New world, same hero.

Mobius, a peaceful planet full of beautiful landscapes and inhabitants living in harmony thanks to a dedicated group of brave individuals known as "The Resistance" and a courageous hero named "Sonic the Hedgehog". This hedgehog was now resting in the shade of a palm tree, accompanied by his friends and adventure companions, Tails Prower, a young orange fox with an unusual second tail that allows him to fly, and his great ingenuity and skill with all kinds of tools. This fox doesn't fall behind when it comes to facing his enemies. Outside the rest area was Knuckles the Echidna, a solitary warrior and guardian with long dreadlocks and red fur, his hands adorned with spiked gloves on his knuckles, honoring his name.

"Is something bothering you, Knuckles? Come over here and relax. You're taking a break from your duties, and it’s not like the end of the world is going to happen just because you’ve left Angel Island for a while," Sonic said with a relaxed smile, resting his hands behind his head as pillows against the palm tree.

Knuckles only grunted and turned his head, looking at him over his shoulder with his eyes closed. "It's the Master Emerald we're talking about, Sonic. Eggman hasn't shown up in a long time, and I'm worried he might reappear just when I decide to leave my post as guardian." After his comment, he returned to focusing, continuing his meditation.

Sonic looked at Tails, and after exchanging a glance, they both shrugged, enjoying their day of relaxation. A few seconds later, Knuckles felt a disturbance in his connection to the Master Emerald. He grunted in frustration and quickly stood up, looking toward the horizon where he knew the problem lay. "Sonic! Tails! Get up! The Master Emerald is in danger!"

Both of them immediately stood up, surprised to see that Sonic's mocking prediction had come true. "Well, I guess it might be the end of the world after all for you to leave the Master Emerald unguarded," said Sonic, shrugging. With the "Tornado", a red biplane with the word "Sonic" written on its sides, Tails quickly mounted it, started the engine, and put on his aviator goggles, showcasing his leadership and skill in piloting the aircraft.

Knuckles quickly ran to the plane, jumping into the back seat, and as it began to accelerate, Sonic stood up, stretching his arms and legs while watching them take off, moving back to give the plane enough space to gain altitude. The arrogant hedgehog smiled, then suddenly disappeared from the shade of the palm tree to run alongside the plane. A huge jump with great precision allowed him to leap onto the upper wing, holding on tightly and keeping himself angled to avoid being blown away by the powerful wind.

"Alright, team, let's give it everything we've got!" The plane accelerated and took off, turning in the direction of Angel Island, the air route leading toward the floating island.

Angel Island

On the floating island known as Angel Island, a flying fortress was retreating, descending toward the open sea.

"I see the problem, Knux. Eggman and the Death Egg are back after all these years," exclaimed Sonic from the wing of the plane, looking at his friends.

"The Death Egg? I thought we destroyed it after we infiltrated it when he stole the Master Emerald years ago and we retrieved it with the Chaos Emeralds," Tails pointed out as they gained altitude and headed toward the flying fortress.

"Tails, can you make this thing go faster!?" complained Knuckles, slamming his palm against the side of the plane, desperate about the situation.

"Don't worry, I'll handle it. You guys stay back. I'll be back in a moment!" Sonic shouted, showing the Chaos Emeralds floating around him. They merged with him, and he transformed into Super Sonic, taking off toward the enemy's fortress.

"Sonic, take the Master Emerald to the island!" shouted Knuckles as he watched Sonic disappear, leaving a golden trail in the sky before reaching space, outside the planet's atmosphere.

As both headed toward Angel Island, a bright flash illuminated the sky. The Death Egg shone like a sun, radiating energy until it blinded Tails while piloting the plane. The enemy fortress had disappeared into space, and they couldn’t see any signs of their friend. What they saw left them with many questions as they landed on Angel Island, which rested in the calm Pacific sea.

"That was the Chaos Control, wasn’t it?" Tails looked at Knuckles as they disembarked from the plane on the island, analyzing the situation.

Tails stared at the sky, seeing no trace of their friend or the Death Egg, only the blue sky and clouds. "Knuckles... do you think Sonic will be alright?"

"Knowing him, if he used Chaos Control, it could have taken him to some unimaginable place, but he always finds a way to return from whatever trouble he's in."

"I hope everything turns out fine. I have a bad feeling about this."

Both looked to the sky as the wind and the sun provided the peaceful atmosphere of the island, waiting for some sign, but all they found was emptiness and mystery. Where could they have gone?

Moments before - Death Egg

Sonic tore through much of the robotic defenses, racing through the fortress at high speed, arriving at the control room where Eggman was waiting for him, seated and focused on his computer screen, wearing a confident smile.

"Sonic! As nosy as always. Have you ever thought about leaving me alone?" Eggman snapped his fingers, and the Master Emerald emerged from the ground on a platform connected to it. "This is what you're after, isn't it? You can take it."

"That's what I like about you, Eggman. Cooperating and without violence. I like it when we can settle things without having a battle." Sonic approached slowly to touch the Emerald, but as soon as he tried, he was hit with a powerful shock that made him stagger back in his Super form, revealing how the large gem was covered by an energy barrier powered by the Emerald itself.

"Only if you can get past it, ho ho ho. You didn’t think I’d make it that easy, did you, Sonic?" Eggman hit a big green button, encasing himself in a protective capsule as the Emerald began to release energy through a network of connections beneath it. The entire fortress started to tremble, and a bright flash blinded both of them for a moment. After a second, Sonic opened his eyes, feeling that his body and mind weren’t in sync anymore.

Sonic tried to break through the barrier with his hands, but the energy from the Emerald repelled him. The longer he made contact with it, the more power he needed to get closer. "Don’t think you’re getting away with this, Eggman! Even in my Super form, I can’t break through this barrier? The Master Emerald itself is keeping it active, and its own power is what’s protecting it."

The iconic gloves of the hedgehog began to lose their Super form's glow, and small bits of fabric began to tear, showing how trying to release the Emerald with his bare hands was becoming dangerous.

"Oh ho ho ho! Too late, Sonic! Right now, the Master Emerald is not only protecting itself and obeying the system it's connected to, but it's also powering up the entire Death Egg for my next plan! I’m going to take a vacation far away from you and your annoying friends. Right now, we’re traveling beyond your beloved planet, looking for a place where you won’t be able to bother me."

A large screen appeared behind Sonic, showing the view from outside the Death Egg, where stars and planets seemed to disappear in flashes of light. It didn’t take long for Sonic to realize they were traveling at light speed, moving millions of kilometers away from Mobius. "So that’s why you needed the Master Emerald. You wanted to take something to remind us of you, huh?" Sonic smiled and managed to stand, regaining his balance to approach the Master Emerald.

"Try all you want, Sonic, not even your Super form will be enough! The Master Emerald is protecting itself from you and anyone who tries to reach it. This barrier was programmed and powered up to only be deactivated by the Emerald itself, but it won’t be possible because of its infinite power, infinite barrier, and infinite energy." Eggman watched as his stubborn enemy attempted again to break through with his bare hands.

Sonic stepped back, seeing the damage to his gloves and clenched his fists, frustrated by the situation. He analyzed the control room, noting that only Eggman and the Master Emerald were protected. "A vacation, huh? Will there be room for one more?" He crossed his arms, a smile of excitement on his face as he channeled energy around his body, which became surrounded by a golden aura. He then extended his arms, releasing a blast of energy that struck everything around him, causing massive damage to the systems.

"Nooo! What are you doing!? Stop, you cursed hedgehog! You’re ruining my work!" Eggman could only watch as the entire control room took heavy damage, forcing him to accelerate his plan.

"Hehe, that’s the idea! Your vacation plans are getting canceled." Sonic’s attack ended as he aimed both hands at the Master Emerald, concentrating more energy into his hands. He approached with force, managing to breach the barrier with difficulty, ultimately grabbing the Emerald while resisting as it denied him more power from the Chaos Emeralds, causing subtle changes between his Super form and his normal state. "Hey, Eggman!"

Eggman looked down, seeing his nemesis smiling while holding the large gem and resisting the damage of the barrier created by the Emerald itself. "You may think the idea of the Master Emerald protecting itself from even the Chaos Emeralds is a good one, but don’t forget who you’re dealing with!" Sonic began to pull the Master Emerald, feeling his Super form slowly fading, forcing him to leave it inside of the barrier, but refusing to let go.

"It’s true. You are a tenacious opponent, Sonic, but not even you can stop this! Chaos Control!" Eggman shouted as he pressed a rainbow-colored button on his console, causing the Master Emerald to release a massive amount of energy, creating a bright flash throughout the ship.

"Not so fast! Two can play at that game, Eggman! Chaos Control!"

Hoping to be quicker with his natural Chaos Control, Sonic risked using his own while Eggman’s was much stronger, powered by the infinite energy of the Master Emerald. The clash of both energies distorted space and time throughout the fortress.

"Look at what you’ve done, you insufferable hedgehog!" Eggman yelled as he felt the Death Egg shaking from the collision of the two energy sources.

Sonic just kept smiling, maintaining his Super form, until he was repelled by the massive energy discharge from the Master Emerald, radiating a blinding light that made it disappear mid-flight across space, which threw him across the ship. The same Emerald that powered the ship disappeared in a flash of light, leaving Eggman without a direction, losing the Master Emerald, the Chaos Emeralds, and his nemesis all in an instant.

Present - Death Egg

The Death Egg ended up appearing near what seemed to be a "moon" close to a planet, finally landing on its dark side as a last resort to analyze the current situation. Before he could vent his frustration on his control panel, a small spherical robot appeared, calmly observing the situation before looking back at its enraged creator.

"Sir, I know the current situation may not be what you had planned, but look at the bright side."

Eggman stopped his outburst and glared with fury in his eyes while lowering his fist and standing up to grab the robot’s thin body, pulling it away from the console. "What bright side? Tell me something good about what’s happened before I use you as a flagpole to mark this cold rock as my property!"

"Sir, Sonic the Hedgehog is no longer here. Yes, we lost all the Chaos Emeralds along with the Master Emerald, but we are far from Mobius, or any constellation known to your great genius. Taking away the loss of the Emeralds, your Death Egg is still operational. We are in a new and unknown place to you, the inhabitants here don’t know who you are, your army is still operational, and Sonic is lost, who knows where, or how far we are from him."

Eggman paused, listening, and before punching the robot, he stopped and let out a sigh to calm himself. "If that sounds like good news, then I want something better. Send in the investigation squad! I want to know what I’m going to conquer and what resources I can use to my benefit." He released Orbot, who reconnected to the console and carried out his orders via the main system.

???

On a dark night, illuminated by the moonlight in a clear sky that led toward the stars, a sonic explosion made its presence known upon entering the atmosphere, leaving a trail of golden light that traveled through the night sky like a shooting star. Those who were still awake at that moment witnessed the event as the golden trail turned blue, and it seemed as though a rainbow of stars accompanied it, before dispersing into seven different directions. As the blue trail fell faster toward a castle atop a mountain.

Sonic felt the breeze of the air flowing across his body. It didn’t take long for him to open his eyes and realize he was about to crash into what appeared to be a large, elegant castle on the edge of a mountain. "AAAAAAAAAAGH!!" His scream was heard as he noticed how close he was to crashing into the castle's roof, hearing screams of terror.

After a moment, his limbs hit the ground, signaling him to position himself and push with his arms and legs, lifting his face from the crater he had formed. "Face first... why do I always land face-first wherever I fall?" He shook his head to remove the debris from the ceiling and floor against which he impacted and quickly regained his composure, noticing that he wasn’t alone, and his vision was a bit blurry. He quickly recovered and saw who surrounded him.

"Are those... ponies in dresses?" He wondered as he rose from the crater he had created upon landing, relieved that he hadn’t hurt anyone with his impact. The first thing he noticed was how everyone present backed away in fear at his presence.

His ears perked up at the sound of quick, heavy footsteps that caught his attention. A group of ponies in armor approached, brandishing their spears at him.

"Halt, intruder! You’ve just invaded the royal castle and the Grand Galloping Gala!"

Sonic simply raised his hands, showing the damaged palms of his gloves, staying calm in front of the group of guards and analyzing his surroundings, planning his next move.

"Who... and what are you?" The guards kept their eyes on him while whispers spread among the guests witnessing the scene.

"Eeh... Mew?
