"You can bleed us to the brink of death, crush every bone in our bodies, it only makes us more powerful!"
― Vegeta to Cui, Dragon Ball Z

The ability to develop adaptations, powers, or skills in response to immediate threats. Not to be confused with Evolution.

Also Called

  • Instant Adaptation
  • Instant Evolution
  • Nemesis
  • Reactive Evolution
  • Spontaneous Adaptation
  • Self-Modification
  • Zenkai (Dragon Ball series)


The users can either instantly develop powers or abilities to deal with threats or their bodies dynamically learn from experience. Depending on the user's control of the power or genetic structure, the reactive effects can be permanent or temporary.

For example, after a certain situation, the user's skin may become tougher. They may display increased IQ after a difficult test or fortified emotions after a personal argument. The user may be able to read different languages after moments of looking them up or be able to withstand a constant bombardment of radiation. Some users may develop Enhanced Durability after being shot, or grow Dermal Armor, or gain the opposite power of their opponent.

In some instances, a magical object may express similar powers.






  • Adaptations may only be temporary.
  • Cannot function against users of Adaptation Immunity.
  • Can be defeated or even die before the adaptation even takes place.
  • Certain hidden threats may not be reacted to.
  • May be vulnerable to Downgrading.
  • New adaptations may grow naturally or be produced as a monstrosity.
  • Learning some adaptations may negate other adaptations (e.g. learning to breathe water may prevent breathing air).
  • Some adaptations may be in conjunction with weaknesses, even downright detrimental outside the object of adaptation.
  • Some reactions may have a delayed response.
  • Some threats may be beyond the extent of what the user can adapt to.
  • The extent and speed of adaptations may vary between users.
  • The users may or may not be able to control these adaptations.
  • Usually dependent upon a direct threat to the person, resulting in responsive action.
