Shieldon

Shield Pokémon ^#410

Although its fossils can be found in layers of primeval rock, nothing but its face has ever been discovered.

- Sturdy
  When this Pokémon is at full HP, any hit that would knock it out will instead leave it with 1 HP. Regardless of its current HP, it is also immune to the one-hit KO moves: fissure, guillotine, horn drill, and sheer cold. If this Pokémon is holding a focus sash, this ability takes precedence and the item will not be consumed.

- Soundproof
  This Pokémon is immune to moves flagged as being sound-based. heal bell is unaffected. uproar still prevents this Pokémon from sleeping. This Pokémon can still receive a Perish Song counter through baton pass, and will retain a Perish Song counter if it acquires this ability after Perish Song is used. howl, roar of time, sonic boom, and yawn are not flagged as sound-based.
