Shadow Tag prevents all foes from fleeing or switching out as long as the user remains in battle.
Using Baton Pass, U-turn or Volt Switch, or holding a Shed Shell will allow the Pokémon to switch out under all circumstances. Teleport, Run Away, and the Smoke Ball will circumvent its effect to prevent fleeing, but not to prevent switching.
From Generation IV on, if two Pokémon with Shadow Tag face one another, both may switch out or flee.
In Double Battles and Triple Battles, Shadow Tag does not affect allies.
