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.
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.
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.
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.
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 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.
Perhaps the child OC is on a quest to find a missing family member in the post - apocalyptic world of The Walking Dead. They could encounter various groups along the way, some friendly and some not, which would create a lot of tension and character development.
One idea could be an OC who is a skilled medic. They could travel between different communities in the Kingdom, facing challenges like zombie attacks and distrust from some groups while trying to save lives. This OC could also have a backstory related to the pre - apocalypse medical field, which adds depth to their character.
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.
One idea could be to create an OC who is a healer in Ezekiel's community. They could have a backstory of being a medic before the apocalypse and use their skills to help the group. Maybe they have a special bond with Ezekiel as they both strive to keep the community alive.
First, give your OC a unique backstory. Maybe they were a military strategist before the apocalypse. Their skills from military training, like marksmanship and survival skills, can shape their actions in the Walking Dead world. For example, they could use their knowledge of tactics to lead a group to safety.
