Perhaps the character is reborn as a member of a group that has a very different philosophy on survival compared to the groups we've seen in the show. They might believe in a more peaceful co - existence with the zombies, trying to understand and maybe even cure them. This would lead to a lot of internal conflict within the group as well as external conflict with other survivor groups who see the zombies as only a threat to be eliminated.
One idea could be the character being reborn as a zombie with some retained human consciousness. They could then try to find a way to reverse the zombie state while also facing the challenges of other zombies and survivors. Another could be reborn as a survivor in a different part of the world shown in The Walking Dead universe, like a hidden island where they have to figure out new survival strategies.
A plot idea might be that the reborn character has some special ability. For example, they can communicate with animals. In the world of the walking dead, this could be a huge advantage. They could use animals to scout for danger, find food sources, or even as a form of transportation. This would also bring a new dynamic to the interactions with other survivors, as some might be scared or jealous of this ability.
One idea could be that Harry Potter, through some magical mishap, ends up in the world of The Walking Dead. He uses his magic to protect a group of survivors from the walkers. Maybe he creates protective charms around their camp or uses the levitation spell to move heavy objects to block the walkers' paths.
One idea could be exploring a side character's backstory more deeply. For example, the character of Carver. What made him so cruel? You could create a fanfiction that shows his life before the apocalypse and how those experiences shaped him into the tyrant he became in the game. Another plot could be about a group of survivors finding an untouched, pre - apocalypse bunker full of supplies but also some dark secrets that test their morality. A third idea is to have a fanfiction where a character from the game gets bitten but instead of turning immediately, they seem to develop some sort of immunity and the group has to decide what to do with them.
One idea could be that Naruto and his friends are transported to the world of The Walking Dead. Naruto's ninja skills would be really useful in fighting the walkers. He could use his shadow clone jutsu to distract the walkers while the others look for supplies or a safe place to stay.
A great plot for 'Walking Dead Game' fanfiction could be a character who has the ability to communicate with walkers in a limited way. They use this ability to try and find a cure or at least a new way to co - exist. This would lead to a lot of moral dilemmas within the group as some might see it as a betrayal while others see it as a chance for survival. The story could explore how this character's actions affect the group dynamics and their relationships with other survivor communities.
Maybe Bella is a scientist before the apocalypse and she tries to find a cure using the resources available in the post - apocalyptic world. She could be constantly searching for a way to end the walker threat.
One idea could be that the Winchester brothers from Supernatural end up in the world of The Walking Dead. They could use their hunting skills to fight off the walkers. Maybe they'd discover that the zombies are somehow related to a demonic presence and try to find a way to stop it.
Well, a plot might involve Carl and Sophia finding a group of survivors who have a different way of living. They have to decide whether to stay with this new group or continue on their own. It could also be that Sophia gets injured and Carl has to find medicine for her, leading him into dangerous situations where he has to face not only walkers but also some not - so - friendly humans.
One idea could be an OC who has a unique skill like being able to communicate with animals in a limited way. This could help the group in various situations, like warning them of approaching herds. Another could be an OC who is a master of disguise and uses this to infiltrate enemy groups within the Walking Dead universe. For example, they could pretend to be a member of a hostile group to gather intel.
Well, a great plot for 'Walking Dead Do Over' fanfiction might be to explore what would happen if the group had found a more secure location right from the start. Say they stumbled upon an abandoned military base that was still stocked with supplies and weapons. This would change the entire dynamic as they wouldn't be constantly on the run for resources. Also, a plot where a character has premonitions in their dreams about future zombie attacks and they use this knowledge to prepare the group better. It could add a supernatural element to the otherwise gritty survival story.
One idea could be a little girl in the Walking Dead universe who discovers she has a unique ability to communicate with the walkers in a non - violent way. She uses this to lead a group of survivors to safety through areas filled with the undead. For example, she might be able to sense when a horde is about to move in a certain direction and warns her group.
