It has been months ever since the events of Sonic Forces had happened, and since then, there has been no sign of the evil genius known as Dr. Eggman whatsoever. Sure, some of his robots rose up now and again to cause some mayhem, but those robots were easily taken out. And today, was just another peaceful day on the planet that the Mobians call home... At least, that is what they all thought. High above the atmosphere, a GIANT armada of space ships were flying over the planet. Their target? The planet itself of course! Most of the spaceships were just simple battleships, but in the middle of all those ships was an even more gigantic, red, flagship that was armed to the teeth with cannons, missile launchers, all sorts of guns and any sort of high damaging weaponry that one could think of! That ship, of course, was being flown and commanded by none other than the mad doctor himself; Who was laughing quite maniacally as his entire fleet neared the planet. For once, a plan was going smoothly without a certain blue pest coming to stop him! Unfortunately though, that luck didn't last much longer, as an explosion came from the front deck of the flagship, which immediately caught the attention of the mad scientist; Him looking through a security camera that was near the deck just to see who or what caused the explosion. And just as he expected, there he was... The blue blur, the savior of Mobius and another planet MULTIPLE times, and the fastest thing alive: Sonic the Hedgehog!

As usual, the green eyed and dark blue colored hedgehog was sporting his usual red vest, white t-shirt, white gloves, cyan pants and the familiar pair of red sneakers that each had a single white strap and a single golden buckle. And by the time Eggman looked through the security camera, Sonic had already gotten up to his feet; A serious look on his face as he looked towards the direction of the flagship's cockpit and whilst the ship's weapons were turning towards him. Though, instead of being angry or annoyed that the male teen speedster like the madman always was when he came to stop his plan, a grin actually came to his face! The evil genius was hoping that the blue blur would come to stop him, so he could put his true plan into action. And that grin only widened the moment the weapons of the ship pointed at the blue hedgehog, along with plenty of the Egg Fighter robots, some with shields and some with machine guns for arms, rose up from under the flagship's deck...

"FIRE!" Eggman screamed, doing his best to point at the hedgehog menace from all the way from the ship's cockpit.

Then, without even a moment's worth of hesitation, the cannons and whatnot from the flagship started to rapidly fire their ammo at Sonic; Who immediately boosted ahead without any sort of hesitation from him, the weapons instead blasting and causing some serious damage to the deck of the ship. But the male teen wasn't out of the woods yet, as he still had with the literal army of Egg Fighters in front of him! Yet being cocky as ever, all the blue blur could do is grin as he stopped in place and started to charge up a Spin Dash; Which only took a second or two before he blasted off toward the robots, bowling over any that happened to be in the way of the attack. Once that was done, he immediately jumped up from the Spin Dash and Homing Attacked a few more of the Egg Fighters in front of him before continuing to run towards the flagship's cockpit. As a result though, the mad scientist countered with even these giant Egg Fighters; Who proceeded to charge at the speedy hedgehog. This was simply another thing that didn't phase him in the slightest, as all he did was run around the robot to confuse them; Before jumping on top of run of them and waving at the other two to try and punch him. Of course, being programmed with what they were supposed to do, the other two giant Egg Fighters ran at the third on and proceeded to attack. Which in turn, made Sonic quickly jump off the third one as the other two took down the robot he just jumped off of.

"Heh, guess it's true what they say!" Sonic comments as he rubs the bottom his nose with the index finger of his left hand. "The bigger they are, the dumber they are!"

This, of course, caught the attention of the other two Egg Fighters; Them turning towards Sonic, who had yet another cocky grin on his face as he immediately boosted through one of them and into the other, easily taking them down before making one final dash towards the cockpit. But thanks to the failures of both his robots and the flagship's weaponry, Eggman decided to take matters into his own hands; Him dropping down in front of Sonic in a spider shaped mech, which he was able to shoot this sticky like goop from the front that looked simular to actual spider webbing even though it wasn't, able to shoot missiles from the sides and able to shoot grenades from the back. And just like a normal spider, the Egg Spider, which the madman called this contraption, was able to climb on walls and ceilings; Something that may be beneficial if he needed to chase after the teen male. Which he most likely did, since even with the arrival of the giant spider mech, that didn't stop the blue hedgehog from running towards it and performing a Homing Attack; Something that was quickly blocked off by a missile that was fired at him. And whilst said missile did make contact with him, the best it did was send him back towards the ground, daze him and slightly tear up his clothing; But nothing too serious as he managed to get back up to his feet with ease. Though, Eggman immediately saw that as a chance to trap Sonic before he could do anything else. So the second he got up to his feet, the evil genius immediately fired a bit of the mysterious webbing substance at the ground where the blue blur was going to land; Effectivelly trapping him where he stood.

Plus, try and struggle as he might, but there was no way that the speedy hedgehog was going to get himself outta this one with how sticky that gunk was; All whilst the evil genius' mech slowly got closer and closer, it ready to fire all its weaponry at once once it got super close to him. Sure, the male teen did survive the last attack, but an attack this close range from the madman's mech would most likely cure him. So having no other option, Sonic slowly closed his eyes as seven multicolored gems suddenly appeared around him and started to slowly go towards his body... The seven Chaos Emeralds, seven mystical gems that contained immense amounts of power; Which if it got into the hands of someone like Eggman, it could spell disaster for everyone. Luckily though, they were in the hands of the hero of Mobius, and he was about to use them to stop his schemes once more. So with a flash of bright like, the blue hedgehog's fur turned into a more golden color, his quills pointed upwards and his eyes went from their typical emerald green to a glimmering ruby red color. He was now, Super Sonic. But along with the transformation, the now golden hedgehog was able to easily break through the goop that trapped him and a grin formed on his face as he looked down at the now useless mech; Considering all of the madman's weapons have failed to injure the male teen whilst he was in his super form unless they were powered by something just as powerful, if not more powerful, than the Chaos Emeralds. But that all aside, the evil genius was waitng for the super speedster to do just this, so that way he would know if he had the Chaos Emeralds. All that was left was to lead him into a trap that the mad doctor had waiting for the powerful hedgehog...

"Time to go!" Eggman cried out as he ejected from his Egg Mobile, now quickly dashing away from the flagship in his hovercraft with Super Sonic following closely behind.

And whilst he was "escaping" from Super Sonic, an evil little smile formed on Eggman's face as he reached an all too familiar ship; Which was slightly damaged and a bit rusty from its last appearance, but it was still useable. It was the same ship that he used to awaken Dark Gaia all those years ago, and he was planning to use it again; Which meant very bad news to Super Sonic. Of course, the madman learnt from the mistakes of last time and would make sure that the speedy hero did NOT get exposed to the negative Chaos Energy like last time. So after managing to get himself into the main control room of the laser cannon spaceship, all he had to do was wait for the golden hedgehog to show up. Which he didn't have to wait long, as the super teen managed to bust through the doors of the control room; Where he saw the evil scientist waiting at the main control panel, which made him laugh as he walked over to him.

"Trying the same trick twice Eggman?" Super Sonic asked with a smug little grin on his face. "What? Did you run out of new toys to play with after I beat you last time?"

"Oh don't you worry Sonic..." Eggman spoke as he watched Sonic start to approach the middle of the room. "It won't end up like last time... Gotcha!"

Then without a moment of hesitation, Eggman immediately pressed a big red button on the control panel of the laser cannon; Which caused these odd looking panels to rise up and start glowing this odd looking lavender type color. Super Sonic, remembering this trick from last time this happened, attempted to quickly boost out of the way. Unfortunately like last time, he ended up getting captured by the machine and the Chaos Emeralds getting sucked out of his body almost immediately afterword; Which must have caused him quite a lot of pain as he was being forced to go back to his normal state! Though, before the machine went on to steal the power of the emeralds, it first trapped the blue blur in a metallic capsule; So he wouldn't be effected by all the negative energy.

"We don't want a repeat of that festive look of yours, now would we?" Eggman questioned with a grin as he watched the Chaos Emeralds start to lose their color and turn into nothing but dull and colorless stones.

And once the emeralds were fully drained of their power, a large grey button with seven multi-colored lights was able to be accessed by Eggman, who immediately pressed down on it; Expecting the laser to fire like last time... But unfortunately, that wasn't the case, as the laser didn't want to fire for some reason; Making him slam down on the button with his fist, multiple times.

"Come on you useless piece of junk! FIRE!" Eggman yelled out as he slammed down on the button one last time before a warning was heard being sent throughout the ship via its computer. "Warning! Warning! Energy unable to be released! Activate self destruct sequence! Evacuate immediately!"

But that wasn't about to stop Eggman. After pressing the button one last time, he was able to watch with glee as the cannon fired out a purple laser right down at Mobius. And as much as he wanted to enjoy seeing the planet breaking apart, again, he had no choice but to evacuate the ship; Unless he wanted all his plans to be futile because he didn't.

"Enjoy the fall, my spiky little frenenemy!" Eggman called out to Sonic, who had been trying to break out of the capsule ever since he got trapped in it; Him now opening the air lock to escape, which in turn, hurled Sonic and the powerless Chaos Emeralds towards the breaking up planet.

And whilst this was all happening, an aura resembling that of some sort of monster rose up from the core of the planet from between its now seven broken pieces. A creature of darkness and destruction: Dark Gaia. Who, just like when Eggman woke it up before, split apart and its energy spread across the entire planet. Though, it seemed to have had a bit more strength during this rude wake up call, so this time around, Mobius wasn't going to be the only place effected by what the mad scientist did...
