Just outside of the castle of Canterlot, hundreds of guards are lined side by side on top of the walls, in the courtyards, and inside every watchtower, all armed to the teeth to take on the incoming threat. As a small red blur known as Relv can be seen on the other side of Canterlot by the first watchtower, a loud horn blasts from the tower, soon followed by other towers sounding their horns. With the echoes of the large horns reaching the castle every sentry primes their spears, pikes, swords, shields, horns, knives, wings, and crossbows. Relv slows down and stops upon reaching the moat and the raised drawbridge into the castle. He then takes moment to examine each of the guards above and the ones approaching him from behind.

One of them on top of a wall yells, “Relv! You are under arrest! Surrender now or we will resort to using deadly force authorized by the princess!”

“…”

“Did you not hear me? Put your hooves behind your head, now!” The Earth pony follows the guard’s command and slowly places his front hooves behind his head, letting his chest drop to the stone street.

“Pathetic this all is,” he finally speaks, “she knew that I have escaped Fluttershy’s control, that I’ve escaped the guard over a thousand years ago, and have escaped from a prison worse than Tartarus, and yet, she still puts you all to die? Listen, all of you, I am not in a good mood. I am very well angry at your princess for bringing me down to such a low level. I will not hesitate to kill any one of you that get in my way. Lower the bridge if you value your life.”

“No! Seize him!” The front five guards of the ground team lung towards the downed stallion. Relv’s swords quickly levitate from their sheaves and charge at the guards. The thick blades slash at their throats, causing the five sentinels to drop dead onto the road. The rest of the guards on the ground fearfully step back as a pool of fresh blood spreads from in front of them.

Relv then roars in pure rage, “I warned you all!”

“Fire one!” Upon the guard’s command, thousands of arrows, spears, and bolts of magic are launched at Relv. Using his hovering swords, Relv deflects the projectiles coming from all sides in a rapid succession, jumping around to avoid any stray arrows. In a matter of moments, the initial bombardment ends, with Relv not breaking a single sweat. Thousands of broken arrows, bent spears, and burn marks litter the ground around the stallion. “Fire two!” As another volley of magic, spears, arrows fly towards Relv, the stallion lowers two swords flat in front of him. He quickly jumps onto it while his three remaining blades deflect the oncoming projectiles. He then hovers himself up towards the top of the wall. Several arrows and bullets of magic hit him in the process, but he eventually makes it. Leaping off of his sword platform and onto the stone wall with several guards on it, Relv is immediately bombarded by melee weapons and more projectiles. He promptly engages them, fighting multiple guards at once and punching each one out with his swords swooping around him and fighting the others. One Earth pony guard comes at him with a shield. Relv punches the shield. It quickly back off and smacks the wielder in the head, instantly knocking him out. A pegasus charges at Relv with blades attached to his wings. The pegasus flies over him and stabs him in the back with one of the wings. Relv doesn’t react however, and instead slams the guard into the ground, knocking him out. Relv then swings his body and flings the guard into another guard armed with a pike, launching the two off the wall. A unicorn guard comes up from behind and uses his magic to grab Relv by the neck. He levitates the fighter a metre in the air and proceeds to choke him.

“Unleashing Power #30: Magic Altercation!” An upper part of Relv’s back right leg glows as the hazel aura around Relv’s neck disappears. It reappears on the unicorn’s neck as he is lifted up, chocking on his own magic. The spell quickly disappears as the guard drops back down. Relv then bucks the guard with his hind legs and launches him into ten more behind him, sending them all falling from their stance. Relv looks ahead to see many guards sneaking by his three swords there and charging at him, then behind to see more passing around the other two swords and over the fallen guards.

“We got him now!”

“Unleashing Power #22: Electromagnetism!” A part of his lower right leg quickly begins to glow as the guards draw closer. Soon, hundreds of spears, swords, pikes, and shields fly from their wielders’ grip and towards Relv as they are now controlled by him. Quickly, they form thick metal cocoon as Relv encases himself inside it. The guards stop in shock and awe, now having to figure out how to get inside it.

The leader of the guards, and the one who was shouting at the stallion before, makes his way to the front of the masses with a sword still in his telepathic grip. “What the…”

“Unleashing Power #29: Hyper Strength!” Inside the metal shield, the center of Relv’s back right hip glows as he punches both of his front hooves onto the stone wall below.  Upon his hooves smashing into the stone, the entire town of Canterlot begins to shake violently. The thick wall tumbles, crumbles, and transforms into dust within seconds. The steel cocoon falls down with the wall, followed by the hundreds of guards screaming as they all plummet down to the ground ten metres below. In only a minute, the entire outside wall completely turns to dust, with only a few hundred bricks remaining in its wake.

The earthquake soon comes to a stop, as Relv crawls out of his now destroyed shield. He looks around to see hundreds of unconscious and dead armoured and bloodied bodies sticking out of the enormous dust pile. Moans of pain can be heard by the few surviving ponies amongst the carnage. Screams of terror can be heard echoing from the town of Canterlot. As Relv examines the destruction he has brought, still in his fury. “Look at this Tia,” he mutters, “this is what you brought.” As Relv continues to think out loud, the leader, still alive and clinging to his sword, digs out from the dust and sneaks up behind his target. Relv’s ears twitch as the sifting of the broken rock enters his hearing. He quickly turns around, only to be immediately stabbed through the chest and out the back with the guard’s sword.

“Ha!” Relv gives a gasp of pain and wobbles as his pours from his wounds and drips from the hilt. However, he quickly regains focus strength and gives the guard a powerful head-butt, killing him.

Hastily, Relv grabs the blood-soaked hilt of the guard’s long sword with his hooves and yanks it out before shouting, “Unleashing Power #21: Hyper Regeneration!” Immediately, his stab wounds begin to heal, as well as his other injuries received before. His swords gently hover down as he’s healing and pry out the arrows still embedded in his body as Relv looks up to the castle. “You create your mental barriers, I destroy them. You build your walls, I destroy them. You send your minions, I destroy them. All you can now have is yourself, and I will destroy you. You will pay!”

Inside the throne room, Celestia and four guards are gathered together. Two of the stallions are crying profusely over the loss of their comrades while a third one is talking to her, “He’s destroyed the wall and disabled all resistances setup. We have no idea of the casualty rate. The city is going in panic over the earthquake, and he’ll be here to get you any second now. What will we do?!”

“I don’t know!” The princess nervously exclaims, “I know he wants me dead. I’m sure of it by the extreme lengths he’s going. I’m not sure if I can pacify him. So our only option is to either disable him or kill him.”

“How?! He tore down the entire castle wall with hundreds of highly trained armed guards on it!”

“I-”

Before Celestia can finish her sentence, a stallion’s voice can be heard shouting behind the dual doors on the other side of the room, “Unleashing Power #1: Strength!” Suddenly, the massive doors fly from their hinges and crash onto the floor midway across the chamber, unleashing a massive cloud of dust to blanket the room. It quickly fades however, as the white alicorn and her four bodyguards look to see Relv at the doorway, fully healed and his long swords circling above him in a pinwheel motion.

“Relv!”

“Tia!”

“We got you!” The fourth guard shouts. Quickly, the four sentries pick up their spears and charge at the Earth pony.

“Don’t!” One of the guards reaches Relv first and attempts to jab him with his spear. Relv slides around and punches the guard in the back of the head, knocking him to the ground. He then grabs the spear and stabs the sentry in the neck as he’s turning to face upward. Two more guards approach side by side and forward their weapons at him. Two of Relv’s swords fly forward and knock their spears aside. Two more blades exit their idle animation and bash the sides of their heads and bonk them together. Now with them temporarily disoriented, the final sword flies forward and slit their throats, causing them to instantly drop to the floor on top of the first fallen guard. Finally, the fourth guard reaches Relv and chucks his spear at him. Relv dodges it and punches the guard below the chin. He whips his long silver mane around his throat and tightens it around, causing the guard to choke. Relv then backs up as one of his swords sets it hilt below to stretched silver strand. The sword immediately flies upwards, whipping the guard’s tied throat upwards and killing him on the spot. Relv then flips his mane towards the side, freeing the corpse from its hold and launching it through a stain glass window, shattering it into a thousand pieces. Slowly, Relv returns his attention to Princess Celestia, only to see her standing in front of the throne in shock of how quick and brutal his attacks were. “Y-y-you… You murdered them all!”

“Yes, and now there’s only you.” The red stallion then begins to slowly walk to her, returning his blades into their pinwheel motion beforehoof.

“W-what happened to your code? Th-they were all innocent, e-even the guards on the castle wall!”

“I’m angry Tia… My code would’ve never even lived on if I wasn’t set free. You nearly caused the suffering of millions in the future. You’ve brought me down to the lowest of the low. I always thought you were a better pony, one with actual standards. But now, now I see that you’re nothing but scum.”

“Relv, I’m sorry! I want to talk to you, and not just argue. I want to listen to you for once after all of these centuries!”

“No, no more talking. Just what you wanted, a fight…”

“Please, have mercy!”

“Fight me!”

“No! What would killing me accomplish? Think about it!”

“Fight me now! I want the sight of your blood spilling to be my final and greatest happiness!”

“You’ll regret this, I know you will!”

“Fight me!” Just as Relv is only a couple of metres away from Celestia, a bright purple light bursts from between the two. As the light dies down, the two see that it’s Twilight, Rainbow Dash, Rarity, Applejack, Pinkie Pie, and Spike. The six break from their huddle and face towards Relv, all with serious looks on their face.

“Twilight?!”

“Don’t worry Celestia,” Twilight exclaims, “we’ll stop him!”

“Don’t, he’ll murder you all!”

“Not if we work together.”

“You best listen to Tia,” Relv harshly responds, “this is between me and her.”

“Not on our hourglasses, girls, surround him. Spike, protect the princess.” The five others give a quick nod and immediately run to their positions.

With the five mares now surrounding Relv from all sides and Spike standing in front of Celestia, he reacts fast to this engagement to fight by yelling, “Unleashing Power #5: Multitasking!” Immediately, his five swords separate and each fly out to a separate target. They swing and slash at their opponents, who rapidly dodge each of their rapid attacks. As that’s going on, Relv continues his slow walk towards the princess and now Spike, increasing his speed as he draws closer and closer. Celestia looks down at the baby dragon to see his battle stance slowly break into a panicking shielding position with his arms. However, Relv’s increasing pace is broken by the sound of shattering glass behind him. He takes a glance back to see that Rainbow has left through the broken window with her perusing sword blindly following to attempt a sneak attack on Relv. “Unleashing Power #28: Quadrangulation!” As Relv stands there to regain Rainbow Dash’s bearings, Princess Celestia takes this moment and uses her magic to reveal two white fancy battle axes, bathing in a golden aura of magic, from behind the throne. She hovers them in front of her and Spike as the red stallion regains focus on them. Relv notices the axes and attempts to grab them with his mind. One of them breaks from Celestia’s control and soon follows Relv’s command, the other however, stays locked in the princess’ power. “Ivory…”

“That’s right! You want to die? Fine!” Celestia barks, the two axes lung forward and clash into each other, generating sparks as they grind. “Fight me!”

“Let’s see if your technique has improved…”

“Spike, run, I don’t want you to get hurt.” Spike promptly listens to the orders and runs behind the throne. The two massive blades separate before striking each other in rapid succession, altering angles at each swing. Relv’s axe dodges Celestia’s defensive swing and swipes it across the room at Celestia. She quickly leans back as the tip of the axe gently rubs the front of her neck. The princess then lungs her weapon at Relv and attempts at a frontward chop. Relv catches the blade between his hooves and performs a backflip to avoid Celestia’s attempt of completing the chop. He quickly jumps onto the axe as Celestia brings it back to her. Relv then jumps from the axe and tries to punch her in the face. The white alicorn dodges it by bobbing her head to the right. Quickly, she then rolls away just as Relv’s axe swipes down into the floor just where she was standing. The two clash their weapons between them, back up, and clash together again, this time, putting each other’s in a lock. Celestia takes this moment to think of a strategy.

Relv sees this and loudly proclaims, “Unleashing Power #27: Telepathy!” Upon hearing this, Celestia breaks from her thinking and focus to avoid Relv seeing what she’s planning. However, as Celestia tries to take her mind off the fight at hoof, Relv uses this to his advantage and leaps over the grinding axes, grabbing Celestia by the neck upon landing. Celestia immediately resets her focus on the fight, now discovering it was a trick. She lowers her horn directly at Relv’s face and fires a strong bolt of magic, exploding upon impact. The two rivals fly backwards from the blast, with Celestia hitting her back against a stone pillar and Relv landing just in front of the two locked blades. The two take a moment to look at each other. Relv sees Celestia’s face has become burnt and is starting to sweat profusely. Celestia sees that Relv’s face has been greatly damaged with a large bloody tear on his forehead. However, Relv’s face begins to heal itself quickly as he stands up and charges at Celestia. Without having enough time to recover, the princess panics and uses her magic to lift a section of the floor between her and Relv upwards, creating a thick wall between them.

“Please hold up, please hold up…” Suddenly, a grey light flashes right beside the white alicorn and a second Relv soon emerges from it, armed with a second silvery metal battle axe. “Oh no…” This new Relv immediately delivers a devastating punch to the grounded Celestia’s face, causing her to lose her magical grip on her axe. The first Relv notices this, breaks the lock, and brings his axe to his side. Celestia quickly regains herself from the surprise punch and teleports away just as the first Relv shatters the floor wall with a strong swing of his axe. She reappears behind her ivory axe and watches as the two Relvs give each other a brief nod. The new Relv slowly walks towards Celestia while the first goes to where the new one appeared.

“Unleashing Power #37: Time Folding!” In an instant, the first Relv with his axe disappears in a flash of grey light, leaving the new one as the now current Relv.

“Time travel, I should’ve known…” The two rivals prime their weapons once more and charge at each other. However, Celestia jumps and performs a front flip above Relv while her ivory axe dives underneath the red pony. It jabs his back legs, causing him to trip over onto his back. Celestia lands ahead of Relv’s tripped body and quickly turns to face him. She then firmly places her right hoof on Relv’s upturned belly and her left hoof on his dropped axe to hold them in place as she sets her axe’s sharp edge over Relv’s neck.  “Any last words?” Slowly, she raises the weapon a metre in the air. She looks down in hopes of seeing fear on her archenemy’s face, only to become infuriated with his unchanged disgusted expression towards her.

As she violently swings down the axe to deliver the finishing blow, Relv shouts, “Unleashing Power #34: Absolute Regeneration!” The white axe slices down through Relv’s neck, and upon hitting bone, blood was already seeping from the cut left behind the staff.  However, while the axe is still cutting, the front part of Relv’s neck immediately heals over. Relv raises his neck to let Celestia complete the cut, only to have it repaired the moment the weapon exits his body. With her axe now lodged in the stone flooring of the throne room, she immediately places her horn on Relv’s head and attempts to cast the mind control spell on him again. Relv’s body quickly becomes engulfed by her magic once more. However, just as it seems that Celestia will win, Relv screams out, “Unleashing Power #31: Anti-Magic!”

“Wha-” Like glass, Relv’s golden aura shatters as the large Earth pony backs his head away from the princess’ horn, only to quickly return and deliver a powerful head-butt onto her skull. Celestia screams in pain as she’s launched back several metres by the smash. A loud series of cringeworthy snaps echo across the chamber as the weakened princess brutally lands headfirst onto the floor. Relv gets up and looks back to see the mares still stuck fighting his swords. He looks to the throne to see Spike passed out, most likely from seeing Relv’s gross decapitation. He then turns back to his crippled opponent and levitates his battle axe to his side. He slowly walks up to the gasping mare and examines her side-laying body. Her squinted eyes are oozing a couple of tracks of blood, her mouth is slowly breathing and coughing at the same time, her chest is expanding and contracting very slowly, her chestplate and shoes are heavily scratched and cracked all over, her mane and tail have become heavily ruffled, her crown has been launched half a metre away from her head, and all across her fur and flesh were cuts, bruises, blood stains, and even a large bleeding gash over her scar, from the first time she fought with Relv.

“You have improved, I must admit. You had me used three powers, just to take out you alone. But, you were never truly a match for me. However, now I shall have my revenge, and have your blood paint every brick of this castle! And I will enjoy every second of it!”

“W-why?” Celestia chokes, “I-I th-thought-t we were f-fr-f-friends… R-remember… a-all the g-g-g-good t-times we had?”

“…”

“W-what a-ab-about Luna?”

“She will have to take control of Equestria, pray that she’ll be a better leader and take my actions for teaching.”

“S-she’ll never-” Before Celestia can completely respond, she enters a coughing fit, spewing some blood and spit from her mouth in the process.

“Let’s end this!” Quickly, Relv raises his axe above her neck.

However, just as he’s about to swing, a familiar mare’s voice screams out at the top of her lungs, “Stop!” Relv looks to where the voice came from and sees Fluttershy rapidly approaching him and Celestia. She then dives between him and the princess, placing herself right below the metal axe. Panting, she proceeds to yell at him, “Don’t kill her!”

“Get out of my way…”

“If you want to kill her, you’re going to have to kill me too Relv!”

“This isn’t your fight. You have nothing to do with her. Now get out of my way…”

“You said I am a lot like her yourself. You danced with me just like you’ve danced with her.”

“Gr… Just get out of my way…”

“What about your code? All of those guards you killed out there, think of the families you have destroyed Relv! Killing Celestia will only make things much worse for everypony, especially Luna!”

“Shut up, and get out of my way Fluttershy…” Gently, he grabs the yellow pegasus by the wing and drags her aside, only for her to quickly go back to her position.

“Never!”

“Fluttershy, get out of my way…” He reaches out for her again, only to have his hoof struck back by hers.

“Relv! Think! I know you’re angry, but still, think about what you’re doing!”

“Shut up Fluttershy! Get out of my way!”

“No! I will not-”

“I! Said! Get!” Enveloped in rage, Relv brutally grabs Fluttershy by the throat and checks her aside, unintentionally smacking her into a stone pillar. Relv resets his weapon. He swings it downwards, only for it to suddenly stop it with the edge of the blade caressing Celestia’s neck as an incredibly faint sound enters his ears. He looks to where the sound to coming from to find it’s where he tossed Fluttershy. His bloodlust abruptly ends as he sees her slumped down on the cold stone floor, facing away from him, weeping. Slowly, the red Earth pony walks towards her, stopping with his head shadowing her fallen body. He looks over the mare’s side and sees her face moist with tears, noticing a large red bruise just below her closed left eye. “Fluttershy…” She doesn’t respond and continues to sob in both physical and emotional pain. As Relv looks over the sight he has created, memories flash before his eyes, memories of him and Celestia over a thousand years ago, crying together. Relv then looks over to Celestia, still grasping onto life, then back to Fluttershy. As the gears in his head turn, Relv’s face begins to soften and his eyes begin to water. “What have I done?” Gently, he nudges Fluttershy’s back with his hoof. “Fluttershy, I-I apologize.”

“No you’re not!” She sobbingly barks. “I thought we were friends! I thought you were a pony I could trust! But you’re nothing but a monster!”

“I-I didn’t mean for my emotions to overtake my-”

“Just leave me be…”

“But I’m-”

“Leave!”

“…sorry…” Relv takes a hoofstep back from the yellow pegasus and looks at his surroundings once more, from Celestia’s mangled body, to the crying Fluttershy, to the now destroyed throne room, to the five friends still battling his swords, to the outside world with the fallen wall and Canterlot. ”By everything, what have I done?!”

“…w-why…” Soon, Relv sets his sights for the door and immediately starts galloping to it. His swords stop swinging at the mares and quickly follow pursuit of Relv. Now free from the danger of being sliced, Twilight and the others watch in confusion as Relv runs out, before setting their attention to Fluttershy and Celestia.
