Who are the most likely characters to be featured prominently in 'naruto world of darkness fanfiction'?

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.

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.

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.

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.

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.

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.

Sasuke would likely be one of the main characters to interact with Naruto. Given their complex relationship, Sasuke might be either supportive or skeptical of Naruto's newfound power. Sakura could also be involved, perhaps trying to heal Naruto if the dark power has negative effects on him. Kakashi would surely step in as well, using his wisdom to guide Naruto and make sure he doesn't lose himself in the darkness.

Naruto himself is very likely to be featured. He's the main character after all.
