In the anime
Lunatone was first introduced in "Crazy as a Lunatone", where it emerged from a meteorite that crashed in the Hoenn region, however the Pokémon Mystery Club had an interest in capturing it. Lunatone used its psychic ability to delay the P.M.C. while it escapes to a nearby town, it then used Hypnosis on Nurse Joy in order to take shelter at the Pokémon Center. Ash, May (anime), Brock, and Max arrived at the town, and, suspecting that something was wrong, they sneaked into the Pokémon Center and encountered Team Rocket. They soon face Lunatone, however Lunatone completely lost all of its energy after battling Team Rocket. Ash and the others decided to help out Lunatone by taking it to Camerupt Point in order to regain its energy from the moonlight. They soon face Team Rocket again however Team Rocket was defeated by the P.M.C. that planned to catch Lunatone, it regains its energy and defeated the P.M.C. and heads to space.
