The power to be mutated through fusionism. Combination of Fusionism and Mutant Physiology. Variation of Mutated Physiology.

Also Called

  • Fusion/Fusionism Mutant/Mutated Physiology


The user can undergo genetic mutation through unstable fusionism, allowing them to become monstrous mutants of terrifying power through instability, which can be caused in a variety of ways beforehand.

As usual, this is the most unstable power to possess, allowing the user to go through genetic instability which results in mutations into a full-fledged monstrosity. However, aside from that, the user will still be granted more powers and abilities as they mutate gradually.




  • It is the most unstable power to have by far, and the user would may not be able to unfuse in this state.
  • The user will become much more emotional (for example, being prone to being berserk and full of rage) to the point of losing rationality.
