Caution: spoilers ahead for The Walking Dead: Dead City episode 5.While The Walking Dead: Dead City's multi-limbed sewer zombie is certainly one of the most outlandish creatures seen in the AMC franchise so far, the undead monster isn't necessarily one of The Walking Dead's elusive variants. The Walking Dead: Dead City episode 5 concludes with Lauren Cohan's Maggie Rhee and Mahina Napoleon's Ginny taking a tense walk through the zombie-infested sewers of Manhattan, and their journey ends with the surprise appearance of a creature unlike any seen previously. Boasting a cacophony of flailing arms and numerous protruding heads, this sewer-dweller would look more at home in Alien than the zombie apocalypse.
