If they were in a battle together against a common foe, Naruto would be the one leading the charge with his powerful ninjutsu attacks. Clayface, on the other hand, could use his shape - shifting to create distractions or even form barriers to protect them. Naruto would be constantly communicating with Clayface, trying to come up with strategies that make use of both of their unique abilities. For example, Naruto could use his Rasengan while Clayface shapeshifts into a large creature to hold the enemy still for the attack.
In a more in - depth interaction, if Clayface were to get injured in the Naruto universe, Naruto could offer to help him. Naruto's knowledge of medical ninjutsu might be able to heal Clayface in some way. This would create a bond between them as Clayface would be grateful. They could then exchange stories about their respective worlds, with Naruto telling Clayface about his life as a shinobi and Clayface sharing his experiences in Gotham.
Well, if Naruto becomes Clayface, he would gain the ability to shape - shift like Clayface does. This could make him a more versatile fighter. He might be able to blend into the environment, spy on enemies more easily, or even create decoys of himself to confuse opponents during battles.
They could also have a mentor - mentee relationship in a way. Naruto, with his experience in combat and growth, could offer advice to Ophis on how to better control her power. Ophis, with her knowledge of the DxD world's magic and power systems, could teach Naruto some new skills or ways to enhance his chakra. This exchange of knowledge and experience would create a unique dynamic between them.
Naruto could be initially attracted to Frostmourne's power. He might touch it and start to feel a strange connection, but then quickly realizes the danger it poses.
In the fanfiction, Naruto could also team up with other characters from the Dementor - related world. He could combine his ninja techniques with their magic to combat the Dementors more effectively. For instance, he could work with a wizard who knows a lot about Dementors and together they could develop new strategies to keep the Dementors at bay. His ability to make friends and form strong alliances would be very useful in this scenario.
Another possibility is that Clayface somehow gets transported to the Naruto universe. The shinobi in the Naruto world would be very confused by his abilities. Clayface could try to blend in by mimicking the appearance of different shinobi, but his lack of chakra would give him away. Naruto might see through his disguise easily due to his own perceptive skills.
The story could start with Naruto being exposed to some strange new chakra or magic that transforms him into Clayface. At first, he might struggle to control his new form, accidentally scaring people in the village. But as he learns to master it, he starts to see the potential in his new abilities.
They could interact through a mutual respect for each other's powers. Naruto might be in awe of female Aquaman's ability to communicate with sea creatures and control the waters, while she could be impressed by his ninjutsu. For example, Naruto could use his shadow clone jutsu to help her herd a group of unruly sea monsters that are causing trouble near a coastal village.
Naruto's chakra - based powers and Maleficent's dark magic could either clash or combine. For example, Naruto could use his Rasengan, and Maleficent could add her dark magic to it, creating a super - powerful attack. Or their powers could be in opposition, like Naruto's life - affirming chakra against Maleficent's death - dealing magic.
Naruto would likely approach the pharaoh with his friendly and fearless attitude. Hinata, on the other hand, would approach with more caution and grace. The pharaoh may initially be aloof, but as Naruto shows his strength and Hinata shows her kindness, the pharaoh could warm up to them. They could interact in battles, with Naruto leading the charge, Hinata providing support, and the pharaoh strategizing. Outside of battles, they could have conversations about different ways of life, Naruto and Hinata introducing the pharaoh to their ninja world concepts, and the pharaoh sharing his ancient wisdom.
They could be enemies. Naruto, with his strong sense of justice, would see M. Bison's evil ways and immediately oppose him. Their interactions would be full of conflict, with Naruto using his ninjutsu like Rasengan against Bison's Psycho Power attacks.
