A yellow-orange ball forms in front of Lugia's mouth. Lugia's body then starts to glow blue and it fires multiple beams of yellow-orange from its mouth which eventually converge into a single destructive beam, surrounded by a vortex of wind, which is fired at the opponent. Alternatively, Lugia will open its mouth and gather blue energy inside it. It then fires a massive beam of energy from its mouth at the opponent.
In Generation II, the anime, and the second Pokémon movie, Aeroblast is portrayed as one or more beams of destructive energy. However, starting from Generation III and the Super Smash Bros. series, Aeroblast is depicted as a concentrated, hurricane-like vortex stream.
Aeroblast is the only Flying-type move introduced in Generation II.
