Eagun (Japanese: ローガンLogan) is the grandfather of Rui and husband of Beluh. Eagun is a very old man with much white hair, a long white beard, and flowing purple robes.
The elder of Agate Village, he considers it his personal duty to protect all of the other senior citizens in Agate, as well as their Pokémon. In his youth, Eagun was one of the greatest Pokémon Trainers in Orre, if not the world. However, once he started to age, he retired and now lives in the base of a large living tree in Agate Village. Despite his age, Eagun is still in excellent shape, being able to easily outrun two healthy people a fraction of his age.
Eagun still keeps the first Pokémon he ever received with him, a Level 50 Pikachu. He also has a collection of other Pikachu, Pichu and Raichu trained to varying levels. Despite his experience and power, Eagun was too old to prevent members of Cipher from invading the Relic Cave in an attempt to destroy Celebi's Relic Stone. A Cipher Peon was able to knock out Eagun's Pikachu using the power of a Shadow Pokémon, a Hitmontop, but Wes and Rui stepped in to stop him.
The old Trainer is highly enthusiastic about Pokémon legends and myths, two of his favorites being Ho-Oh and Celebi. He's also known for having seen a Ho-Oh at least twice in his lifetime. Eagun has trouble with gadgets, especially new technology. He's only just learned to type in his old age. This in particular caused him and others some needless complications. Namely, when trying to inform Wes that he was to give him a Master Ball, he accidentally sent an incomplete message to Wes, causing him and Rui to think he was in serious trouble.
