Grudge is a Ghost-type move with no base power and 100% accuracy. When a Pokémon uses Grudge, if it subsequently faints due to a direct attack, all the PP (Power Points) of the move that caused it to faint is depleted. This move is typically used strategically to limit an opponent’s options by forcing them to lose all uses of a particularly powerful or troublesome attack. While Grudge itself does not cause damage, its utility in disrupting the opponent’s strategy makes it an interesting tactical choice in battles.
