In 'naruto godlike dc fanfiction', from the DC side, Superman and Batman are likely to be prominent. Superman's god - like powers in the Naruto world would be a huge change, and Batman's intelligence and combat skills could make him a formidable force among ninjas. Wonder Woman could also be a great addition as her warrior - like nature could fit well in the Naruto universe.
For Naruto side, Naruto himself is very likely. His determination and growth arc can be interestingly combined with DC elements. Also, Sasuke with his powerful Sharingan could have some cool interactions in the DC universe.
Iruka Sensei could also be a prominent character. He was an important figure in Naruto's early life. In a second - chance story, he might play a role in guiding Naruto in new ways, or perhaps Naruto could use his second chance to repay Iruka's kindness in a more significant manner.
Sasuke would be a likely character. He already has a dark past and a tendency towards brooding and seeking power, which would fit well in a 'world of darkness' setting. Orochimaru is another one. His experiments and his general amorality make him a natural for a darker Naruto story. And of course, Madara Uchiha. His grand and often cruel plans for the ninja world would be further explored in a darker fanfiction.
Tony Stark could also be a key figure in some fanfics, even though he's no longer alive in the main MCU timeline. His intellect and previous experiences with multiversal - related events (like in Endgame) could be explored in the fanfic. Maybe the Avengers find a way to access his knowledge or even a version of him from another universe to help them out.
Steven is the core, and among the Gems, not only the Crystal Gems but also Bismuth could potentially be part of it. Bismuth has a strong personality and her own connection to Steven. She could bring a different kind of energy to the harem. Also, Connie could be involved in some way, perhaps as a rival or a friend who helps Steven navigate his relationships with the Gems. Her human perspective could add an interesting layer to the story.
Naruto is a very likely character. Given his rebellious nature and his history of being an outcast in some ways, it's easy to imagine a scenario where he gets caught up in something that lands him in prison. His determination to break free and his loyalty to his friends would make for an interesting story.
Naruto and Ruby are very likely to interact. Ruby is the main character in RWBY, and Naruto being the central figure in his own story, their paths would surely cross. Ruby's enthusiasm for combat and her leadership qualities could make for an interesting dynamic with Naruto's determination and his own brand of leadership. Also, Weiss could interact with Naruto. Given Weiss's strict upbringing and her proficiency in combat, her reaction to Naruto's unorthodox ninja techniques would be fascinating.
Natsu would be a likely candidate. He's always eager for a fight and his reactions to the intense battles in Death Battle would be interesting.
Rock Lee could be an interesting character in this kind of fanfiction. He could use the Ninja Wire in his taijutsu - based combat, adding an extra element of surprise. Gaara might also be a good choice. He could use the wire in combination with his sand, perhaps using it to control the movement of his sand in more precise ways. Hinata could use the wire to enhance her gentle fist style, allowing her to strike from a greater distance while still maintaining the chakra - flow - based attacks.
Well, characters like Jiraiya could be really interesting in a 'naruto crossover godlike fanfic'. He has a lot of knowledge about the ninja world and different powers, so his encounter with god - like beings would be full of potential for interesting stories. Tsunade too, as a powerful Hokage, could be involved. She could represent the Naruto world's power structure when dealing with these otherworldly god - like entities. And then there's Orochimaru, who is always seeking more power, so he would be very likely to get involved in any situation where there are god - like powers to be had.
Sasuke would likely be featured. Since he and Naruto have a deep bond, Sasuke might be involved in Naruto's decision to retire or in filling the void left by him. Also, Naruto's family, like Hinata and his kids, would be important characters. They would be part of Naruto's post - retirement life, showing how they support him or how they are affected by his new lifestyle.
