A Fan with a Plan (Japanese: 強敵！？ママさんコーディネーター登場！ Formidable Enemy!? Mother Coordinator Enters!) is the 37th episode of Pokémon: Advanced Challenge.
The gang stops in Rubello Town and Ash would check the Pokémon Center. Max spots a poster, advertising the Pokémon Contest in Town. May is sure to stay until tomorrow night, but Brock sees a mark - R1. When they arrive, they ask Nurse Joy what R1 means. Joy says that one must have 1 ribbon already to enter. Luckily for May, she has 2 already. Joy says it are the Grand Festival rules, so May asks what that is - Drew is not surprised that she does not know. Drew is entering the Contest as well, taunting May. Suddenly, some women arrive to Drew - they are his fans.
One of them asks for an autograph, so Drew replies he "does not do autographs", amazing the fans. A woman asks May is she is Norman's daughter, so she confirms, so the fans come to her. The woman asks May is she's going to enter the Contest as well, so she also confirms. The other women cheer for the one with a ribbon on her neck. They mention MFP - Mothers for Pokémon - they are a group of wives, mothers and love Pokémon. They all agree to get May in a party. One of the women asks Ash if she saw him before and check her list, but with no matches. Team Rocket appears in the Town as well, so Jessie want stop enter the Contest. When explained to her what R1 means, she gets frustrated. The receptionist tells her she can't enter when she does not have any ribbons, depressing her.
The women give compliments to May, having earned 2 ribbons. One of the women asks her what Pokémon should she use, but May does not know yet. May asks the Coordinator which Pokémon she will use, so the women agree if she shows hers, May might have her choosing easier. At the Pokémon Center, the women leave, reminding the Coordinator of the list - the list of what to do. Brock knows that housework is a hard job, while Ash compliments him for being successful in those kind of jobs. Anyway, the woman shows Flareon and Lairon - the Pokémon she'll use in the Contest. She'll use both Pokémon - rules are that the Pokémon must be different in primary and secondary battles. May is left to think to decide which Pokémon should she use...
The gang is wandering the town, while Brock shows Savannah some good tomatoes. May is still unsure what Pokémon should she use. Brock is about to take a turnip, but a girl takes the vegetable. It is Savannah's daughter, Sandra, who helps her do grocery shopping. Savannah introduces Sandra to the gang. Savannah tells May and Max are Norman's children, but Sandra tells Savannah can get carried away, especially in MFP. Ash gives his Pikachu to Sandra for holding and Sandra decides she'll become a trainer. Per Sandra's advice, Savannah invites the gang for dinner, to which they agree to.
May trains her Pokémon, but all of them fail. However, May remembers the women supporting her, so she gains confidence to win. May hears Drew training his Masquerain. Drew invites May to come closer. They spot one another's new Pokémon, and while May orders Bulbasuar to meet Drew, it ignores her. May decides to enter the Contest with her Bulbasaur. The next day, Brock, Ash and Max ask May to come to do grocery shopping, but she says she needs to practice with Bulbasaur. The others are terrified because May has recently got Bulbasaur. May spots Savannah, being very upset when she's going to perform. Savannah asks May if she's going to practice with her. She spots Bulbasuar, mentioning that her 1st Pokémon was a Bulbasaur, but it is at her parents' home.
Meanwhile, the rest is shopping while Ash's Pikachu comes to Sandra. Anyway, May will battle with Savannah. Lairon attacks with Metal Claw, but Bulbasuar tries to cancel with Vine Whip, but with little difference. Flareon attacks with Flamethrower, but the attack is negated by Razor Leaf. However, Team Rocket steals the ribbons so that Jessie will enter the Contest. Bulbasaur attacks with Razor Leaf, but the attack is deflected by Dustox's Whirlwind. Flareon uses Flamethrower, but unexpected, Jessie's Wobbuffet reflects the attack. Dustox uses Poison Sting, but Pikachu's Thunderbolt negates it. Brock sends Lombre and Mudkip to use Water Gun, however Wobbuffet reflects the attacks.
Sandra goes after Team Rocket. Dustox uses Psi Beam on her, but is rescued when pulled with Vine Whip. Flareon uses Flamethrower on the balloon, knocking Team Rocket down. When James and Meowth tell Jessie that nobody is going to believe that it are her ribbons, Jessie gives them back. Sandra whispers Savannah some advice and orders Lairon to use Water Pump, blasting them off. Savannah is sure to have a tough competition with Drew and May...
The infamous Trainer's Choice error: Viewers are asked which among Suicune, Sableye, and Arbok evolves into Seviper, with the "correct" answer being Arbok, even though Arbok is the only evolution of Ekans, and none of the other three Pokémon have any Evolutionary Line whatsoever (notwithstanding Mega Sableye, introduced a decade later).
