Defiant is one of the many abilities that are inheritable by Pokémon.
Function
When the possessor’s stats are subtractively modified by an opponent’s attack, its current Attack stat will upscale by two stages. Defiant will effectuate for each stat lowered; for example, if two of the possessor’s stats were to be lowered by the opponent, Defiant would activate in seamless succession, upscaling the possessor’s Attack by four stages total.
Self-inflicted stat-lowerings—a la usage of the Memento technique—will not trigger Defiant; only attacks deployed by the opponent will.
