What could be the possible plot in a 'Naruto kills Batman' fanfiction?

One possible plot could be that Naruto is somehow corrupted. Maybe he's been influenced by a powerful dark force or a powerful enemy has tricked him into believing that everyone is a threat to the world he wants to protect. So, he decides to take extreme measures and kill everyone to 'create peace' in his warped sense.

There could be a 'catwoman kills batman fanfiction'. A possible plot could be that Catwoman is in a situation where she has to choose between saving the city and Batman. She might think that sacrificing Batman is the only way to stop a greater evil from destroying Gotham. For example, if there's a doomsday device that can only be deactivated by Batman's death and she decides to go through with it.

For such a plot to be possible in the fanfiction, it could involve some major changes in the Naruto world. The Akatsuki could have some new secret weapons or techniques. Also, Naruto might be in a situation where he is not able to access his full power, like being poisoned or something. And perhaps the Akatsuki are more united and desperate than ever to achieve their goals, leading them to take out Naruto who is a major obstacle for them.

Well, perhaps in this fanfiction, Naruto is somehow transported to the Batman universe and is neglected by the local heroes at first. He then has to prove himself by using his ninja skills in Gotham's dark alleys, like using his shadow clones to confuse the bad guys and his speed to catch the elusive criminals.

One possible plot could be that Naruto is forced into a situation where he has no choice but to kill Haku in self - defense. Maybe Haku is under some kind of mind control and attacks Naruto relentlessly.

It could start with a rift between them that becomes unbridgeable. Sasuke might side with a group that Naruto is sworn to oppose. Their ideological differences grow to such an extent that they end up in a final battle. Naruto, with a heavy heart, kills Sasuke perhaps because Sasuke refuses to back down and his actions are endangering too many lives. This would be a tragic departure from the original story where their relationship was centered around mutual understanding and redemption.

One possible plot could be that Naruto is somehow transported to the Batman's universe. Maybe a villain with reality - warping powers is involved. And the 'lemon' aspect could be a code name for a new, experimental weapon in Gotham that Naruto and Batman have to work together to stop from falling into the wrong hands. They would combine Naruto's ninja skills with Batman's detective and combat abilities.

It could also be due to mind control. A powerful villain might have controlled Wonder Woman's mind and made her turn against Batman. In this scenario, Wonder Woman would act against her own will and kill Batman, creating a tragic situation in the fanfiction.

One possible plotline could be that Darkseid is about to destroy Gotham or Earth in a way that Batman has no other option but to kill him. Maybe all of Batman's usual gadgets and allies are useless, and he has to use a kryptonite - like weapon (if it could affect Darkseid) to take him down.

In such a fanfiction, perhaps Kawaki is driven by some extreme ideology. Maybe he believes Naruto's way of peace is a weakness and decides to take him out to change the ninja world in a more radical way.
