-In the Everfree Forest, a little before the Blackout-
Amy and Pinkie Pie fly through the trees in their super forms, with golden streaks behind them, "So Pinkie, did anyone get hurt in Rockville?" Pinkie giggles, "Nope, I blasted all those shadowy ghosty guys away. How was guarding Ponyville?"
Amy then sheepishly says, "Took out those little things with ease, but I may have caused a small earthquake." Then Amy looks around, "You see the Tree anywhere?"
Pinkie's tuft of hair twitches to the left, "Oh! Oh! There it is, finally got it on my Pinkie-Radar. C'mon Amy!"
They both zoom beneath the canopy of leaves to find an old castle that is across a canyon connected by a rickety bridge, Amy asks, "What is this place?"
"This is where me, Twilight, Dash, Rarity, AJ, and Fluttershy solidified our friendship and defeated Nightmare Moon! Who was actually Princess Luna. Who isn't evil anymore. Anyway, this place is super-duper sentimental for us." Pinkie says as they land on the ground in front of a cave.
Amy looks up at the cave, "I can sense the Element Emeralds in there with Twilight, as well as a… massive wellspring of power."
Pinkie then responds, "Holy hay! You're right, that's a crazy amount of power. We should say hi to Twilight."
They enter the cave, and Twilight is standing in front of the glittering Tree of Harmony and talking to herself, "There everything is now in place now to try his spell again." Her eyes and horn glow with dark magic and she tries to cast it on the Tree, but it fails, she groans in frustration, "How come some robot can cast Celestia's spell, that resets the elements, but I can't my version to turn this Tree into a smaller… more moveable rock! This is so annoying."
"Hey Twilight, watcha doin'?" Pinkie says while looking up at the Tree.
Twilight turns around, in her super form, and her wings splayed out, "Oh gosh, well this is embarrassing, but hello, Amy, Pinkie. What are you two doing here, you handle your shadow-imp problem?"
"We did beat up all the ones that showed up, and then they stopped appearing. Me and Pinkie thought that the Tree of Harmony would have a ton of those things but seems like they didn't show up." Amy says.
Twilight ponders while looking through various books and notes she has scattered about the place, "I was moderately concerned about that, considering that the Master knows where this is, or at least he said he did. That's why when Rarity sent me that message with her ability about all the shadows, I doubled my efforts to make this darned Tree moveable."
"I wonder why today this is happening…" Amy thinks out-loud as the cave gets darker and darker.
"Hey, who's turning the sun down!?" Pinkie yells
Twilight stops what she's doing, "Wait what?"
She warps outside to see the sky turn black, she spreads out her wings, her horn and eyes glow bright, as her aura sharpens and expands, then she fires a small beam that creates a small star in the sky, like shining a flashlight on a black sheet. This single star expands and multiplies rapidly to millions of little glowing dots in the sky, giving a decent amount of illumination.
"The sky is covered in such dense darkness; I hope what I did helped in some way, and I hope the princesses are okay." As Twilight ponders, she goes back inside, she says to Amy and Pinkie, "I cast a star spell on the sky, its improvised but it should hold for a long while."
"That's still scary that the sky practically disappeared, I think I'm gonna stay with you Twi. If this doesn't have something to do with our evil mastermind, I'll be shocked." Amy says this and she then manifests her hammer, "That guy's probably gonna come here too so, you do what you need to Twilight, me and Pinkie will keep you safe, right Pinkie?"
"Absolutely! No baddies are gonna get through us! We're powered up, pink and ready to throw down!" Pinkie yells out while bouncing.
Then they all sense it. Something dark erupting in Canterlot. "What-what just happened, why did my whole stomach just drop." Pinkie says fearfully, as Amy grips her hammer, "Something really bad is in Canterlot right now. If we can feel it from here, it makes whatever we've fought recently look like a joke." Amy says anxiously. Then she walks toward the cave's exit, with Pinkie behind her, as Twilight continues to blast spells at the tree.
As the two stand there for a minute, Pinkie looks on the ground and sees pebbles shaking violently, then they start floating upward, her tuft of hair points to the left, her eyes widen as she jumps toward Amy to save her from something, Pinkie yells out, "Amy, Look out!" as she pushes Amy, four long tails smash into the stone where Amy's head once was. Amy's eyes widen recognizing the tails but then hears, "Damn you and that little power you have, Pinkie." As Pinkie Pie hears the voice, she recognizes it, but she knows it isn't Kilo. it's Fist.
As he breaks the tree line, they see an upgraded Fist, he was given part from his failed partners, but all given a purple coat of paint. He still has a metallic body, like his initial Metal Knuckles form, but he has nine twisting tails, his hands are not like Knuckles' and instead look more like Lix's hands but with the same empty holes where the knuckles are that shoot out crystal blades.
"Man, this is destiny. I get to find the Equestrian Emerald and I get to kill two pink shit stains. it really feels like my birthday." Fist says arrogantly as he lumbers close.
Pinkie and Amy flare with energy as he comes closer, "Stay back, freak, you are not welcome here, turn around and go." Amy says with authority. Fist points at both of them, "Wait a minute, you guys are starting in your super forms? That's not very fair. C'mon Pinkie, that's not very nice, I gave you the emeralds to power you up when we fought, can't you do the same for little ol' me?" Pinkie vehemently shakes her head, "Uh, no! You tried to kill us! I'm never gonna give someone evil like you a single thing! Besides why are you back? Didn't we kick your muscle-brained butt?"
Fist's voice gets angrier, "Let's not mince words, Pink, you killed me. You, Rainbitch, and the blue bastard, took my body from me." Then he chuckles, "But I still won. Got myself a little promotion for getting those emeralds, my boss, Mephilzo, let me pick from Kilo and Lix's blueprints to upgrade myself. I got Kilo's tails, and I also took Lix's databanks, so I know all of his tricks."
"So you're boss's name is Mephilzo?" Amy asks.
Fist responds with his arms crossed, "Yeah, he lifted the mental block, because he's on the planet, so I and my good buddy Prism can sing his praises or whatever. If you want my opinion, I don't really care about ruling Equestria or whatever, I just want to fight strong people and get stronger, then someday I'll kill Mephilzo myself. Until then, it'll be smooth sailing. Now which one of you ladies want to fight me before I Reverse Roboticize and kill the western hemisphere?"
After Fist's threats leave his robotic speaker, Pinkie bursts off the ground, she blazes toward him at faster than light speeds, she throws a Party Favor at him, he smiles ready to take it to the chest, but then it hits him and explodes with a much greater force than when they fought before, Fist flies back, his chassis already damaged. This is as Amy drags her hammer along the ground running alongside Fist. He turns his head while he's flying through trees, only to see Amy's red eyes streaking with a glow as she runs.
She raises her hammer high and slams it downward as hard as she can on Fist's Chest, it snaps on impact, this craters Fist into the ground, and he bounces off the ground. Amy tosses her pommel and summons two hammers one in each hammer, Amy positions one hammer under Fist while he's in the air. Then launches him upward with a booming force, as he reaches the apex of his ascent. Amy teleports and bashes his head between her hammers. Fist's eyes almost blink off, as his monitor eyes crack.
She then bashes Fist in the head and the chest with both hammers at the same time, he gets blown away with the force, and he flies through the air, until he hits Pinkie's hoof that explodes with an energy ball she charged preemptively, but as Fist falls Pinkie feels a tug on her leg, as one of Fist's tails wraps around her leg.
Fist laughs, "HA! Got you!"
Pinkie's eyes grow wide, as jets erupt out of Fist's shoulders pulling him and Pinkie to the ground. Pinkie tries to get away, but Fist grabs the tail that Pinkie's leg is stuck in. The other tails provide extra pull as Fist yells out, then whips Pinkie to the ground and when she slams into the ground, Pinkie gets dragged across the ground, then gets pulled back toward Fist, who clotheslines her as she gets launched backward. Pinkie slams the back of her head on the ground, and she coughs up blood.
"Pinkie!" Amy yells as she grips her hammers tightly and rockets toward Fist, then in a swift motion, Fist puts his guard up, he parries one hammer and slams her in the side of the head with a nasty haymaker. Amy doesn't budge as she stares down Fist with a fist in her cheek, she pulls her head back, forcing Fist to stumble, and Amy slams her forehead into Fists, making a cacophonous clanging noise, this also dazes him. As Amy bashes him in the side with a hammer, he gets flung forward a few feet then grinds his feet on the ground, to stop himself. Fist look at Amy kneel down to Pinkie, who takes Amy's hand and stands up.
Fist puts a hand on his head and a dark energy circulates through his body, "No. No. No! I will not lose a second time. Not to these weak, nothings." He looks up and his eye is trembling in madness, and his body starts to shift, "You people are going to die. Going to die. Die. Die. Die!"
As his voice gets louder his body starts to morph like Super Fist, his metal plates become a dark purple fur. The other difference being his nine tails become extraordinary long, and cover themselves in matching purple fur, but the tips harden to points with them being made completely of crystal, and as he transforms another tail appears, bringing it up to ten.
His hulking body hunches over. He breathes out through his mouth reveling razor sharp teeth. He howls with laughter as his tails wriggle on his back. "Love this transformation, don't need a single one of those stupid rocks also since I was Super Fist before…So call me Ten-Tailed Fist."
His eyes look at Pinkie, "Alright Pink, let's see if I can do this." He opens his palms, and all ten of his tails point toward the hands, then they all start to glow. Black static starts to form in his hands, then a purple orb highlighted with black manifests and Fist then yells "Star Buster!" as a blast of dark purple slams into Pinkie, he holds up her hooves and tries to hold it back. She realizes it's too powerful. Then Chaos Controls out of the way, as she appears, Fist is already there with a gut punch ready. Pinkie dodges just like she would normally, then she feels a blunt punch from the side make contact. As she flies off from the punch, Pinkie sees Fist's hand is missing down to the elbow the missing part of it is exiting out of a portal. Fist pulls his hand through smiles condescendingly and says, "Gotcha. Feel lucky my claws aren't out, or that've killed you."
Pinkie feels blood gushing from her nose, and she then looks up at Fist and she smiles too. Her eyes looks at Fist glazed over, "How many people you think are laughing cuz of me, huh Fisty?"
Fist looks at her with a confused glance, "One or two? I don't know, why does that matter?"
As they speak another Pinkie Pie walks out of the tree line, then another one and another one, I gets to the point to where there are twelves Pinkie Pies are bouncing around. "You can clone yourself, how is that in anyway impressive?" Fist crosses his arms while hovering.
"On its own, I think it's pretty neat, had to use Chaos energy to copy what the mirror pool did, and it was some real work to make them coordinate but it's not my special Element ability. My element is Laughter, the more ponies I'm around who I've made laugh, the more energy I get. I can even store it. But there's no one around her for me to cheer up. So, I sent these Pinkies all over Equestria to make everypony feel better after those mean shadow monsters came around. I kept that power around just in case." Pinkie looks up and wipes the blood from her nose, as she continues looking at him all of the Pinkies close their eyes and turn into energy that the main Pinkie absorbs.
Her golden aura flashes with pink static erupting in the air, Fist falls to the ground, feeling the raw energy, his fur stands on end like a cornered cat. Swiftly all of his tails light up with energy as he creates a massive energy ball. Pinkie looks at him, her pupils completely dilated, and her smile huge across her face. "Are you high or something, what the hell is going on here?"
As she chaos controls into the air, Fist adjusts his aim, and Pinkie raises her hooves above her and charges her energy, it first balloons out, larger, and larger. Fist starts to sweat, as her energy ball is almost blocking the view of the sky, then Pinkie condenses it. Each condensing makes the energy more and more compact. Compacted until it's as large as a wagon.
Then she balances it on one hoof and tosses it like a baseball at Fist and she yells out, "Smile Bomb!" Fist tries to combat it with his own attack, as his fires, he holds it back for a moment, but he had forgotten that Amy Rose was in the fight. While the struggle takes place, Amy conjures the largest hammer she can before the head of the hammer is wider than the base of six or seven oak trees, and more than twice as tall the trees. Amy grips the handle, and she makes a 180-degree swing horizontally, she yells out, "100 times Piko Hammer Slam!" as she slams her hammer onto Pinkie's attack, sending it through Fist's attack. Fist tries hold up the blast and the hammer, but the hammer detonates the attack.
The explosion of the Smile Bomb breaks Amy's huge hammer, and the Piko hammer disintegrates into light. The bomb also creates a spire of pink energy that vaguely sounds like laughter that stretches into space. Pinkie and Amy stand basking in the brilliant light.
The energy thins out and disperse. though the immense energy leaves crackles of pink electricity, Amy, and Pinkie land at the bottom, as they see the barely breathing form of Fist, grayed, and charred from the blast, his mouth agape. Fist stands up. Then he laughs his arm sloughs off and fades to dust.
"I can do one last thing, just to make you people lose." Fist says this as the char blows off of him from the kick-up of energy. He chaos controls, Amy and Pinkie follow him, now on high alert.
They all arrive at the Tree of Harmony in front of Twilight, who just managed to cast Lix's spell reverting the Tree of Harmony in a massive, white, hexagonal cut gem, or the Equestrian Master Emerald. As he takes in a split-second of information, Fist's single arm has a claw pop out, he cuts a hole open in space-time, grabs a single cyan colored Element Emerald and throws it in before he falls to the ground and looks up at Twilight. The last thing he sees is Twilight's horn glow as she grabs him with magic and tries to throw him out, but she puts too much power into it, and he becomes a black bloody smear on the ground. Twilight looks at him and says, "Oops. Didn't mean to do that. That guy took one of the emeralds, that is going to be such a pain."
"We'll have to debrief you later, but the master's name is Mephilzo, and we should get to Canterlot as soon as possible." Amy says with a hammer in her hand, then Twilight responds, "Okay, we should go, and I'll leave the Elements- ", as she turns, she watches as all the emeralds are enveloped by a black cloud, then in a burst of energy they all vanish.
"No!" Twilight yells as she runs over to the empty spot where the tree once was, as it leaves the entire forest goes quiet, "Without that Master Emerald the Everfree's environment can't sustain itself!"
"Twilight we gotta go! If they disappeared that means that Mephilzo has 'em!" Pinkie yells out in concern. Twilight's horn charges and they all feel the ground start shaking, and they start sensing something else happening in Canterlot a massive charging of power. Twilight looks in the direction of Canterlot with her eyes wide, "Fluttershy?"
