In a 'batman kills fanfic', it's a deviation from the norm. Fanfics often play with established characters in new ways. Here, Batman killing might be used to create a shock factor or to tell a story that challenges the status quo. It could be set in an alternate universe where the rules are different. It might also explore the psychological impact on Batman himself, as killing would go against everything he stands for in the regular DC Comics world. It's a creative exploration by fans who want to see what would happen if Batman took a more lethal approach.
I'm not entirely sure specifically what a 'naruto kills fanfic' is. It could be a fan - made story where Naruto kills someone in a non - canonical or creative scenario. It might be a very specific plot within the Naruto fanfiction community that focuses on Naruto taking a life, perhaps in a dark or alternate universe story.
A fanfic where Batman kills Joker could be very complex. For instance, the Joker may have planned his own death in a way that would make Batman cross the line, in order to prove that everyone can be corrupted. Batman's killing of Joker could then send shockwaves through the criminal underworld and among the other heroes. Some may see it as a necessary evil, while others may view Batman as having become a murderer, leading to a great divide in the DC universe of the fanfic.
A 'batman prank fanfic' could be about fans creating fictional stories where Batman is involved in some sort of prank. Maybe it's the Joker trying to prank Batman in a really elaborate way that the fans have come up with, or Batman himself pulling a prank on his enemies as a way to outwit them in a more humorous rather than violent way.
I'm not sure there are any extremely popular 'batman kills fanfic' in the mainstream sense. Since it goes against Batman's core character trait of not killing, it might not have as wide an appeal as more canon - compliant fanfics. However, in some niche corners of the fanfic community, there could be some that have a following among those who like exploring darker and more alternative versions of the character.
The Joker's death at Batman's hands could also have an impact on the other villains. Some might see it as a warning and become more cautious, while others might see it as an opportunity to fill the power vacuum left by the Joker. Harley Quinn, for example, could either be driven to seek revenge on Batman or be forced to reevaluate her own life of crime without the Joker's influence.
A 'batman medical kink fanfic' might involve scenarios where Batman is in a medical setting within the realm of fan fiction.

However, without reading it, it's difficult to say precisely.
Batman age play fanfic is basically fan fiction centered around Batman where age is a significant factor. Some of these fanfics may focus on Bruce Wayne's childhood and how his early experiences shaped him into becoming Batman. Others could be about an aged Batman nearing the end of his career and how he deals with new threats while also reflecting on his long - standing battles. It allows fans to add their own interpretations and twists to the Batman story by manipulating the age element.
It would be a very dark and twisted take on the Batman story. The whole dynamic between Batman and Robin would be completely changed. Robin would likely be filled with rage and a desire for revenge against Batman. It would also shatter the image of Batman as a hero in the traditional sense.
It could imply that in some Batman - related fan - made fictional works, there are scenarios where Batman kills, which might be a departure from the traditional non - killing Batman in the official canon.
There may or may not be such a 'batman kills robins parents fanfic'. Fanfics cover a wide range of ideas, some of which are quite out - there. However, this idea seems rather extreme for the Batman universe. Batman is usually a protector, and killing Robin's parents would be a huge departure from his normal values. If it exists, it's likely a very niche and perhaps controversial piece of fan - created work.
