Professor Rowan

Professor Rowan is the Pokémon Professor of the Sinnoh region in the anime (Pokémon the Series: Diamond and Pearl). He is an older man (around 60) with fair skin, blue eyes, spiky white hair, sideburns, and a mustache. He typically wears a gray jacket over a white shirt with a light blue vest, gray tie, dark teal pants, and gray shoes (occasionally adding a white lab coat).

In personality, he comes across as strict, serious, and stoic—often stern or intimidating at first glance, with a no-nonsense demeanor that contrasts with the more cheerful professors like Oak. However, he's actually kind, patient, fair, and deeply caring about Pokémon and young trainers. He takes his responsibilities very seriously and is a renowned researcher, particularly focused on Pokémon and their evolution (though the anime emphasizes his role in guiding new trainers more than deep research scenes).

He runs his lab in Sandgem Town, where he provides starter Pokémon (Turtwig, Chimchar, or Piplup) to beginners like Dawn (whom he gives her Piplup in her debut episode). He's good friends with Professor Oak and appears periodically to offer advice, monitor events (like Team Galactic threats), or host activities like the Pokémon Summer Academy. Overall, he's portrayed as a wise, authoritative mentor figure who values the bond between trainers and Pokémon.
