Prevents other Pokémon's moves or Abilities from lowering this Pokémon's stats.
This Pokémon cannot have its stats lowered by other Pokémon. It can still lower its own stats via moves like Hammer Arm.
This ability does not prevent any stat losses other than stat modifiers, such as the Speed cut from paralysis. This Pokémon can still be passed negative stat modifiers through Guard Swap, Heart Swap, Power Swap or Speed Swap.
