When Misty, Jenny and Joy/Mask along with May who was under Misty/Masks control appeared at the camp site where Ash, Pikachu, Brock and Dawn was sleeping until Dawn woke up hearing sounds in the bushes as she took a flashlight out of her bag and walked deeper into the woods unaware that the masked girls were dressed in Team Rocket uniforms to disguise themselves as Jenny/Mask rolled a chloroform filled Pokéball between Dawn's feet as she looked down as the ball sprung open as Dawn felt dizzy and fainted as Joy and Misty/Mask carried her to a secret location where they took a large white cloth and gagged her.
When Dawn was out cold from the chloroform, Joy and Jenny/Mask stripped Dawn out of her normal Pokémon trainers outfit and silently got her into a Mismagius costume as they wrapped Dawn's around her body and fastened them in place as they pulled a pair of purple stockings and purple heeled shoes as she started to come around as she was gagged so all she could do was mumble.
Just then Dawn didn't recognize the women holding her as they wore Pokémon shaped masks as Officer Jenny wore a Growlithe mask and Nurse Joy a Blissy mask to conceal their true forms.
Just then Dawn was able to wriggle her way out of the gag as she said,
"Let me go or you'll be sorry," as she looked at the two masked women who was holding her.
Just then Misty/Mask wearing a goldeen mask to conceal her true form, just laughed and said,
"Now Dawn you will become one of us and nobody can save you from the masked sisters," she replied as she took the Mismagius hat with attached hood and walked closer and closer to Dawn as she looked on in horror.
Before Misty/Mask wearing a goldeen mask over her face got close to Dawn she clicked her fingers as May in slave costume walked behind her and placed a leather gag harness over Dawn's mouth and nose and tied the straps around to the back of Dawn's head and fastened it tight before taking the top strap and pulled it straight over the top of Dawn's head and fastened it tight so Dawn couldn't speak as she watched the masked woman walk closer and closer to her. Just then Misty/Mask wearing her Goldeen mask took the Mismagius hat and attached mask and pulled it down over Dawn's head and said,
"Now you belong to the masked women," as she laughed as she pulled the hat and attached mask down over Dawn's head and face until it would go any further as Misty/Mask tucked the mask down into the start of the costume top.
After Dawn opened her eyes, all she could see was purple as she looked through the eye holes as Misty, Nurse Joy and Officer Jenny all took off their plastic Pokémon shaped masks and revealed their true forms as Misty/Mask took out a small chain and pocket watch and started to swing it back and forth as she started saying,
"Dawn you are now my obedient slave and you will help me be the Pokémon Mistress of the world," she said as Dawn became hypnotized and nodded her head as they went to devise a plan to get Ash on his own.
Early the next morning, Ash, Pikachu and Brock woke up and saw Dawn was missing as they went looking in the forest for Dawn. A couple of hours later Ash with Pikachu and Brock returned to camp and said,
"Where could she have gone, Brock?" he asked.
"I don't know Ash but her backpack and Pokéballs are still here," replied Brock as they packed all their stuff up along with Dawn's and continued looking for her has they reached the next city.
When they made it to the next major city, Ash, Brock and Pikachu was about to walk into the police station until they saw a notice on the door saying,
"We're sorry but for certain reasons we have had to close for the missing Officer in charge of this city please visit the Pokémon Center for more details." As Ash, Brock and Pikachu entered the Pokémon center with their bags and Dawn's stuff and Pokémon.
Just then Zoë, Dawn's friend and contest rival entered and said,
"Hey Ash, Hey Brock, Hey Pikachu, Where's Dawn?"
"We don't know but we think that she was kidnapped during the night," explained Brock as Nurse Joy seeming back to her old self walked through the door and said,
"Good morning everyone, what can I do for you?"
Just then Brock instantly went bonkers as he floated over to Nurse Joy and held her hand started saying romantic stuff as Nurse Joy though mentally,
['Now Brock you will be made the chief Pokémon Keeper for the Master and Mistress'] as she just smiled and began to blush.
While in the back room, Misty's masked form got in touch with her host as Misty returned to the crystal lake in her mind as she said,
"Yes Misty/Mask what is it?" she asked.
"I need to ask you something," replied Misty/Mask.
"What is it?" asked Misty.
"Well if you want to, we can be bonded together forever," explained Misty/Mask.
"You mean that I will never be able to take the mask off?" asked Misty.
"Yes but as of now you need to get Ashyboy masked so that you can help him become Pokémon Master," replied Misty/Mask.
"Create me two more masks and I will make the decision later tonight," replied Misty as her masked self created two more masks as Misty transformed back into her baggy trainer's clothes.
While Officer Jenny and May and Dawn also returned to normal but still under Misty/Masks control.
While in the main reception area, Nurse Joy turned to Brock and said,
"Will you come and help me please Brock look at this Pokémon that is very sick and will die if we don't do something," she said as she led him through to the back.
