"You and grandfather..."
"Imagine, the darkness in love with the light."
― Tenchi Masaki and Yuzuha (Tenchi Muyo: Daughter of Darkness)

The power to use the abilities of a Nephalem. Variation of Mythic Physiology and Hybrid Physiology. Combination of Angel Physiology and Demon Physiology. Not to be confused with Nephilim Physiology.

Also Called

  • Angel/Demon Hybrid
  • Angelic/Demonic Mimicry/Physiology
  • Diabolic/Angelic Angel/Demon Mimicry/Physiology
  • Nephalonic Mimicry/Physiology
  • Offspring of Angel and Demon


User with this ability either is or can transform into a Nephalem. These creatures have appeared in various forms of media, and have been described as the offspring of both an Angel and a Demon, but they can also be an Angel/Demon that possesses demonic/angelic powers. However, users of this power will have the potential to become more powerful than either side.

This is due to the fact that said spirit would be neutral and possess power from the forces of both Light and Darkness. These beings are based off of the Nephilim, the hybrid offspring of an Angel and a human, with the only difference being that both parents are immortal spirits. (Note: However, if the user who actually obtains this power is human, or alternatively a Nephalem mates with a Human, they will become/technically have a born child that would be just like the "Nephilim". In fact they would be an Angel/Demon/Human Hybrid.)

In terms of Moral alignment, Nephalems are neutral, but can go to the side of good, evil or anywhere in between. The same can also be said for the personality of said being. As for appearances, the wielders form can have unique features from both sides of their heritage such as small horns and/or a halo, some having eyeballs that are from an Angel and a Demon, sometimes having both a demonic and angelic wing on either side of their backs, or colored skin and a supernatural, glowing aura that displays their divine status.


  • Transcendent Form: As an ethereal being, Nephalems possess a body of divine nature that allows advanced physical abilities.
  • Divine-Demonic Force Manipulation: As offspring of an angel and a demon, Nephalems can control both holy and unholy forces and powers.
  • Ethereal Manipulation: They can generate and control Aether, a powerful, primordial element that was used to create the universe itself as well as Nether, the chthonian element, that flows through the realms of the Living and the Dead. This allows powers such as:
    • Nigh Omnipotence: As stated before, Nephalems are beings with the potential to become more powerful than Angels, and Demons. And because of the high level of control over both Aether and Netheral forces, the wielder can possess vast, but limited, amounts of power. This can allow powerful abilities such as:
      • Healing: Heal numerous amounts of people at a very high level with just a wave of the hand.
      • Elemental Manipulation: Control the elements around them to a degree that allows control of their environment.
      • Holy Fire Manipulation/Hell-Fire Manipulation: The power to manipulate the mystical flames of hell and the power to manipulate holy flames, which embodies the Purifying aspect of Fire.
      • Reality Warping: Warp reality at a level that depends on the wielders experience and willpower.
      • Resurrection: Revive deceased individuals no matter how long.
      • Superpower Manipulation: Conjure/Control supernatural energies that can empower chosen individuals.
      • Space-Time Manipulation: Utilize the forces of time and space to influence certain events.
      • Telekinesis: Transcendent level ability to manipulate structures at a subatomic level.
      • Twilight Manipulation: As mentioned before, Nephalems possess power from both Light and Darkness, allowing control over the element of Twilight.
        • Photo-Umbrakinesis: Gain a hybrid ability to control the elements of Light/Darkness to a wider degree.
        • Twilight Conjuration: Create anything based on the wielder's thoughts, and feelings to the level where you can conjure whole cities.
        • Twilight Dimensional Manipulation: Use the power to manipulate many dimensional energies to a high level and travel to planes of both Energy and Matter.
        • Twilight Energy Control: Manipulate that energy in a variety of powerful ways.



  • Despite being powerful than either said race alone, they would also possibly share both weaknesses from both Angels and Demons, especially whenever it comes to powers that are part of the demonic and angelic classifications.
  • The user may be driven into insanity with two of the demonic and angelic personalities interfering with each other, whether it would be permanent or temporary.
