When a player downloads Pokémon Bank anytime between December 27, 2013, and September 30, 2014, they will receive the Mythical Time Travel Pokémon Celebi! This special Celebi comes with the move Hold Back, a restrained attack that cannot be learned through normal gameplay, which always leaves the target with at least 1 HP. This allows players to weaken a target with certainty and is very useful in capturing Pokémon. This particular Celebi also knows the moves Recover, Heal Bell, and Safeguard.
