Red's Articuno - Pokémon Origins

While investigating the Seafoam Islands for new Pokémon to collect and add to his Pokédex, Red came across Articuno. Impressed by their beauty, he caught them. He used his Rapidash to weaken them, before finally capturing them in an Ultra Ball. 

Red would later use Articuno in his fight against Mewtwo. Despite their best efforts and a powerful blizzard, the clone easily overpowered them.
