|(げんしのちから Primeval Power)|
Ancient Power (Japanese: げんしのちから Primeval Power) is a move.
In Pokémon Platinum, one can purchase it in exchange for shards, and in Pokémon HeartGold and SoulSilver versions, one can purchase it in exchange for Battle Points. It can make Tangela evolve into Tangrowth, and Piloswine into Mamoswine and also Yanma into Yanmega.
It enables a Pokémon to use prehistoric power and has a one-in-five chance of raising all of the Pokémon's stats. The user picks up ancient rocks and throws them at the foe.
When the move is used, the Pokémon's body, shell, or otherwise usually glows white before becoming a see-through afterimage of the move user. The afterimage then spins quickly, turning into a silver ball in front of them that is then launched at the opposing Pokémon.
