Arena Trap (Japanese: ありじごく Antlion) is an Ability introduced in Generation III. Three Pokémon can have this Ability, all of which are Ground types.
Effect
In battle
Arena Trap prevents all foes from fleeing or switching out as long as the user remains in battle.
Pokémon rendered immune to Ground-type attacks are immune to Arena Trap. This includes Flying-type Pokémon, Pokémon with Levitate, and Pokémon affected by Magnet Rise or Telekinesis. Likewise, if a Pokémon normally immune to Ground-type attacks is made vulnerable, they will be affected; if the Pokémon is under the effect of Gravity, Smack Down, a move that negates or replaces Levitate (such as Gastro Acid or Simple Beam), type change effects that remove Flying-type (such as Soak, Conversion, Camouflage, or Color Change), or a held Iron Ball, it will be unable to escape.
Using Baton Pass, U-turn or Volt Switch, or holding a Shed Shell will allow the Pokémon to switch out under all circumstances. Run Away will circumvent its effect to prevent fleeing, but not to prevent switching.
From Generation IV on, if two Pokémon with Arena Trap face one another, both may switch out or flee.
In Double Battles and Triple Battles, Arena Trap does not affect allies.
Outside of battle
From Pokémon Emerald onwards, if a Pokémon with Arena Trap is leading the party, then the wild Pokémon encounter rate is increased to 200%. It shares this trait with Illuminate.
