"Guardian Angel" Walker
Age
Late 20's to Early 30's
While traveling to the Prison, Andrea and Milton run into this walker. After subduing the zombie, Andrea hacked off its arms and then curb-stomped it on its own arms to break its jaw, so as to not bite. As Andrea begins to wrangle the zombie, she refers to it as her "Guardian Angel"; the zombie's body odor covers her scent so other zombies don't attack her. She then proceeds off to the Prison and where she later discards the zombie, the walkers outside the prison no longer appear at the prison in Season 4, meaning that the "Guardian Angel" walker and the rest of the walkers have been put down.
