Here's an idea. In the fanfiction, there could be a character who has a special ability like being able to sense where the zombies are coming from. This person then becomes the leader of a group of survivors. Another plot could be that there are different types of zombies with different abilities. For example, some can climb walls and others can run really fast. The survivors have to learn how to deal with each type as they try to find a safe haven. And also, a story where the zombies are attracted to a certain type of sound or smell that the survivors have to figure out and avoid.
One idea could be a group of survivors who are all musicians. They use their music to communicate with other groups across the apocalyptic landscape and also to keep their spirits up. Another could be a story where the zombies start to regain some of their humanity and the survivors have to decide whether to trust them or not. Maybe a story about a scientist in the group who is trying to find a cure using only the limited resources they have.
One idea could be a gamer who uses their in - game survival skills to lead a group in the real - world zombie apocalypse. For example, they know how to scavenge for resources just like in the games they play.
One idea could be that the Forbidden Forest becomes the breeding ground for the zombies. The magical creatures there are either zombified or in a fight for survival. Hogwarts students, led by Harry Potter, have to use both magic and their wits to fend off the undead hordes while also trying to find a cure within the castle's ancient secrets.
One idea could be that the kids of South Park form their own survival squad. Cartman might try to hoard all the food, leading to comical in - squad conflicts. Another could be that the zombies are actually the result of a failed experiment by Professor Chaos, and the boys have to find a way to reverse it. Maybe Stan and Kyle have different ideas on how to deal with the zombie threat, with Stan being more practical and Kyle more idealistic.
One idea could be that the vampires in Twilight are immune to the zombie virus at first. But then they find out that the zombies are evolving and starting to pose a threat to them too. So they have to team up with the werewolves to fight the zombies. This would create an interesting dynamic as they have their own feuds but are forced to cooperate.
One interesting zombie apocalypse story is 'The Walking Dead'. It follows a group of survivors in a world overrun by zombies. It shows their struggles, the moral dilemmas they face, and how they try to build a new society. Another great one is 'World War Z'. It has a global perspective, with different accounts of the zombie outbreak from various parts of the world.
One idea could be Naruto using his shadow clones to distract the zombies while he and his team find a safe place. Maybe he discovers a new jutsu that can control the zombies instead of just defeating them.
One idea could be that the gods have lost their powers due to some ancient curse, and it's up to Percy and his friends to find a way to restore them before the apocalypse fully hits. Maybe they have to journey to the very origin of the gods' power.
One idea could be exploring the backstories of the minor mutants more. For example, how did they discover their powers before the events of Apocalypse. Another could be a time - travel fanfic where a mutant goes back in time to stop Apocalypse from ever rising to power. Maybe also a fanfic about the mutants trying to adapt to a post - Apocalypse world and rebuilding society in a more mutant - friendly way.
In a fanfiction, perhaps there's an apocalypse scenario where Superman is infected with some kind of kryptonite - based virus that makes him go berserk. Batman has to find a cure while also keeping Superman from causing too much damage. At the same time, they are dealing with the general chaos of the apocalypse, like gangs taking over the city and other villains trying to take advantage of the situation.
Well, you could have a story where a high - school is the setting for the start of the zombie apocalypse. A group of students and teachers have to work together to barricade the school and survive. There could be a love story intertwined within this, like two students who find each other during the chaos. Also, an idea could be that the zombies are actually the result of a failed military experiment. A journalist tries to expose the truth while fighting off the zombies and dodging the military who wants to keep it all a secret.
