|“||That's not Groudon! It's evil! It's pure evil!||„|
|~ Butler lamenting the false Groudon he created.|
False Groudon resembled the real Groudon, but was much more demonic in appearance. It had lifeless yellow eyes, goopy teeth, and when it roared, a fiery, lava-like pattern appears on its underside. Its spikes and claws can transform into turquoise blue tentacles that it uses to consume other living beings.
According to Butler, it was overall a destructive incarnation of absolute and pure evil.
After Butler was exiled from Team Magma following the failure in creating a Groudon from a fossilized remnant, he used Jurachi's power from the Millennium Comet to bring the fossil back to life, believing he could impress Maxie enough to rejoin Team Magma. However, instead of creating Groudon itself, an evil monster resembling Groudon came to life. It 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 it met its end when Jirachi used Doom Desire to obliterate the clone and free the consumed Pokémon and people so that they will not die. Once it was eventually defeated by Jirachi, everything went back to normal.
- Some fans refer to this abomination as "Virus Groudon".
