AUTHOR'S NOTE: Okay, this is my first crossover and I think I actually did a nice job of it. So, nothing much else to say so, read and enjoy! Oh, wait! Timeline! This takes place after Age of Steel for The Doctor and Rose and sometime in Sonic's untold future.


Rose Tyler was holding on to the TARDIS console as the time-ship rattled and jerked under the control of its somewhat mad pilot. She watched as the tall, thin man who looked like he was in his early thirties pressed buttons, flipped switches, and pulled levers. He was wearing a brown, pinstripe suit and white, high-top converse sneakers. Rose heard the metallic whooshing sound that the ship made during flight. She loved that sound.

"Where are we going now?" she asked the tall man.

"I don't know!" he said gleefully. "I set the destination to random. All I know for sure is it's a planet with life on it. After that, who knows?"

"Cool!" said Rose excitedly.

"Yeah!" replied the man excitedly. He ran to the other side of the console and pressed a couple more buttons. The TARDIS settled down slightly and then came to a complete stop.

"So where are we, Doctor?" asked Rose, looking at the screen on the console and trying to decipher the strange, Gallifreyan symbols that it displayed.

"Let's find out," said The Doctor, ignoring the screen, grabbing his long trench coat off the coral pillar, and heading for the door. He opened it and gestured to Rose to follow. "C'mon! Let's not spoil the surprise. Where's the fun in that?"

"Alright," said Rose with a smile as she followed The Doctor out the door. She stepped out of the TARDIS and onto the ground outside. It was sidewalk. She looked around and saw people walking around. There were skyscrapers and buildings. It looked like a regular city.

"Are we on Earth?" asked Rose. "Seriously? You put the setting on 'random' and the TARDIS brings us to Earth again? What are the odds of that?" The Doctor pulled a small, metal tool with a blue light out of the pocket inside his coat and pressed a button on it. It made a metallic buzzing noise and he waved it back and forth in front of himself.

"Sonic screwdriver says 'no'," said The Doctor as he put the tool away. "Not the same kind of atmosphere."

"Are we safe then?" asked Rose in concern.

"Oh, yeah," said The Doctor. "But it definitely tells us it's not Earth." Suddenly, out of nowhere, a fox-like biped jumped down in front of them and ran down the sidewalk.

"Excuse me! Sorry!" he yelled as he ran away from them.

"So does that," said The Doctor. "That's not of any Earth origin."

"Well, we saw talking, humanoid cats on New Earth," said Rose.

"Yeah, but that definitely wasn't a cat," said The Doctor.

"So you're saying that the only humanoid-animal life forms on New Earth were cats?" asked Rose.

"That's exactly what I'm saying," said The Doctor. Rose looked across the street at what looked like a shop window. She saw a sign that read "50% OFF ALL PRODUCTS" in large letters.

"That signs in English, though," said Rose. "Oh, no, that's the translation thingy from the TARDIS, isn't it?"

"Normally, I'd say yes," said The Doctor with a sigh. "But not right now. That sign is in English."

"Really?" asked Rose. "How's that?"

"I don't know," said The Doctor. "Why don't we look around and see if there's anything else that's interesting to see." He took her by the hand and pulled her along with him down the sidewalk. She followed him eagerly down the street and they both disappeared around the corner.


Sonic woke up to the sun in his face. He opened his eyes and was blinded by the sunlight flooding his room through his window. He sat up in his bed, stretched his arms out above his head, and yawned. Then he collapsed back down on his back and looked up at the ceiling. He heard the front door of his apartment open and shut.

"SONIC!" yelled a familiar voice from the front door. "SONIC! You there?" The cobalt hedgehog got out of bed and put his shoes and gloves on.

"Yeah, one minute Tails!" yelled Sonic. He walked down the hallway outside his bedroom and out into the living room of his apartment. He saw the two-tailed fox sitting on the couch in his living room.

"Hey there, Tails," he greeted the fox. "What's up?"

"Nothing, just thought I'd say 'hi'," said Tails happily. "Oh, who put that huge, blue phone-box thing in the alley by the building, because I was coming here through the alley and it was blocking the exit. I had to fly over it."

"I don't know," said Sonic with a shrug. "Never noticed it before."

"Really?" asked Tails.

"Nope, and I walked down the alley yesterday," said Sonic.

"Oh," said Tails. "Well, I hope they move it soon." He grabbed the TV remote and turned the TV on while Sonic grabbed a bowl and poured some cereal and milk in it. He ate the cereal and sat down next to Tails on the couch. They sat and watched TV for a while until they were interrupted by a news bulletin.

"Breaking news here," started the anchorwoman, who was a brown fox. "The Station Square Bank downtown has been held up. Police have not been able to confirm the perpetrator yet, but there have been witness reports of a black wolf who was acting suspicious in the building shortly before the silent alarm of the bank was triggered. Police report that the perpetrator is said to be armed and very dangerous."

"Sonic, a bank robbery," interrupted Tails. "Let's go stop a bank robbery."

"Okay," said Sonic. "Why not? I don't really have anything else to do right now."

"Cool!" said Tails as he ran to the door. Sonic followed and they headed towards the bank.


"So, what should we do first?" asked Rose excitedly.

"Well, I think that whatever we do is gonna cost money," said The Doctor. "So, I think we should go find a bank and get some of the local currency."

"Good idea," said Rose with a smile. They walked down the street a couple blocks before they came to a bank.

"Here we are," said The Doctor as they walked through the front doors.

"Why don't we just sonic the ATM machine outside the building?" asked Rose.

"Because we don't know if they're deadlocked," said The Doctor. "If we trigger an alarm, who knows what could happen. But we could be a lot more successful walking in and fooling a teller."

"Oh," replied Rose understandingly. "But how are we gonna fool the teller? We're gonna need a cover."

"I was just gonna look at a credit card so I can rig my psychic paper to act like one," said The Doctor. "I'm not gonna go stealing from people."

"What about the bank?" asked Rose.

"Okay, fine, I'm stealing from a bank. Happy now?" said The Doctor.

"Sure," said Rose with a smart smile. They walked up to an open teller.

"Hello, sir and ma'am," said the female teller with a friendly voice. She was a thin, black-furred squirrel with long, curly, black hair. "How can I help you?"

"I just wanted to know how I could open a credit card account," said The Doctor.

"Well, sir, you need to take one of these forms and fill them out at-," started the teller.

"Never mind that," said The Doctor as he held up his psychic paper. "I'm with the police doing an investigation. I need to look at your standard credit card. Do you have a blank one or something I could see?"

"Certainly," she said as she handed him a blank credit card. He took out his sonic screwdriver and scanned the magnetic strip. Then he took a good look at it and gave it back to her.

"Thank you, that will be all I need," said The Doctor as he pocketed his screwdriver. He turned around, took one look at the door, and turned back to the teller. He took out his screwdriver again. "Now, do you think you could get me a list of all the customers that have applied for a credit card of that kind in the last three months?"

"First I need to know why," she replied. The Doctor was about to reply when he was cut off by an angry voice behind him.

"Everybody put their hands in the air!" screamed the voice. The Doctor turned around and saw a black wolf holding a gun that was pointed at the ceiling. He fired off a couple rounds from the gun in his hand. The two security guards at the door pulled out their guns.

"Oh good, two on one," said Rose in relief. "Hopefully this will be over soon." The Doctor looked at them.

"No, they won't be helping us right now," said The Doctor. Then, as if on cue, the two security guards grabbed two people who were trying to run out the door.

"Oh no, they're with him?" asked Rose in an annoyed voice. The Doctor pointed his screwdriver at the gun of one of the guards and activated it. It buzzed for a moment before the gun exploded in the guard's hand and he dropped it. The gun was in pieces on the ground.

"Everyone on the ground!" shouted the wolf angrily, seeming to ignore the exploding gun. The Doctor pocketed the screwdriver and sat down next to Rose on the ground. A brown, female squirrel with short brown hair, wearing a blue vest with matching, shin-high, combat boots crawled over to them.

"What'd you do to that guard's gun?" asked the squirrel quietly.

"Nothing, what makes you think I did it?" asked The Doctor innocently.

"I'm not an idiot," said the squirrel. "I saw that tool thing you had. What is it?"

"It's a sonic screwdriver," said The Doctor. "I used it to ignite the round in the chamber to cause the gun to misfire."

"Sonic screwdriver?" asked the squirrel, trying to look as natural as possible as the armed wolf looked over everyone.

"Yeah," said The Doctor.

"Hey, stop talking!" barked the wolf as he aimed his gun at The Doctor. The Doctor stopped talking and the wolf turned to his partners. "Go empty out the safe. Make one of the tellers open it for you."

"No, stay there and drop your weapons," ordered a cocky voice from the entrance. Everyone's attention turned to the source of the order. There was a cobalt-furred animal standing in the door. A small fox kit stood next to him, smiling happily.

"Who's that?" Rose asked The Doctor.

"That's Sonic the Hedgehog and his friend Tails," said the squirrel quietly.

"Sonic the Hedgehog," said the wolf evilly. "You come to stop me?"

"Yeah," said Sonic with a confident smile. "Now why don't you make this easy for all of us and put the gun down?"

"No, you're gonna stand down," said the wolf. Then he bent down and grabbed the squirrel sitting next to Rose and held her in front of him with his gun to her head. "Or your precious princess gets it." The two guards turned to Sonic and Tails, one aiming his gun at Sonic, the other in a fighting stance, ready to take on Tails.

"Tails?" said the blue hedgehog.

"Ready," said the fox. Then, in a flash of blue and orange fur, the hedgehog took down the unarmed guard with a roundhouse kick and the fox did, what seemed to The Doctor, a tuck-and-roll in the air and flew at the armed guard at car speeds and blasted him into the wall behind him, landing on his feet and turning to face the wolf.

"Okay, change of plans," said the wolf. "You go get the money for me and the princess lives. Don't try anything funny. There's no other way to save her."

"No way," said the hedgehog with a shrug.

"You don't want to save her?" asked the wolf teasingly. Then, in a blur of brown fur, the squirrel grabbed the gun and the hand holding it, twisted hard, sending the gun to the floor, elbowed the wolf to the face, turned around and grabbed the wolf's head, kneed him in the stomach, and then kneed him again in the face. She let go of him and let him fall to the ground. She kicked the gun over to the hedgehog.

"Who says I need saving?" she asked rhetorically to the unconscious wolf in a mocking tone. "Sonic, get the police in here and have them clean it up. Tails, make sure these two don't leave." She pointed to The Doctor and Rose.

"Wait, why do we have to stay?" asked Rose in complaint.

"Because I wanna ask you two some questions and I don't want you running," said the squirrel. "And you two just smell like runners." She smiled and walked over to the blue hedgehog. The Doctor watched as the fox seemed to twist his tail around behind him and fly over to them, using his tail as an equivalent to a helicopter propeller. He landed in front of them and The Doctor noticed that he had two tails instead of just one.

"So, I guess that's why they call you 'Tails'," said The Doctor, pointing at the pair of tails behind the fox.

"Yeah," said Tails happily. He saluted casually to The Doctor and Rose. "Hello, there. As you have figured out, my name is Tails, and I am going to be your guard for right now. Try to run and I will not hesitate to drop you both before you can figure out what hit you."

"Okay then," said The Doctor casually. "We won't run. Now, if you don't mind me asking, how do you do that tail-helicopter thing?"

"I just twist my tails around in the air and they lift me up," said Tails with a smile.

"Really?" asked Rose in a surprised voice.

"How?" asked The Doctor disbelievingly. "How is that possible? That should not be remotely physically possible."

"I know, right?" said Tails, still smiling. "I've done the math, I've examined it on paper, I've said exactly the same thing, yet it works. I have no idea how. Makes absolutely no sense." The Doctor pulled out his screwdriver, leaned toward Tails, and started scanning the fox.

"Really?" he asked, amazed. He scanned Tails' head, his tails, and his chest before Tails interrupted him.

"What are you doing?" asked Tails cautiously.

"I'm scanning you," said The Doctor absentmindedly.

"For what?" asked Tails.

"Biological abnormalities that could cause that phenomenon of tail-induced flight," said The Doctor.

"What are you scanning me with?" asked Tails.

"My sonic screwdriver," said The Doctor.

"And did you find anything?" asked Tails, now wearing a face that clearly said that he thought the man was bonkers.

"No, and that's scaring me a bit," said The Doctor as he put the screwdriver away. Then he smiled gleefully. "That is spooky. Spooky in a good way, but spooky nonetheless. Have you been able to do that all your life?"

"It took a little practice, but yeah," said Tails. The Doctor stood up, dwarfing the fox in size now that he was at his full height. Rose stood up next to him. "So, who are you two?"

"Well, my name's The Doctor," said The Doctor with a smile. "And this is my friend Rose Tyler."

"The Doctor?" asked Tails confusedly.

"Yep," said The Doctor.

"People just call you 'The Doctor'," said Tails, still confused.

"Yep," replied The Doctor happily.

"Okay then," said Tails.

"So, Tails, what's your real name?" asked The Doctor.

"What's yours?" asked Tails.

"The Doctor," said The Doctor.

"What if I were to tell you that Tails is my real name?" asked Tails with a smart smile.

"I wouldn't believe you for a second," said The Doctor. Tails leaned his head on his shoulder and smiled sheepishly.

"My real name's Miles, but I like Tails," said Tails. "The only people who are allowed to call me 'Miles' are my parents."

"Ah," replied The Doctor.

"Yeah," said Tails. "So, you're not gonna tell me yours, are you?"

"Nope," said The Doctor.

"You're as bad as Sonic," said Tails with a laugh.

"What do you mean?" asked Rose.

"He won't tell anyone his real name," said Tails. "The only people who know are his parents and they won't tell either."

"Oh," said The Doctor with a nod. "And who is Sonic exactly?"

"Well, you're joking, right?" said Tails in a concerned voice. "You don't know who Sonic the Hedgehog is?"

"Not a clue," said The Doctor.

"They don't know who I am either, Tails," chimed in the squirrel as she walked up to them. "Which is why I want to question them."

"Right, you're the princess," said The Doctor.

"See? We know who you are," said Rose.

"Then what's my name?" asked the squirrel. The Doctor stared at her for a while he thought the question over.

"Alright, you got me," he said with a submissive sigh.

"So who are you?" asked the squirrel.

"First, what's your name?" asked Rose.

"Sally Acorn," said the squirrel. "Now, you answer my question."

"I'm The Doctor, this is Rose," The Doctor pointed to Rose.

"Doctor who?" asked Sally suspiciously.

"Just 'The Doctor'," said The Doctor.

"Just 'The Doctor'?" asked Sally with a cocked eyebrow.

"Yeah," said The Doctor.

"So, next question," said Sally. "Why don't you know who I am? Or Sonic, for that matter?"

"I'm an alien," said The Doctor. "I came here in my time-ship. I have no idea what planet I'm on. I travel around with my friend here. I came here with her for a leisure visit of your lovely planet and became the unfortunate victim of a bank robbery." Sally laughed slightly at this.

"Nice story," she said with a sassy smile. "Now, how 'bout a proper answer?"

"Well, I could give you a 'proper answer'," said The Doctor. He gestured air-quotes with his fingers when he said "proper answer". "But then I would be lying."

"Okay then," said Sally, smile faltering slightly.

"My turn now," said The Doctor. "Who's the blue... Hedgehog, wasn't it?"

"That's Sonic," said Tails. "I told you that. He's the hero of the planet, vigilante superhero, fastest thing alive, etcetera, etcetera."

"And the cockiest, most annoying, grand-standing, attention-seeking living thing you will ever meet," said Sally with another sassy smile. "Now it's my turn. What was that thing you blew up the guard's gun with?"

"My sonic screwdriver," said The Doctor.

"Let me see it," said Sally, holding out an open hand expectantly. The Doctor pulled it out of his coat and handed it to her.

"Tails," she said as she handed it to the fox. He looked it over, activated it and deactivated it a couple times, and slid the head up and down a few times.

"Definitely nothing I've ever seen before," said Tails with a shrug. She shot a surprised glance at him.

"That's because it's alien," said The Doctor as he extended his hand for the screwdriver. Tails handed it back to him.

"Okay, you two are coming with me," said Sally.

"Hold on a minute, it's my turn," said The Doctor.

"His turn for what?" asked the blue hedgehog as he walked over to them.

"My turn to ask a question," said The Doctor. "Now, exactly what planet are we on?"

"You're kidding, right?" said Sonic with a cocked eyebrow. "That's the question you choose? There are so many better questions. Like 'Who was that horrible bank robber?' or 'Who's this handsome blue hedgehog that just saved us from said horrible bank robber?'" He winked at Rose and flashed her a smile.

"Ooh! I've got one!" said Rose sarcastically with an ice cold look for Sonic. "Who's the blue hedgehog who's about to have a few blotches of black added to his blue? And if I remember correctly, I believe it was her who took the robber down." She pointed to Sally. "You just took out his lackey." Sonic smirked at her and rolled his eyes.

"I like her," said Sally with an amused smile for Sonic. "Careful, Sonic. I don't think you wanna mess with her."

"So, who are these two anyway?" asked Sonic in an annoyed voice.

"Sonic, this is The Doctor and Rose Tyler," said Sally. "He says they're aliens who came here for a 'leisure visit' to our planet."

"Oh, I see," said Sonic.

"So, like I said before, what planet are we on?" asked The Doctor.

"You're on planet Mobius," said Tails.

"Mobius," said Rose. "Where's that, Doctor?"

"I don't know," said The Doctor. "Another spooky thing about today."

"This one good-spooky, too?" asked Rose.

"I have no idea," said The Doctor.

"Okay then," said Rose.

"Now it's my turn," said Sally. "I need you two to come with me."

"Where are we going?" asked The Doctor.

"Where should we take them, Sonic?" asked Sally.

"Psych ward," said Sonic with a chuckle.

"I don't know," said Sally. "I think these two are telling the truth."

"You think they're telling the truth about being aliens?" asked Sonic.

"Well, we can all say that it's not the strangest thing that's happened to us," said Sally.

"But that doesn't mean it's actually happening," said Sonic in protest.

"If you want us to stay where you can find us," cut in The Doctor. "I think that's what you're going for anyway. I can go back to my spaceship. It's easy to find and I swear we'll stay here."

"Where's your ship?" asked Tails.

"It's a big, blue box somewhere a couple blocks down the road," said The Doctor with a smile. "Let us take you there and I can prove to you that we're not crazy."

"Wait, like a big, blue phone booth kinda thing?" asked Tails. "I saw it this morning. I had to jump over it on my way to Sonic's."

"Oh, that was you?" asked Rose.

"Yeah, you two were the people I landed in front of," said Tails.

"So, you've seen this blue box, Tails?" asked Sally.

"Yeah," said Tails.

"Well, then, Doctor," said Sally. "Why don't you lead us to your spaceship?"


AUTHOR'S NOTE: So, how'd I do? I'll try and update soon. So, read, review, alert, tell friends, and remember: Always bring a banana to a party. Haha!
