Also Called

  • Impossible Teaching/Training


The user can train, instruct, or otherwise teach to others skills/abilities that cannot be naturally taught. For example, superpowers unrestricted to combat and condition, or skills unable to be masterfully performed by someone like them due to whatever reason.

The teacher may not have to have the abilities to teach them, but knowledge and understanding of the ability must be present in order for the ability to be taught "correctly".




  • Any power taught incorrectly may become disastrous to use.
  • Failure to control a powerful ability may result in injuries, or even death.
  • Teaching others will take time.
  • Because of the Plateau effect, the student may reach the peak of their physical and/or mental limits and never improve beyond that.
  • Uniqueness cannot be taught.
