From Bulbapedia, the community-driven Pokémon encyclopedia.
Grandpa (Japanese: じーちゃん Grandpa) is a creepy mad scientist in the romantic manga series Magical Pokémon Journey. He is a genius at making all sorts of things, such as love potions, magic mirrors, and a magical suit that will protect its wearer from harm. He sent Hazel out to catch Pokémon for him so that he could impress girls, but she has not yet caught any.
Grandpa is married to Ginger and is the grandfather of Coconut. He is apparently the president of Pog, Inc, but does not want to return because running the company isn't fun.
Most of his inventions don't work.
