Thor could also be a very interesting character. His god - like powers and his noble nature would be a great addition. He could have some epic battles with the powerful foes in the Pirates of the Caribbean world, like Davy Jones. And his hammer would be a really cool weapon in the pirate - filled seas.
Captain Jack Sparrow would be really interesting. His wily and unpredictable nature would be a great contrast to the more straightforward superheroes of Marvel. He could trick them into all kinds of situations or team up with them in the most unexpected ways.
Harry Potter could be a great addition. He could use his magic to help or hinder the pirates. Maybe he gets accidentally transported to the Caribbean and has to figure out how to get back home while dealing with the likes of Captain Jack Sparrow.
It could be amazing. Picture Iron Man flying over the Black Pearl, using his repulsors against the cursed pirates. Maybe Captain Jack Sparrow tries to steal Thor's hammer for some wild adventure. And the Hulk could be running amok on one of the Caribbean islands, scaring all the pirates there.
The Arbiter and Thor. Thor is a powerful Asgardian with his hammer and lightning powers, while the Arbiter is a skilled warrior from the Halo universe. They could fight side by side against a common enemy. Their different cultures and fighting styles would make for an exciting combination. Maybe Thor could teach the Arbiter about magic, and the Arbiter could show Thor some unique Covenant combat techniques.
One of the most interesting pairings could be Kakashi and Barbossa. Kakashi's calm and collected nature, along with his vast array of ninja skills, would be an interesting match for Barbossa's greedy and cunning personality. They could be in a situation where they have to work together against a common enemy, like a powerful sea witch or a group of rogue ninjas who have found their way into the Pirates of the Caribbean world. And then there's Hinata and Anamaria. Hinata's shy yet strong character could befriend Anamaria, and they could have their own little adventures on the high seas, perhaps looking for a special kind of ninja - pirate treasure.
Definitely Superman and Captain America. They both represent the ideals of their respective universes. Superman with his superhuman strength and unwavering moral compass, and Captain America with his leadership and never - give - up attitude. Another interesting pairing would be Batman and Iron Man. They're both brilliant inventors and strategists, and seeing them compete or collaborate on a project would be fascinating.
Jack Sparrow is surely one of the most interesting. His wily and unpredictable nature makes him stand out. He's always got a scheme up his sleeve. Elizabeth Swann is also interesting. She starts as a proper lady but then becomes a strong and fearless pirate. Barbossa too, with his complex relationship with the curse and his own brand of pirate leadership.
Naruto and Spider - Man would be really interesting. They are both young heroes with a strong sense of justice. Naruto could learn some of Spider - Man's acrobatic moves and Spider - Man could be intrigued by Naruto's chakra - based powers. They could also bond over their experiences of growing up without parents in a way.
Iron Man would be really interesting. He could analyze the Bakugan technology and come up with some amazing upgrades for his suit using Bakugan elements. His witty personality would also create some great interactions with the Bakugan characters.
One idea could be a crossover with 'Peter Pan'. The pirates could sail to Neverland and have adventures with Peter, Tinker Bell and the Lost Boys. Maybe Captain Jack Sparrow would try to steal the fairy dust from Tinker Bell.
It's hard to say, but Thor could be a really powerful character in a Halo x Marvel crossover. He has his godly powers, like control over lightning and super strength. In the Halo universe, not many things can stand up to his power. He could easily take on Covenant forces or even some of the Flood with his hammer Mjolnir.
