Fear the Walking Dead season 8 has brought back the metal head walkers from the original The Walking Dead franchise, potentially solving a mystery that has been unanswered for seven years. The Sanctuary, where the characters now reside, has a large number of these walkers, suggesting they may have been the original creators. This provides an opportunity for Fear the Walking Dead to explain the origins of the metal head walkers, while also highlighting their unique and dangerous abilities. This development adds nostalgia and potential possibilities to the current season.
