A person from Sonic's past warns him about something so big that he'll need special help. Mephiles and Nazo are the two most dangerous villains I could think of.

Ch.1 Threat to the Universe
Sonic was relaxing beside a tree. He had just finished a race with Shadow after destroying Eggman's base and he was too tired to run back home. So instead he decided to take a nap under one of the trees nearby. Amy was shopping at the time back at Station Square, so he didn't have to worry about her coming along.
Sonic knew it will take awhile for Eggman to finish repairing his base, so he didn't have to worry about him. He closed his eyes, about to take a nap.
"You should know evil is always hiding within the shadows… young Sonic," a familiar voice spoke.
"Huh, Wha…?" Sonic mumbled groggily, slowly opening his eyes.
In front of him was a green reptilian-like anteater mobian with a purple cloak.
"Oracle! Wow, it's been a while," Sonic stated, happy to see him.
"Yes, and I've seen that you've gone through much. But now I need you to gather your friends. There is something I must warn you of something," the Oracle said.
"Why? What is it?" Sonic asked.
The Oracle stepped closer and Sonic could see a serious look in the Oracle's eyes.
"There are going to be old enemies that will be a threat to the entire universe."

Sonic had gathered his friends and were sitting around in his living room. Amy, Blaze, Knuckles, Rouge, Shadow, Silver, and Tails were all there.
"Alright, Faker, what do you want us for?" Shadow demanded.
"To help defeat an evil that threatens you all."
Everyone but Sonic jumped as the Oracle appeared behind them out of nowhere.
"Wh-Who are you?" Tails stuttered.
"I am the Oracle of Delphius. I've known Sonic for a long time," he told him.
"Really?" Amy asked, skeptical.
"Indeed, but that is a story for another day. Right now there's something I must show you all," the Oracle announced.
He then showed them a vision of a dark gray hedgehog with light blue stripes and no mouth.
"Mephiles?!" Shadow shouted in disbelief.
"But I thought we got rid of him!" Silver blurted.
"When you defeated Solaris, it once again split into Mephiles and Iblis. The flame embodied only the Iblis half. And while Mephiles can no longer become Solaris, he is just as dangerous. And now he has joined with this hedgehog…" he informed them, switching the image to show a glowing light-blue hedgehog.
"It's Nazo!" Knuckles exclaimed.
"So you're saying that they're going to try to destroy the world again?" Blaze asked.
"Worse than that I'm afraid," the Oracle admitted as the image faded.
"These two are planning to use the Chaos Rift, a fixed point in space and time that can be accessed by our time and space once every millennium. It's an area of pure and absolute chaos energy. If someone were able to absorb and use its energy, they would have enough power to destroy the universe," he explained.
"Well then, let's go defeat them," Sonic announced.
"I'm afraid your super form alone won't be enough to stop them," the Oracle told him.
"What are we supposed to do about it then?!" Knuckles yelled.
"It isn't your only form. We'll need all of their help," the Oracle added.
"You don't mean…" Sonic whispered, wide eyed.
"In order to beat Mephiles and Nazo, you must join forces with all seven of your other forms."
Here's the first chapter. Sorry if the Oracle, or anyone else, is out of character. I don't know about the Oracle as much as the others as how he acts or talks, though I kinda know who he is. His other forms are: Super Sonic, Fleetway (Evil Super) Sonic, Hyper Sonic, Dark Sonic, Excalibur Sonic, and Darkspine Sonic and Werehog Sonic. Just to clear that up. The next chapter will show just how they're going to do that.
