Ash, Clemont, Serena, Bonnie, and an Officer Jenny were in pursuit of a Malamar that had been causing problems. It had mind controlled the Jenny, and used her to be its figure-head in its attempt at world domination. It then proceeded to take control of Jessie and James (along with their Pokémon), followed by, Clemont, Bonnie, Dedene, and Serena, with only Ash and Meowth not controlled. Ash and one of Clemont's malfunctioning inventions had broken the control, and the Malamar tried to escape.
"Stop right now!" The Officer Jenny ordered.
"You may have foiled this plain, but it isn't the only end,you've just delayed my victory. This world will be mine!" Malamar scoffed.
"Whatever your planning, we won't let you win!" Pikachu replied.
Malamar didn't reply, it only smirked and charged a Psybeam, pointing towards Ash and his friends, while charging the energy for mind control into it.
"Pikachu! Use Electro Ball, and throw it with Iron Tail!" Pikachu obeyed and used the combination of moves as the Malamar shot out a Psybeam. The two attacks collided, and at first, both moves seemed equal, but soon, the Electro Ball broke through and hit the Malamar. The weakened and disrupted Psybeam baunced in the walls of the cavern and changed the trajectory to the girls.
Ash ran quickly to protect them, using his body as a shield. The Psybeam hit Ash, who subconsciously flared his aura to prevent the mind control, and three little beams, looking like a cross between the Psybeam and aura, came out of Ash, and struck Serena, Bonnie, and the Officer Jenny, causing all four to faint. At same time, the Malamar crashed to the ground, and Clemont thought quickly.
"Bunnelby use Wild Charge!" The rabbit used the electric attack, weakening the Malamar. Clemont threw out an Ultra Ball he had stored just in case, catching it. Next he called to an ambulance for help to Ash, Serena, Bonnie, and the Officer Jenny.

Several hours later, the three girls woke up in a Pokémon Center.
"Where am I? The last thing that I remember was that Malamar tried to attack us..."  The Officer Jenny began, before getting a shocked look as she covered her mouth with her hands.
"My head is killing me!" Serena complained as she rubbed her head, but noticed something about her hair that confused her as she began to examine it, pulling a strand in front of her face.
"Where's Pikachu...?" Bonnie asked, before getting a confused look, similar to the other girls. "Wait a minute, why does my voice sound like this? 
"Bonnie are you ok?" Serena asked, a bit worried.
"I'm fine, but why'd you call me Bonnie, Serena?" The youngest girl asked.
"Serena? What are you talking about, I'm Ash!"
"No you aren't! I'm Ash" The Officer Jenny argued. The girls stared at each other very confused for some minutes.
"How's that possible? I'm know that I'm Ash Ketchum, but apparently, you two are too." 'Bonnie' questioned.
"The last thing that I remember was trying to protect Serena, Bonnie, and Officer Jenny from that Psybeam." 'Serena' mentioned.
"I remember feeling weird when that Psybeam hit me... us... whatever, and it then hit the girls... Maybe it copied my our mind into their bodies." 'Bonnie' suggested with a shrug. The other Ashes just stared at 'Bonnie' in astonishment, because even though Ash is far smarter than a lot of people give him credit for, that was still amazing. "What? Even though I have the mind of Ash, I also have Bonnie's brain, and she rivals her brother's intelligence."
"Now, the question is, where is our original body?" 'Serena' mused.
"I'll take care of that." 'Officer Jenny,' replied, putting her shoes and standing up to exit the room. At first, she had difficulties walking with the heels, but she quickly got the hang of it, due to muscle memory from the real Officer Jenny. A few minutes later the 'Officer Jenny' returned to the room with a Nurse Joy, the nurse made them take a medical test, and said that they were apparently fine, but she wanted the girls to stay in the Pokémon Center for a couple of more days, just to be safe. She also told them that Clemont had been forced to leave to visit Professor Sycamore, so that they could decide the fate of Malamar. Finally, the Nurse Joy told them that Ash was unconscious, but fine, and would hopefully wake up soon since they had all woken up at about the same time.
"Do you think we could see Ash?" 'Officer Jenny' asked, the three girls having decided to keep the whole thing a secret for the time being. Nurse Joy led them to the room Ash's body was kept in, all the way, the girls were fidgeting a little, not used to their new bodies, plus the alien feeling of wearing skirts. Upon getting into the room, they convinced the Nurse Joy that let them be alone with "Ash." They had to discover just who is in their original body.
