"The Walking Dead: Daryl Dixon" introduces a new character called Genet, who may hold the key to uncovering the origins of the zombie virus. The gray-haired scientist, known as "The Doctor," that Genet has employed, could be responsible for the outbreak. He conducts experiments to mutate zombies into more dangerous killers, suggesting he played a role in the virus's release. The Doctor's ongoing experiments and conflicted behavior hint at the possibility of him creating a cure. The series finale of "The Walking Dead: World Beyond" further hints at the international origins of the virus and the Primrose team's involvement. Genet's connection to the virus makes her an important villain in the franchise.
