|Debut:||Yaiba: Ninja Gaiden Z|
Zombies are the animated corpses of human beings that appear as the main enemies in Yaiba: Ninja Gaiden Z.
- The Infected/Stiffs: The most basic variation of the Zombie, these undead monsters slowly shamble toward their target and attack by punching and biting. Not particularly hard to deal with alone, they can be overwhelming in groups.
- Infected Torso: A regular Stiff cut in half, these torsos can climb on their victims to drain their health and slow them down.
- Grunt: Zombified army personnel. Function similarly to Stiffs only tougher.
- Grenadier: Zombified army personnel loaded with explosives, they attempt to take their victims with them by exploding.
- The Brawler/Punchdrunk: A Zombified ex-boxer and MMA fighter, Vseslav Degtyarev.
