Tsunade could interact with Midoriya Izuku. Izuku is always eager to learn new things and improve his skills. Tsunade could see his determination and potential, and she might teach him some of her combat and medical knowledge. Maybe she would help him control his quirk better or give him some physical training tips.
Another character she could interact with is Recovery Girl. Since they both have medical skills, they could exchange knowledge and techniques. Tsunade could introduce some advanced medical ninjutsu to Recovery Girl, and in return, Recovery Girl could show Tsunade how quirks are used in the medical field in the BNHA world.
A Tsunade crossover in BNHA fanfiction could involve her being from a different world but getting involved in the BNHA universe's affairs. She might end up in a fight against some of the villains. Given her short temper, she could be quite a force to be reckoned with. She could also form alliances with some of the heroes like All Might, sharing her knowledge of combat and medicine.
One interesting pairing could be Midoriya and Spider - Man. Both are young heroes who are constantly striving to prove themselves and have a strong sense of responsibility. They could learn a lot from each other's experiences and fighting styles.
Midoriya would be a great candidate. He has a strong sense of determination and is always eager to learn. He would approach Pokemon training with the same enthusiasm he has for becoming a hero. He would study each Pokemon's strengths and weaknesses carefully and form strong bonds with his Pokemon through his kind and empathetic nature.
Well, it could be really cool. Maybe the heroes from Boku no Hero Academia and the Avengers would team up to fight a common super - villain. For example, All Might and Captain America could lead the charge, with their strong sense of justice and leadership. The quirks of the BNHA characters combined with the powers of the Avengers would make for some epic battle scenes.
In a crossover with 'Sailor Moon', Sailor Mars would be a great character for kagome to interact with. They both have powers related to spiritual energy and fire. They could learn from each other's combat styles and magical abilities, and perhaps team up to fight a common enemy that threatens both their worlds.
Tanjiro and Deku would be a great pairing. Tanjiro's strong sense of justice and determination to protect his loved ones is similar to Deku's. They could learn a lot from each other, with Deku showing Tanjiro about quirks and Tanjiro teaching Deku about breathing techniques. Another interesting pairing could be Bakugo and Inosuke. They both have a fiery temper and are very competitive. Their interactions would be full of energy and probably a lot of arguing at first.
Goku would probably be really excited to meet Naruto. He'd be interested in Naruto's ninja skills and might ask to learn some of them. Naruto would be in awe of Goku's power at first but would quickly warm up and see him as a friend. They'd likely start by comparing their abilities and then team up to face a common threat.
Naruto might be very curious about Gwen's powers. He would probably ask a lot of questions and be eager to see how her magic works. Gwen, on the other hand, would be interested in Naruto's ninja way. She might be a bit cautious at first but would soon warm up to him.
Naruto would likely be very friendly towards Maleficent at first. He's used to befriending those who seem different or outcast. Maleficent, on the other hand, would probably be more guarded. She's been through a lot and is not quick to trust. But Naruto's persistent kindness might start to break down her walls.
Inuyasha would probably be very wary of Sephiroth at first. Inuyasha is used to dealing with demons and his own set of problems in his world. Sephiroth's otherworldly power and cold demeanor would make Inuyasha see him as a potential threat. He might even attack first out of instinct.
