I'm not sure if there is a specific fanfiction with that exact premise. There are countless fanfictions out there, and while some might come up with really wild and creative crossovers like this, it's not a common or well - known one that I'm immediately aware of.
In the comics, Nick Fury is indeed shown as black. This portrayal has been consistent over time and is an important aspect of the character's representation.
Yes. Nick Fury is black in the comics. This has been a consistent part of his character design and has been maintained throughout various comic storylines and adaptations.
Most likely not. Nick Fury's grave seems to have its own significance within the specific context of the story and not related to Pulp Fiction. Different elements and plotlines contribute to its meaning independently.
