The ability to self-amputate/sever appendages. Variation of Anatomical Liberation.

Also Called

  • Defensive Amputation
  • Reptilian Regeneration
  • Self-Severing
  • Willful Amputation


The user can self-amputate/sever their appendages (limb, finger, leg, tail, etc.), usually as a self-defense mechanism in order to escape an opponent or predator's grasp. The missing body parts regeneration can vary from a few minutes, to a few days, possibly even longer depending on the circumstances, after self-severing.



  • Body parts do not grow back automatically.
  • Will not help the user offensively.
  • May feel pain while using autotomy.
  • May not be able to regenerate anything other than limbs/tails (if the head were removed, the user may very well die.)
  • Limb may grow back differently than before.
