Power to use a soul to morph one's form and spiritual attributes. Combination of Amalgamation, Soul Absorption and Transformation.

Also Called

  • Soul Metamorphosis/Transformation
  • Spiritual Avatar/Fusion
  • Idle Transfiguration (JUJUTSU KAISEN)


The user can morph their form via the souls of elemental spirits of nature, spirits of the long-departed, demons, angels, and deities. They can combine different souls to form new transformations for themselves or use them to create super forms or hyper forms of said synchronized spirit. The user can forcefully combine with a foreign spirit or deity if their soul is strong enough to make the souls of the spirits submit to them or defeat the spirits in battle. Some bodily transformations include all the basic forms listed under Mythic Physiology.




  • Insanity is a possible side effect from staying in the form for too long.
  • The user can become berserk after overuse.
  • Battle-lust can take control of one's body and mind.
  • Imprisoned/Fused souls may rebel against the user's dominant soul.
  • The user is required to make a recombinant soul submit to their own soul to morph into them.
  • The user may have to form a contract to take on the form of higher beings (i.e. gods).
