Description
Professor Samuel Oak is a Pokemon expert from the Kanto region. While in the Kyoto region, Professor Oak gives the player their first Pokemon. Oak will also give the player a Machamp to use as a ride Pokemon, if they visit his lab in Battle City. Professor Oak concentrates on relationships between humans and Pokemon in his research. He is an idol to many trainers, including the Johto region Professor, Professor Elm.

Role

He plays a more major role after the player has defeated at least 7 of the 8 Kyoto region gyms, defeating him being the final part of a story quest. After being defeated by the player, he will give the player a Jade Orb, the item required to open the Dragonid Tower, in Wyvern Village.

Relatives
While he is at home in the Kanto region, Professor Oak takes care of his grandchildren: Blue and Daisy, whose parents died in a car accident.
