The Justified Ability is a rare Ability generally possessed only by Cobalion, Terrakion, Virizion and Keldeo as a result of their unique brain structure and its reaction towards negative energy. Pokémon in possession of this Ability are different from similar creatures because they are automatically born with a small nodule attached to their adrenal gland that normally should not exist. This strange nodule is in fact a highly-sensitive sack of tissue that reacts strongly in the presence of negative energy and induces an electric current when activated that causes the adrenal gland to release copious amounts of adrenaline into the possessor's system. In short, this nodule will automatically activate when the possessor is struck with a Dark-type attack (and will do so multiple times in the case of a Beat Up attack) and will raise the possessor's Attack stat with every single strike.
Tactical Advantages: The Justified Ability is not powerful enough to make much of a difference in most battles, but when fighting against Dark-types, this Ability can at least help keep the physical offenses of the possessor high and make it difficult for the opposition to resist the increased damage brought on by its effects.
Tactical Disadvantages: None.
