Description
Jacq is an instructor who serves as the biology teacher at Naranja Academy in the Paldea region. He is a tall man with light tan skin, platinum gray eyes, and layered purplish-gray hair. His distinctive appearance includes hexagonal glasses, a white lab coat worn over a violet and magenta striped shirt, purple jogging pants, and white slippers with dark magenta straps. Beyond his teaching duties, he is known for his research on ecologically similar Pokémon in collaboration with the World Pokémon Ecological Society. He also developed the Pokédex application for the Rotom Phone.

In terms of personality, Jacq is highly knowledgeable and well-versed in his field, but he has an airheaded quality and can sometimes become so absorbed in his own research that he loses track of his surroundings. He possesses a friendly and cheerful demeanor, and he is consistently eager to assist students while encouraging them in their pursuits.

Within Pokémon Horizons: The Series, Jacq makes his first appearance at Naranja Academy when he meets the young protagonists Liko, Roy, and Dot. During this encounter, he requests that, as they participate in the Terastal Training course, the group also take photographs and compose reports about any wild Pokémon they encounter during their travels. He is later mentioned by Director Clavell, who notes that Jacq sees significant potential in the three young Trainers. Jacq subsequently appears alongside Clavell to welcome students back to the academy, promising to read their reports with care, and joins them in watching the Elite Four Tag Battle. He has also made appearances in other animated productions set in the Pokémon world.

Regarding key relationships, Jacq interacts directly with Liko, Roy, and Dot as their instructor at Naranja Academy. He works alongside Director Clavell in supervising student activities and assessments. His collaborative research efforts connect him with the World Pokémon Ecological Society.

Information about substantial character development for Jacq within the series is limited, but his role primarily revolves around his function as a supportive educator who provides guidance and encouragement to the main characters as they undertake their training.
