A fanfic could also center around Adrian Brody's character being abducted by the Predators and then having to endure their cruel tests and games. But instead of breaking, he manages to learn from them, their technology and fighting styles, and eventually turns the tables on them when he is finally let loose on their ship.
One idea could be a story where Adrian Brody's character is a lone survivor in a post - Predator - attack world. He uses his wits and skills to outsmart the Predators that are still lurking. Maybe he teams up with other survivors who initially don't trust him but soon realize his value in the fight against the alien hunters.
First, do your research on both Adrian Brody's acting style and the Predator franchise. Understand the kind of characters he usually plays and the nature of the Predators. Then, come up with a unique plot. It could be something that combines the elements of his past roles with the Predator lore. For example, if he often plays complex, troubled characters, make his character in the fanfic have some inner turmoil related to the Predator encounter.
One good Adrien Brody Predator fanfic could be one that focuses on his character's survival skills. For example, a fanfic might explore how his character uses his wits and physical abilities to outmaneuver the Predator in different terrains. Maybe he creates elaborate traps using the natural resources around him, like in a jungle setting. Another aspect could be his psychological battle with the Predator. He has to stay calm and think several steps ahead to survive.
How about a plot where they are both lost in a magical forest? They have to rely on each other to find their way out. Along the way, they discover secrets about each other that they never knew. Or they could be in a modern - day Romeo and Juliet situation where their families are in business competition, but they fall in love secretly. There are so many possibilities when it comes to writing fanfic about Adam Brody and Rachel Bilson.
A plot could involve a group of humans who are caught in the middle of a war between Predators and Aliens. They form an alliance with a rogue Predator who has his own reasons for wanting to stop the fighting. Maybe there's a powerful Alien queen that the Predators are desperate to kill, and the humans get dragged into that mission.
In some Predator fanfics, Adrien Brody's character might be portrayed as more fearless than in the movie. He could be taking more risks and being more aggressive towards the Predator. For example, instead of waiting for the Predator to make a move, he initiates attacks.
One idea could be a mystery where Natalie goes missing and Monk has to use his unique detective skills to find her. He has to overcome his own OCD tendencies while dealing with the chaos of the situation.
One idea could be an OC who is a scientist accidentally stumbles upon a Predator's hunting ground. The OC has to use their wits and scientific knowledge to survive and even form an unlikely alliance with the Predator. Maybe the OC discovers a way to communicate with the Predator through some sort of energy signal, which intrigues the Predator enough to not kill them right away.
One idea could be that they struggle with how to balance their dreams and the new baby. For example, Rachel might be worried about her Broadway career being put on hold. Another could be that they face judgment from their friends in Glee club. Maybe some think they are too young or not ready. And a third plot idea could be that they discover some family secrets during the pregnancy that add more drama to the story.
A really interesting plot could be set in an alternate universe where the wizarding world has different social hierarchies. Hermione, being a Muggle - born, has to face more challenges, and Adrian Pucey, from a pure - blood family, has his own set of expectations. Their relationship develops as they both try to break free from the constraints of this new world order. For example, they might team up to fight against a discriminatory law that targets Muggle - borns. This would involve a lot of character development and exploration of the wizarding world's politics.
There are fanfics where the Predators come to Earth not for hunting but for a different purpose like seeking an ancient artifact. In these stories, they interact with humans in unexpected ways. For example, a group of scientists discovers the Predators' true intentions and decides to help them in their quest, leading to a unique alliance between the two species.
