Sonic the hedgehog was running through Green hill zone. It's been 5 years since the Time eater was trying to destroying time. But he was stopped by Sonic and Classic Sonic.

"I hope that it won't come back." The hedgehog saw that a dark purple chao with blue eyes, without pupils or wings on the path. The chao reached its' arm out, wanting to stop Sonic.

"Hey little guy, what do you want?" Sonic asked the chao. The purple chao said "Chao" over and over very fast.

"Um...Maybe you can show me the problem?" The chao nodded then walked to a cave under the waterfall. The cave was the typical cave. A bit dark, cold and have an empty feel.

"So what's the problem? Cause I don't want to keep my friends waiting." The chao stopped face Sonic with a grin, showing his fangs.

"What's with that look?" The creeped out hedgehog asked. Then everything in the cave was pitch black.

"What the heck is going on?" He felt a sudden headache as everything turns bright again.

"Why am I here? Oh shoot, the party!" Sonic rushed out of the cave to the fields where the party was. The blue hedgehog arrived to the fields where everyone hosted the party 5 years ago. The people there were Tails and Knuckles putting up the table where food and cake was.

"Hey guys, sorry I'm late." Sonic apologized with his usual smirk.

"You call a minute later, late?" Knuckles asked.

"Happy birthday Sonic." Tails said with a smile.

"Hey Tails." Sonic greeted. He noticed that all of the friends are not here.

"Where's everyone?" The hedgehog asked.

"Team Chaotix are on a assignment, Cream is at summer camp, pretty much almost everyone is busy today." Knuckles explained.

"Bummer. But at least you two are here." Sonic said with a smile.

"Actually, both Shadow and Amy are here too." Tails informed.

"I get Amy but Shads?" The hedgehog saw Shadow resting against a tree that was behind the table. And Shadow was reading.

"Where's Ames?" Sonic asked.

"Right here!" He turned to see Amy but wearing a new outfit. She had a pink short-sleeve shirt with a blue stripe. Yellow shorts with pink hearts, two green bracelets in each wrist. pink boots, pink socks and a pink hat.

"I decided to change my outfit. What do you think?" Amy asked.

"It's cool." Sonic commented before eating a chili dog from the table.

"Thanks! Here's your present." The pink hedgehog handed Sonic a purple tarot card with a picture of two shadowed lovers holding hands. The bottom says "True lovers" and have a red ribbon around it.

"Without this card, then I wouldn't fell in love with you. I trust you to take care of this." The pink hedgehog said with a smile.

"Don't worry, I'll take care of this." Sonic said before slipping the card in his left glove. Shadow was in the shade still reading the book. He had a day off from G.U.N and Rouge forced him to go to party. Sonic, Tails, Knuckles and Amy sit at the table.

"I wonder if the Zeties are still at the Lost Hex?" Tails asked looking up at the planet above.

"Who are they? Are they a band or something?" After Sonic asked that, Lost Hex started glitching then fully disappeared.

"W-What?! Where's Lost Hex?!" Tails shouted with his eyes widened. Shadow heard the commotion and came to them.

"What's going on?" Shadow asked.

"The Lost Hex is gone!" Amy shouted pointed to the now gone planet.

"Do you think it's Eggman?" Knuckles guessed.

"I don't think so. Why would he make the Lost Hex disappear? It disappeared when Sonic didn't remember..." Everyone turned to Sonic.

"What?" The confused hedgehog asked. Then a blue portal appeared, spitting out a silver hedgehog which falls to the grassy ground.

"Ow! I need to get used to that." The silver hedgehog said before getting up.

"You're Blaze's friend, right?" Amy asked.

"Yep, Silver. Then again it's been 5 years since I seen all of you." Silver said.

"Why are you here?" The echidna asked.

"I'm here because the timeline is messing up and I'm here to fix it." Silver explained.

"You mean like a paradox?" Tails asked.

"Yes and it got something to do with Sonic." Everyone turned to Sonic again.

"Wait, I can make paradoxes?!" The blue hedgehog asked freaking out.

"Well you can't make them but it's got to do with you." The time traveler said.

"He said that he doesn't remember the Zeties then the Lost Hex disappeared." Tails informed.

"Interesting." Silver commented.

"Sonic, what did you do before coming here?" Shadow asked with his arms crossed.

"All I remember is that I was in a cave in Green hill zone and I had a headache." Sonic explained.

"Show us the cave." Silver said. Sonic nodded then sped off

"And slow down!" Knuckles shouted. Sonic stopped and gave a silly smile. They soon arrived then Sonic had a flash of memory

"Hold it!" Sonic shouted, getting everyone attention.

"What is it?" Amy asked.

"I remember clearly. There was a purple chao without pupils or wings that wanted my help and wanted me to follow it to this cave. But, it gave me a creepy smile before the lights went off." The blue hedgehog explained.

"Where's the chao now?" Tails asked. Sonic only shrugged.

"Purple chao...Without wings..." Silver gasped when he figured it out.

"What's up?" Shadow asked.

"That chao, is the Time eater." The time traveler said to everyone.

"But little me and I defected him. How did he came back?" Sonic asked.

"My mentor had a vision like this. After you two defeated him, he traveled 5 years in the future to escape. But do to the weakness, he turned into a chao until he'll be full again." Silver explained.

"If he's weak now then how in Mobius is he make paradoxes?" Knuckles asked.

"He went into Sonic's memories to make him forget all of his adventures. It effects the timeline and makes the adventures even friends disappear." The time traveler explained.

"You're saying that I'll forget everything? Even all of my friends?" Sonic asked.

"Yes but if we go through your memories then we might stop him before you'll forget." Silver said.

"Alright let's go!" Amy shouted.

"I'm afraid all of you can't go." Silver said feeling kind of bad.

"Why not?" Knuckles asked.

"Well Shadow is the only one that use the emeralds, I know about time and Sonic will guides us in his memories." Silver explained.

"You're saying that I have to come?" The ultimate life form said with an annoyed look.

"I'm afraid so." Silver said.

"Let's get this over with." Shadow said pulling out a green emerald.

"Good luck you three." Knuckles said.

"Thanks. I promise that I won't forget all of you." Sonic promised. "And we'll be back in no time. Get it?" Everyone looked at him with annoyed looks.

"Don't push it." Amy said.

"Chaos control!" A blue portal appeared then both Silver and Shadow went through

"We might not make it but as long as all of you are okay." Sonic said. Half of Shadow went through the portal and grabbed Sonic.

"Get over here!" Then both were gone and the portal disappeared.

"I hope they'll be alright." Tails said.

I hope you like this first chapter! I had this idea ever since in May and I waited for 2016 to be Sonic's 25th anniversary. The idea for the Time eater being a chao was a rumor for Sonic runners that Chaos was going to a chao and later it'll be full again. I decided to do that but for Time eater. Each chapter will be in the order of main Sonic games like next will be Colors, Black knight and so on. I hope you like this so far and have a good day :)
