General Abilities

• Limitless Stamina: Undead beings, moreso with ghosts, across fiction normally don't show signs of fatigue or the need to rest.

• Resistance to Death Manipulation: Due to already being dead. It would be like using Resurrection on something that is already alive.

• Resistance to Mind Manipulation: Some forms of undead can be considered "mindless". Making attacks that attack the mind pointless along with many other abilities that go after the mind like Madness Manipulation, Emotional Manipulation and Willpower Manipulation.

Types

1: Physical. Characters that are physical forms of undead. I.E. zombies, mummies, living skeletons, etc.

Notable Applications:

• Immortality (Type 2): Normally already undead beings of this nature can survive attacks that would kill a regular living being. Like being shot in the head, the destruction of internal organs and being chopped in half.

• Corruption (Type 2): In some popular works of fiction undead beings, particularly zombies, can turn others into living creatures through varying means/ Whether that would be through biting, scratching or some other physical means. This is also typically paired up with some sort of disease.

• Enhanced Bite and/or Natural Weaponry: Zombies in particular normally use their teeth and nails to cut through flesh and turn others into the undead.

Examples: Captain Long Ben One-Leg (Goosebumps), Zombies (Yakuza), Nathan Grantham (Creepshow), Jason Voorhees (Friday the 13th)

Type 2: Non-Physical. Characters that are non-physical forms of undead. I.E. spirits, ghosts and some forms of wendigo.

Notable Applications:

• Intangibility: Phasing through physical matter is a popular trope for entities like ghosts.

• Invisibility: Throughout fiction ghosts can't be seen by the living or are completely invisible.

• Longevity or Immortality (Type 1): Ghosts either don't age entirely or age slower then the average person.

• Non-Physical Interaction: Throughout multiple fictional verses, ghosts can interact with each other.

• Possession: It is a popular trope with things like wendigos and spirits to possess inanimate objects or other beings as a host.
