MIGHTYENA gives obvious signals when it is preparing to attack. It starts to growl deeply and then flattens its body.This POKéMON will bite savagely with its sharply pointed fangs.
When this Pokémon enters battle, the opponent's Attack is lowered by one stage. In a double battle, both opponents are affected. This ability also takes effect when acquired during a battle, but will not take effect again if lost and reobtained without leaving battle. This ability has no effect on an opponent that has a substitute. Overworld: If the first Pokémon in the party has this ability, any random encounter with a Pokémon five or more levels lower than it has a 50% chance of being skipped.
