Professor Oak

Professor Oak is a supporting character. He lives in Pallet Town where he has his laboratory to make his researches.

The Beginning


Professor Oak regularly holds a summer camp in his laboratory with 16 chosen students across Kanto to decide whether they should earn a Pokémon Trainer Licence. He debuts in when he runs another one in his laboratory. He has an assistant team in his laboratory which is led by Fennel Walker. His Clefable is his loyal henchman in the laboratory.

As it is stated during his conversation with his grandson Blake Oak, Blake's parents have left him with Professor Oak a while ago before they went on a safari across the world. Therefore, he has been taking care of his grandson Blake since they are away. Despite Blake claims that his parents just abandoned him, Professor Oak insists that his parents only want him to be qualified for a safe journey during their safari. Once Blake is done with his journey in Kanto, he could join them.

At the same time, Professor Oak gives his students their starter Pokémon and a Pokédex for each, expecting them all to pass through the exams during this ten weeks.

As Fennel Walker reveals in, Professor Oak occasionally goes to explore Kanto for specific reasons such as looking for medicine or discovering new stuff he is interested in. One of those explores long ago, when they were in Viridian Forest, Professor Oak and Fennel have encountered an abandoned but he was not ready to face it. Professor Oak and Fennel tried their best to take care of him, eventually ending up bringing him to the laboratory. Ever since Eevee accepted the truth that he was actually abandoned, Professor Oak is one of the rare people whom Eevee actually trusts in.

Also as Fennel reveals, Professor Oak and his Clefable have a special bond between each other which would let them understand each other telepathically. This is a myth that some people would believe. According to this myth, this would only occur when the Pokémon and its Trainer have a special and unvisible bond between each other.
