The user of Fly will fly up high on the first turn, disappearing from view and becoming invulnerable to most attacks. On the second turn, Fly deals damage.

While in the air, the Pokémon can only be hit by the moves Gust, Twister, Thunder, Sky Uppercut and Smack Down, with Gust and Twister dealing twice normal damage. Moves from No Guard Pokémon, or any move following an identify move can also hit for regular power.

If the user is holding a Power Herb, Fly executes in one turn.

When a Pokémon is holding Flyinium Z and uses its Z-Power, Fly turns into Supersonic Skystrike and has base power 175.

Fly allows you to fly instantly to any PokéCenter you have already visited during the course of the game (or certain other prominent locations). It can only be used with the appropriate Gym Badge.
