Catherine Maurel, a French volleyball player, joins the Dragon Ladies as a central player who occasionally substitutes as an outside hitter, wearing jersey number 4. Her fiercely ambitious and competitive demeanor initially creates friction with teammates like Glin Wong and Gina. On the court, she executes signature techniques: the "Batida da Cobra" (Cobra Strike) and "Esmagamento do Trampolim" (Trampoline Smash). Despite early conflicts, she reveals unwavering loyalty to her teammates and becomes an integral asset to the team. Catherine evolves from confrontational individualism to a committed focus on collective success, actively sharing techniques—such as teaching Maria Rodriguez the Cobra Strike—while learning from others. Though her background includes prior volleyball experience, specifics of her early life or pre-Dragon Ladies career remain unelaborated. Her driving motivation centers on propelling the team toward qualification for the 2008 Beijing Olympics.
