Third-person Pov: Ponyville.

The sounds of battle echoed through Ponyville as minions whooped and cheered at the carnage! The Diamond Dogs were caught with their pants down as they helped themselves in looting Ponyville.

"Go forth, minions! Make your Overlord proud!" Gnarl shouted evilly as the minions did exactly that, smashing and killing anything in their path of destruction with whoops and hollers as they ran about the place!
"Twilight dearie. Where did you find these, and I say this in the nicest way possible, ruffians?!" Rarity questioned as she looked and cringed at the path of carnage and mayhem the minions were reeking as they battled their way to Sugar Cube Corner.
"It's more accurate to say they're the ones who found and rescued me, Rarity. I'll tell you the rest of the story once we find the rest of the girls and Spike!" Twilight said urgently. She counted herself lucky to have saved Rarity in time; who knows what's going on with the rest of her friends?

Looking back ahead, she turned to one of her minions. "How close are we to Sugar Cube Corner?" The brown minion, who was wearing the same helmet as the leader she killed at the beginning, looked at her eagerly and was about to say something when the sound of a cannon being fired was heard, followed shortly by an echoing scream.
"AHHHHHH!" A Diamond dog crash-landed into the dirt headfirst, burying the unfortunate mutt halfway into the dirt as confetti fell around him, much to the amusement of the minions. Who cackled at the dog's misfortune!
"Well, that answers that..." Twilight turned to look in the direction of the flying mutt and saw Sugar Cube Corner's roof...and heard Pinkie Pies's crazed laughter as her party cannon fired again.
"Hahaha! I think I'm going to like this friend of yours!" Gnarl said with an evil grin, no doubt enjoying the mayhem that Pinkie was causing to the Diamond Dogs.

They continued their march to Ponyville's bakery and saw that the place was surrounded. Pinkie Pie's party cannon popped in and out of the various windows, each shot firing destructive party goodness, sending the besieging dogs flying with faces full of confetti and cake.
You would think otherwise but Pinkies barrage of devastating party favors was reaping a surprising toll on the dogs. Many of them, especially what looked like younger dogs, cowering behind hastily set up barricades, one of them even sucking his thumb!
It just so happened it was the thumb sucker who spotted them and shouted a cry of alarm.

"Well, there goes the element of surprise. Oh well, not like browns are very sneaky to begin with!" Gnarl remarked as the Diamond dogs decided to take their chances with the arriving Minions and their Overlord over besieging a bakery protected by a pink monster.

It was over 80 diamond dogs charging the minions, each equipped with crude armor and weapons, versus 66 of Twilight's minions, most of whom were newborns who only carried clubs and wore nothing but a loincloth.
Twilight couldn't help but wince at the advantage the diamond dogs had in both equipment and numbers. It goes without saying that more than a few minions would likely perish in the ensuing fight even if she helped. She felt physically fine, but her magic stores were getting worn out even with her boost in power.

Fortunately, Rarity's magic felt fine once the magic suppressant ring was removed. She stepped forward with a haughty smirk befitting her noble-esque mannerism. "If I may dearie, allow me!" Her horn lit up and across the charging dogs, their armor and clothing glowed with her magic, surprising the dogs who foolishly looked down at their now glowing clothing.

*YOINK*

Now they were naked. The now barren mutts yelped in shock as they were sent flying through the air due to Rarity's telekinesis, the few who could look up felt fear grip their hearts as they looked at their now smirking enemy.
What was once their clothes and armor was given to the minions, who cheered at their freshly stolen clothes and armor. With a savage grin, Twilight shouted with all her heart! "Charge!" Twilight bellowed out in a shockingly deep tone that startled Rarity and invigorated her minions who charged into battle, eager to please their Overlord!

It was a one-sided massacre, the dogs struggled in vain to repel the minions, but with the sheer ferocity at which the brown minions battled paired with their stolen gear, all it amounted to in the end was all the diamond dogs laying dead and Gnarl clapping his claws with approval. "Ah, the old grab and stab! It is good to see that your friends aren't all goodie-goodie mi'lord!" Gnarl praised as Rarity chuckled awkwardly.

Third/First person Pov: Rarity.

One of the weirder things Rarity learned in her brief talk with Twilight before they rushed to save the rest of the town, was that Twilight was now an "Overlord" not a princess anymore. Well, technically she was still a princess, but according to Gnarl, Overlord was better than princess, but that wasn't the weird bit, but rather that Twilight was evil now.
Rarity must say, she doubted the sentiment. Twilight might be a little more...violent, so to speak. But she would hardly call Twilight evil! If she was, she doubted that Twilight would have bothered with freeing her or anyone else from their chains.
To Gnarl and the minions, however, Twilight was their "new master of all evil" and "scion of darkness". Rarity found the whole thing a little cute, seeing the minions cheer as Gnarl proclaimed Twilight's titles.

Still, she'll keep an eye on Twilight, though she's confident her friend won't do truly dastardly things!

At least...she hopes so...

Third/First person Pov: Overlord Twilight Sparkle.

As the new Overlord approached Suger Cube Corner. Three things happened in rapid succession.
The first was an ear-piercing squeal, (which Twilight was sure broke whatever surviving windows there were). The second thing was her minions being scattered like bowling pins. And the final thing was her receiving the most powerful tackle/hug she's ever experienced.
If it weren't for her new height and armor she was reasonably sure she would've been sent sprawling on her back.
"OH MY GOSH TWILIGHT YOUR BACK!!!!" Pinkie shouted at such speed and with such joy that Twilight barely made out what Pinkie said and made Gnarl vomit on the spot!

"I MISSED YOU I MISSED YOU I MISSED YOU!" Pinkie blabbered out as she bounced at such speeds that Twilight if she didn't know Pinkie would've been surprised that Pinkie hadn't made a pony-shaped hole in the ground.
"WHERE HAVE YOU BEEN?! WHO ARE YOUR NEW FRIENDS?! WHY DIDN'T I KNOW ABOUT THEM!? TELL ME TELL ME!!!" At that point, the Overlord finally jammed her hoof into Pinkies mouth.
"Calm down Pinkie!" Twilight sternly yet kindly said as she stared the element of laughter in the eyes, Pinkie nodded but still vibrated on the spot.

With a sigh, Twilight smiled at her hyperactive, party-loving friend "Ok, come here" She removed her hoof and let her pink friend hug her. Unlike before, this one was much gentler but the mare still vibrated with excitement, Twilight returned the gesture before trying to remove herself.
"Pinkie..." Twilight said in an annoyed tone as her friend refused to remove herself, they needed to save the rest of Ponyville! "We missed you..." The poofy main of Pinkie flattening a little making Twilight sigh. Before smiling, "I missed you too Pinkie." She let the hug go on till Pinkie was finally ready to let go, Gnarl said letting such things happen in public was bad for her evil image, but at the moment. She couldn't bring herself to care what the old minion said. Pinkie was one of her best friends, and that's that!

She looked around as her cheery friend hugged her like she was about to vanish forever. Her minions were celebrating their victory, taking the opportunity to eat the sugary treats that Pinkie had been using as ammo, which they seemed to enjoy! Some of them went about looting the diamond dogs further, bringing her life force which she collected with her free hoof.
Others decided to torment the diamond dogs left knocked out by Pinkies party cannon. Playing demented little games like wack-the-dog! In which the minions tied up a bunch of diamond dogs and whacked whichever one woke up! Others included pin-the-tail on the dog (blood included!) and one game was just them chasing a diamond dog up a tree, lamp post, or whatever was high ground and trying to stab at them like a dog trying to get a cat in a tree!

Twilight couldn't help but release a dark laugh as she found herself enjoying the minion antics.

"Wowie Twilight that's a good evil laugh! But it should be more like a MWAHAHA!!! Evil laugh!" Pinkie said suddenly, surprising the Overlord who looked to her side and saw Pinkie bouncing in place with a happy grin.

When did she let go?!?

'Wait, why am I questioning that? It's Pinkie Pie...' Twilight shook her head exasperated as she stared at the cheerful party pony.

The ponies Pinkie had been protecting slowly peeked out, which included Mr. and Miss's. Cake. Cheered when they saw that the diamond dogs besieging the bakery had been defeated, though they made sure to cover the eyes of any foals trying to peak out themselves. Foals did not have any business in seeing such carnage.

Though speaking of said carnage.

It was at that point that Twilight noticed the dead diamond dogs had what looked like black clouds coming out of their bodies, some of the bodies even vanishing outright!
"I see you've taken notice of those black clouds rising from the dead diamond dogs, your Ladyship. That is called evil energy. It gathers in all us evil creatures. You will learn more of it in time, master." Gnarl explained with a sinister grin. Twilight nodded and looked at the vanishing carcasses one last time, yet more questions for her evergrowing pile...

Third/First person Pov: Applejack

"HEEYAH!" With a mighty buck, she sent a pair of diamond dogs flying into their own ranks, scattering them like leaves to the wind. Leaving them easy pickings for the dive-bombing pegasi.

She growled as she looked around. It had been two hours since this blasted raid started, and from here, she could see the smoke coming from Ponyville as the dogs set it ablaze.
The pegasai did their darndest to try and keep the flames at bay using rainclouds, but the dogs were an especially nasty sort, whenever a fire control team tried to stop the flames. Arrows, rocks, and whatever a dog had in hand would be shot/thrown at them. And the diamond dogs didn't discriminate with their fires, as she saw part of her family's orchard burn...

Applejack is not the hateful type, not in the slightest, but at the moment, she hated diamond dogs! A LOT!

"Applejack look out!" She spun quickly to see Rainbow Dash drive her hooves into a Diamond dog's face, knocking the mutt out cold. The element of loyalty stared down at the dog angrily before turning to her with an ecstatic expression!
Applejack must say, but this is the happiest she's seen the rainbow-maned pony in a long while. "I HAVE AWESOME NEWS! AND GOOD NEWS! WHICH DO YOU WANT FIRST?!" She blinked. Awesome news and good news? "Uh, what's the difference?" At that, Rainbow scoffed and said, "Duh! The awesome news is AWESOME!" The eager grin returned, and it was about time she finally noticed something.

The dogs were fleeing.

What the? Did they finally give up? Had these hard hours of fighting finally paid off?!

"Oh ho oh! Here comes the awesome AJ!" Rainbow Dash grabbed her head and turned it to where the dogs were running towards. The sounds of blades clashing each other echoed from the hill below, complete with mad giggling noises from a certain pink pony, but also the giggling and laughter of a ton of voices she did not recognize in the slightest.
Suddenly a bright purple beam of magic shot through the air! Followed by the terrified yelps of diamond dogs who began to run back towards them! The dogs had a look of utter terror on their faces as they ran toward the Applejack and Rainbow Dash.

The two ponies got ready to fight, only to watch as the diamond dogs literally flung themselves at their hooves and began to beg, "Please help us! We'ze sorry we attack you! JUST PLEASE STOP DAT MONSTER!!" Applejack looked down surprised. While Rainbow Dash looked down smugly as the few remaining dogs begged for mercy.
"Applejack! Rainbow! I'm I seein' what I think I'm seein'?" Granny Smith called out. The old mare was wearing her soldier helmet, and she, along with the rest of the Apple family, could only stare in shock. What happened to these dogs?! What monster are they talking about?!

As if to answer them, a Diamond dog suddenly crash-landed before Applejack!

"And here comes the awesome!" Rainbow with all the eagerness of a filly being told to go crazy in a candy shop!
And the surrendering diamond dogs screamed in a tone more befitting a filly.
Applejack watched as this armored alicorn burst over the hill, their wings spread out, using the sun to cast their shadow over the remaining dogs.

The dogs still fighting began to break and flee either towards the barn or into the orchard. Those fleeing to the barn soon joined their cowering kin. Those who ran into the orchard…well the screams Applejack heard were enough of an answer.
“Strike them down!” The Alicorn shouted and Applejack watched as a horde of brown creatures charged up the hill and slaughtered whatever dogs remained fighting before rushing toward them!

Applejack got ready to fight but instead watched the creatures stop before her and just…stood there. They had dumb, eager looks on their faces as they looked at the cowering dogs behind them.

“Applejack! You're ok!” What the-
Applejack watched the Alicorn. No…Twilight. Land with a heavy thump and the now larger Alicorn stare at her happily.

“Twilight…is that really you?” She couldn’t help but question, but she knew with every speck of her soul that her friend had returned!

Third/first person Pov: Discord.

‘Interesting…very interesting.’The embodiment of chaos mused as he spied on the new Overlord hugging it out with Applejack, “Oh gnarl my evil little friend you have your work cut out for you…” Discord cackled as his eyes snapped back into his head.
“What was that discord?” Fluttershys quiet voice questioned as she poured a diamond dog grunt some more tea.
“Oh nothing my dear, just watching some old pals.” Discord turned back to the impromptu tea party of diamond dog grunts and animals.

Originally, he turned them all into balloons, but listening to their pleas and whining, Fluttershy asked him to turn them back to normal. He huffed and noted he should’ve made them silent, but he couldn’t refuse Fluttershy.

At least he got to keep one authentic diamond dog balloon in the form of their captain. Said captain, squeaky his voice may be, was still making threats at him, Fluttershy, and of course, the pack that ditched him to get a better alternative than being balloons.

When the raid started, these dogs were sent here in hopes of acquiring fresh meat for their clan. Thinking these animals were protected only by a singular, helpless pony.

Discord will forever cherish their surprised faces when he popped out of thin air.

Fluttershy wanted to rush to town and see if she could help, but Discord knew she would just be captured. Besides, he saw and knew exactly how this raid would end. He felt that ancient power awaken and knew who now bore the title of Overlord.
‘I wonder if sunbutts noticed yet?’ He can’t wait to see Celestia's reaction to her student becoming the champion of evil!

Third/First person Pov: A diamond dog named Digger.

“Would like some more tea Digger?” The shy pony offered to one of the grunts, a more grizzled member if his scars were anything to write about.

"Thank ya kindly Fluttershy." The senior grunt said as he looked around. Things had taken quite a turn when he and his squad went to plunder this lone cottage for fresh meat. One second they were balloons, a little bit later, the kindness pony Digger ever met, convinced that draconequus to let them go and now they were having a tea party, their would-be prey acting as guests and waiters.

Well...save for their "captain" who was still shouting angrily in a high-pitched voice, promising retribution and pain when he got free. He cast a glance toward the mish-matched devil who waved cheekily at him.

'Good luck with that.' Casting a look back to his balloon captain before drinking some of the freshly poured tea. He must confess, he feels bad about the raid, it was nothing personal! You can't just say no to the boss!

...Okay, you can, but it will likely result in your head being removed unless the boss really likes your idea. But even then...

Just as he took a sip of his tea, that mish-matched abomination of a creature teleported in front of him! Spilling his tea in the process!
"hehehe, your rude thoughts aside my houndish friend, I advise you to get ready, for you have company and your captain won't be a very good representative" Before he could question the chaotic spirit, he teleported again.
Digger blinked as he looked down at the spilled tea, he looked around and saw his pack looking at him confused, a similar sentiment that was shared by the animals it looks like.

Who on Equis was this "company" Discord mentioned?

Third/First person Pov: Gnarl.

"Well if it isn't my old drinking buddy!" The old minion said as he stepped off to the side to see his old "friend."

"My my it's been too long Gnarl! Tell me! Is that a new wrinkle on that potato-shaped head of yours?" The draconequus said, pressing a thumb against Gnarl's head, making the old minion's face scrunch downward, making it look like he indeed had more wrinkles than he actually had.

"I'm surprised this place isn't a wasteland of flying pigs and chocolate rain! What are you up to?" The old minion cast Equestria's sole draconequus a suspicious look, the old minion knew Discord was much more clever than he let on. And if the draconequus had plans to be supreme evil, he had another thing coming!

"Oh don't you worry your wrinkly head Gnarl, I have no nefarious plans here my friend! For you see! I'm a reformed citizen of Equestria!" He said with an exaggerated bow. At that, Gnarl barked out a laugh, "HA! You? Reformed! That will be the day! Tell me Discord, what's sunbutt holding over your head to make you kiss her hooves and polish her royal buttocks?" At that, Discord frowned before smirking.

"Why nothing at all, my glorified walnut, I simply learned a thing or two about friendship from your...*snort* "Evil" Overlord over there and her friends," he said with a smirk as he looked over at Twilight, who was currently questioning the diamond dogs Fluttershy talked down into surrendering.

"Oi! Don't besmirch her evilness! Less you wish for a personalized version of the great draconequus war!" Gnarl stated in which Discord simply laughed, "I must say! I admire your faith in your new "dark scion" and how she'll be the next supreme evil!" Discord then leaned close to Gnarl. "I wish you luck Gnarl, your dark Overlord may just end up the Overlord of friendship and goody-two-shoes." Discord chuckled and smirked as Gnarl visibly gagged at the thought.

Glaring up at the spirit of disharmony, Gnarl gave his own smirk "You wish you modern art masterpiece! The evil that lies in her blood is kicking into gear and she's already proved adept at slaughter and unleashing mayhem!" Discord merely grins. "Whatever helps you sleep Gnarl..." The chaos lord said before floating away to the disgustingly cutesy cottage.

Gnarl rolls his eyes before turning back to his master. He grinned as she rallied her minions, with her friends and new subjects secured, it was time to march on the crystalline castle! Where the largest force of the remaining diamond dogs laid siege.

If its origins were true, it was a little gift from the Tree of Harmony meant for Twilight to live in after her old home was blown up in the fight between her and Tirek. Which in turn meant a large source of magical energy! Once she's inside and imbues her Overlording magic in it. It will be enough magic to give the netherworld the kick in the pants it needs to accept
her as the new Overlord!

As he made his way to his master, he thought back on his little exchange with the chaos lord. He scoffed, before letting loose a dark chuckle and thought back to one of the Overlords of the past.

"Heroes seldom know how close to evil they really are..."

Author's Note

And third chapter is done! I apologize for a lack of a boss...well, mini-boss fight, but as I was writing, I felt it wouldn't exactly blend well towards the end, so I decided to have Twilight do battle with the raid captain next chapter, which will be shorter than this one but it will be filled with action and an evil smiting!

We will also see what the princesses are up too and learn little bits of the various lesser evils causing trouble for Equestria.

Also I'm liking the comments from the previous chapter! The Kelpies will based on equal parts mixture of their mythical IRL counterparts and MLP's kelpies, with custom things here and there.

I saw some of you mention the idea of Caribou appearing and I didn't initially have plans for them, this isn't a Fall of Equestria fic after all and there isn't any anthros to be found here.

But after thinking on it for a while, I realized they could make for a good northern foe with an alliance to a certain dark unicorn, his name is up there in the tags after all.

It must be noted that they are quite different than the sex obsessed pieces of manure they are normally portrayed as, if that was the case, the sex tag would be up there, here they are just asshole raiders storming down north (At least till Twilights wraps them in her iron-hoof) but Caribou and Kelpies won't appear for a good bit, for now this the "Diamond dog arc" if you will, Twilight learning the ropes of being an evil Overlord and slowly dominating Equestria under a proper evil!

Also here is a map I'm using, for Equestria itself, you can ignore the other parts of the map for now. The only real changes is that the north part of the map will be expanded for the Caribou, most of the cities shown won't be a thing, and a certain city in the swamps from Overlord 1 will make its home in froggy bottom bog.
Enjoy lads!

(PS, I hope I did Twilight reuniting with her friends again well, save for Fluttershy and Rainbow, who I did off-screen, personally felt I perhaps did better but wasn't sure how exactly, still I hope you enjoyed it and will see you next time)
