Character Setting

Edit

Professor Samuel Oak (オーキド・ユキナリ博はか士せ, Ōkido Yukinari Hakase, lit. "Prof. Yukinari Ohkido") is a character appearing in Pokémon the Series. He is a Pokémon professor and researcher who was once a competitive Trainer and is generally considered to be the best in his field of research.

He also hosts post-episode lectures in the anime, five in total: Pokémon Kōza, Pokémon Daihyakka, Pokémon Daikentei, Pokémon Live Caster, and Pokémon Holo Caster. He is well-known for producing poetry about Pokémon, known as Pokémon senryuu (ポケモン川柳), although the art form was changed to generic rhyming poems in the English dub of the anime.

Professor Oak is a middle-aged man with peach skin, gray hair, and thick, bushy eyebrows. He wears a white lab coat, a light maroon polo shirt, a brown belt and beige pants, and matching brown loafers.

As a child, Professor Oak had short brown hair with a long fringe on each side and a full fringe in the front. He wore a white buttoned shirt, a brown belt, green pants, white shoes, and an olive green backpack.

Professor Oak lives up the road from Delia Ketchum and her son, and he and Delia often appear together as they are good friends. His known family are his grandson Gary, his cousin Samson and his great-grandfather grand Oak.

His often-forgetful attitude and other antics are also notorious. He also has a hobby of composing senryū, haiku-like poems about Pokémon or Pokémon-related themes.

In the novelizations written by Takeshi Shudō, Professor Oak comes from a prestigious family. He has two brothers, one of whom is the mayor of Pallet Town while the other is its postmaster. His grandfather was the first Trainer from Pallet Town to receive widespread recognition, while Samuel himself gained prominence after he published a research paper on Pokémon at the age of 20. It is also stated that he became a professor at Celadon University at the age of 25. According to Professor Elm, Professor Oak's studies and research mostly focus on how humans and Pokémon interact with each other.

Professor Oak has an issue with Ash's Muk. He often demands that Muk get off him when it always gets playful towards him and messes up his lab coat.

In "Alola, Kanto!", Professor Oak is very close towards his cousin, Samson Oak, when he visits with Professor Kukui, Ash and his Alolan friends at his lab in Pallet Town.
