“Alright, time for a new song!” DJ Pon3 remarked as she put in a CD and began playing ‘Dark Bowser/Dark Star Core Theme’ from Mario and Luigi: Bowser’s Inside Story. “I didn’t know that we were going to deal with this!” Sparkler exclaimed in alarm and worry. “You did when we signed up for this!” Rainbowshine protested to her friend with an annoyed expression.

At this moment, the Main Six and Spike hid behind some rocky cover while watching Mephisto the Destroyer make it’s terrorizing display of the power the likes of nopony has witnessed before. “Rainbow, how do we stop this thing?” Applejack asked Rainbow. “Why ask me?” Rainbow shrugged. “’Cause you’re the one that said you’ve done a lot of nutty things before we decided to follow Spike on his dragon quest and save him from those teenage dragons who were bullyin’ him!” Applejack pointed out in annoyance.

“That was different; I don’t know if this thing has a weakness!” Rainbow protested. “But does it have strengths?” Pinkie asked with a curious expression. “Um, maybe…” Rainbow answered. “Oh dear, that doesn’t sound good to hear.” Rarity commented. “No, it doesn’t at all.” Fluttershy responded. “But what about weaknesses? Surely pony dragon hybrids have weaknesses, right?” Twilight mused.

“Um, maybe…I’ve never seen a pony crossed with a dragon before. It’s cool and uncool at the same time with seeing one for real, y’know?” Rainbow shrugged. “Well, we have to defeat it somehow!” Spike exclaimed, watching the creature destroy a rock.

“Remain calm, my friends! I am coming!” Thor shouted out to his friends while he was about to rush in and join the ongoing battle when…”Oh, goodness!” The alicorn dodged an incoming spell that exploded a few feet in front of him. “Where do you believe you are going?” Loki asked as he soared across the skies and appeared a few feet between Thor and the battle that was going on behind him.

“I am going over there before you got in my way.” Thor remarked, gesturing to the battle happening behind Loki. “Do not toy with me, Thor!” Loki snapped in anger. “You and I have a FINAL issue to settle!” “Wait, were we playing some game?” Thor asked as he pretended to forget about the battle. It took a lot of patience for Loki to not lose to Thor’s ignorance, but…”RARGH! It is only you and ME! We fight to the death until ONE of us survives!” Loki declared loudly.

“You actually believe we can fight to the death? That is insane! We are gods and Alicorns; we are immortal!” Thor asked with a wide eyed expression. “I do not care! Prepare to die!” Loki hissed with a wicked and sly expression, firing a spell in Thor’s direction. “And he does it again with the spells…” Thor groaned to himself while he dodged the attack.

“Just be lucky I made this battle fair, Thor!”

“You call fighting you while you are constantly firing spells at me ‘fair’?!”

“My answer, yes.” Loki smirked as he and Thor charged at each other, using their powers or the Elements to fight one another. The ponies and dragon dodged Mephisto the Destroyer’s next attack. Spike cried out, “Look out!” He dodged another attack from the hybrid. Pinkie commented, “For some reason, I can’t help thinking about the possibility of the existence of some strange parodies of different movies where WE play the characters of whatever movies were parodying when the ACTUAL characters ponified are nowhere to be seen or mentioned.” The others groaned on how random she was being at the moment.

“If only we had a sword or some sort of weapon…and some way to expose this thing’s weaknesses.” Spike said with a disappointed sighed. “Then, it’s toast!” “I don’t think we have somethin’ to expose it’s weakness!” Applejack said with a frown. “Perhaps I may have something to expose it’s weakness.” Zecora volunteered with a smile, holding out some sort of red stone. “A way to show the weak spots…” “Zecora, you’re a lucky savior!” Apple Bloom exclaimed to Zecora with a grin.

“Thank you, I do my best.”

Zecora used the red stone and the whole area flashed red. Soon, five weak spots appeared on Mephisto the Destroyer’s chest, one of his arms, his neck, one of his legs, and his tail.

“Now, we need a weapon.” Rarity said with a frown. “But what kind of weapon would be needed to stop Mephisto the Destroyer?”

“Then, it’s time for this unicorn to hop into this battle. And to summon the weapon I made!” Twilight commented seriously as her horn glowed and summoned a weapon that looked like a mix between a sword and a giant key with a gold handle with a rainbow colored metal attracted to a gold curve covered in gems, a silver hilt emitting light that had light green carvings that resembled fire with scrolls on it, a head at the end of the shaft that resembled the top of a heart, and key chains that resembled the gems on the Elements attached to the end of the handle.

“Amazing, I’ve never seen a weapon like that before.” Celestia said in amusement. “My student, let us fight this monster together.” Twilight got onto Celestia’s back and the two flew at the enemy, dodging a laser beam. Twilight slashed at Mephisto the Destroyer’s chest, causing him to roar in pain.

“Alright, go Twilight!” Spike cheered happily. “But there’s no way that Twilight and Princess Celestia can hurt him unless they get Mephisto the Destroyer to turn around.” “Oooh! Oooh! I got an idea!” Pinkie called out before she turned to the monster. “Oh, goodie! Mephisto the Destroyer, look! A defenseless pony!” Mephisto the Destroyer turned and breathed fire out at Pinkie.

This allowed Celestia to fly in and fire a spell at the hybrid’s arm, causing it to roar some more. Mephisto the Destroyer looked furious as it launched missiles at the unicorn and alicorn who dodged them quickly. Fluttershy yelped, “Eeep! That wasn’t supposed to happen!”

“I agree!” Rainbow nodded with a worried expression. “We must distract him even further!” Rarity commanded. “Come on, everypony!” Granny Smith called to the other ponies in determination. “Time we teach this monster a lesson!”

“Guards, charge at the monster!” Frigga commanded quickly. The ponies and dragon attacked Mephisto the Destroyer, the monster shot out it’s attacks and swiped at it’s enemies. Of course, it’s enough of a distraction for Twilight and Celestia to fly in and hit it in the neck and leg which left only one weak spot left: the tail. “One more weak spot to go!” Twilight exclaimed urgently. “Right, we must keep up, everypony!” Celestia commanded to the ones watching the battle. Those who weren’t fighting off Mephisto the Destroyer fought off the soldiers still standing or flying. Then, ‘Masked Dedede Theme’ from Kirby Super Star Ultra began playing as both Loki and Thor continued their fight, the brother on Equestria and Ponyheim’s side was gaining the advantage, putting his adoptive brother in a force field and firing lightning bolts from his hammer at him a few times.

“GRAAARGH!” Loki screamed in fury, breaking out of the prison. He tried to fire a spell, but Thor blocked the attack with his hammer. “Fascinating attempt, Loki, but there is one more thing. LIGHTNING RAGE!” Thor roared as he fired out a bunch of lightning bolts from his hammer, sending Loki right through a wall before he jumped in after him. “FALCON BUCK!” Loki can only get up in time for his adoptive brother to buck him in the chest. The villain could only pant as he backed away, still injured from the previous battle. “You cannot do this to me! ME, THE GOD OF LIES AND MISCHEIF!” Loki exclaimed to Thor with a groan of pain. “I am sorry, but you leave me no choice.” Thor said sternly. “And now…LIGHTNING—“

“No, no, no, DO NOT DO THIS!!!”

“STRIKE!”

Thor fired a lightning bolt that sent Loki right through the roof; the villain got out of the blast as it headed off towards the sky. The villain landed on the ground, looking furious.

“Did YOUR father teach you that?! Or did you learn that on your own?!” Loki snarled in fury at Thor. “Because you just sealed your fate, Thor!” Loki fired spells at Thor who dodged them and flew up, head butting his adoptive brother right in the chest and then threw his hammer at him; both fighters landed on the ground as they continued their fight around the ruins. The group of ponies (and one dragon) in a fairly equal moment against the creature of darkness that Loki had created. It looked like they could hang in there just a bit longer and then they might win…or so it seemed. “Wait a minute!” Thor exclaimed to the villain, pointing out to a bunch of flames that appeared and formed near a window. Suddenly, ‘Last Boss Cackletta’ began playing again as a familiar being Loki knew reappeared.

“Nexus, what are you doing here?” Loki asked in surprise. “You have done well, Loki, but the ponies are still resisting, I see…” Nexus commented. The others took notice at what was happened as did Thor and only the Princesses’ eyes widened in fear in…who Loki was talking to. “Yes, I cannot believe that this is happening to me! Unfortunately, the secret weapon you gave to me is about to be defeated by those ponies since they found the weaknesses!” Loki yelled in annoyance. “Oh, how tragic…” Nexus muttered. “You will defeat those ponies, I swear on it.” Since Loki was too distracted with talking to Nexus, Thor was trying to muster up a powerful attack on both of them.

“What is THIS?!” Loki demanded furiously in seeing Thor trying to concentrate. “Apparently, your adoptive brother is trying to defeat both of us at the same time…” Nexus answered with an evil smile. Suddenly, Thor released a huge lightning bolt out of his hammer. “NO! NO! NOOOOOOOOOOOO!” Loki screamed in horror as he held his hooves up in defense. BAM! The attack sent Loki flying off who knows where. Truer words could never escape anypony that saw this…Loki was beaten, but in an image they could’ve imagined. “Sister, Loki has been…” Luna gasped in shock. “I see it, sister! And now we know who had a motive for this.” Celestia nodded with a stern expression. Soon, Thor stopped his attack and then looked at where Nexus had appeared.

“MWAHAHAHAHAHAHAHAHA!” Nexus cackled. “Until the next time we meet…entertain me where my reign lies! I shall be watching your troubles…from afar.” The Overlord King then vanished, leaving no trace of where he was while the background music stopped playing. All the ponies that were in the battle were so shocked at what happened that they nearly forgot about their battle with the monster Loki created from his darkness. But luckily, Luna fired a spell to push the deadly beast away, getting the others to snap back to reality.

“EVERYPONY, DO NOT SPACE OUT! WE STILL HAVE TO SAVE EQUESTRIA FROM LOKI’S LATEST BEAST!” She commanded in her Royal Canterlot Voice. Then, as Thor sighed to relax in seeing that he’s finally defeat his adoptive brother, something unexpected happened.

Loki then got up and glared at Thor while panting in exhaustion from the attack. This got Thor worried as he asked, “How did you...I thought I have defeated you!”

“Ha! You believe I can be defeated that easily, hmm? I can see that you are not willing to quit.” Loki responded with an evil chuckle. “Not a chance!” Thor retorted. “That is what I was hoping for!” Loki smirked evilly.

“Holy cupcakes!” Pinkie gasped in shock. “Loki’s not giving up!”

“Of course, I knew he wasn’t going to give up that easily. We can only hope that Thor can defeat him, but now we have a monster to face.” Private Katoptris groaned. Pinkie grinned as she called out, “Hey, DJ Pon-3! Put in ‘A Fire Will Rise’ from the Dark Knight Rises for this part of the battle!”

“Ok, here we go!” DJ Pon-3 exclaimed, putting the music into the player while the music began. Mephisto the Destroyer roared as it swiped at the gang, keeping them away from it’s last weak spot. “Curses, why can’t he hold still?!” Dr. Hooves demanded with an irritated expression from inside the Lizard Giant 6000. “I can’t hit him!”

“We must keep trying!” Luna commanded to everypony. “Even if Loki is defeated, there’s no guarantee that his monster would go away!” Twilight and Celestia charged at the hybrid, trying to hit the tail. But the monster turned and fired lasers at them both, sending them to the ground hard.

“Twilight, Princess Celestia!” The other members of the Main Six yelled. “Let me have him!” Rainbow exclaimed while charging at Mephisto the Destroyer who slashed at her, causing the Pegasus mare to fall to the ground. “Ow! I think it got my wing!” Applejack growled furiously and yelled, “Mephisto the Destroyer! YOU WILL NEVER EVER GO TO HURT ANOTHER ONE OF MY FRIENDS AGAIN!!!” Mephisto the Destroyer fired huge laser beams at Applejack, but she jumped out of the way and bucked the pony dragon hybrid right in the tail, Mephisto the Destroyer roared in pain as it fell to the ground.

“Take that, ya freak!” Applejack exclaimed with satisfaction and determination. “Princess Celestia, Twilight!” Spike yelled as he ran to Celestia and Twilight who have fallen on the ground. “Are you two ok? Please, be alright!” “It’s ok, Spike.” Celestia groaned, having Twilight slide off of her back while the weapon disappeared. “That monster didn’t hurt us too much.” “I dealt with worse, Spike. You know that.” Twilight grumbled as she checked herself for any damage. “I took on Nightmare Moon and Discord and I’m still alive and well.”

“At least you’re both ok.” Spike sighed in relief. Meanwhile, both Alicorns continued their battle, attacking and trying to hit each other. “Thor, surrender!” Loki said with an angered expression. “Leave now!” “I cannot.” Thor responded sternly to Loki. “My friends need me.” “Why must you pick defending those ponies instead of surrendering?! WHY?!” Loki demanded angrily.

“Because…they care for me.” Thor said gently. “And I pity you, for you lost yourself in the darkness of your heart and this poisonous dream for control.” “This is your last chance, Thor!” Loki snapped, backing Thor against a wall. “Leave…now…”

“I…said…no.” Thor said in a calm yet fierce tone. “Then you leave me no choice...” Loki growled grimly and darkly. “Well, if I am going down, then I am taking you with me!” Thor shouted.

He grabbed Loki and jumped out of the window. Loki kept on letting out battle cries as he quickly flew away from Thor. The two kept on fighting in flight and then they landed on the battle field. Everypony stopped as the two Alicorns glared at each other.

Thor and Loki got into their battle stances as they prepared for battle. The first alicorn roared out, “LOKI!” He had a rainbow colored aura around him as his eyes went pure white. “THOR!” Loki snarled while he had a dark green aura around him and his eyes were flashing. “Everypony, get down!” Shining Armor yelped. “It looks like this battle’s coming to a climax!” The ponies, Spike, and even the army moved as both fighters glowed then started shooting a huge blast at each other; Loki with his magic and Thor with the Elements. “This is turning into a major conflict here!” Private Katoptris commented with a worried expression. “At this rate, who knows who would live and who would die?!” Luna exclaimed in worry. “NO! Thor can’t die!” Twilight yelled frantically. “He has to live!” “YOU CAN DO IT, THOR!” Spike cheered on the alicorn. “Yeah, kick his flank!” Apple Bloom exclaimed. “Go on, Thor! You can do this!” Rainbow and Pinkie cheered.

“Thor…please win.” Twilight begged. Thor nodded as he pushed forward, Loki quickly doing the same thing. And soon, both the Elements and Loki’s magic collided, causing a huge explosion. “Whoa, get down!” Big Macintosh exclaimed as the ponies and Spike ducked to avoid the attack. Most of the soldiers gasped as they were either blasted away or turned to dust while they got caught in the explosion. In fact, only a few members of the army remained.

“Applejack!” Apple Bloom screamed in fright. “I’m scared!” Sweetie Belle yelled, hugging Apple Bloom and Scootaloo. “Hold on!” A voice shouted. The Cutie Mark Crusaders turned to see Truffle Shuffle and Featherweight running up to them. “We’re coming!” Featherweight added. “Hey, wait for me!” Berry Pinch called out as she ran after the two colts.

“Hold on, Spike!” Twilight said to Spike who got a hold of Twilight’s back leg. As they got closer to the Cutie Mark Crusaders, Truffle Shuffle, Featherweight, and Berry Pinch shouted together, “We got you!” “Hold on!” Spike yelled to the foals.

“That explosion’s getting closer!” Berry Pinch shouted in worry. “We’re doomed!” Featherweight cried out. “Hang on!” Rarity shouted as she got a hold of the Cutie Mark Crusaders, Truffle Shuffle, Featherweight, and Berry Pinch while summoning a barrier around them. Soon, the explosion disappeared as the dust cleared.

Everypony still standing watched as Thor was standing and breathing in and out. The explosion had taken a lot of energy out of him, but he was still alive. So is Loki who was staring in disbelief with bruises on his face as his armor vanished from his body. He moved a bit and pointed his hoof at the Main Six and Spike who moved back nervously…then he mumbled in anger, “I am not over with yet, I shall have my revenge on all of you ponies soon…”

It looked like everypony was going quiet after a long battle and it seemed like they were all going to go back home and go on with their daily lives…but they were wrong. Suddenly, without warning, just near where Twilight was standing, Mephisto the Destroyer came in, still going and about to attack the unsuspecting unicorn. “Twilight, watch out!” Thor commanded while he pushed Twilight out of harm’s way.

But in exchange for saving Twilight, Thor got caught in the creation made by Loki in the sudden end. BAM! Then, without anyway of stopping this action on time, Mephisto the Destroyer ignited it’s flying system to take off at such a fast rate that even the Ponyheim Army was not fast enough to act on time. “Thor!” Twilight called out in panic.

“Son!” Odin and Frigga shouted at the same time. They were almost about to pursue their son, just like any other parent would for their child except…There was a glowing flash in the creature’s eyes; the familiar sense of a magic aura was covering the monster. “No, it is going to self-destruct!” Odin gasped in horror. “He’s going to self what?” Pinkie asked with a confused expression.

“The creature is going to explode and take out almost an entire sky area; we need to protect you all when that happens.” Frigga explained in worry. “No way; what about Thor?” Applejack responded in disbelief. “Right, I gotta go fly up and—“Rainbow began, but was cut off by Odin who was blocking her way. “You FOOL! Even a god’s protection may not hold against what power that creature can unleash!” Odin warned the Pegasus. “But then Thor would be—“Fluttershy began to protest. “It is about to happen! All Alicorns and unicorns, put up magic barriers around anypony!” Frigga commanded, watching all the unicorns and Alicorns summon barriers around the Earth Ponies and Pegasi (even Loki set up a barrier around himself and the remaining soldiers of his army).

“But Thor’s still up there!” Rarity protested. At this time, Mephisto the Destroyer was soaring higher and higher with it’s grip on Thor not letting off. The alicorn didn’t know what this thing was doing or how it could be still active. He thought he himself saw this monstrous beast beaten already, so how was it that the creature made from the darkness that Loki spoke about was still wanting to go on? “Ugh, unhand me, you foul creature!” Thor groaned in annoyance. BEEP! BEEP! Just then, Mephisto the Destroyer had it’s eyes flash with the aura completely surrounding it. “All targets must be eliminated, so says the will of Nexus’s Law!” The creature proclaimed in a robotic voice which made Thor puzzled. “Engaging Explosive Meltdown!” “WHAT?!” Thor demanded with a shock expression. “T minus 30 seconds!” Mephisto the Destroyer declared.

“Ugh…” Thor groaned while trying to pull loose from the monster’s grip. “20 seconds…” Mephisto the Destroyer continued as Thor managed to get his left hoof free from it’s grasp. “10 seconds…” “No, no, do not explode now!” Thor pleaded, finally getting free.

“5…4…3…2…1…0!” Mephisto the Destroyer finished. At this moment, what happened next caught everypony off guard. There was a bright light in the skies, but the unicorns and Alicorns quickly set up the barriers before…it happened. BOOM!

The others could just about register it, a huge explosion like a super nova happened. The entire area was having massive hurricane winds blowing and ground quaking underneath everypony, this happened for a short time until it…ceased.

Then, when everything seemed to have calmed down, something impacted the Earth that were 5 necklaces, a ‘big crown thingy’, and a familiar looking hammer; it was the Elements of Harmony and Thor’s hammer. Many saw that they were lying there, smoking a bit, but not damaged and that wasn’t the worst of it. What truly had some ponies’ attention was that something ELSE was missing from having the Elements and the hammer, where was the wielder of the hammer, where was…Thor.

“No…” Twilight gasped while running from behind Odin followed by the other members of the Main Six as tears rushed down her face. “Thor, why? No…no…no…NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!”

“YES! YES! THE THRONE IS MINE!!!” Loki cheered with an evil smile as he ran towards the Elements and Thor’s hammer with his remaining soldiers, only to get cut off by two Royal Guards blocking their path. “No…Thor…” Spike muttered sadly, hugging the Cutie Mark Crusaders.

“No…Thor…” Luna sighed with her mane covering her face. Twilight commented sadly, “I can’t believe it…Thor’s really gone.” “Well, there are more sequels to this one coming out soon and rumor has it that Thor’s gonna be in the next one.” Pinkie pointed out. All the heroes groaned at Pinkie being herself. “This is TWO friends Loki has cost me...first Dinky, now Thor. MY sole consolation in this case being that at least Loki won’t go around hurting everypony IF we arrest him.” Twilight explained sadly. Many were now lowering their heads with grave and sorrow expressions on their faces (except for Loki and his some of his soldiers who were smirking about Thor’s ‘death’).

Many saw over the battle that they fought in, much destruction has happened, much has been laid to waste here. Even though the ponies of Equestria may have won the battle against Loki’s Army, the price by the ending result was too high to pay. Lives that many didn’t want to see lost. Frigga grabbed Odin’s hoof and began sobbing against his chest while the Ponyheim Army had blank sadden expressions as they looked at Odin who shed two tears in witnessing the lives lost for each other. One was for the loss of Teslan Aegis whose brain was bashed by Loki’s bare hooves. The other…was the brave sacrifice of his true son who saved the ponies of Equestria’s lives from Loki’s madness.

Suddenly, something crashed onto Spike, sending him to the ground hard. Private Katoptris turned around and asked in alarm, “Spike?” “Ow! Somepony get this thing off me!” Spike complained. The others came over and gasped upon what they saw what landed on their dragon friend: it was Thor, but the alicorn was barely breathing and alive. “Thor!” Most of the ponies exclaimed while rushing over quickly. Celestia walked over and checked on him.

Celestia spoke up in worry, “Thor is barely breathing…he won’t have much time. We must get him to a hospital fast.” Twilight nodded and stared at Thor in sorrow. But all hopes can’t come true, can they? “Hello? I’m still stuck here!” Spike called out while he was still pinned down by the unconscious Thor. “Anypony; help!”
