Definitely, Cortana could be a main character in a 'halo anime crossover fanfiction'. If she were in the world of Code Geass, she could help Lelouch with his strategic plans, using her vast knowledge and intelligence. Another option is the Elites from Halo. They could be the main characters in a crossover with My Hero Academia. Their physical strength and warrior culture could be contrasted with the superheroes in that anime, and they could have some interesting interactions with the students at UA High.
Percy, with his powers over water, could be like a water - based ninja in an anime world. His impulsive nature would also add a lot of action and drama. Annabeth could be the smart strategist, similar to characters like Shikamaru from Naruto. Grover could be the comical sidekick but also have important roles like sensing danger in the anime world.
Sailor Moon is also a common choice. Her magical girl powers and positive attitude can bring a touch of light and hope to a crossover story. She can inspire other characters with her determination to protect the world.
Goku from Dragon Ball would be an excellent ally for Kirby. Goku is extremely powerful and has a lot of combat experience. He could teach Kirby some new fighting techniques, and together they could take on powerful foes. Goku's ability to go Super Saiyan and Kirby's ability to copy powers would make them a formidable team. Another great ally could be Naruto. Naruto's ninjutsu skills and his never - give - up attitude would complement Kirby well. They could work together to defeat enemies that are causing trouble in both their worlds.
In a Goku vs Broly crossover fanfiction, anime characters could have different reactions. Some might see Goku as a symbol of justice and be inspired by his never - give - up attitude. On the other hand, Broly's raw power could intimidate those who value brute strength. And there could also be characters who try to interfere in the fight for their own motives, like to stop the destruction that such a powerful battle could cause.
Definitely Hinata from 'Haikyuu!!' and Kuroko from 'Kuroko no Basket'. Hinata's energetic and explosive plays combined with Kuroko's almost invisible yet highly effective moves would make for some amazing on - court action.
Obviously, the fem Harry Potter would be one of the main characters. And perhaps she could meet Naruto in an anime world. Naruto's determination and her own magic skills would make them a great duo to face challenges together.
First, you can combine the traits of both. For example, if you have a pony from MLP crossing into an anime world like One Piece, you could give the pony some of the adventurous spirit of the Straw Hat Pirates. Maybe the pony is really good at finding hidden treasures now. Second, you can create new characters that are hybrids of the two universes. A half - pony, half - Naruto - style ninja could be really interesting. It would have the speed and stealth of a ninja and the magic of a pony.
One character that would be really cool to include is Edward Elric from Fullmetal Alchemist. His knowledge of alchemy and his quest for the Philosopher's Stone could cross paths with Naruto's search for power to protect his village. Also, Saitama from One - Punch Man. It would be hilarious to see Saitama's nonchalant attitude towards fighting in the world of Naruto, where battles are usually more intense and drawn - out.
He could interact with Ichigo from Bleach. Since Naruto is in a godlike state, their encounter would be really intense. Ichigo might be both in awe and on guard against Naruto's overwhelming power.
