Well, Mary is also a main character. She is very intelligent and uses her wits to find food and supplies. She often comes up with creative solutions to the problems they face in the post - apocalyptic world. Another important character is Tom. He is a bit of a loner at first but gradually becomes part of the group. He has a special ability to sense danger before it arrives, which is really useful in their fight for survival.
The tone can be different too. The original 'The Walking Dead' is mostly about survival and the dark side of humanity during a zombie apocalypse. But 'the walking dead lemon fanfiction' might add elements of humor or different kinds of relationships that are not as prominent in the original. For example, there could be more light - hearted moments between characters that contrast with the overall grimness of the show.
The most interesting part could be the new characters it introduces. These characters often bring fresh perspectives and storylines into the 'Walking Dead' universe.
The story of Negan is also a top one. His brutal rule over the Saviors and his complex relationship with other groups, especially his interactions with Rick's group, made him a very interesting character in the series. He brought a new level of danger and unpredictability to the post - apocalyptic world of 'The Walking Dead'.
