Hey guys! It is to my knowledge that Sonic has a brother, he is Tails, but not blood related, more of a taking in sort of thing. So I'm sticking by that! I'm going to be making the chapters a little lengthier (About 5,000 words, including chapter name, and author notes) so I can get a bit more in each chapter, but the chapters will be the same amount. The reason I'm telling you this is so you don't worry about the updates taking forever. Trust me I am not going to abandon this story!

Chapter 1: Turning Point (Meeting Others)

Twilight and Fluttershy looked at the creature before them, while it resembled a rabbit, it seemed to be a moving decaying corpse. The "rabbit" had large claws on the end of its paws, while it had grown razor sharp fangs, its eyes had taken on a reptilian appearance, and finally it was literally falling apart. "Gizmo, how did you find this creature?" Twilight asked, looking at the tan earth pony, he moved his curly blonde mane out of his emerald green eyes and smiled. "I was testing out a new invention. A cage that you can hide under leaves or dirt, and it has this pressure plate. When something steps on it… BAM! The cage traps it! I was going to let the little guy go until I saw him like this." He explained motioning towards the cage with his hoof.

"He seems to not be in any pain, but those fangs are producing some form of toxin, not deadly, but who knows what could happen." Twilight muttered, while quickly scribbling down some notes. She looked at the rabbit and sighed. "We can't do much about it right now, we'd need someone with extreme intelligence! Someone who can really be of use! We need…!" She had begun but a loud crash outside the library broke her away from her sentence. Sonic looked up from his book, and got onto his feet. "I'll check it out." He said, which let Twilight get a good look at his arm. She saw the red bite marks and stopped him. "Sonic, what is that?" She asked, he tensed up and said "A bite mark…" "How did you get it?" She asked narrowing her eyes. "I may or may not have been taking a late night run through the Everfree forest…" Sonic replied, waiting for her to shout. "Just be more careful next time." She said with a sigh.

Sonic walked outside and began looking for what might have caused the sound, when he heard an all too familiar voice. "HELP! I'M STUCK!" Sonic scanned the area searching for the source of the muffled voice. He saw someone with their head stuck in the ground. He smiled and began to dig out the yellow fox. "Tails! How did you get here?" Sonic asked, once he had gotten out of the hole. "Sonic? Wait… Does this mean…? I'm in…?" Tails had begun to sound worried. "Hey calm down! The ponies here are friendly, you don't need to worry." Sonic said, making his brother let out a sigh of relief. "So, how have things been back in Station Square?" Sonic asked, while they walked back towards the library. "Things have been peaceful, a little too peaceful, you know?" Tails replied. They entered the library and Fluttershy let out a startled shriek.

"Fluttershy! Are you ok?" Gizmo asked, helping her onto her hooves. "Yes… I just wasn't expecting Sonic to bring anyone back." She replied, attempting to catch her breath. "Sonic, who is this?" Twilight asked, looking at the yellow fox with two tails. Sonic smiled and replied "This? He's my little brother! Twilight I'd like for you to meet Tails." Sonic said, pushing the yellow fox forward. "You're Tails? Sonic's told us so much about you!" Twilight happily chattered. "You must be Twilight. Sonic's girlfriend right?" Tails asked. "A lot more now buddy, we're parents." Sonic replied. "You are!? Well I guess it has been years since we'd last spoken." Tails replied, rubbing the back of his head. "Well, we could use your help. We've got this animal, and we aren't sure of why it's in this condition…" Twilight began to explain, but Tails nodded and began to inspect the creature. He revealed a syringe and stuck it into the animals hide, extracting a small amount of blood.

He pulled out a device about as big as his hand and inserted the needle into one end. After a few seconds it began to dispense a long strip of paper. He pulled it out straight and began to read what it said. "Genus Sylvilagus, or commonly known as a Cottontail Rabbit. Subject seems to have gone through heavy mutation… Cause is undeterminable…" He spoke out the words carefully and calmly. "A cottontail rabbit?" Fluttershy asked, looking the cage. It growled at her before letting out a loud screech. "Whoa! Sounds like the little guy is seriously pissed off!" Gizmo said, staring at the small animal. Fluttershy looked at the rabbit and began to move closer to him. "I'm sure all he needs is a little love and affec… OW!" Fluttershy shouted, the rabbit had its teeth embedded in her flesh, she stared as the rabbit refused to let go. Sonic grabbed a book and began to beat the small animal on the head, until it let go.

Fluttershy looked at the bleeding bite mark, and Sonic gasped. He moved his arm close to her leg, his scars matched the fresh bite exactly. "Oh… My… God…" Sonic muttered looking up. Twilight was shocked, this thing had bitten Sonic as well. "So it's bitten you too?" Gizmo asked, before asking "How many more has it bitten?" Twilight began to speak quickly and rapidly "We have to find out if anypony else has been bitten. We'll split up, Sonic and Fluttershy… You two stay here… I'll go get Speedy and Spike." Sonic nodded, while Twilight rushed upstairs.

Sonic, Fluttershy, Derpy, Silver, Scourge, Trixie, and Applebloom, were escorted into a hidden location, personally by Princesses Luna, Celestia and Cadence. They entered the stone building, heavily guarded, with a medical staff on standby to record and results. "We're sorry, but until we can determine the effects of this creature's poison, you all must remain here. Once we have it all sorted out, we will release you." Celestia said with a frown. "We understand Princess. It's for the greater good." Sonic replied. "Sonic, I'm trusting you keep them all under control." She added, Sonic replied with a nod and the three Princesses left.

"Well this is just great isn't it?" Scourge asked. "We get bitten by a rabbit and we're locked up like some kind of monster?" Scourge finished while Sonic let out an annoyed sigh. He led the others to a large room with several beds, before sitting on one. "Might as well get comfortable…" Sonic muttered. He heard someone groan in pain, looking over it was Fluttershy, she had one leg over her stomach, and her face was frozen in pure agony. She fell over, and Sonic jumped up. "Fluttershy! Are you ok?" He asked, forcing open one of her eyes, it was beginning to shake, he saw her pupils change shape, moving to a lizard like slit. She groaned as her teeth began to grow creating four large fangs that prevented her from closing her mouth. Sonic had a tight hold on her face, as a result a chunk of flesh was accidentally ripped away with ease. Fluttershy let out a hiss that sounded like it came straight from a sci-fi movie. She lunged at him sinking her teeth into his neck, injecting more of the poison into his veins. He attempted to force her off, but found he couldn't.

Scourge grabbed her by the neck and yanked her off, he put her in a head lock, she struggled for breath against his grip, but eventually she went limp. "Scourge! Did you kill her?" Silver asked, running forward. "No, I cut off oxygen until she passed out." Scourge replied, as doctors and scientists rushed into the room, and began bandaging Sonic's neck. Several guards lifted the unconscious Fluttershy and took out of the room, leaving everyone there in silence. "Will that happen to us?" Applebloom asked, she was obviously frightened and she had a reason to be so. "I think it will." Silver replied before the group fell into an eerie silence.

---

Sonic sat in the room, he was alone. All the others had turned, Scourge, Silver, Trixie, Derpy, and even sweet little Applebloom. He knew he would be next, it's only logical, but nothing could save him from his fate.

Sonic sat with his knees against his chest, his arms resting on them, he stared straight ahead of him. He was crying but his tears had dried up hours ago. He felt a sharp pain in his chest, he knew that it would happen soon so he was prepared, but he would never be prepared for the result. The pain intensified, making him yell in pure agony, he began to grab at his chest, until he felt the change begin. He noticed the large mirror next to him and saw the horrors unfold. His gloves began to tear, revealing bone from the decaying flesh. He saw his teeth grow, when he tried to close his mouth the four fangs hit each other, making it impossible. He finally saw his eyes begin to change, which would be the last sign. There was a wet smacking sound as chunk of his skin and muscle hit the stone floors. He grabbed at his face, his left eye fell out of its socket. Sonic let out a loud roar, a signal that the transformation was complete. He felt strange like he couldn't think properly. Several armed guards entered the room, and Sonic charged at the nearest one.

He bit down on one guard, who let out a cry of pain, while the others attempted to free him from Sonic's grip. He let out a loud hiss and jumped from guard to guard until they were all bitten. He managed to avoid them and rushed into the facility, scaring scientists and doctors as he ran past. He began to slam all of his body weight into a metal door, and eventually broke it down. He saw the others, all trapped inside strange cylinders filled with a blue liquid. "Subject S-1 has escaped! Requesting immediate lock down!" A scientist shouted. Sonic approached him slowly, taking time with each step. The pony backed up until he hit one of the tubes, knocking it over, creating a domino effect. The tubes shattered releasing the others, who turned to face the scientist. "No! No! NOOOOOOOOOOOOOOOO...!" Sonic turned to face his infected brethren, each one had begun to decay, chunks of flesh having been removed. They ran out the room, leaving the scientist, who was gasping for breath. "GODDAMMIT! I PISSED MY FUCKING PANTS!" He shouted, after a few moments.

The seven of them ran down the halls attacking anything in their path, guards, scientists, and doctors. They were heading towards the main point of research, where they were attempting to develop a cure. Guards were falling left and right, but the room had many guards inside. "Don't kill them! We have to capture them!" A scientist shouted. "Why? Those things are monsters!" A guard asked. "One of those 'Monsters' is royalty!" The scientist replied. Sonic led Silver and Fluttershy down a left hall, while Scourge led Derpy, Trixie, and Applebloom down the right. Both doors would be vulnerable, but the left was quickly shut, preventing any form of entrance. "One two three... AH! THEY'VE SPLIT UP!" A guard shouted rushing to the other door. Scourge was approaching his door, and the guard was just as close, but the guard managed to shut the door, preventing Scourge from entering. "Mother fuckers, they've drilled us in here!" The guard shouted leaning on the door.

"You need to calm down!" "How can I? We have a fucking zombie apocalypse going on!" Sonic watched the guards argue, he began to slam into the door, while the others did the same. The doors began to dent from the onslaught, but they did not break. Sonic began to wonder how they would get in, after all a cure could not be created. His mind was clearing he was starting to regain some of his senses as the poison finally settled. Sonic grabbed onto the handle of the door and stumbled in, almost in a drunk like fashion. He looked up at the guards and asked "What? You never seen a hedgehog before?" The guards rushed forward while the others began to come around as well. "What… Happened…?" Sonic asked, while a guard moved over to assist him. When the guard was in range, Sonic bit down on his neck, injecting the poison in him. "You really should have just killed us…" Sonic muttered before leaping forward with his fangs ready.

---

Sonic watched as the guards and scientists slowly turned one by one, until the entire facility was under their control. "They will be in an animal like state, at least for a few minutes… After all we came through didn't we?" Sonic asked, looking at the others. "So strange… Being alive and dead… At the same time…" Scourge muttered. Sonic laughed and said "You think we're dead? Not at all, this is simply a virus… Planned to spread… After all this virus has some advantages doesn't it?" Sonic asked. They nodded while Sonic let out a laugh. "I mean this is amazing… New powers we had never had." Silver said, pulling a spear out of his torso. "This must be spread, it must be shared with all life! It must be known throughout all of Equestria!" Sonic shouted, watching the newly infected rise. A single non infected pony rose up, he had been unconscious and saw Sonic standing over him. "You are lucky." Sonic said with a smile. "What do you mean?" The pony asked, backing slowly away from the blue hedgehog. "You are the only one who will not become one of us. If you do me one favor… Run… Run to your little Princesses and tell them the Infected come!" Sonic shouted, while the pony got onto his hooves and bolted in the opposite direction.

Tails looked at the rabbit, it had begun to act like a rabbit again, but only when it was hungry or thirsty. Otherwise he wasn't able to approach it, making research difficult. "Uncle Tails?" Speedy asked, getting the fox's attention. Tails looked at his niece and smiled. "What can I do for you?" Tails asked, while Speedy nervously tapped her hooves on the ground. "Mom wanted me to tell you that lunch is ready." She said, not depressed, but not happy, more emotionless, like a robot. Tails frowned as Speedy walked away. "It's gotta be hard on her, not to mention Twilight, and then there's Rarity… Not to mention Applejack…" Tails muttered, he cleaned of his tools and moved into the kitchen, where Twilight and Spike had made lunch. "Thanks Twilight. Thanks Spike." Tail said sitting at a table, he then began to nibble at a sandwich while writing down some notes.

"You know Tails, you should really take a break. See some of your other friends. I'm sure they'd be glad to know you're here." Spike said, watching Tails scribble on the notepad. "Spike is right, you need a bit of fresh air. I'll take you around town." Twilight offered, but Tails didn't reply, he continued to write. Spike walked past and stepped on something, making a loud crack ring through the tree. Tails looked and saw he had snapped the thick metal of a syringe, it had been standing point up. "Sorry Tails! I didn't see that there!" Spike said picking up the metal. "Why didn't that hurt you?" Tails asked looking at Spike curiously. "I'm a dragon! I've got tough scales! Lava doesn't even hurt me!" Spike boasted crossing his arms in a triumphant matter. Tails shot up and shouted "OF COURSE!" He ran into a different room and returned with an unknown tool. "Spike, would you mind if I took a few scales? For scientific research?" Tails asked, Spike nodded slowly and moved over to Tails who moved the tool towards him. Spike let out a quick yelp of pain when the tool plucked a few scales from Spike's hide.

Tails held one out at the rabbit who instantly attacked, the rabbit bit the scale in half and growled. Tails began backing up, while saying "So much for that idea." Twilight looked at him and said "Don't get so down on yourself, we're making progress aren't we?" Tails smiled before moving back into the kitchen and continuing to nibble at the sandwich. "So would you like for me to show you around town?" Twilight asked, Tails looked up and replied "Sure, I guess a break is needed. It just can't be too long, we need to get as much work done as possible."

Tails looked at the small and colorful town, he felt happy, just being in this place made him feel so. This would be the first he met Twilight's friends. She'd told him about them, but he never got a chance to meet them, it would also mean that his friends would see him for the first time in years. While excited he was also very nervous, would his friends freak out at him being here? No… Would they…? No... After all they were his friends, they would never do that. "First, we'll visit Sugar Cube Corner! The best place to get a tasty treat." Twilight explained, she led Tails inside and he saw the arrangement of sweets. Cakes, pies, muffins, but the most impressive looking were the cupcakes. Several different types, different colors, different flavors. Tails couldn't remember the last time he'd seen so many deserts. "Twilight!" A voice happily shouted, Twilight was tackled by Pinkie who was covered in flour and sugar. "Hi Pinkie Pie…" Twilight said between breaths. Pinkie got up, allowing Twilight to breathe freely. She turned to face Tails and said "Pinkie, I'd like to introduce you to Tails. He's Sonic's younger brother." Twilight explained, while Pinkie went wide-eyed at Tails. "He's so adorable!" She shouted before tackling him and shouting "Who's a little adorable fox? Who is? Who is? You are!" She was rubbing Tails like a dog, while he struggled against her.

"Twilight! Help!" Tails shouted, suddenly Pinkie was floating in the air, still making the rubbing motion, until she noticed she was off of him. Tails was still lying on the ground taking deep and heavy breaths. "Are you all right?" Twilight asked, while Tails grabbed onto the edge of a table and slowly rose. "Fine… I was just… Tackled by… A pink horse… Nothing to bad…" Tails muttered as Twilight set Pinkie down. "Pinkie, please try to control yourself. He's a guest, not a pet." Twilight said rubbing her forehead. "I'm sorry, he's just so adorable!" Pinkie shouted, while Tails braced to be tackled again. It never came so he opened his eyes, seeing Pinkie staring at him. "We just popped in to say hello, I'm showing him around town." Twilight explained before the decided to move on. "We can see Applejack next if you'd like." Twilight suggested. Tails nodded before they moved on to the farm that the Apple family called home. Tails tripped and landed in mud, covering the fox from head to toe. An apple flew over Tails' head, nearly hitting him, but he had ducked at the last second. "Almost! Don't worry Twilight! I'll save you from that monster!" Rainbow Dash shouted flying straight at Tails, he thought quickly and jumped into the air, spinning his two tails in the air like a propeller he managed to fly over Rainbow Dash, which distracted the mare causing her to crash into the side of a building. She recovered and launched herself at him, but Tails flew higher than her and landed on her back.

"What the!? Hey! Get off me!" Rainbow Dash shouted, while Tails held her wings down, forcing the two to plummet toward the ground. Before the moment of impact Tails, began to spin his tails, allowing them to make an almost smooth landing. Rainbow Dash fell into the dirt, making a small dust cloud, but she wasn't hurt, at least not seriously. "Rainbow Dash! Are you ok?" Twilight asked running over to her friend. Tails got off and began wiping the mud off his fur. "TAILS! What was that!?" Twilight asked him. "I was acting in self-defense. She attacked me first." Tails explained, rubbing the last of the mud of his fur onto the ground. "Sorry if I hurt you. I just tried to defend myself." Tails said walking back to Rainbow Dash who stared at him with shock. "Rainbow Dash I'd like for you to meet Tails. Sonic's younger brother." Twilight said, while Tails helped Rainbow Dash up. "Hi… How did you do that…?" Rainbow Dash asked.

"It's something I've always been able to do… I actually used to get made fun of it… Then I met Sonic! He took me on as his sidekick, and I learned not to care what other people think of me, as long as I have my friends!" Tails answered, turning to show his namesakes. Applejack had come out to see what the commotion was and saw Tails standing there with Twilight and Rainbow Dash. "Howdy Twilight. Yah need somethin'?" Applejack asked, walking over. Twilight smiled and replied "I'm just showing my brother in law around. He needs a break from his work." "Brother in law? You remarry already? You know they're workin' on a cure right?" Applejack questioned. "No! I don't think you understand! I'm Sonic's brother, you must be Applejack. Twilight's told me about you." Tails said, trying to fix the situation.

"So you're Tails? Sonic sure talked high an' mighty 'bout you." Applejack said with smile. "He did? What did he say?" Tails asked, now curious as to what Sonic had said. "He said you saved an entire city on your own. Even beat that Eggman guy!" Rainbow Dash shouted. "He had said you're his best friend. He can trust you through anything." Twilight added. "He said you never gave up on 'em. Always by his side no matter what." Applejack finished, leaving Tails feeling shocked. "He said all that? He didn't mention any of the times I screwed things up?" Tails asked. "Nope, but yah don't need to worry none. Everypony makes mistakes. It's all a part of life." Applejack said, turning and moving back inside the house. "Well, next we should see Rarity. I hope she's not too busy." Twilight muttered leading Tails back towards town.

"Oh, I must say you are simply the cutest thing I've ever seen! You're a like a little kitty! So fuzzy and adorable!" Rarity shouted, she was brushing out Tails' fur, it had become a mess and he hadn't combed it out in a few days. "OW!" Tails shouted feeling the brush hit a knot in his fur. "Sorry! Just need to do this quickly and…" Rarity had started, before quickly bringing the brush through the knot, ripping it off of Tails. "Oh! I'm sorry dear! Perhaps we should stop…" Rarity suggested while Tails stood up. "Thank you for at least attempting Rarity. I really appreciate the offer." Tails said rubbing the spot on his head where the patch of fur had been ripped out. "So you're Sonic's brother? Does Knuckles know you're here?" Rarity questioned, leaving Tails nervous. "No, he doesn't Twilight went to tell him, and I'm just waiting for her to come back." Tails explained, at that moment the door opened, and Twilight walked in.

"Well, Knuckles didn't believe me. He had to Gamma and Metal Sonic with something…" Twilight said, making Tails gasp. "Metal Sonic? What's he doing here?" Tails asked starting to look angry. "Gamma managed to reprogram him, so he's friendly now." Twilight responded, starting to lead Tails to where Knuckles was going to meet Gamma. He had been led to the outside of Applejack's barn, Tails could hear voices inside.

"Hand me wrench." Metal Sonic ordered, holding out a hand. Knuckles scanned the various tools and asked "Which one is that?" Metal Sonic let out an annoyed groan and asked "You don't work with tools much do you?" Knuckles shook his head and replied "Never had a need to. When you spend most of your time on a floating island, you don't really need tools… At least not beyond these." Knuckles lifted his fists into the air. "I would use a screw instead of a bolt there, it would hold together better." Tails said opening the door. "Tails?" Knuckles asked shocked. Knuckles grabbed the fox in a hug and shouted "Man! It feels good to see you again!" Then as if he had just realized what he was doing he dropped Tails and said "It's great to see you again." Metal Sonic looked up at him and said "Finally someone who know what they're doing. Tails hand me that wrench." He pointed a metal finger at a wrench sitting on a wooden crate.

Tails handed him the wrench and said "Look, I know you've supposedly changed, but don't think I'm just going to forgive you for everything you've done to us right away." Metal Sonic sighed and said "You may be his brother, but you are Sonic's polar opposite. Willing to trust without a second thought, reckless, hates sitting still. Then there is you. Very untrusting, you think too much, and you remain stationary for long periods of time." Tails wasn't sure if this was a compliment or an insult so he didn't reply instead he asked a question. "What are you working on?"

Metal Sonic looked up and replied "We're fixing up Omega, Shadow fucked him up pretty bad. I'm sure you've been told about the second invasion. Well Shadow was helping them, until Eggman tried to take over. Shadow worked together with Princess Luna and defeated the old quack. He banished himself. Making sure he wouldn't harm another soul. Amazing isn't it?" Tails was confused, what about any of this was amazing. "I… I'm not sure what you mean…" Tails said nervously. "The fact that this invasion happened only a month ago. This town had been burned to the ground, now look, almost identical. Same thing with other towns. Even Canterlot, amazing how fast this whole place was fixed up." Metal Sonic said while working on Omega. "Knuckles, go get Gamma. He should be here." Metal Sonic instructed. Knuckles nodded and left the barn to search for the robot.

"Listen… Tails… I know about my past… I know how miserable I've made your lives… I hope to make up for that. Whether you trust me or not is not anything I care about. I just want to make it up…" Metal Sonic said, twisting the last bolt in place. The barn doors opened, allowing Gamma and Knuckles to enter. Metal Sonic nodded as Gamma placed a small motor into Omega's chest, activating the robot. Omega's eyes began to glow with red lights, and he looked around the room. "Where… Am… I…?" Omega asked. "You're in a safe place." Tails replied, helping Omega onto his feet. "Tails? It has been long." "It has Omega… It has…"

Celestia stood on the balcony, a guard approached and began to speak. "Princess… I have troubling news… Sonic, he has turned… He led the others… They've infected everypony in the research facility… He has a message for us…" The guard spoke, his voice shook with fear. "And…?" Celestia asked, waiting for the guard to speak. "He says… The Infected come."

There you go! Chapter 1 is complete! If you read the note above then you'll know that each chapter will now be around 5,000 words, but that includes the chapter title, and author's notes like these! I will be using OCs from the previous story. They will not appear until later chapter however. I will admit, that this will take longer to update, seeing as how I take my weekends off from writing. I will try to get enough to purchase Microsoft Word on my other computer so I can write on weekends. I'm going to try and take things more seriously because as I had mentioned in the last story (At what point I do not remember) I said I was going to be making a Wind Waker crossover, well there has been a change of plans… It will be taking a boss from that game, and he will find his way into Equestria… How will it be? You'll have to read and find out! I guess that's all for now, remember to leave a review telling me what you liked and what you didn't like. Yeah, that's about it so bye!
