Okay, so this is my first fanfiction, so any help will be quite useful. Every little bit helps make it better in the long run. I have the story already planned out for the most part, but I am writing this when I can, so it will be updated whenever possible.
Okay, so from what I've seen here, I need to put up a disclaimer, so:
Disclaimer: I do not own Mario, Dimentio, Luigi, Bowser, or any Mario characters for that matter. However I do own the shadow guy, and some upcoming characters (I'm not going to go spoil things right here and now!)
Prologue
It had been six months since the defeat of Dimentio, and life had returned to what it used to be. Every last trace of the Dark Prognosticus had been destroyed. Mario and friends went back home to the Mushroom Kingdom. The worlds began to rebuild after the havoc Count Bleck had wreaked only months before. Bowser went back to kidnapping Peach on almost weekly attempts, and of course was stopped each time. Eventually, people began to forget what had happened such a short time ago, but that was soon to change.
Outer limits of the Mushroom Kingdom, around the area where Bowser holds domain.
The landscape was dark. Black, ominous clouds hung low in the sky. Bowser's Castle lay in the distance, surrounded by a lake of molten lava. Rivers of the stuff cut through the earth, the glow rising up as the only light source in the land. The rest of the area was desolate, with no living creatures around, and only a few torched trees left standing.
Suddenly, a slight breeze picked up. It blew across the gray earth, picking up bits of dirt as it went. The air began to ripple in a section of the air, as a box-like portal expanded and closed, leaving a medium-sized being behind.
To say that it creature was strange was an underestimate. It had a spiked head, no visible arms, and a face half black, half white. Perhaps the most striking feature was an odd purple and yellow clothing color.
It slowly floated up and down in the same position as it surveyed its surroundings, taking in what it saw. It calculated where it was, and began to think of its next move. A moment later, it spoke.
"Ah, and like the re-opening of a beloved circus, I, Dimentio, have risen!" said the being called "Dimentio." "It has been so very long since I have been able to breathe air and actually live once more! And to think, I was so close to destroying all worlds by the power of the Chaos Heart. If only that fool Blumiere and his beloved Timpani hadn't created more Pure Hearts, my victory would have been ensured..."
As Dimentio continued his ramblings, he lost all awareness with the world around him. Because of this, he failed to notice the swirling mass of shadowy particles quickly approaching him. Within a few more seconds, the swarmed him, enclosing him within a large black box.
"Hmm, now this seems to be a bit of trouble, isn't it?" mused Dimentio. "Oh well, I'm sure that I could easily escape-with magic!"
And with a snap of his fingers, Dimentio attempted a quick escape to teleport out of the box. A sudden burst of energy through the box held him back, striking him with an intense amount of pain.
"ARGH! Well, *huff* I suppose *huff* I won't be trying *huff* that again, will I?"
"Do not dare try to escape. Escape is impossible, and will only result in your death," said a rasping voice that emanated throughout the cube-like structure.
"And who do I have the displeasure to be speaking to?" asked Dimentio.
"My name is of no importance. However, I must ask you, are you Dimentio, the one who betrayed Count Bleck?"
"If I say yes, am I free to go?"
"We will decide upon that when you answer. Now, you are Dimentio, are you not?" said the voice, albeit more frustrated this time.
'I suppose there's no getting out of this,' thought Dimentio. "Oh well. To answer your question, yes I am Dimentio. The Pleaser of Crowds and almost destroyer of all worlds!" he said with a quick somersault in the air.
"Then I have a proposition for you: join up with me and assist me in helping to defeat Mario, and you'll share in the power that we'll gain. Do you agree with this?"
Dimentio floated in a circle for a few seconds, pondering what to say next.
"Well, the offer, while tempting, is something I simply must refuse. You see, I do not want any amount of power if I cannot have all of it."
"That's too bad. Because you must accept, or I will destroy you."
"Destroy me? My good man, I believe you are quite mistaken. For you see, I could no doubt destroy you without even batting an eyelash."
The voice didn't seem phased by this. "If you doubt my power, then why not try a taste of what I can produce?" said the voice, as a surge of energy burst through the box, laying heavy damage upon Dimentio.
"Uncle! Uncle I say and have mercy upon me!" yelled Dimentio as he tried his best to reduce the pain induced upon him by the burst.
"So you see what I am capable of now? Are we in agreement? You help me defeat Mario, and you can get a share of the power and control we shall have?" asked the voice.
"Well, I guess I have no other choice," Dimentio said. "Sign me up for your cause."
"Excellent." All of a sudden, the box began to break away, as the particles began to reconstitute into a more humanoid shape. The entire body consisted of the dark particles, except for the head and the hands, which were pure white. The hands were simple two-fingered and one thumb parts, and the head had empty, white sockets for eyes, as well as a mask-like covering for the mouth. No other features could be distinguished on it, no matter how hard you looked.
"Now we shall discuss the contents of my plan. Listen well, for you play a crucial part in this, and your reward shall be great. So tell me, just what do you know about the Mega Stars?" asked the being, as both it and Dimentio warped out of the area, returning it to its unsettling calm darkness once again.
