I assume you are not referring to characters that can transpose the damage back to the dealer. If that is the case  I think it is a form of Desperation Attack, a form of Comeback Mechanic,Critical Status Buff, or Situational Damage Attack. It is something of a mix of tanking and characters resolve. Metal bat in OPM is purported to have this ability. Lucario also has this ability in super smash bro's brawl, Hulk sort of because he gets angrier.
