Enfermeira Joy is a collective identity representing a large family of Pokémon nurses who operate Pokémon Centers across various regions. The Joy family shares identical physical appearances and voices, with Joy serving as their common surname. Minor distinctions between them sometimes appear in details like the color of the cross on their nursing caps or slight variations in eyelash length. In the Sinnoh region, Enfermeira Joy performs her established role of healing and caring for sick or injured Pokémon, typically assisted by Chansey or its evolved form, Blissey. These Pokémon are trained in medical care and know healing techniques, making them ideal partners. She remains consistently kind and dedicated to Pokémon welfare, though she can display sternness when confronting those who harm Pokémon or during times of extreme busyness. A significant familial background is revealed in Sinnoh, where this Enfermeira Joy is married and has two daughters, Marnie and Paige. Both daughters aspire to follow their mother's career path and become Nurse Joys themselves. This particular Joy utilizes three Drifloon owned by her daughter Marnie for delivery purposes, such as transporting lunch to her husband who works at the Valley Windworks power plant. When Team Rocket's attempt to steal an Ampharos causes damage to the plant and a regional blackout, Enfermeira Joy travels to investigate. During this crisis, her younger daughter Paige becomes involved in a dangerous situation that requires intervention from the legendary Pokémon Suicune, with whom both daughters share a secret friendship. Beyond standard nursing, Enfermeira Joy and her relatives occasionally serve as judges for Pokémon Contests and Grand Festivals. They have also acted as Pokémon League inspectors who evaluate Gym Leader applicants for proper procedures and qualifications. In some instances, Joys have held positions such as Director of Expedition Teams, demonstrating the family's diverse professional contributions. She maintains a consistent appearance across regions with minor variations. In Sinnoh, she wears a Mexican-pink colored dress with a white nurse apron and flat Mary Jane shoes, matching the uniform worn in Kanto, Johto, and Hoenn regions. Her expertise extends beyond standard medical care to include specialized knowledge of Pokémon habitats and physiology, as demonstrated when one Joy was utilized for this knowledge by Mewtwo. This professional competence is matched by a compassionate nature that typically manifests as patience and understanding, though exceptions have occurred in highly stressful environments such as the polluted Gringy City, where a Joy initially showed less enthusiasm before recommitting to proper care standards.
