Shiny Absol is a rarely found and highly unique type of the Pokémon Absol obtained in random battles and through Pokémon breeding. It has a unique color and a special effect when brought out for battle.
Shiny Pokémon are just very rare colors of standard Pokémon. They have a base appearance rate of 1 in 8,192 in random battles but a slightly better chance to appear during Pokémon breeding. By breeding an American Pokémon with a Pokémon from another country, the chance increases to 1 in 2,048. Trainers can obtain a Pokémon from overseas through trading. It should be noted, however, that shiny Pokémon are not better than their normal counterparts; they just have a different look.
