I've actually come to enjoy this ending about as much as the real one, if not more. Plus, it's too long to put after the AN, so it gets its own chapter.

--------------------------------------------------------------------------------

Silence seemed to press down on the two mares as they walked through Ponyville. Pinkamena had taken Pinkie's form so that they could converse easier as they walked. The buildings around them seemed to scream through open doorways and windows; openings left by the fleeing ponies days before. An odd smell hung in the air, a stench Pinkie knew quite well by now. It brought her back to her work, each bringing her more pleasure than the last… until recently. Pinkamena inhaled deeply, relishing the smell she had been created to enjoy.

"Our work is done," Pinkamena said, looking over at her counterpart. She made no attempt to hide Pinkie's memories as she was wont to do; it was more fun to leave the fragile mare to her heartache. "We have finally done that which we were made to do."

"Yeah," said Pinkie, the final screams of thousands of ponies finally pressing on her mind. It wasn't uncommon for one or two, or even several ponies to stay in her mind, their death throes disrupting her throughout the day. But usually she managed to remember the thrill it all brought, the joy of the kill, the sweet taste of fresh blood on her lips. Now, a dam had broken somewhere in her mind and her victims had been released at once. Their tortured screams pulled at her sanity, threating to destroy her. Nothing she did could silence them, or even redirect their fury. She looked over at her doppelgänger, silently pleading for assistance, "What do we do now?"

"Whatever you want dear Pinkie, the world is ours now."

They continued walking on in silence for a few minutes, the wind whistling through the abandoned town. A strange sound began echoing through the air, disrupting the unnatural silence. Pinkie tried to focus on that, rather than the disembodied screams that haunted her, but even machinery in a dead land couldn't distract her. Pinkamena ignored it, anything still around would either give out soon or seek them out, and nothing was likely to so much as scratch her at this point.

The metallic clanking grew louder and louder. The mares could now hear the hiss of air as pistons worked furiously to move the seemingly heavy burden. "What is that?" Pinkamena asked, now growing irritated.

"How am I supposed to know?" Pinkie asked, "You're supposed to be the smart one!"

"First of all, if I'm the smart one, what are you?" Pinkamena began stepping heavier than usual, causing her hooves to sink into the ground until her leg was completely buried before ripping it out of the ground effortlessly. "Second, you have that stupid oracle, remember?"

"I'm the fun one," Pinkie said, smiling as big as she could. The smile made Pinkamena wince and rub her jaw, she couldn't imagine opening her mouth that wide. "And the oracle doesn't answer any more, I guess it still needed a connection to Nightmare Moon to stay around, but she's gone and Luna's dead, so it had to go away." Pinkie didn't like the smile that spread across her double's face at this.

"That's good to know," Pinkamena yelled. The noises were now loud enough to shake the ground and surrounding buildings. If Pinkie hadn't killed her a month ago, she would have sworn that Vinyl Scratch was washing dishes or something.

The noises quit just as Pinkie had been about to yell back. The twin mares froze and looked around, something was clearly wrong. Pinkie didn't feel any of her senses going off, but it was possible that those depended on a connection to Nightmare Moon as well, so she stayed on guard.

Nothing moved in the surrounding area, and Pinkamena sensed no movement. She was about to suggest continuing when a silver and gray blur shot out of the sky and slammed into the ground before them. One of her hind legs was planted beneath her, one foreleg almost resting on it. Her other forehoof was planted in the ground near the middle of the crater caused by the strange mare's landing. Her other rear leg was stretched out behind her. It seemed almost that she had hoofed the ground to make herself land.

The gray mare looked up, light reflecting from the metal covering much of her body. 'Not covering it,' Pinkie realized, 'that is her body.' Exposed mechanism whirred and spun deep within the pony's flesh. It was obvious that she was alive, but it was equally noticeable that certain modifications had been made. Half of her face had a metal plate bolted and welded over it, with a red visor extending over a small black dot that could only serve as an eye. Pinkamena noticed with a chuckle that whoever had made the changes probably wasn't very skilled; the mechanical eye seemed to be looking up and to the left, while the normal eye, a bright yellow, looked down and to the right. One of her flanks was made of a thick metal skeleton covered with a strange looking mesh, wires and gears twisted through the openings, some screeching in need of oil. Seven blue circles had been painted onto this to make it match the flesh side of her legs.

The biomechanical creature looked up, the black eye narrowing beneath its visor. The edges of the mechanical eye began spinning quickly and a red glow began developing in the eye. "Hey Pinkie Pie!" the creature yelled, its voice rising and falling sporadically, though still somehow sounding normal.

"Deh- Derpy?" Pinkie managed, taking in the perversion of life and science before her.

"See ya later Pinkie Pie," the strange Derpy yelled, just as happy and strange sounding as before. The eye was now a bright red with sparks flying off of it.

"Derpy?" Pinkie cocked her head, staring at the mare before her, "what are you-"

"GET DOWN YOU IDIOT!" Pinkamena yelled slamming Pinkie to the ground and jumping around a nearby corner.

Barely a second later, an enormous red beam shot through the space where Pinkie had just stood, instantly vaporizing much of the street and the house that had been behind Pinkie.

"Luna's plot! Derpy what are you doing?"

"Just makin' some muffins Pinkie Pie!" she said happily, seemingly unaware that she was shouting, "You were takin' too long so I started makin' em instead, but I don't know where you keep your special ingredient and I'm almost out!"

"How did she find out?" Pinkamena glared at Pinkie.

"How should I know?" Pinkie was cut short as they dodged another searing beam. Pinkie felt the heat from it and she realized that a semi-circle had been vaporized in her mane. "No talking," she said, hearing Derpy's now unmuffled steps just behind them, "just run!"

--------------------------------------------------------------------------------

It wasn't long before the two mares arrived back within the bowels of their hidden fortress, armed to the teeth with things Pinkie had 'found' or constructed over the years. A repetitive crashing sound from above told them that Derptron was quickly smashing her way in; they didn't have very long before the fight.

"I can't do this," Pinkie sobbed as the ceiling began shaking; they were two floors above the torture room, the staircase to the meat locker was right behind them. "I Pinkie Promised that I wouldn't hurt Derpy."

"No you didn't," Pinkamena said angrily, she knew that without Pinkie she could easily lose this fight. Life and science where never meant to meld in this way and she knew even her strength was little use against something so powerful. "I was there, remember? You swore you'd never harvest her, or more specifically, you swore never to put her through what you put that Luna-damned unicorn through. Just avoid hammers, microwaves and hairspray and you should be fine." She knew the limits placed on Pinkie's promises by her blood oath, made all the more binding by her darkside's awakening, but she also knew that this little technicality was enough to save her skin so she went with it. "Just shoot her with that thing and you should be fine."

The two mares were outfitted in thick metal suits designed for Pinkie. They were cobbled together from scraps of old Special Forces gear, both pony and griffon issue, so it was more advanced than even some of the top level technicians had to work with. Pinkie's had several missile launchers attached to the shoulders filled with tiny, heat seeking 2K12 KUB missiles. One arm of her suit was a glowing blade that popped with the heat; the other was a long, strange looking tube with electricity running up and down the sides. Pinkamena's had two massive claws for the hands. It has recently been outfitted for her from one of Pinkie's heavier duty models. The claws had been ripped straight off of construction cranes when nopony was looking. A massive hole was in the middle of the abnormally thick chest plate, hot plasma dripped slowly out. On the back was a large canister filled with lava, a hose attachment connected with spray guns stuck to her rear hooves.

Derpy burst through the door. All four of her legs were now fleshless, whirring blades had replaced the old pony legs. "Oh great," Pinkie groaned, "She found the storeroom." A new grenade launcher sprouted from Derptron's back and what could only be a black hole generator replaced her lower jaw.

"Why didn't we take that?" Pinkamena asked, glaring at her smaller counterpart.

"I don't know! I can't think of everything!"

Both of Derptron's eyes were now enormous black circles rimmed with metallic plates. They whirred angrily, sparks of every color flying out.

"Great," yelled Pinkamena, throwing her hooves up in exasperation, "she found the harmonic fusion batteries!"

"Muffin time!" Derptron yelled.

"How did she say that?" Pinkie hissed, "Her mouth is gone!"

An enormous rainbow patterned beam of light shot from Derptron's eyes melting a hole through the yards of steel that made up the room's wall and continuing on through the stone. Pinkie jumped up, the tube on her arm now fully charged. A huge blue ball of lightning shot out and struck the floor where Derptron had been standing. She had somehow moved out of the way without either of the mares noticing. She landed behind them, a click shattered the air and Pinkie was forced to roll away from the grenade launched at her face.

"Derpy stop it!" she yelled, cutting wildly at the launcher with her blade-arm as she fell, "it's not nice!"

"No," said Pinkamena, "but this is." She slammed the claws down onto Derpy fast enough to crush the mare. She picked her up in one mammoth claw and began smashing her to the ground repeatedly, too fast for even Pinkie to follow. Suddenly there was a loud tearing noise and the claw flew free, smashing against the wall in a cloud of dust. Derptron emerged from the cloud with lightning speed, the whirring blades that had replaced her legs cut deeply into Pinkamena's side.

Turning quickly, Derpy shot another grenade at Pinkie followed quickly by a double laser beam. The pink mare didn't stand a chance. Just as she rolled away from the blast, her body was engulfed in the rainbow colored heat. She screamed, the noise all but drowned beneath the frying rock behind her. What was left fell to the ground with a small thud, the mass of metal plates glowing white hot.

Derptron turned away, preparing to finish the shadow pony when another scream of pain sounded behind her. Pinkie was throwing off the suit she'd been wearing. Her fur was burned off and the skin a mixture of charred flesh and deep red burns. She charged at the cybo-pony, screaming in rage. Even her abilities couldn't save her from injuries like this for long. She jumped onto the metallic pony; most of the flesh had been removed by Pinkamena's last attack, and began biting at the support struts. Her teeth failed to find purchase but still she ground, trying to fend off Derptron's blades until she could finish.

Pinkie managed to bite into one of the struts and ripped it out with her teeth, unfortunately, as effective as this was, it distracted her just enough for the blades to move in. Pinkie's head fell to the floor with a sick thump, blood spewing everywhere, being shoved out by the force of her still beating heart. Throwing the body off of her, Derptron moved on to finish things.

Pinkamena stared. Pinkie dead? No, no, no, no, this couldn't be. This was impossible. Nothing could do that, especially not so easily. She could feel the silence deep within her mind, she was alone. Pinkamena had never been alone since the moment she was created, always she had the company of Pinkie Pie to share the darkness of reality. No more. "I will destroy you," she said, still watching Pinkie's head as it rolled away.

"Muffins?" Derpy asked, cocking her head slightly. The device in place of her mouth began glowing and Pinkamena's face paled.

'Oh horseapples,' she thought.

The black hole exploded into being in the center of the room. Pinkamena dug her hooves into the ground, filling the excess room with lava from her pack. The blood dripping from the wound in her side instantly chilled the molten rock, firmly cementing her into the thick metal. Luckily, this is where they had tested the device; the room was designed to hold together in case of accidental black hole escapage. Unfortunately, a similar device was present in the black hole generator and it kept Derptron from being pulled in by the immense gravity.

She walked slowly towards the immobilized Pinkamena. "You killed Dinky."

"What are you talking about?" Pinkamena asked, "Luna's mane! Who is Dinky?"

"It was you, you killed her. I know, I was there!" Small droplets of light somehow began falling from Derpy's strange eyes and Pinkamena could tell she was crying. "You did it. And now you'll pay!"

The metallic mare leapt forward, prepared to rip this beast to shreds, this monster that had taken her precious little muffin away from her. Acting quickly, Pinkamena ripped her legs from the floor and spun, kicking Derpy in the face. Derptron flew through the air, momentarily caught by the black hole which spun her around and sling-shot her back at Pinkamena whose forehooves were now solidly in the ground. She lifted her forelegs, blades spinning like propellers. They pulled her faster and faster towards the trapped creature. Suddenly, the creature lifted its legs, the black tubes by the hooves turning bright red.

Thick streams of lava shot out and struck Derptron in the face. The force of the jets knocked her backwards just as fast as she had been approaching; the heat melted most of her body, leaving a screaming shapeless chunk of metal to fly through the air into the distortion in space time that hovered above the floor.

With the destruction of the device that spawned it, the singularity collapsed upon itself sending out a violent shockwave that ripped through the air. Pinkamena felt herself nearly ripped from the ground by the sheer force. It was as though the attractive forces of the massive gravity had all been reversed. She could feel her side splitting farther now, her legs held in place while the rest of her was forced away. She knew this wound would end her, especially now. That was fine. She was alone, and Pinkie was waiting.

--------------------------------------------------------------------------------

Just wanna say that in the scene where Derpy entered: I was so tempted to make her Iron Mare instead of a cyborg.

This, much like the alternate scene, was suggested by my editor Saph34, such a great guy. I would have included this in the story, but Pinkie already said that nopony hurts Derpy and I had the memory of Pinkie giving a Pinkie Promise not to hurt Derpy…. Also, I refuse to include a basilisk either way. (Sorry Saph, but I've given Pinkie way to many toys as it is.)

Anypony who got that thing with DJ Pon-3 washing dishes /]*[\

Wait, what is that?

Oh nothing, just my- BASS CANNON!
