Well, perhaps in an alternate universe where the Naruto world and DC universe somehow cross paths. Naruto, being a father, might have been introduced to DC superhero stories by his kids or maybe he stumbled upon some DC comics during his travels. He could be drawn to the complex characters and their moral dilemmas in the DC universe.
He might be interested in Batman. As a father, Naruto could relate to Batman's protectiveness over Gotham, which is similar to how he wants to protect his family and village. Batman's use of strategy and his determination in the face of danger could also be appealing to Naruto.
Friendship and cooperation is also a major theme. Many fanfictions depict Naruto forming bonds with DC superheroes. They might start off as strangers or even enemies but end up working together to face a common threat. This shows how characters from two very different universes can come together for a greater good.
One interesting storyline could be Naruto teaming up with Batman. Naruto's energetic and straightforward nature would contrast with Batman's brooding and strategic style. They could combine their skills to take on a powerful villain that neither could defeat alone, like a new type of ninja - themed super - criminal in Gotham City.
Naruto and Batman are a popular pairing. Their different personalities and similar goals of protecting their respective worlds make for an interesting dynamic. Batman can learn from Naruto's unwavering spirit, and Naruto can gain knowledge from Batman's detective skills.
There's also 'The Ninja of Gotham' which is really cool. In this fanfiction, Naruto finds himself in Gotham City. He has to deal with the likes of the Joker and Batman while also trying to find a way back to his own world. The way his ninja abilities contrast with the technology in Gotham makes for a great read.
It depends on personal preference. Some people might like Marvel superheroes more for their diverse powers and relatable characters. Others might prefer DC superheroes for their classic and iconic status.
A lot of people also like the fanfictions that explore the relationship between Wonder Woman and other heroes in a more in - depth way. For example, a story where she has to train a new generation of female heroes. It's inspiring and showcases her leadership skills.
Your male OC could be a meta - human with the ability to control electricity. He was an ordinary electrician who got caught in a freak accident involving a kryptonite - powered generator. This accident gave him his powers. In your fanfiction, he could start off as a reluctant hero, not fully understanding his powers. He might cross paths with Superman and learn from him how to use his powers for good, eventually becoming a part of the Justice League.
Plastic Man's origin in fanfiction often varies. In some, he might be an experiment gone wrong in a scientific facility. His abilities include extreme elasticity, which allows him to stretch his body into various shapes and sizes. He can also mold himself into objects, like a key to unlock a door or a parachute to slow his fall.
