Maybe in this fanfic, the world of Gotham and the world of Death Note collide. The Shinigami start to appear in Gotham, which causes mass panic. Batman starts to investigate these strange supernatural beings. He discovers the Death Note and realizes its power. He then has to figure out how to stop the Shinigami from causing chaos in his city and also prevent any humans from using the Death Note to kill others, as it would lead to a complete breakdown of the already fragile justice system in Gotham.
Batman would likely be very suspicious of Light Yagami. Light sees himself as a kind of 'god' when he has the Death Note, but Batman, who is all about justice in a more traditional sense, would not tolerate Light's actions. He would probably try to stop Light from using the Death Note. As for L, they might initially be at odds as they both are brilliant detectives, but they could end up working together to stop the misuse of the Death Note.
One interesting crossover could be Batman getting his hands on the Death Note. He would likely be very conflicted about using it. On one hand, he could potentially rid Gotham of its worst criminals without having to physically fight them all. But his strong moral code would probably prevent him from using it, as it goes against his belief in justice through the legal system. Another aspect could be L from Death Note trying to figure out Batman's identity, using his detective skills which are somewhat similar to Batman's own.
No. 'Death Note' is a complex and dark story mainly focused on themes like justice, power, and morality. 'Lemon' fanfics, which usually imply sexual content, are not in line with the original work's tone and are inappropriate as they distort the intended meaning of the story and its characters.
The 'gay Death Note fanfic' is different as it often focuses on relationships and emotions in a way the original doesn't. The original is more about the cat - and - mouse game of justice and power. In the fanfic, there could be a lot of focus on how two male characters interact on an emotional and physical level. It might also change the pacing of the story. While the original had a fast - paced plot with new twists and turns related to the Death Note, the fanfic could slow down to explore the development of a relationship, with detailed descriptions of their first meetings, first kisses, and so on.
A 'death note lemon fanfic' is likely a fan - created fictional story related to 'Death Note' that contains 'lemon' elements. 'Lemon' in fanfic terms usually refers to sexual or romantic content. However, this goes against the original tone and nature of 'Death Note' which is mainly a psychological thriller. It might involve the characters from 'Death Note' in romantic or inappropriate situations not shown in the original work.
One idea could be a character from Naruto finding the Death Note. For example, Naruto himself stumbles upon it. He might initially be confused by it, but as he realizes its power, he has to grapple with the moral implications. Should he use it to eliminate dangerous enemies like Orochimaru? This would create an interesting internal conflict within Naruto as he is known for his belief in second chances and redemption.
Ryuk would probably just be amused. He is a Shinigami who has seen a lot in his existence. Fanfiction is just another strange human creation to him. He might chuckle at some of the more outlandish ideas in the fanfictions, like a character having superpowers beyond the Death Note.
