| Arena Trap
Arena Trap (Japanese: ありじごく Antlion) is an Ability introduced in Generation III. All Pokémon that have this Ability are Ground types.
Arena Trap prevents all grounded foes from fleeing (including Teleport) or switching out as long as the user remains in battle.
Using Baton Pass, U-turn, Volt Switch, or Parting Shot will still cause the Pokémon to switch out. Holding a Shed Shell allows the Pokémon to switch out, but not flee or Teleport. Having the Ability Run Away or holding a Smoke Ball allows the Pokémon to flee or Teleport, but not switch.
If a wild Pokémon has Arena Trap and the player's Pokémon faints, if the player attempts to flee instead of sending out another Pokémon, they are unaffected by Arena Trap.
Arena Trap does not affect allies.
Ghost-type Pokémon are now immune to Arena Trap.
Outside of battle
From Pokémon Emerald onwards, if a Pokémon with Arena Trap is in the first place in the party (even if fainted), the wild Pokémon encounter rate increases by 100%. It shares this trait with Illuminate and Swarm.
