Okay, well, yes, I suppose you can say this isn't "original," but this is my take on what the Super Smash Brothers Melee Tournament would really be like, though considering we have plumbers who throw fireballs and, eh, Pokemon, it isn't real, but honestly, you get my point. Anywho, here goes, these characters all belong to Nintendo (Assumably.) and blah-de-blah.

Super Smash Brothers Revisited
Chapter 1: Invitations

Mario let out a loud, gaping yawn as he sat quietly in his living room, a game controller in his hands. He clicked the various sticks and buttons to guide a man dressed in a red hat and overalls over hills, past evil turtles, and through pipes. Personally, it really couldn't be helped but to remind him of something.
Then there was a knock on his door, and he got up, and pressed the button on the television to turn it off. Then bound over to the door, peeking through the small hole to see a circular image of a small Toad, waving a pink envelope.
Mario backed off, unlocked the door, and pulled it open. "Telegram for you, Mr. Mario, sir." The Toad said in a small, squeaky, voice. "A thank-a you." He nodded, and the Toad gave him the letter with a smile, then turned and bound away as Mario closed the door. Mario flopped back down on his couch, and read the address aloud:

"To-a Mario and-a Luigi, the Plumber Brothers
The Mush-a-room Kingdom"

There wasn't anything that really said where it was from, but it had been sent for him, and the Mushroom Kingdom post office obviously felt it was okay. So, he carefully slid open the flap, and pulled out a small slip of paper. "Luigi, come-a look at this, it's-a for you, too!" There was an incoherent response in Italian from the other room, and Luigi walked out, dressed in a night gown and cap.
"You-a need to stop sleeping in, why-a do ya' think I'm the one everybody likes?" Mario smiled playfully, and Luigi grumbled, scratching his eyes and wiggling his nose. "What's it-a say?" Luigi reached over to a nearby hat rack and pulled off a green cap with an "L" printed on it as he read to him:

"You are-a cordially invited to Mr. Master's estate for a competition of-a the strongest champions of the Mush-a-room Kingdom, and beyond! There are-a riches and gifts beyond your wildest dreams if you-a compete and win.
It's-a state-of-the-art, with a holographic arena generator and-a dorms for all the competitors, further details will be-a explained. All you have-a to say is "Yes." Please respond. Immediately.

Mr. Masters and Company"

As soon as Mario had reached the line concerning gifts and riches, Luigi's eyes were already glazed over and drool was hanging lazily from his mouth. "Sounds-a good to me." Mari shrugged. "There's a catch, there's-a always a catch." Luigi snorted, "I say-a we do it. The King of Koopas has been silent enough-a, hasn't he?" Mario couldn't help but to agree, and he glanced at the letter again and walked over to set it on a desk. "I guess-a our answer is-a yes."

There was a deafening whooshing noise and both Mario and Luigi were swept violently through a beam of blinding, white light. It threw a wind through the room, and the invitation seemed to evaporate completely in all the chaos.

Elsewhere, across dimensions, in places completely unknown to the Mario Brothers, let alone the entire Mushroom Kingdom, similar things happened. Heroes whisked away in the night by white light. Some claimed they were aliens, others said it was the Gods, or Gods, or the like.

Somewhere, Link, who had been given a letter by the mailman, read it, and only thought to himself: Yes, I have to do this! And was gone in an instant.

Samus Aran, who was fending off vicious Space Pirates in a distant galaxy, received an e-mail on her visual screen, and accidentally shot the Space Pirates entire ship, turning the whole side of the moon into a flaming inferno. And, despite her rage as she read the later, muttered a decision to go. And the remaining Sky Pirates saw her disappear and rejoiced as they continued their illegal activities.

Ash Ketchum, visiting his Mom with his companions by his side, received a message from the Pallet Town Postman, and looked at it, puzzled as to why it was sent to Pikachu. He opened it, misunderstanding it as a request for a challenge, and with a loud "Yes!" he was thrown backwards as a beam of light swirled around his Pokemon.

Roughly twenty-five contestants, torn from their homes, and for that matter, their dimensions of sorts, and tossed into somewhere completely foreign. As they fell through utter whiteness, they saw something fade into shape. The white faded away to reveal an octagonal platform with a black strip down the middle. With neaon patterns of purple, black, and rainbow-reflective metal, somewhat resembling half a lightning bolt on either side.
It seemed unbearably small, but as people fell from above it and landed with a thump, it seemed that they themselves must've been shrinking, for it somehow fit them all. As they got their bearings, they saw others around them. And what seemed to be travelling through a swirling vortex of dark-hued colors. A visible light piercing it in the distance, getting closer.

"Where are we?!"

yelled a seemingly anthropomorphic hawk, or a falcon, named Falco Lombardi, who had been reunited with his team member, Fox McCloud. And there was a booming laughter, and a certain Princess Peach let out a scream.
"Do not be afraid, Princess, I am Mr. Master, and I'm quite sure you all, ahem, read about me?" And you could easily picture him smiling. "I am the host of this tournament, and I'm not the one who brought you. You brought yourselves." There was mocking laughter from Falco. "My ass! Did you miss the pyrotechnics?" There was hushed murmuring round him.
"No, no, I certainly did not." Master's voice boomed from all directions. "But then again, you all said 'yes', more or less." And there were gasps and exclamations as the realization dawned upon everyone, "All you have to say is 'Yes.'" Is what the letter had said, very plainly. But ofcourse, nobody had taken that seriously, which Master likely expected.
"This is a tournament, ofcourse, and I have christened it Super Smash Brothers, which I think is quite catchy. And hey, if nothing else, you'll get your bloody rewards as the winner." But there was more retaliation. "What if we don't want to fight?" This was from Zelda, the Princess of Hyrule. There was a sniff from Mr. Masters.

"Well, that sucks for you."

And, oddly enough, there was no overall response to this. "Well, then, if that's over, if you would kindly turn to the back of the platform, here's something I want you to see." And everyone did so, and realized that no one had been paying attention to the formerly-a-dot of light in the distance, it now nearly engulfed the view and an image formed within it.
But before anyone had time to process this, there was a bubbling swoosh and a platform-wide case of jet-lag.

"Welcome.. to Earth."

There were gasps of astonishment as the platform soared over a vast forest of enormous trees, which couldn't have been more than thirty-feet below them. A green forest as far away as the eye could see.
"This is not your world, for any of you, for that matter, this is simply the Nexus of all of yours, the Nintendo, the network of all your dimensions combined into one center. Here your 'adventures' are presented as ideas and imagination, but honestly, I'm quite sure it's the inter-dimensional stress." He laughed, but every else either didn't think it was funny, or were too absorbed in the view.

"Well, this is it now anyway, most of your dimension's times move years faster than Earth's, ofcourse, with my 'connections' I've seen that they ruin it with factories, mining, and war. Much like Brinstar, Samus." Though no one understood much of anything Mr. Master was talking about, the causal way he said Samus' name slid a chill going down her spine.

"Well, anyways.."

There was a fizzling, and the entire world around them wavered and distorted, until it seemed to collapse down onto itself, fading away in unison until it slid into the now plain, metal floor. "What just happened?" Wher'd that place go?" "What magic is this?"

Master made a discontented groan, "I know some of you are from medieval sort of places, Hyrule, Mushroom Kingdom, and Donkey Kong Island, if nothing else. But honestly, evolve already! The Earthens are already killing tigers with rocks! It's the holographic arena generator, that I mentioned, already. I know they can read in the Mushroom Kingdom, Mr. Luigi. Or did your brother read it to you?"
Luigi looked angry and muttered for a bit, but looked absent-mindedly about him.

They were in a large stadium, made entirely out of metal with velvet seats in hundreds of rows, several stories up. They were in a large, circular area at the bottom, with glass panels decorating the floor around them, and projectors sticking out of the walls on the sides of the arenas.

"Now, the dorms are.. through there!"

A door slid open quietly at one end of the arena, steps leading up into darkness, a man with brown hair and a blue cape stepped up to it, and lights lit up on the edge of the stairs going all the way up.

"So, see you bright and early tomorrow? I can hardly wait, I've already got all your names in a hat!" He laughed the same eerie way he had when they had arrived, and the voice of Mr. Masters was no more.

Yes, I actually worked the Nintendo title into it, sue me, I don't own it, in't that good enough? And as a note, I don't know every single character's background as well as I know others. Like Mario, Donkey Kong, and Samus, I know pretty well, but still.
