is a fictional species of Pokémon from Nintendo's and Game Freak's Pokémon media franchise. The result of an extraterrestrial virus's exposure to a laser beam, Deoxys frequently appears around auroras. It is recognized as a Mythical Pokémon of the third generation. It exists in four forms: Attack, Defense, Speed, and Normal, which differ by base stat values, effort value yield, and appearance. Originally, there was no Speed Form; this was added after the movie.
Deoxys first appeared in the 2004 video games Ruby and Sapphire, accessible via a Nintendo promotional event. It played a major role in the film Pokémon: Destiny Deoxys later that year. It has since appeared in several video games and the Pokémon anime series. The Pokémon has also been featured in official merchandise and a collaboration with NASA, and has received positive remarks from critics.
