The story starts with Ash, Brock, and Dawn are attempting to get through a forest when they run into Team Rocket.

"Not you guys again!" said Dawn.

(Skipping the motto because it's overrated)

 "What do you want now Team Rocket?" Ash asked.

"We have something to show you twerps." Jessie said holding a pokeball. "Come on out Rocketchu!" 

The pokeball then opened and it revealed to be another Pikachu but his tail tip was black and he wore the same accessories for TR.

Pikachu was shocked to see another Pikachu like him but scarier.

"What is that?" Brock asked.

"Well. Since we were tired of getting the twerp's Pikachu, we caught our own. His name is Rocketchu." Meowth said.

"Now Rocketchu! Attack the twerp with the Pikachu!" James commanded.

The evil Pikachu obeyed and ran towards Ash at full speed. Rocketchu then scratched at Ash's left eye causing him to scream in pain and bit him on his right arm. Pikachu saw his trainer scratched and bitten by the evil TR Pikachu. In rage, he punch his evil version of him straight back to Team Rocket and used thunderbolt on them causing Team Rocket to blast off again.

After Team Rocket and Rocketchu were dealt with, Pikachu ran to his trainer but what he saw made him gasp in horror. Ash was bleeding to where Rocketchu had attacked him. He covered his eye with his hand only for it to get covered in blood.

"Ash! Are you alright?!" Dawn asked after seeing her friend in critical danger.

"Unfortunately No. I'm not alright Dawn." Ash said.

"We better get you to the Pokecenter because you got hurt Ash." Brock said.

Ash nodded as the three trainers head to the Pokecenter. After they got there, Nurse Joy applied rubbing alcohol on Ash's wounds and wrapped bandages on them.

"I'm afraid that your friend has been hurt really bad from that evil Rocketchu. His wounds will heal in about several days." Nurse Joy said.

Dawn and Brock nodded as they understood everything.

Later that night, Brock and Dawn were in their own rooms to sleep while Pikachu stayed and slept on Ash's hospital bed.

While Ash lay in bed trying to sleep, he couldn't stop tossing and turning. While trying to get comfy, he got the most awful headache. It was almost as if two sharp objects were trying to push their way through his skull. He switched on the light and rubbed his head to make the pain go away. Then he noticed something as he looked at his hands only to find out that they were small and yellow now.

"MY HANDS!" he cried upon seeing his fingers much stubbier then before. Confused about what was happening he stared at one hand while rubbing his head with the other, but he nudged something. He wasn't wearing his hat so there shouldn't be anything up there. He slowly lifted his small, stubby and yellow hands above his head to see what it was. Upon his head were two long narrow furry ears. Ash began to panic, he didn't know what was happening to him. He ran out of his room and headed straight towards the bathroom. 

He slowly approached the mirror and saw his reflection making him gasped in horror. His cheeks were bright red with his Z marks in them. Suddenly a sharp pain shot up his back, it was much worse than his head pain and was coming from the base of his spine. His legs began to cave in on themselves he grabbed the side of a nearby sink for support to keep himself up.

"Why is this happening to me?!" Ash asked in pain.

The pain continued for only a minute but was enough to make him collapse on his knees. He also grew a long thin tail. Then he noticed that his clothing was getting larger on him.

"I'm shrinking!" Ash gasp in shocked.

His body began to pulse he collsaped on the floor his hands on his head. He continued to shrink as yellow fur all over his body with brown strips on his back. He was starting to lose consciousness as his vision was blurry. He lifted his small head and let out his scream of pain in the air.

"HELLLLLPPPPP!!!" Was his final word before passing out underneath his human clothes.

Hearing Ash's scream for help, Dawn, Brock, Nurse Joy and Pikachu woke up and ran to the source of the scream. When they got to the bathroom, they saw Ash's clothes on the floor.

"Ash isn't here." said Brock.

"Ash! Where are you?!" yells the now frantic Dawn.

"Hold on, there's something in the clothes." said Brock.

Pikachu then approaches Ash's clothing. He could see something hiding in the T-shirt. It moved and then another Pikachu with Ash's eyes, hair, Z marks and bandages when his scars were came out from the head of the T-shirt.

"Ugh. What happened?" The other Pikachu groan a bit after what the former human had gone through.

Pikachu and the two trainers gasped when they heard the other Pikachu spoke in a familiar voice.

"Ash! Is that you?!" Dawn asked while shocked.

"Pikapi?!" Pikachu asked the other Pikachu.

The other Pikachu now known as Ash heard his friends voices and looks up to them.

"Of course it's me." Ash said.

"I just can't believe this happened again." said Brock.

"This happened before?" Dawn asked.

"Yes you see, before we ever met you, we met a witch, and she told us that she could give Ash an ability to be able to go into Pikachu's mind. but she accidentally turned Ash into a Pikachu however the spell wore off." explained Brock.

"Now it happened again only this time, my clothes didn't transformed with me." Ash said while he was looking at his now small body.

"So what are we going to do now?" Dawn asked.

"Well we need to get back to sleep and tomorrow, we'll have to find a way to get Ash back to normal." Brock said.

Ash, Pikachu and Dawn agreed with what Brock said as they headed back to their respective rooms. Dawn carried and placed both Ash and Pikachu on their beds since Ash couldn't get on it anymore because he was small.

Ash then covered himself with a blanket and went back to sleep.
