ENORMOUS AUTHOR'S NOTE: Hoo boy, what am I getting myself into here? Well, please, bear with me here for a moment, folks, I'm one of those losers that feels the need to explain everything out in detail before it gets underway, so...Well, first and foremost, constructive criticism is very much appreciated. If nothing else is achieved of me posting this story, I would at least hope to get a few pointers on my writing style, and how to make it better (or good in the first place, perhaps). I have a very low opinion on my writing skills, so if I really do suck, I'd like for someone else to tell me exactly why, and how much. And hopefully, if I do, how to fix it. Particularly, I feel that I'm very bland at describing things, so I probably overcompensated in my attempt to inject flavor into my sentences, if I did, please tell me so. I also think my dialogue lacks emotion or depth, so that will probably be glaring as well. Yes, yes, I know it's not very wise to point out a story's faults before you can even read it, but that's just the type of idiot I am, I can't change that.

Okay, onto the story summary. I plan on making this a very large two part story, and this is by far going to be my most ambitious attempt at a fanfic yet. This is going to be one of those "ooh, they're all living in a mansion isn't this original" type of deals, and it's going to be centered around Sonic, so if you dislike either of those premises, you probably won't like this. I plan on keeping most of the characters as in-character as I possibly can, with the exception of two or three for story reasons. As I said, if all goes according to plan this will end up being a very long, two part story, and as such, will probably take me painfully long to finish, so if by some chance anyone actually ends up liking this story, don't expect it to be finished anytime soon. I don't really have a genre for the story yet, but I plan on there being a pitiful attempt at mystery later on. Hopefully, if I get any kind of positive feedback, it'll spur me into being a better writer by that time. If I have anything else to point out about the story, I'll do it in author's notes at the ends of chapters. Oh, one more warning, I have a terrible, non-existent sense of humor, so don't expect anything that appears to be a joke to actually be funny.

Well, if you're still reading, I guess I'll shut up and get on with the actual story. Reviews are obviously nice, but if you don't leave one that's fine with me. Flames are accepted as well, if your opinion of me is that I should go eat a bucket of whale dongs, then by all means, feel free to tell me, but don't expect a reply, because I dislike arguing. Anyway, I hope at least someone enjoys this.

Disclaimer: I don't own anything mentioned in the story, everything belongs to their respectful owners.

Sonic The Hedgehog set his bags down in front of the magnificent structure that sprawled out before him and whistled in marvel of it. He hadn't quite expected it to be so breathtaking, but the Smash Mansion was the definition of cutting edge. He had only meant to rest for a brief moment before heading inside, but he stood in place for well over a minute with his mouth slightly agape, the reality of his situation setting in the moment he laid eyes on the gorgeous architectural wonder: he was a Super Smash Brother.

Never in a million years had Sonic expected to get an invitation to the prestigious group. Sure, he knew he was well-known enough, but he had always figured the disdain the Mushroom Kingdom seemed to harbor against his homeland in the past would've prevented him from ever hoping of becoming a member. So the hedgehog was genuinely surprised when he woke up one morning and found an elaborate, royal-looking letter postmarked from the Mushroom Kingdom to him on his doorstep.

~Five Days Ago~

It felt almost surreal for Sonic when his plane (piloted by his best friend Tails, of course) touched down in the Mushroom Kingdom. Not expecting a pleasant greeting at all, he was caught off-guard when he and Tails were welcomed with open arms. As he left the airport, Sonic waved good-bye to his pal, and began carrying his bags towards the large castle that loomed in the distance. Preferring to walk for once, so he could get a sense for his surroundings, Sonic felt awkwardly uncomfortable walking through the streets of Toad Town, as people stopped and stared at him with wide eyes, murmuring to one another and pointing. Not enough to break his stride, Sonic coolly made his way through the town's main hub, taking the time to casually greet or wave to the crowds of onlookers as he passed them. Finally, he found himself staring at the gateway to Peach's castle, two enormous, blue metal doors with a large star painted in the center of them. Pushing them open, they parted surprisingly easily, and before Sonic stood his destination, Princess Peach's castle.

He had thought the castle was awe-inspiring as well when he'd seen it for the first time up close. He didn't have quite as long to admire it, however, as within moments of his arrival, the large, oak double doors that made up the main entrance of the castle swung open, and out stepped a dainty looking blonde-haired woman in a pink dress, who had a joyful, welcoming look on her face. Accompanying her was an elderly looking Toad with a yellow and brown mushroom cap and a fine mustache, who sported a frazzled and worried look.

"Welcome to the Mushroom Kingdom!" said the woman in a bright, cheerful voice. "You must be Sonic The Hedgehog, we've been eagerly awaiting your appearance!"

Usually the first to carry a conversation, Sonic felt uncharacteristically uncomfortable in the presence of foreign royalty.

"Y-Yeah, I'm Sonic. Nice to meet you, Princess... Uh..." Sonic scratched the quills at the back of his head as he struggled to remember the woman's name.

"Peach Toadstool." the woman finished with a giggle. "But most people just call me Princess Peach."

Sonic returned the warm smile Peach gave him. He began to feel much more comfortable following the princess' casual demeanor and speech.

"And it's a pleasure to meet you too, at long last!" with another giggle, Peach added, "Everyone is just dying to meet you, especially Ma-"

"Now, now, princess." interrupted the elderly Toad fussily, "You'll have plenty of time to acquaint Mr. Hedgehog with everyone in a short while, but first we must sort out the matters of his citizenship papers, licenses, arrest records, shoe size..."

Peach rolled her eyes as the old Toad rambled on, then leaned towards Sonic and whispered "Oh, don't worry about Toadsworth, he's just an old fogey who wouldn't know about fun if it bit him on the-"

"P-PRINCESS!" Toadsworth shouted, as Sonic couldn't help but let out a chuckle. "I-Is that any way to speak to a guest? And from a princess, no less? Why, your parents would be absolutely livid, I'll have you know!"

Toadsworth continued on with his lecturing for quite a while, much to Peach's dismay, and seemingly forgetting Sonic's presence entirely, but eventually led Sonic into the castle alongside the princess. Sonic marveled at the beautiful and extravagantly decorated rooms and halls as he was led from one to the next, and eventually was beckoned into a very small (by the castle's standards) room, where he was asked to sit down at a desk across from Toadsworth, who took a seat in a chair that made him tower over Sonic and his little wooden stool. Peach decided to take away Toadsworth's fun and nudged the chair's height adjustment handle with her foot, causing Toadsworth's seat to plummet below the desk.

Laughing, Peach left the room before Toadsworth had time to retaliate with another long-winded lecture, and silently mouthed "Good Luck" to Sonic as she closed the door behind her. Greatly annoyed and flustered, Toadsworth tried his best to mask it as he got out a file with Sonic's name on it and began asking him a series of seemingly random questions at a brisk pace. Sonic barely had time to get out one answer before the next question was shot at him, as Toadsworth scribbled away furiously without missing a beat.

Finally, after what seemed to Sonic like hours, Toadsworth told him everything seemed to be in order, and congratulated him on becoming an official Mushroom Kingdom citizen and Smash Brother. Sonic quickly thanked him and shook his outstretched hand, and hadn't taken one step out of the door before he was set upon by the presence of Princess Peach and a short, mustachioed gentleman wearing a red cap emblazoned with an "M", a matching red shirt, crisp-looking blue overalls, and impeccably white gloves that very much resembled the pair Sonic wore. He looked at Sonic with a friendly smile, and stuck out his hand as Peach introduced him.

"Sonic, I'd like you to meet Mario, the savior of the Mushroom Kingdom."

Sonic flashed Mario one of his usual grins and slapped Mario's hand in a high-fiving manner.

"Yo, nice to finally meet you, Mario!" Sonic said, as although he had heard of the plumber and his exploits many times before, this was the first time he had ever had the chance to met him in person. "Seems like you lead a pretty busy life, from all the stories I've heard about you!"

"Ah, I am-a nothing special." the plumber said modestly. "I-a just do my best to keep-a the kingdom safe."

Sonic could tell he was warming up to the Mushroom Kingdom already, as both their princess and the most famous person there were as friendly towards him as his own friends were.

"But I have also-a heard about-a your adventures as-a well, Sonic." Mario added, "It-a seems to me that-a you're probably as-a famous in-a your home country as-a I am in-a mine!"

Grinning sheepishly, Sonic replied, "Heh, well, you know how it is, you stop a crazy megalomaniacal nutjob from trying to take over the world a few times, and suddenly you're hailed as a hero!"

Nodding, Mario replied with a laugh, "Aha, do I-a ever!"

~Present Day~

Thinking back to that day, it seemed to Sonic like it was months ago when he met Mario and Peach, when it had been less than a week in actuality. He smiled to himself as he thought of how well he and Mario had gotten along, as they had talked for hours, regaling each other of their many, many adventures. Pumped up and ready to go, Sonic prepared to knock on the big, oak doors before him that were emblazoned by an "S" on one door and a "B" on the other in very fancy gold lettering.

But before he had the chance to, it opened from the inside, once again revealing Princess Peach, looking every bit as serene as she did five days ago.

"Oh, hello again, Sonic!" she greeted in her usual bubbly voice. "Welcome to the Smash Mansion!"

Just a short little prologue, I plan on making the chapters much longer than this. If you spot any typos or grammatical errors, please tell me so I can correct them. Right now, I have this and two chapters written, so I'm posting them up simultaneously. As previously stated, CC is greatly appreciated, feel free to be as harsh as you want, because I honestly would like nothing more than to know how to improve my writing abilities. And, if anything I write in any chapter irks you, feel free to tell me or ask my why I wrote whatever in such a way so I can attempt to explain my feeble reasoning. Oh, and tell me if I should cut out Mario's "accent" in future chapters. GOD, WHY DO I RAMBLE SO MUCH? D:
