In some fanfictions, the Avengers could be stranded on the planet from Pitch Black. They'd have to rely on their survival skills and Riddick's knowledge of the terrain. Iron Man would be trying to figure out a way to get off the planet using his tech, while Captain America is leading the team in fending off any local threats.
I've read a fanfic called 'Avengers: Pitch Black Encounter'. In this one, the dark and gritty atmosphere of Pitch Black is brought into the Avengers' story. It shows how the Avengers deal with the dangerous and somewhat alien threats from Pitch Black. It's a really exciting read if you like action - packed crossovers.
One great Avenger crossover fanfiction is 'Avengers and the Justice League'. It's really exciting as it imagines what would happen if the Avengers from the Marvel universe met the powerful heroes of the DC Justice League. The story is filled with epic battles and interesting character interactions, like Iron Man and Batman sizing each other up, and Thor and Superman having a friendly competition of strength.
A good one has to blend the two universes well. For example, the unique and dangerous elements of Pitch Black, like the dark planets and the tough characters like Riddick, should be integrated in a way that makes sense in the Avengers' world. If it's just a random mash - up, it won't be good.
The Hulk could have an interesting reaction to the Pitch Black creatures. He might be both intrigued and enraged by their strange appearance and behavior. Meanwhile, Thor might see Riddick as a worthy warrior and try to engage him in a friendly combat to test his skills. This could lead to a mutual respect between them.
One possible plot could be that the characters from Harry Potter somehow end up on the desolate planet from Pitch Black. Harry and his friends could encounter the dangerous creatures of Pitch Black while trying to find a way back home. Hermione might use her magic to try and understand the strange environment, while Ron could be a bit more freaked out by the whole situation.
Pitch black fanfiction refers to fan - created fictional works that are often very dark in nature. It might involve complex and often disturbing themes like extreme psychological states, moral ambiguity, and sometimes elements of horror or intense drama. These types of fanfictions usually explore the darker sides of the original source material's characters or the fictional universe.
The fanfic 'Avengers meets the Fantastic Four' is also good. It plays on the similarities and differences between the two groups. The scientific genius of Reed Richards in the Fantastic Four is contrasted with Tony Stark's in the Avengers. And there are some hilarious exchanges between the more humorous characters like the Thing and Hulk. They also team up to face a threat that neither group could handle alone.
One idea could be to cross the Avengers with the characters from Harry Potter. Imagine Iron Man trying to figure out how to use a magic wand, or Thor comparing his hammer to a magic broomstick. Another idea is to crossover with the Star Wars universe. Captain America leading the Rebel Alliance against the Empire would be really cool.
Another great pairing could be Ron and Fry. Ron is a bit of a laid - back character who often follows Harry's lead, while Fry is a strong - willed woman. Fry could encourage Ron to be more independent and take charge. Ron could introduce Fry to the concept of magic, which she would find both amazing and a bit hard to believe at first. Their relationship could be a source of both comedy and growth in the fanfiction.
