Jacq is a character from the Paldea based Pokémon games (Scarlet or Violet).
Jacq serves as both the player (Florian or Juliana)'s main homeroom teacher as well as the Biology teacher at Naranja or Uva Academies, depending on the games. Jacq also created the Pokédex application for the Rotom Phone, and sometimes gets a little excited when it comes to breakthroughs in research. This gets him in trouble with Director Clavell.
