Nurse Joy (Japanese: ジョーイJoy) (original name Pokémon Center Lady in the card game) is the name of multiple nurses that work in Pokémon Centers throughout the various locations in the regions in the games and anime. A Nurse Joy can completely restore any Pokémon back to perfect health. She has appeared in Pokémon games since the beginning of Generation I.
Much like in the games, most of the Nurse Joys have brink pink hair and fair skin. Others could have a lighter shade of hair color, or brighter or darker skin. The Kanto, Johto, Hoenn, and Sinnoh Nurse Joys wear a Mexican-pink colored dress with a white nurse apron, and low-heel Mary Jane shoes. In Unova, Nurse Joys have different hairstyle with the hair being tied in rounder rings, a plain pink dress with a shorter apron, white pantyhose, and pink shoes instead of white. Kalos Nurse Joys wear a pink and white dress with a white collar, and the same pantyhose and shoes as the ones in Unova. Nurse Joys in the Orange Archipelago wore more summer-themed clothing, including a pink, short-sleeved shirt and a teal apron with a tropical flower design on it, though one Nurse Joy travels around the islands in her kayak, wearing a blue-and-yellow wet suit and having darker skin due to suntan. Nurse Joys could be distinguished from other Nurse Joys by the color of their cross, or badge.
One exception is in Pokemon The First Movie, where the Nurse Joy of Old Shore Wharf had been kidnapped and brainwashed by Mewtwo to serve him as his maid with false memories that made her believe she lived on New Island her whole life and served him the whole time while he used her knowledge of Pokemon physiology to his advantage. She's only seen wearing the trademark uniform of Nurse Joys of Kanto, Johto, Hoenn, and Sinnoh in a missing person poster. While on New Island, she wore a red dress and hat with a white cloth that hid most of her head from view except for her face until Mewtwo released her from his mind control. When Brock caught her as she fainted, the hat fell off, revealing the rest of her head. She remained wearing the dress until the end of the movie, when Mewtwo erased her memories of the events on New Island and sent her back to Old Shore Wharf, where she appeared to take Trainers to the Pokémon Center for shelter from the storm, wearing a hoodie with her Red Cross on it instead of the usual uniform.
A Nurse Joy is placed inside every Pokémon center in every town, in every game. She is always behind the Pokémon center, waiting for a new customer. When you approach her and talk to her, she will say, "Welcome to the Pokémon Center, where we will heal your Pokémon back to full health. Would you like me to take your Pokémon?" If you click no, she will say, "We hope to see you again," but if you click yes, she will say, "Okay, I'll take your Pokémon for a few seconds." She will then take each of your Poké Balls and place them on a tray, where they will light up numerous times before Nurse Joy takes them and hands them back to you. She will then say, "Your Pokémon are now healed. We hope to see you again." On your birthday, she will ask you if it is your birthday and she will wish you a happy birthday. She will also say a little bit of Pokérus if your Pokémon has it or was cured from it.
This phrase has gained a lot of jokes to it, due to the fact that Nurse Joy says, "We hope to see you again," making it sound like she wants your Pokémon to get injured again so that the player would have to go back to the Pokémon Center.
Nurse Joy will always heal the player character's Pokémon, except in the Battle Mansion.
In the anime, the reason that Nurse Joys are all over the place is because they're all related. Not only that, Joy is their family name and not their actual first names (Along with them looking identical, they are also all voiced by the same person, making them sound identical too.).
Although they all appear identical, Brock is able to tell them apart by little details. This is noted when he can tell the difference between the eyelash length of two different Nurse Joys. Brock has a main crush on Nurse Joy, although he's always interrupted by his Croagunk, Max, or Misty. Nurse Joy is actually one of the few girls in the anime that does not reject Brock. She will just look at him, confused, before he is pulled off by one of his friends.
Once, during DP, Brock was put under a sleeping spell and dreamed that Nurse Joy and Officer Jenny fell in love with him. They then clung to him for the rest of the episode. At the end of the episode, dozens of Nurse Joys and Officer Jennys rushed over to Brock to "love" him, but Brock was then woken up by Croagunk's Poison Jab.
Nurse Joys are known as caring women who always help a Pokémon in need. However, although they may seem nice, they can become quite tough when they have their hands full, or when they confront a person who hurts Pokémon (aka, Team Rocket). Other than that, all Nurse Joys seem to be in a good mood all the time.
Each Nurse Joy can be told apart by the color of the plus on their nursing cap, just as Officer Jenny's can be told apart by the badges on their police officer caps.
