U-Turn is a Bug type move introduced in Generation IV. It is TM89, given by Professor Bamb'o after registering 125 different species of Pokémon in the PokéDex.
U-Turn allows the user to switch out to its Poké Ball immediately after inflicting damage to the foe. If there is only one Pokémon left in the user's team or if the user is a wild Pokémon, no secondary effect will apply. It shares this effect with Volt Switch
