Professor Oak

Professor Samuel Oak, shortly Professor Oak, is the supporting character of Pocket Monsters.

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 License or not. Once again, he debuted in while he was running 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 was stated during his conversation with his grandson Blake Oak, Blake's parents left him with Professor Oak a while ago before they went on a safari across the world. Therefore he had been taking care of his grandson, Blake, since they were away. Despite Blake claimed that his parents just abandoned him, Professor Oak insisted on his thought of that his parents only wanted him to be qualified to be safe during their safari. Once Blake was done with his journey in Kanto, he could join them.

At the same time, Professor Oak gave 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 revealed in, Professor Oak occasionally went to explore Kanto for specific reasons such as looking for medicines or discovering new stuffs he was interested in. One of those explores long ago, while they were in Viridian Forest, Professor Oak and Fennel encountered an Eevee who was abandoned but Eevee 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 was one of the rare people whom Eevee actually trusted in.

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

As it was stated in, Professor Oak built the years ago while he was in need of a battlefield to host the Summer Camp Competitions, and let his companies, strong Trainers all around the world, have a platform to battle each other. The platform was used for the current summer camp students for the first time in that chapter.

Part Red & Green


Professor Oak reappeared in, visiting Redwald and the others after Redwald's first gym battle. Along with him, he also brought Fennel and Aubrey. In the chapter, he introduced one of his former students, Aubrey, who also happened to be one of the former Kanto League Champions. He stated that he was the responsible one of regularizing the manditory battlefields in the backyard of each Pokécenter in Kanto region. After he introduced Aubrey to the others, he asked Redwald, Greta, and Blake to stay for one more day for the conference he had the next day, and requested them to participate.

Part Red & Blue
Professor Oak made his first appearence in this part in. Along with his chef assistant Fennel, they spotted the weirdness within the air temperature in Pallet Town and Kanto region as a whole. While researching this issue and trying to be involved to the meetings with the Weather Institution in Kanto, they simultaneously encountered a stranger girl in Pallet Jungle blacked out, named. Professor Oak let her stay in the laboratory until she feels better, but she was more mysterious than he thought. As the girl did not speak with anyone in the beginning, Professor Oak wanted to give her enough time and space to pull herself together and made sure that she was safe.
