- Zombie Virus: Zombies are a type of Archenemy with biological origins. They come from the Acute Zombie Powder created by altering a virus found in the Caribbean (the original Zombie Powder virus) using a few different chemicals, including the drugs spoken of in the Haitian legends. Unlike regular zombies, Ayumi undergoes a special preservation treatment (thus the stitches covering her body) which prevents her from rotting as easily, allowing her to keep her superhuman athletic skills and intelligence.
- Immortality: Zombies are considered to be immortal. While damaged by blades or bullets as usual, they are capable of ignoring lethal wounds and continue moving as they are destroyed. However, zombies lack a vampire's regeneration, so they have to repair the damage suffered through sewing. While crushing their heart won’t kill them, destroying their brain kills them instantly.
- Infection: As the Acute name suggests, the virus carried by zombies is extremely virulent and has a nearly 100% chance of causing symptoms in both infected livestock and infected humans. Additionally, some plant species have been observed to undergo some cellular changes on exposure to the virus. A small bite or scratch is all a zombie needs to infect a healthy individual and create another zombie, which will happen within a few dozen seconds of being bitten. The virus allows infected to surpass their original body's natural upper limits. An individual zombie’s strength is reliant on the original being’s build and muscles, so their strength ranges from 1-10 times what it was in their original form. Unlike vampires, zombies have no hierarchy, so they won’t listen to anyone’s orders. Their intelligence and strength deteriorate as the rotting progresses. Particularly, the bodies of strong animals like rhinos or elephants who all are muscle break down much more quickly than human type zombies', so they don't last long.
