It has been many years since Dr. Robotnik have conquered Mobotropolis and turned the beautiful city into a nightmarish robotic shell of its former self. The king of the city was banished into the void, a limitless space of nothingness. Former inhabitants of the city who escaped Robotnik from turning into mindless robots fled to the hidden village of Knothole in the Great Forest.

Younger Sonic and Sally, one of the Mobians who escaped Robotnik, formed a resistance group that came to be known as the "Knothole Freedom Fighters". The group had done successful raids, sabotages and destroying factories on Robotnik-controlled Mobotropolis, now renamed to Robotropolis by the mad scientist himself, thanks to Sonic's speed and Sally's leadership.

However, Dr. Robotnik wasn't affected by this as he was working on a project that could have destroyed the group, its members and conquered the rest of Mobius. It wasn't until an event stopped such thing to happen and saved the Freedom Fighters from their doom. This event came to be known as "The portal that brought hope."

…

Sonic laid on a tree branch like he usually does with both his eyes closed and having a little smirk on his face. The wind slightly, but softly brushing against his blue fur. The day was beautiful in Knothole as usual.

His nap was interrupted when someone was knocking on the tree and a familiar voice started calling his name. "Sonic! Get down here! We need to discuss something." The blue hedgehog opened his eyes before looking at the yellow ground bellow him. It was Sally Acorn, his friend.

Sonic stood up on the branch and ran down to the ground and then stopped next to Sally. "What's up, Sally? Something new from Robuttnik?" Sonic joked while sounding serious at the same time.

"We got report that Ivo Robotnik making a new machine. We don't know what it is or what it does."

Sonic smirks before responding "It's probably another one of his badniks that will be easy to destroy."

"Maybe, but we still don't know what this robot or machine is or what it does. It probably could wipe us out and everyone in Knothole. We need to tell everyone about this in Knothole. Let's go!"

Sonic nodded in agreement before the two walked back to Knothole.

…

Something strange was happening somewhere in the Great Woods. Something opened up in the woods. A portal. The portal was blowing something out of it, causing grasses, bushes and flowers to flail backwards like a reverse vacuum.

Something or someone came out of the portal with something glowing blue before it closed behind the thing/person. The leaves on the trees blocked out the sunlight, making the figure hard to make out. The figure however stepped into a lone shinning sunlight that penetrated through a gap in the tree's leaves, brightening up the grass that got caught by it.

The thing was a male red-furred dog that looked he was in his mid-teens. His clothing consisted of a green shirt and dark blue jeans. The dog looked around his surrounding with a hint of confusion. "Where the hell am I? This doesn't look like my town." Then something glowed below his eyesight. He looks down to see that he was holding a glowing blue emerald in his right hand. He raises it up his face, observing it. "Did this bring me here?" He inspected the gem for a while until he decided to put it in his soft pocket, making contact with its material, before pulling his hand out from it.

"Now, where should I go?" He wondered what direction he should go. But his thoughts were interrupted when his ears picked up something. Noises. It sounded like people chattering and it wasn't far from where he was.

He started running towards the source of the sounds, making noises every step he takes on the beautiful green grass.

…

"Alright, I know every one of you are worried, so that's why I will send Sonic to gather any data about Robotnik's new weapon." Sally looks at Sonic, "Sonic, can you handle this?"

Sonic responded by giving her a thumbs up and smirk "You can count on me, Sal! We will defeat Robotnik once and for all!" The enthusiasm within him inspired the Knothole Freedom Fighter members, who cheered on like as if this was going to be the final battle to end the Robotnik's tyranny once and for all.

"Alright, Sonic, you will go… Now!"

Sonic saluted before hastily leaving the village through the Great Woods. The blue hedgehog rush through the woods, avoiding trees and other obstacles on his way. He finally made it out of the woods in under 10 seconds due to his sonic speed that no living thing could see with their naked eyes.

Upon exiting out of the woods he stops in a ledge of a hill that he was standing on. His eyes spotted the depressing Robotropolis. Smoke from robot factories filled the sky above it, blocking out the sunlight from casting light upon the once beautiful city.

Sonic remembers when he was just a kid when Mobotropolis was still beautiful. Those thoughts made him feel a little sad inside, thinking about that replaced the city. Sonic looks below the hill. It wasn't that steep so he decided to hop out of the hill and rolled down like a ball of blue.

Sonic finally reached the bottom and unrolled, glaring at the darkened buildings with repulsion before dashing inside without being spotted.

…

The noises sounded closer and closer but the woods were getting denser and denser to the point of darkness. "Jesus Christ, even the forests in Soviet Russia weren't this dense." His red fur softly brushed against the leaves, bushes and trees until they were making rough contact every second inside the thick woods.

However, a small beam of light peaked through a hole in a tall bush. His idea that he was next to civilization was when the voices were clearer than it was before. The dog puts his hands through the hole before widened it and poking his head through it.

The first thing or two things in fact he saw was a male little yellow fox talking to a female chipmunk that was a little taller than the fox. "I hope Sonic will be okay." Said the little fox, which the dog assumed was a little kid because of his voice.

"He will, Tails, he has led us to this point. The Freedom Fighters will defeat Dr. Robotnik and we will finally end this war." Reassured the chipmunk, placing her hand on the worried fox's right shoulder.

The red-furred dog leaned forward to hear this conversation. However, this led him to accidentally fall out of his spot, making a loud thud and landing face first on dirt upon impact. The slowly looked, his face having bits of dirt on some parts of it, and saw the two fox and squirrel looking at him with puzzled expressions on their faces.

"Who are you?" asked the little fox.

"Are you with Robotnik?! What are your intentions coming here to Knothole?" also asked the chipmunk

The dog wiped off the dirt off his face before responding with a single word, "Who?!"

The little fox turns towards the squirrel "Sally, why will a Mobian ever side with Robotnik?"

The chipmunk called Sally thought about it for a second until she responded "You have a good point there, Tails." She then looks at the dog and put his hand in front of him. "Sorry about that, we haven't seen anyone new here for a longtime."

The dog grabbed her hand before being picked up. "No worries, I will be in your position if someone came out of woods unannounced. Also, my name is Favian Hoffman if you were wondering. Also, what's a Mobian?"

Sally and Tails looked at each other dumbfounded before looking back at Favian. "What? Is it something that I said?"

Sally shook her head "Well, we're surprised that you don't what a Mobian is. Me and Tails are Mobians actually. Aren't you a Mobian?"

"Hmm, no? You guys are like the many Anthropomorphic from where I'm from."

"I see. Maybe… you're not from around here?" suggested Sally.

"Could be, I found this blue emerald in front of my lawn and got teleported here. I think I got transported to your world. Uhhh… what is it called?"

"Mobius." Responded Sally.

"Thank you. Anyway, what are your names?"

Sally responded "My name is Sally Acorn, leader of the Knothole Freedom Fighters. I lead this group to fight against Dr. Ivo Robotnik and liberate Mobotropolis from his tyranny."

"And my name is Miles Tails. I can hover with my two tails, hence my name."

Favian was intrigued by this. "Hmm, prove it."

"Okay!" Tails proceeded to turn around, facing away the two before started making his two tails started to twirl in synchronization. The tails started gaining speed until it was a circular yellow blurriness. Next, Tails proceeded to get lifted up in the air by his tails until he was hovering up in the air.

Favian found this impressive as he has never seen anyone from his world have this ability. "Impressive, if I do say so myself."

Sally then remembered something that Favian said. "Hey, Favian, didn't you say that you have an emerald?"

"Yes. Why?"

"Does it by any chance glow?"

"Yes."

Sally gasped. "I think you have a Chaos Emerald!"

"A Chaos Emerald?"

"Legend tells that there are seven Chaos Emeralds hidden in Mobius. Once someone gets all of them they unlock its true power. Can I see it?"

Favian complies by pulling out the blue emerald, which glowed slightly bright but not eye-blinding bright.

"You do have it! I can't believe it! I thought the Chaos Emeralds were just a myth. It seems that I stand corrected. Mind if I inspect it?"

"Nah, have it." Favian tosses it to Sally, who catches it. "Nice catch." He complimented. But Sally was distracted to hear the compliment because she was busy inspecting the Chaos Emerald. She proceeded to pull out a handheld with a screen in the middle. "Nicole, scan the item."

"Scanning…" responded the handheld, sounding like a robotic female. "Scanning completed."

Sally looks at the screen which displayed the many data on the screen. "Thank You, Nicole." Sally then looked at Favian "Follow me, you must be hungry and thirsty from all of that walking."

"Well, I only ate breakfast this morning, so yeah."

"Can I come?" asked Tails.

"Sure." Responded Sally, which made Tails excited.

The trio started walking, heading to a hut made out of wood.

…

After making his way inside Robotnik's HQ, Sonic explored the area. He heard some footstep coming from the next hallway. Sonic looks up to see an opened vent on the ceiling, so he jumped up, grabbed the vent and pulled himself in.

The footsteps got closer and closer until he saw two SWATbots passing by without noticing the blue hedgehog. "Can't walk around the hallways. To many SWATbots." He decided to crawl through the vents instead.

He slowly crawled to avoid making thuds every time he moved. After a while of walking around he heard distant voice that almost sounded familiar. He continued crawling through the dirty vents, having gotten his knees and elbows dirty, until he saw a bar where the familiar voice was coming from. Light penetrated through the exposed bars.

Sonic crawled next to the bar to see who was in there. It was Dr. Ivo Robotnik with the doctor's nephew, Snively, next to him. "Finally, after weeks of hard work, the Doomsday Project is finally complete!" exclaimed the mad doctor.

"Sorry for my ignorance, sir, but what does it do?" asked Snively, which angered Robotnik due to not liking explaining himself.

"Fool! The Doomsday Project is what will lead me to conquer the Freedom Fighters and Mobius! The tower will deploy pods that will land everywhere on this planet. The pods will deploy devastating energy that will finally eradicate those pesky Mobians once and for all! We just need to wait twenty-four hours for the pods to be ready."

"Oh, very good, sir!" responded Snively.

Sonic glared at the duo from the vents "Not in my watch." He muttered before heading back out of the base via the dirty vents.

…

Favian Hoffmann gulped down his food mixed with water. The dog slightly moans in delight. "Hmm, this is really good. You guys gotta have an amazing chef if the food is this amazing!" he complimented, continuing eating his food, which was meat with mashed potato mixed with sauce.

"You can thank Antoine for the cooking. He's the best cook in this village." Stated Sally, proceeding to stab her spaghetti, rolling it before munching it.

"I really want to praise Antoine in person, but I don't want to interrupt him when he's cooking."

Sally proceeded to gulp down her spaghetti before thinking about something. "Sooo, Favian, tell me about yourself."

Favian wipes his mouth with a napkin before responding, "Well, I'm good in using weapons. I fought in the army when I was younger."

"Really? What army?" asked Tails, intrigued by the topic.

"Well," Favian proceeded to put his hand in his left pocket, grabbed something and gently pulled it out. It was his Iron Cross that he was awarded for his deeds in Berlin. "I fought in U.S army back then in a small squad. My squad fought in many important and unimportant battles-"

"Wait, what are Germans and the U.S?"

"Well, basically, Germans are an ethnic group and the U.S is a country that is very well known for being democratic and allowing freedom for everyone of any race, culture and ethnicity."

The duo was surprised by this explanation. "So, they're like us?" asked Sally, eyebrow raised.

"What do you mean?"

"We operate this resistance group called the "Knothole Freedom Fighters." We fight against the tyrant known as Dr. Ivo Robonik." Responded Sally

"Well, his name doesn't sound that bad…"

"Don't let that fool you. Dr. Robotnik is considered the worst thing to have come to this planet. He turns animals into mindless robots under his command, he destroyed the once beautiful city of Mobotropolis, my birthplace, and turned it into his own twisted image that he calls a "city". We have been fighting him for years' now and to make things worse, he has created a machine that we don't know how it works! I just hope we finally defeat him once and for all."

Favian was shocked by this mouthful of an explanation. "Wow. I feel sorry for you guys. Spending so many years on fighting a tyrant to liberate your city. I know how that feels."

"Really?" asked Sally

"Yes… Berlin… I fought in Berlin for months. The things I witnessed. Those poor children." Tears appeared on his eyes before they slowly rolled down his cheeks. "They rounded up multiple civilians of the city and shot them, burned them and took them back to Russia to do things that not even the toughest soldiers could bear witness." The dog puts his palm on his head. "Just talking about it makes me sick in the stomach. I think I lost my appetite." he proceeded to use the napkin to wipe his tears.

Sally Acorn and Tails felt sorry for Favian for what he had experience. "I-I'm sorry, Favian. We didn't know."

"No, no. Don't blame yourself. That was all in the past now. I'm just glad my squad liberated the city and its country. So, at the end of the day, everyone in my world are now safe." Favian had a small smile on his face to express that he's okay.

"Well, since you said that you fought in a war, I ask you to join us-" Sally's was interrupted when the door for the place was burst opened by something. A blue blur whizzed past Favian, causing his ears and fur to blow forward.

The blue blur stopped next to Sally, revealing to be Sonic. "Sal! I got some news about Robbutnik's new machine, and it isn't a good one." Stated the hedgehog.

"Really? What do you have?" asked the squirrel.

"Robotnik is going to use a tower that will unleash pods all over Mobius that will release dangerous energy that could exterminate us and everyone!" told Sonic

Sally's face changed to complete worriedness. Could Robotnik actually beat her and her friends in this war that has been going on for so many years now. Sally stood up from her chair staring at the space within the hut before speaking. "Call everyone to the bonfire area. We need to discuss this issue."
