If the user faints this turn, the PP of the move that fainted it drops to 0.

If the user is hit by a direct damage dealing attack and faints in the same turn that Grudge is used, the move that was used to make the user faint will have all of its remaining PP removed.
Grudge's effect lasts until the user uses another move.
Grudge will not take effect if the user fainted because of:

• Struggle
• End of turn damage effects such as:
  • weather effects (hail, sandstorm
  • status conditions (poison, burn)
  • delayed move damage (Leech Seed, Future Sight)

Grudge has no effect against Z-Moves.
Grudge will deplete all of the remaining PP of the base move that was used to perform a Max Move.

• From Gen 9 onwards this move can not be selected in battle.
