Undead mooks are the entire point of the Zombie Apocalypse. May be zombies, skeletons, or even mummies. An extreme form of Faceless Goons, in that while it's pretty hard to identify with someone with no face, it's basically impossible to sympathize with a corpse.note
May be spawned from Clown Car Graveyards, which act as Mook Makers. They may need to be killed in a certain way, or may even be completely unkillable, getting back up every time. If there's a Necromancer involved, defeating them may bring down this Keystone Army.
Sometimes the officer class will be made up of more strong-willed, sentient types of undead, such as vampires or wights. May be the official army of The Necrocracy.
If you really want to find these guys, look in the designated Big Boo's Haunt, or any other Unholy Ground. Animate Dead and Raising the Steaks might be ways to get troops for this. Compare/contrast Undead Laborers, who are used for constructive work rather than fighting, and Cavalry of the Dead, when the heroes' fallen allies rise to aid them as The Cavalry. Undead mooks are a staple of video games, Tabletop Games, and live-action alike. Being undead, the villain doesn't suffer Mook Depletion with these guys. Because they sometimes carry diseases that are fatal if left unchecked, they partially overlap with Instakill Mook. Compare Everything's Deader with Zombies.
