Also Called

  • All-Heart
  • Heart Mimicry/Manifestation
  • Cardiovascular Mimicry/Manifestation/Physiology
  • The Heart
  • The Living Cardiovascular System
  • The Living Heart


User is an entity completely comprised of a heart, multiple hearts or recurring aspects of the cardiovascular system. This could count as a literal meaning, their physiology looking and behaving just like a regular heart, or this could be symbolic, their physical form a manifestation of their heart.




  • Being that the heart is an incredibly sensitive organ, the user may be very vulnerable in this state.
  • Should the heart entity and the person it spawned from coexist, they may have differing morale and could clash against one another.
