Sonic was running through a forest, when suddenly he saw something shiny. He stopped and notices it was a green Chaos Emerald, but some creature was holding it. A small mouse that was yellow with black tipped ears, and red cheek pouches. Sonic was about to take the Chaos Emerald away from the mouse, when the mouse produced electricity from his body and shocked Sonic.

"What are you?" Sonic asked getting up from being shocked with electricity.

All the mouse said is "Pika, Pikachu."

"So you're called a Pikachu. Wow, you sure can produce a powerful thunderbolt," Sonic said rubbing his head.

"Now can you give me that Chaos Emerald now," said Sonic, while putting his hand out to tried to take it, but Pikachu shook his head and ran up a tree.

"Come on little guy, give it to me." Sonic inched closer to the Pikachu who was still holding the Chaos Emerald in the tree. Sonic would have use speed to get the Chaos Emerald back but didn't want to get shocked or scared the Pikachu. He was getting aggravated though, so decided to take it away from the Pikachu.

Though suddenly the Chaos Emerald started to glow, and Pikachu was started to getting transported somewhere else using Chaos controls.

"Crap, you're not getting away," Sonic said as he also got transported too.

Sonic fell unconscious from transporting to a different world and Pikachu was still holding onto the Chaos Emerald.

Pikachu was happy about getting back to its world, and started to look around for Ash. Sonic woke up after some time pass, and got up to look around. He found himself in a grassland in an open field.

Where am I, he was thinking.

He started to walk around until he heard someone yell, "Pikachu, where are you?." A black hair boy appeared with a red and blue outfit with some black on it. A girl with blue hair and white hat followed, and another guy that had spiky brown hair, and darker skin.

Maybe it was that guy's Pikachu.

The three kids turned around, and saw Sonic looking at them.

"That looks like a really weird Pokemon," the black hair boy said.

"Hey, I can understand you," Sonic said glaring at them.

"Holy Shit! It can talk it," the black boy said.

"Ash, be nice," the blue hair girl said with a little penguin, shaking in fear, behind her.

"Hey, have you happen to see a Pikachu with some kind of jewel?" the dark skin guy asked.

"Uh no, I was looking for one though, since it has my Chaos Emerald and it is the only way I can get back to my world," Sonic said.

"You are from a different world? Well don't worry, I'm sure Pikachu is around here somewhere, and by the way my names Ash, this is Dawn, and Brock," Ash said while pointing to the girl and the other guy.

Suddenly Pikachu comes out of the bushes with the Chaos Emerald.

"Pikachu, give that back to….," Ash said wondering.

Sonic said, "My name is Sonic."

"Oh, yeah, give it back to Sonic," Ash said while trying to get the Chaos Emerald, but Pikachu kept jumping out of the way.

"Come on, Pikachu," Ash said getting aggravated.

"Hey, wait a second Ash. I got an idea," said Dawn. She brought out a circular red and white object with a circle in the middle and called out "Buneary."

Buneary came out and tackled Pikachu, making him drop the Chaos Emerald.

"Thanks," said Sonic, while picking up the Chaos Emerald.

"You're welcome," said Dawn.

Sonic said "Chaos control," and got sent back to his world, while Buneary kept bothering Pikachu.

The end.
