At Lair of the Time Eater the Time Eater floated, as both Sonics and both Tails ran or flew up to it.

"Okay, whatever you are. If you want to avoid an embarrassing beat down, you'd better give up now!" Modern Sonic said.

Then one of the spheres on the Time Eater opened, revealing Modern Eggman.

"You're not in a position to demand anything, you nasty little pincushion!" Modern Eggman said.

"Eggman! But, how?" Modern Tails asked.

Then another sphere opened, revealing Classic Eggman.

"He had a little help." Classic Eggman said.

"Dr. Robotnik!" Classic Tails said.

"Nobody calls me that anymore. If you would be so kind as to explain, gentleman genius Dr. Eggman From The Future."

"It will be my pleasure, most excellent and efficacious Dr. Eggman from the Past." Modern Eggman said.

In a flashback Orbot and Cubot were pushing the Egg Mobile through space, with Eggman inside. They found the Time Eater, which Eggman scanned. Impressed with what he had found, Eggman flew towards the Time Eater.

"After my most recent setback, I stumbled upon the primordial form of this unique creation. Which I discovered had amazing abilities even I have never been able to master. It could erase time and space! I then had the brilliant idea to use my discovery to undo my previous defeats!" Modern Eggman said and the flashback ended.

"In order to perfect it, I needed the help of someone as smart as I am. The only person that smart... is me!"

"Oh, you are too kind, my dear future self! And I was happy to help." Classic Eggman said.

"I captured your friends, flinging them through time to bait my traps."

"But the more your monster tears through time, the more damage you do to the world!" Modern Tails said.

"The world? I'm going to own the world when I'm finished with Sonic!" Modern Eggman said and burst into maniacal laughter, which was interrupted by coughing and clearing his throat, then more laughter.

"Wow. Will I really get that crazy?" Classic Eggman asked.

"Heheh. We'll see who's crazy after I destroy both Sonics... forever!"

"You mean after we destroy them."

"Less arguing. More destroying."

"Destroy me? You and what mustache? I beat you all the time by myself, and now there's two of me!" Modern Sonic said and Classic Sonic back flipped.

"Then I'll have twice as much fun defeating you!"

Then the cockpits resealed themselves, and the Time Eater started blasting at the Sonics, who split up and ran in different directions.

"Keep moving!" Modern Sonic said.

"Move all you want! I'm still going to stomp you into a blue jelly." Modern Eggman said.

One of the Time Eater's arms disappeared into a Time Hole. Both Sonics jumped and tried to attack the Time Eater, but got knocked away. Before they could recover, the disappeared arm reappeared and smashed them into the ground.

"That was just to soften you up. Now it's time to meet your doom." Modern Eggman said and the Time Eater got ready to strike.

"You can do it, Sonic!" Amy said.

"Come on, Sonic. Smack him!" Knuckles said.

"Ugh. not you!" Modern Eggman said.

Shadow was standing and looking as Rouge flew down next to him.

"You got this, Sonic!" Shadow said.

"You can win, Sonic!" Rouge said.

"Who are they?!" Classic Eggman asked.

"They are insignificant!" Modern Eggman said.

Then Vector and Espio ran up and Charmy flew in.

"You got the power, Sonic!" Vector said.

"Focus your spirit!" Espio said.

"We're with you guys!"

Cream and Cheese were looking on while Blaze ran up and Silver flew in.

"I believe in you, Sonic!" Cream said.

"Don't give in, Sonic!" Blaze said.

"I know you can do it, Sonic!" Silver said.

"You can win, Sonic!" Classic Tails said.

"You always do!" Modern Tails said.

The Chaos Emeralds suddenly appeared, swirl around both Classic and Modern Sonic, and lift them into the air. Regaining consciousness, Modern Sonic clenched her fist as the Emeralds power her up.

"Time to scramble some Eggmen, SUPER SONIC STYLE!" Modern Sonic said and they transformed into their Super, then flew towards the Time Eater.

In Modern Sonic's meadow Sonic's chili dog dropped from the sky and into her hand. Sonic then smelled it and took another bite out of it.

"Still warm." she said then laughed and threw the chili dog into the air, then caught it. "Time travel!"

Then Classic Sonic ran up to Modern Sonic. Suddenly, a mysterious sound was heard and they looked as all their friends appeared. Everyone cheered in relief at their victory.

"I'll admit. You weren't half bad Sonic." Knuckles sad.

"Half bad? Are you kidding?" Amy said flabbergasted. "She was all great!" she said and smacked him into a tree.

Knuckles was stunned.

Then Classic and Modern Tails walked up to the party while talking to each other.

"He collects how many? Wow, where does somebody put all those gold rings?" Classic Tails asked.

"You know what? I don't know. I keep forgetting to ask." Modern Tails said.

Later Espio talked with Vector and Charmy, Knuckles talked with Rouge, Silver, Blaze, and Shadow talked with each other, and Amy, Cream, and Cheese talked to both Modern and Classic Tails, while Modern Sonic talked with her past self.

"It was great teaming up with you. Hope you learned a few tricks that will help you out in the future. I mean the past. You know what I mean." Modern Sonic said.

Classic Sonic nodded and pointed at herself pompously. Then she ran and jumped, trying to do an Air Boost, but only for a split second. She stood in mid air and then fell down, landing on her head.]

"Dude, sweet! And you're only going to get better." Modern said and Classic ran up to her while she talked, and then Modern and Classic Tails walked up.

"There's our ride!" Classic Tails said.

A Time Hole was seen leading to Green Hill. Classic and Modern Sonic and Tails high five and ten each other. Classic Sonic and Tails ran to the portal. Amy, Knuckles, Shadow, Rouge, Cream and Cheese, Blaze, and Silver looked watched. Espio, Vector, Charmy and Knuckles waved goodbye, followed by Cream and Cheese, Amy, Rouge, Blaze and Silver while Shadow just looked.

"Hey Sonic! Enjoy your future. It's gonna be great!" Modern Sonic said.

Classic Sonic gave a thumbs up as she and Classic Tails jumped into the portal and it disappeared, as Modern Tails and the rest still waved, while Sonic just looked on.

Later Modern Eggman was trapped in White Space looking exhausted.

He looked at Classic Eggman and growled.

"Are you sure you saw a door over here?" he asked.

"What?! You were the one who said you saw a door over here." Classic Eggman said.

"Well, I know it was one of us. Shut up and keep looking."

They had a silent argument, then walked off in different directions. Later, they were laying on the ground near each other.

"What time is it?" Classic Eggman asked.

"It's the exact same time when you asked earlier and it will be the exact same time when you ask later. There is no time here!" Modern Eggman said.

"Let me just say that this was a brilliant plan that you came up with."

"Don't get too self-righteous. It'll be your plan pretty soon." Modern said and pointed at Classic.

"I'm going to dedicate the rest of my life to forgetting it." Classic said the screen breaking the fourth wall.

"I heard that."

"Do we ever win?"

"That depends on your definition of "win"."

"Beating Sonic."

Modern bent down and put one hand on his head.

"Oh, well, then no." he said.

"That doesn't give me much hope. Maybe I'll go back and get my teaching degree."

Modern got up.

"That's not a bad idea. I've always enjoyed telling people what to do." he said and Classic shook his head in the background.
