Aero is one of Red's Pokémon. Aero is a male Aerodactyl.
Aero was given to Red in the form of the Old Amber by Giovanni. The Old Amber is recognized by Blaine, who sends Red to Blaine's secret laboratory to revive it. After revival, Aero battles Moltres and forces Team Rocket to return it and flee.
Aero accompanies Red to Cerulean Cave, but is caught up in the twister, forcing Red to return him. Red later sends him out to fly into the center of the twister, sending Pika in with the Master Ball to capture Mewtwo.
In the FRLG Arc, Red, Blue and Green go to Five Island to battle against the newly-reformed Team Rocket, who had awakened the DNA Pokémon, Deoxys. In Red's battle against it, Aero is badly injured when Deoxys' sharp tentacles pierced Aero's wings, causing it to temporarily lose the ability to fly.
