Sheninja (Pokémon)

Sheninja is a Ghost and Bug-type Pokémon known for its unique ability to become invisible and immune to most attacks. It is a small, ninja-like creature that can vanish instantly, making it difficult for opponents to hit. Sheninja has a sensitive shell called the "Shell Bell," which allows it to survive attacks that would normally cause fainting, but it can only endure one hit before fainting itself. Its notable ability, "Wonder Guard," grants it protection from most types of moves, making it highly elusive in battles. Despite its fragile appearance, Sheninja's defense hinges on its ability to avoid damage altogether.
