Zombies are reanimated, mindless, decaying corpses with a hunger for human brains. They are the main antagonists of Plants vs. Zombies Odyssey, as the objective of the game is to prevent them from eating the player's brains. Zombies, like their defensive counterparts the plants, are varied in strength as well as speed, and command unique aspects which must be countered appropriately.
A grand total of 35 zombies appear in the game so far.
