Wonder Guard is a special ability in the Pokémon series that provides a unique defensive advantage. When a Pokémon has this ability, it can only be damaged by moves that are super effective against it. This means that most attacks will not affect the Pokémon at all, making it extremely difficult to defeat in battle. However, Wonder Guard is not without its limitations. It does not protect against status moves, such as Burn or Paralyze, and certain types of damage, like Weather effects or Entry Hazards, can still affect the Pokémon. This ability is most famously associated with the Pokémon Shedinja.
