Professor Cozmo
Professor Cozmo (Japanese: ?, German: Kosmo, Italian:Professor Cosmi, Spanish: Cozmo) is an meteoriticist who lives in Fallarbor Town in Hoenn.
In the Games
Professor Cozmo leaves either with Team Aqua or Team Magma for the Meteor Falls, thinking that they were going to help him excavate meteors. However, the offending Team steals the meteor. The playable character then gets it back for the Professor in exchange for TM27, Return.
In the Anime
In Fight for the Meteorite, Professor Cozmo meets Ash Ketchum on Mt. Chimney. The situation from there is similar to in the games.
In the Pokémon Special Manga
Professor Cozmo believed Team Aqua to be noble heroes, so he assisted them with the meteor and their device on Mt. Chimney.
He's apparently good friends with Roxanne, and was once her teacher.
In the TCG
In the EX Deoxys expansion of the TCG, he appears on a card called Professor Cozmo's Discovery.
