False Groudon is the main antagonist in the sixth Pokémon film, Jirachi: Wish Maker.
After Butler was kicked out of Team Magma after failing to create a Groudon from a fossilized remnant, in order to impress Maxie enough to rejoin, he used Jirachi's power from the Millennium Comet to bring the fossil back to life. However, instead of a regular Groudon coming to life, a monster resembling Groudon came to life, and destroyed plants and ate people and Pokémon by absorbing them into itself through its tentacles. It went completely berserk and consumed everything in its path, but met its end when Jirachi used Doom Desire to obliterate the clone and free the consumed Pokémon and people. Once it was defeated by Jirachi, everything went back to normal.
