control techniques, while the Hulk shows her a different way of using brute force in combat.
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.
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.
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.
I think Naruto would be the most interesting. His boisterous personality and powerful ninja abilities would stand out in the Justice League world.
Definitely Superman. He has the strength and the moral compass to try and understand the Hulk. He can also withstand the Hulk's attacks to a certain extent, so he could be the first to approach the Hulk and attempt to form an alliance. He might see the good in the Hulk, similar to how he sees the potential for good in Lex Luthor at times.
Batman and Iron Man would be a fascinating pairing. Both are brilliant inventors and strategists. They could compare their high - tech gadgets and suit designs. Batman's detective skills paired with Iron Man's scientific knowledge could make them a formidable duo in solving the mystery of some cross - universe threat. They might also argue about who has the better tech, which would be quite entertaining.
The interaction between Superman and Supergirl would be really interesting. They share the same Kryptonian heritage but have had different experiences on Earth. Superman could act as a mentor to Supergirl, or they could have a friendly competition to see who is stronger in different situations.
Definitely Superman and Master Chief. Superman has all his superpowers like super strength, flight, and heat vision, while Master Chief is a highly trained super - soldier. They could have an interesting dynamic, with Superman respecting Chief's combat skills and Chief being in awe of Superman's powers. They could work together to take on powerful enemies, like Darkseid if he somehow got involved in the Halo - Justice League crossover.
Rorschach and Batman would also be a great pair. They are both dark, brooding characters who are very dedicated to their own versions of justice. They might start off clashing due to their different methods, but eventually find common ground in their pursuit of truth.
Wonder Woman could be the most interesting. Her Amazonian training and warrior skills would make her a natural fit in the Jaeger - fighting world. She could also bring her lasso of truth and bracelets to the fight. Maybe she could use the lasso to restrain a Kaiju or figure out some of their secrets. And her strong sense of justice would mesh well with the overall theme of the crossover.
I think Thor and Superman would be a very interesting pairing. Thor is a god with his hammer and lightning powers, while Superman is an alien with super strength, flight, and heat vision. They could have some great battles testing their strength and then team up to take on a powerful foe like Doomsday or Ultron. Their different personalities, Thor's more brash and Superman's more moral, would also create an interesting dynamic.
