Samson Oak: The Alolan Cousin Who Studies Regional Forms

He has Professor Oak's face and the vocabulary of a die-hard punster. Samson Oak is the Pokémon specialist based in Alola, a cousin of the Kanto researcher, and the archipelago has given him a research subject all his own: species that don't look the same there as they do anywhere else. The games make him a field researcher; the anime makes him the principal of a school.

The Alolan Branch of the Oak Family

The Oak name points to Kanto first and foremost. Samson Oak carries it all the way to Alola, where he works as a Pokémon specialist—a researcher's title, not the regional professor title that Professor Oak, his cousin, holds in Kanto.

The family resemblance is obvious at first glance. He has the features of his Kanto cousin, with two exceptions: he wears his hair noticeably longer, and he has a tanned complexion his cousin lacks. The likeness is strong enough that you notice it before you even learn they're related.

The family tree doesn't stop at this cousin. It also counts Blue among his relatives, as his first cousin twice removed, and Daisy Oak belongs to it too. So the character isn't a convenient namesake: he's part of a lineage that spans several regions and several generations of games.

Alolan Forms, His Field of Research

His research has a precise focus. In the archipelago, some species don't look the way you know them from elsewhere, and he's trying to understand what triggers these changes in form. That's the big question the region raises, and the game entrusts it to him rather than to anyone else.

You run into him in Sun and Moon as well as in their Ultra versions, always on the fieldwork side. His profile even gives him the title of Pokémon specialist, not regional professor: that nuance in wording says exactly what's expected of him.

His duties go beyond pure research. You meet him again at several spots across the archipelago, where he gives the player rare Poké Balls: the Friend Ball by the palm trees at Outer Cape, the Lure Ball deep inside the Geothermal Power Plant, the Moon Ball behind the Pokémon Center on Mount Hokulani, and the Love Ball at Malie Library once you've shown him an Alolan Persian. So the character isn't confined to a single exposition scene: he stays within reach once the story is under way.

The School Principal Who Talks in Puns

The anime introduces him in the very first episode of its twentieth season, and gives him a function rather than a cameo: he runs the Pokémon School. So the character enters the Alola saga through the front door, with a place and a role of his own.

His trademark comes down to a verbal tic. He imitates Pokémon and slips their names into ordinary words: in the French dub, "promesse" (promise) turns into "proMétang," and "connaissance" (acquaintance) into "Kraknoissance." The gag comes up often enough to be part of who he is, just as much as his job.

He also enters the Alola League, but his run there is short-lived: he's eliminated quickly. The character matters for what he holds—a school, a family, a research subject—far more than for his record as a Trainer.

A Sync Pair and a Trading Card

The mobile game added him on June 17, 2025, in his usual outfit, and pairs him with an Alolan Exeggutor: the logical partner for someone whose job is explaining regional forms. His description adds a personality detail—he's said to be a big fan of Mantine Surf.

The Trading Card Game had opened its doors to him much earlier, with the Team Up expansion, released in France on May 3, 2019. That's where he became a card for the first time, in the series based on the Sun and Moon games.

In short

Samson Oak holds an unusual place among the series' researchers: he bears a name the series made famous without holding the position that goes with it. No Pokédex to hand out, no starter to entrust—just an archipelago, a scientific question, a school to run and a stockpile of puns. Enough to make him a familiar face in Alola rather than just a nod to Kanto.
