The power to be an empowered undead. Variation to Undead Physiology and Empowered Subject Physiology. Opposite to Mutated Undead Physiology. If the user loses their physical body, they gain Superior Ghost Physiology.

Also Called

  • Advanced Undead Physiology
  • Empowered Undead Physiology
  • Metaundead/Neoundead/Superundead Physiology
  • Micromutated Undead Physiology (Rational Only)


The user of this ability is an undead subject of superior power. Much like the rest of the empowered races, metaundead are much stronger than regular undead all thanks to having superpowers, and they tend to be more difficult to dispatch, at least depending on what powers they possess, whether they almost dwarf the power of a undead lord or not. They can also be much more intelligent than their regular predecessors, at least depending on their power sets.

Superundead can also be divided into two categories:


Metaundead of this category gain their powers via evolution, genetic engineering, or exposure to radiation or biohazardous substances, like mutagens, or any other methods that involves genetic experimentation in that regard.
In one way or another, certain superundead that are of this classification might have minor physical changes, like having retractable claws or spikes, and among others. In fact, these kinds of empowered undead will be able to possess powers without their physiology being altered.


Non-scientific superundead gain their powers by being given them, enchantment, blessing, granted wishes, etc., without bio-engineering based alternatives. Unlike scientific-based superundead this category of metaundead wouldn't have to be able to suffer mutations and instability of their DNA, which can be caused in certain specific ways. Unlike rational based metaundead they are more likely to maintain their respective physiology because they don't share the same genetic unpredictably that rational-based superundead are more likely to have.

Powers that users may possess, but are not limited to:

    • Supernatural Hunters are more than capable of handling the undead.
    • May be difficult, or impossible to revert back to a normal form.
    • May need to consume living flesh, blood, life energy, etc. in order to survive.
