A kid OC in a fanfiction could have a plot where they are immune to the zombie virus. Their group tries to keep this a secret from other, more dangerous groups who might want to use the kid for experiments. The kid then has to deal with the pressure of being the 'hope' for humanity while also just being a kid. They could also have a plot where they find an abandoned school and turn it into a safe haven for other kids. They have to defend it against raiders and walkers alike, and along the way, form strong bonds with the other kids.
Well, a great plot could involve a kid OC who discovers a hidden bunker filled with supplies but it's guarded by a group of unfriendly survivors. The kid has to use their wits to either befriend or outsmart them to get the supplies for their own group. Also, the kid OC could be an artist before the apocalypse and they use their art skills to create maps or symbols that only their group understands, which helps in navigation and communication. And there's always the idea of a kid OC who has a pre - existing medical condition and has to struggle to find the right medications while surviving the zombie hordes.
The OC could be in charge of training a group of survivors to become a more effective fighting force. They teach them military drills and how to use weapons properly. Along the way, there are internal conflicts within the group as some question the OC's strict methods.
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.
Perhaps an OC who is a young child with an uncanny ability to sense danger before it arrives. This could add an interesting dynamic to the group as they try to protect the child while also relying on the child's special ability to avoid walker herds and other threats.
An OC who was a streamer before the apocalypse. In the 'the walking dead' world, they try to keep their spirits up by pretending they are still streaming. They document their survival journey as if they are doing a special 'real - life zombie apocalypse' stream. They might even gain a following among other survivors who find their positive attitude inspiring.
One idea could be that the male OC is a former enemy who has a change of heart and ends up saving Maggie from a dangerous situation. Maybe he has some unique skills, like being an expert tracker, which helps them in their fight against the walkers.
A great plot for a 'Walking Dead OC fanfic' could be an OC who has a photographic memory. This OC could remember all the pre - apocalypse survival knowledge they read in books or saw on TV. They could recall details about building shelters, finding water sources, and making weapons. Their ability could make them a valuable asset to the group, but also a target as other groups might want to use their knowledge for their own survival. They would constantly have to balance between helping their group and protecting themselves from those who would take advantage of them.
One interesting storyline could be the oc kid's struggle to find their place in the post - apocalyptic world. They might have to learn survival skills quickly while also dealing with the emotional trauma of losing their family. Another could be their encounter with a group of survivors who initially don't trust them but eventually become like family.
One idea could be a vampire OC who was turned before the apocalypse and has been hiding their true nature. But in the chaos of the walking dead world, they find it harder to keep their secret. They could use their vampire abilities like enhanced strength and speed to fight off the walkers, while also trying to avoid being discovered by the human survivors.
A good plot could involve the male OC finding a cure for the walker virus (even if it's just a false lead at first). He becomes obsessed with it, and this drives his actions and relationships. Or perhaps he is wrongly accused of stealing from his group, and he has to prove his innocence while also dealing with the external threats of the apocalypse.
The OC could be a mysterious figure who has some sort of psychic ability. Paul Rovia is initially skeptical but as they face various threats in the Walking Dead world, her ability proves useful and they grow closer. For example, she can sense when walkers are approaching from a distance. This unique aspect of her character can drive the plot forward in the fanfiction.
