Chapter 1: Close encounters of the Demonic Kind

Explosions came from the normally peaceful town of Ponyville, as robots marched through the streets, capturing citizens, left and right, and putting them in cages. Above in the skies, a familiar, evil man was cackling in the comfort of his flying vehicle, "Yes, that's right! Capture them all!" James laughed evilly.

"James, why are you doing this?!" Ashley demanded, outraged at her ex-husbands rampage.

"I want you and Toby back in my life, Ashley. After all, you did come back from the dead, right?" James asked casually.

"Yeah, after you killed me!" Ashley spat.

"It doesn't matter. If you two won't come back to me willingly, then I shall take you back!" James declared. However, something began destroying the robots, "What the hell?!" he cursed.

"Back to your evil schemes again, eh James?" James turned to see Raiden standing on a lamppost, sparks flying off of him.

"We danced this dance before. It always ends with you licking your wounds at you secret base, which we show up to later, and promptly destroy," a volley of fire erupted, and Brian emerged.

"Seriously dude, would it kill you to NOT attack us every week?" a glacier suddenly appeared, with Icezer standing on top.

"Oh, but this time, things are different," James said, as he pressed some buttons, which summoned a massive, gorilla like robot. He then parked his vehicle in the chest of the robot, gaining access to the machine.

"Didn't we trash this thing last week?" Brian asked.

"No, that was Serpenterra," Raiden replied.

"I thought that was last month?" Icezer asked.

"No, your thinking of the frog bot," Raiden replied.

"ENOUGH! You may have bested all of my robots in the past.... three months, but I learn from my mistakes! This robot is specially designed to counter each and every mutant power of your entire guild!" James cackled, as he went on the attack. He smacked away the three brothers with a backhand.

"OOF! Ok, that hurt," Icezer commented, as the three brothers went back in to fight some more. However....

500 years before Discord went rogue: The Lost City of Trotlantis

"You highness, we must do something!" a teenaged boy, who looks like the spitting image of Silver, said to a younger boy, who looked very much like Toby, only with darker tan skin, and regal jewelry. who was looking outside of his palace, as a massive, black creature was destroying everything in sight. Other worlds appeared to be floating in the sky.

"I know. But there's only one thing we can do," the boy said, as he turned to a group of children and some adults, as well as a group of seven angels and seven demons.

"My Lord, what can we do to stop that monstrosity?!" one of the demons asked.

"I wish I knew a better way Wrath, but right now, there is but one way we can seal away this evil," the royal boy said grimly. They all gasped.

"Mon roi, you do not mean....." a girl who looked like Mavis exclaimed fearfully.

"I wish there was another way, I really do," the king boy replied.

"But how will THAT stop the monster?!" one of the angels exclaimed.

"It's field of time will be tied with the city's. However, the monster will be banished to another dimension, one inaccessible by any other magic besides ours. Meanwhile, the 14 of you will be hurled eons into the future. Once there, you must find a mortal soul to act as your host. They must coincide with each of your sins or virtues," the king replied, as he began casting a spell.

Present Day: Ponyville

"Man, will this thing ever go down?!" Brian complained, as they continued to trade blows with the gorilla robot.

"It is pointless to resist me!" James taunted evilly. Just then, something on his vehicle started flashing red, "Hmm, what's this?" he questioned, examining the light, "GOD DAMMIT!" he yelled annoyed.

"What is it now?" Raiden asked.

"Oh, something's heading our way," James said, examining it closer, "You're kidding! Nothing should be THIS powerful!" he exclaimed, his voice carrying a tone of fear. Just then, the skies began to darken, as some kind of symbol appeared in the skies. From it emerged some kind of demon, who just floated down, growling at the sight of the four humans.

"What is this thing?" Brian asked.

"Hey! This is my turf! Go find someone else to hassle!" James demanded, taking a swing at the demon. However, the demon grabbed the robot's arm, and with a few twirls, threw James off in the distance somewhere.

"We weren't able to even make a dent in that thing, but this demon thing threw James like he was nothing," Icezer said, sounding amazed and terrified at the same time. The demon turned to the three brothers, looking really angry. It roared, as it went on to attack, "WHOA!" Icezer cried, as the three brothers just barely dodged the demon's charge.

"So, this thing wants a fight? When let's give him one!" Brian said, summoning 8 balls of fire, each with a different symbol, "See how you like this! 8 Sided Fire Barrage!" Brian yelled, as he launched his attack at the demon, throwing each ball of fire at the demon, each one causing a massive explosion, "Alright, that did the trick!" he celebrated.

"Don't be so sure!" Raiden warned. From the smoke, the demon came out, completely unscathed.

"Impossible! That was like having 20 atomic bombs going off at once!" Brian exclaimed.

"Let me try something. Deep Freeze: Ice Wild Javelin!" Icezer yelled, firing a barrage of ice spears at the demon. Ice formed from everywhere the spears passed. The demon then held up his hands, and blocked the attack, "No way! My ice is twice as cold as liquid hydrogen! How can this demon stop that attack with his bare hands?!" Icezer exclaimed.

"Hmm. One more try. My strongest attack!" Raiden said, as he summoned thunderclouds, "Divine Lightning: Blitzing Judgment!" Raiden yelled, as several bolts of lightning came crashing down, and struck the demon, "That was worth at least ten centuries of electricity. No way anything can survive that!" Raiden commented. The demon once more came out from the smoke, completely unscathed, "Damn! This guy must be way tough to survive our strongest attacks," Raiden commented.

Canterlot Castle,

Celestia and Luna, along with their sons had all sat down for lunch, "So, do we REALLY have NOTHING TO DO?" Luna asked, sounding incredibly bored.

"I want to say we have more documents to sign, but there haven't been any problems in all of Equestria!" Celestia dreadfully replied, smacking her face against the table, taking a large chunk out. Just then, like an answer to their prayers, a guard came in, looking distressed.

"Your highnesses! There's action down in Ponyville!" the guard said. They all shot up in interest.

"What sort of action?" Celestia asked.

"A Demon like creature. Members of the Alicorn's wish guild are engaging it as we speak," the guard replied, as another guard rushed in.

"Your majesties, something is going on at the murals of Trotlantis! The embedded jewels are glowing more brilliantly than ever!" the second guard said.

"Alright, we'll go down to Ponyville to see what we can do about this demon. And Discord? I want you to investigate the murals," Celestia instructed.

"Well, I got nothing better to do. Plus my boys are having some kind of fun with fighting that demon. Though the demon does look vaguely familiar," Discord commented, suddenly appearing.

"You've seen it before?" Chris asked.

"I want to say 'yes', but I am.... uncertain as to where I've seen it," Discord said, teleporting away.

"A creature that Discord claims to have seen, but can't remember? This doesn't sound all that settling," Luna commented.

"I know what you mean. But we should get down to Ponyville now. Who knows how long those kids can last against a demon?" Celestia questioned.

Back with the Fujiyama Brothers,

The demon delivered a hammer-knuckle, which sent the three brothers back, "GYAAAAH?!" they screamed. The demon growled, ready to finish them off.

"Damn! This guy's pretty cocky," Icezer commented, as he and his brother's struggled to get back up. The demon then began gathering power, but noticed something out of the corner of it's eye. A particular bespectacled young boy, who looked terrified.

"Toby! Get away!" Ashley cried, fearing for her son.

"T-Toby?" the demon said. It then roared in pain, covering it's face, before flying away.

"Huh? That demon thing... it just looked at Toby?" Raiden questioned, confused at what happened.

"Guys!" the three brother saw their friends, Eliza, Claire, Carlos, Simon, and Cassidy rushing towards them.

"What happened out here?" Carlos asked.

"Some kind of weird monster. It flew away just before you guys got here," Brian replied.

"It looks like those princesses from Canterlot are comin' this way. We should ask them about it," Cassidy suggested, noticing the two Royal Sisters, heading towards Ponyville.

"That demon.... I'll remember that face," Brian seethed, a puff of fire going up around him.

With Discord,

"How peculiar. They weren't glowing this brightly before," Discord commented, placing his eagle talon on one of the murals. However, something made him jerk away, "Whoa, that is some powerful magic!" Discord commented, teleporting away.

Prologue: The Prophecy continues

In a pitch black void-like dimension, something was alive, something massive, something evil, "*Growls* The time for destruction is nigh. This time, all worlds will end! And I think I'll start things off with those accursed Keepers of Harmony that imprisoned me all those millennia ago," a dark, distorted voice growled, as a pair of piercing red eyes emerged from the darkness, "And this time, no one, not even those angels or demons can stop me now! Especially since the pharaoh's true name has been lost to history," the voice cackled wickedly, as images from various worlds appeared before the creature.

14 orbs of light were scattered across a dimension plane, "The time has come," a voice came from one of them.

"We must fulfill our promise to the pharaoh," another voice said.

"Then we know what we must do. We shall all scatter throughout the multiverse, and find suitable hosts for the impending war," the first voice said, as the orbs all shot off in different directions.
