The user will even develop a power to counteract the powers of another, such as gaining a Psychic Shield to protect oneself from a soon to be telepathic intrusion. 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. User may be able to read different languages after moments of looking them up or be able to withstand a constant bombardment of radiation.

As for limitations, the ability only activates for imminent or very probable threats to the user and the powers gained are likely to be lost once the threat is gone. Maybe the user may or may not be able to control adaptations. And also, some adaptations may be in conjunction with weaknesses.

Yay or nay?
