Gravity is a Psychic-type move that causes intense gravity for five turns. During this time, Flying-type Pokémon lose their immunity to Ground-type moves and Toxic Spikes. Moves that require the user to be airborne, including Bounce, Splash, High Jump Kick, Jump Kick, Magnet Rise, and Fly, will fail. The intense gravity will also decrease the evasion of all Pokémon by two stages while present.
