It could be someone who wants to use Naruto's unique heritage against him. Maybe a villain from the Naruto universe who sees Naruto's connection to Harley Quinn as a weakness. For example, Orochimaru might want to capture Naruto to study his strange combination of powers.
Perhaps Naruto is raised in a world where both the Naruto and DC elements are combined. He grows up learning ninjutsu but also has a penchant for Harley Quinn - like pranks. His story could be about him trying to bring peace to this mixed - up world. He uses his Rasengan in new and creative ways, like adding some of Harley's acrobatic flips to his attacks. And he has to deal with villains who are also a combination of Naruto - style bad guys and DC villains.
It could be someone who wants to use Naruto's connection to the scar for their own evil purposes. Maybe a rogue ninja who believes that the scar holds some kind of dark power that can be harnessed.
It could be a rogue ninja who has a vendetta against Naruto. This ninja might see Naruto's son as a way to get back at Naruto for past defeats or slights.
One main theme is the clash of cultures. Naruto comes from a world of ninjas with honor and strict codes, while Harley Quinn is from the chaotic Gotham. Their interactions often highlight this difference.
Harley Quinn would be the central figure. Then there could be a powerful inmate who rules a part of the prison. This inmate could have a complex relationship with Harley, which ties into the 'lemon' aspect, like a love triangle with another character. And don't forget the warden, who could be constantly trying to keep Harley in line but is always outwitted by her.
The concept of this fanfiction is an exciting blend of two very different aesthetics. Naruto is all about the traditional Japanese ninja look and feel, with its focus on discipline and spiritual power. Harley Quinn is the epitome of a modern, Western - style anti - hero/villain. In a fanfiction, they could exchange their skills. Naruto could show Harley how to focus her energy like chakra, and Harley could show Naruto some of her street - smart tricks. They could also have some really interesting conversations about their different views on life, love, and what it means to be a hero or anti - hero.
Well, for a Naruto and Harley Quinn fanfiction, it could start with Harley Quinn somehow ending up in the Naruto universe. Imagine her reaction to all the ninjutsu and the shinobi way of life. She might find it both fascinating and a bit too rigid compared to her life in Gotham. Naruto, on the other hand, would be curious about her unique style and her unpredictable nature. They could team up against a common enemy, perhaps an evil ninja who has some connection to Harley's past villains in her own universe. Their different fighting styles would make for some great action scenes in the fanfiction.
It could be Orochimaru. He's always after power and seeing Naruto with Son Goku's power would make him a prime target. He might try to extract the power from Naruto for his own evil experiments.
The story could start with a strange portal opening in Gotham City. Out comes Naruto, all confused about this new and dark place. Harley Quinn, who was just about to cause some trouble, sees Naruto and is intrigued. She approaches him, not knowing what to make of this strange - looking boy with orange clothes and a headband.
Well, in fanfiction, anything can be possible. Maybe some sort of multiverse theory could be applied. A strange rift in the fabric of the universes could have occurred, pulling Naruto from his ninja world into Harley Quinn's chaotic Gotham - like world. And then, through some really wild and unthinkable circumstances, they end up in a situation where Naruto could be seen as her son. Maybe Harley Quinn took in Naruto when he was lost in her world and raised him as her own.
