Cut Throat's Battle Form
"You want us to do what?!", Pine exclaims in shock causing Kaiser to cover him mouth and shush him.
"Quiet, you fool!", Kaiser whispers. "I cannot be seen with you, remember?"
"Sorry, but this plan is crazy.", Pine said. "You want us to siphon off hatred and feed it to Chrysalis?!"
"Of course, it'll be the fastest way for my mother to evolve to her battle form.", Kaiser said.
"And it'll also increase the chance to her to go into her hunger rampage, since hate is the opposite of love.", Pine said.
"Don't you think I know that?", Kaiser said. "I would never do something, unless I have the means to maintain control."
"That's true, you're not the type to do something crazy unless you know what you're doing.", Pine said.
"As we speak Governor Court is slowly forming an anti-non-ponies group.", Kaiser said. "All to protect Equestria from danger."
"Why does this reminds me of some famous comic book series?", Pine said to himself as he listen.
"As you are aware the ponies of Equestria are nothing than creatures of happiness and joy.", Kaiser said. "But beep within their their cute exterior is their dark interior. A darkness they can only suppress, but not destroy for it is a part of them."
"So you want us to open up their darkness inside them, but how?", Pine asks.
"By granting them their greatest desire.", Kaiser said with an evil smile. "And who better than the enemies of the Elements of Harmony."
"To think all of that happened.", Twilight said sitting on her throne with the others after the whole ordeal with Blueblood.
"You sure you're alright, Twi?", Applebloom asks with concern seeing the returned group recovering from their injuries.
"Yeah, Blueblood put up a good fight even with Rainbow Power.", Twilight said.
"Although that's mostly because that was the first time you used it in actual battle, not to mention Blueblood temporarily achieving Alicorn form.", Assassin said.
"Where is Blueblood anyway?", Applebloom asks. "And the other three?"
"He choose not to return to Equestria believing that he's not ready to see Celestia.", Twilight said. "That and feeling guilty for what he did even thought he was manipulated. As for the other three, Sunset went back to the other world since she's been gone long enough, Moondancer went back to Canterlot and Trixie went back to her coach to recover."
"Well for the time being Elemental decided that me and Sterling should stick around.", Assassin said. "To keep an eye on things and mostly wanting Sterling to be with ponies of her age rather than following adults to dangerous adventures."
"Just when I thought we get a break after our last adventure this happens.", Rainbow Dash groans lying on her throne.
"The tension between the Changelings and Ponies have increased and not only that Chyrsalis is hurt.", Starlight said sadly.
Suddenly everypony in the room suddenly feel heavy and start to slowdown.
"What's going on?!", Trixie screams.
The Cutie Map glows and immediately negates the Heavy Acceleration effect restoring proper movement to the ponies.
"The caster must be close.", Assassin said hurrying out of the castle.
A Changeling casually walks past a group of Royal Guards chasing an escaped convict all affected by the Heavy Acceleration.
"Cut Throat.", the Changeling said standing before the fleeing earth pony. "I've been searching for people like you for a good source of hatred. Let's get you back to normal first."
The Changeling hands a jade crystal to the pony causing him to move normally within the Heavy Acceleration.
"W-what are you?!"
"You criminal exploits are magnificent!", the Changeling said. "They're extremely atrocious!"
"I am... magnificent?", Cut Throat asks in surprise before laughing. "That's the first time I've heard that."
"The Onyx Core can fuse us together.", the Changeling said. "When that happens, you and I will be one. We'll possess great power!"
"I'll just be arrested again anyway.", Cut Throat said getting up. "Alright! Let's do this!"
"Good! I've synchronized with you hatred!", the Changeling said entering the Onyx Core, which then spreads onto Cut Throat transforming him into a monster.
Cut Throat's Battle Form
"I've changed into a monster?", Cut Throat questions.
"I provide you my battle form, while you provide my the power source which in this case is hate.", the Changeling said within the body. "Together our powers easily surpass both Celestia and Luna combine plus the Onyx protects us from magic that'll affect us like Discord's.
"In other words offensive magic can still harm us.", Cut Throat said as he easily cuts a stone statue like butter with his halberd. "This is such awesome cutting power! Let's try it out on these guards!"
The guards scream and try to flee, but their body still remains slow, but before Cut Throat could get to them several spears pierce through his body. Aside from being painful, it did little to hinder him as Assassin jumps in and attack him with his sword.
"Who the hell are you?!", Cut Throat asks. "You're no guard!"
"Nope, just some pony passing through.", Assassin said before tossing a grenade at Cut Throat which explodes. The explosion broke Cut Throat's concentration resulting in the Heavy Acceleration to cancel out.
"You quiet good! Better than any of those useless guards!", Cut Throat said.
"He's a High Inquisitor from the Unknown.", the Changeling within him said. "His skills is a match for a hundred guards."
"Two voices? A fusion!", Assassin said in realization.
"I don't have time for you!", Cut Throat said. "I already have somepony in mind to target."
Cut Throat fires a blast to the ground creating a smokescreen giving him the chance to escape.
"Tch! He got away!", Assassin curse as the Heavy Acceleration effect wears off allowing the guard ponies to move normally, just as the Mane Six and Starlight arrives.
"Is everypony alright?", Twilight asks helping the guards up. The all respond with a nod.
"Well this is unexpected.", a red pony with black mane wearing a red leather jacket with grey fur on the neck of it said approaching the group. Assassin widen his eyes in horror upon seeing the man.
"Everypony get back! That pony is actually a Changeling, but not just any Changeling. He's Sleipnir!", Assassin exclaims causing the Mane Six the glare nervously at the disguised Changeling. This Changeling is the second son of the Empress and is one of the strongest or rather is the strongest of the Kings and Queens. "Why are you here?"
"I've come to avenge my sister. My siblings and many others see her useless, but I cherish her greatly.", Sleipnir said. "You could say the she's my favorite and you ponies nearly killed her."
"You've got it all wrong! These ponies saved her life and the ones who attacked are just extremists led by Amadeus Court.", Assassin said trying to ease the tension, knowing a fight against him is suicide.
"So that bastard Court's legacy lives on through his descendant. I knew I should've killed his entire family.", Sleipnir mutters in frustration.
"What?!", Twilight cries stepping up to him, but Assassin quickly restrains her. Starlight then walks up to Sleipnir.
"Tell me something.", Starlight said. "The Changelings and ponies have known each other for more than a thousand years ago. Why have there not been peace between the two until Thorax?"
"Although Thorax is now a traitor and you ponies are my enemies, Thorax is still family and you did took good care of him so I'll answer your question." Sleipnir said. "The peace between you ponies and Thorax's Hive was in actuality the second peace talk between Changelings and Ponies. The first however was a nightmare for the Changelings, especially Chrysalis."
"Chrysalis was involved?"
"I'll never forgive him, Argus Court! He's the worst. We Changelings have some morals, but that pony has none.", Sleipnir said. "I will never forget the heinous acts of torture he inflicted upon my kind."
The Mane Six are left appalled at this revelation.
"At that time, a Changeling went through the same metamorphosis as Thorax made a shocking announcement to the Empress.", Sleipnir starts. "That Changeling was Chrysalis' husband."
"You want to do what?!", the Empress exclaims in shock upon hearing that the Changeling said. "You want to make peace with the ponies?"
"Why now, Metamorph?", Sleipnir asks.
"For generations, we lost our very identities when we were treated as slaves and became what we are now.", Metamorph said.
"What we were made us weak and vulnerable to these other creatures.", the Empress said. "We became what we are now to defend ourselves."
"And what was once protecting ourselves became hatred to the other kind and thus our brutal conquest.", Metamorph said. "But now these creatures are not like those that once enslaved us. I believe we can now live in peace with the other creature and return to what we once were."
"It has been a long time since, mother.", Sleipnir said. "Perhaps we should give him a chance."
"Very well then Metamorph.", the Empress said. "If your are successful in making peace with one of the other creatures then we'll go along with your plan."
"Oh please, peace is a lie. It's just an excuse to lower your guard and be killed.", Miasma said. "Believe me, I've seen it happen everywhere during my days as an infiltrator."
"Unfortunately, Miasma was right.", Sleipnir said. "For about an year we received no word from Chrysalis, Metamorph and a few other Changelings sent as emissaries. Thus I was sent to see what happened and never have I've seen something so disgusting."
Chrysalis screams in pain as she falls to the ground being electrocuted. Argus Court laughs at Chrysalis' pain. Around the two are dissected bodies of Metamorph and other Changeligns.
"What's wrong, Changeling? Does it hurt?", Argus asks with a sadistic smile. Having heard the scream, Starswirl bursts into the room and is horrified at that he sees.
"What on Faust's name are you doing, Argus?!", Starswirl shouts as he helps Chrysalis up, but was horrified upon seeing her injuries and the dissected bodies of other Changelings. "I can't believe it... These Changelings are here to make peace and you do this?! They'll never trust us ponies again!"
"So what?! We won the Changeling War, meaning that they're lesser creatures compare to us. A peace between the two species would mean that we're equals.", Argus spat. "Plus this is a perfect chance to Equestria to learn more about the Changelings and their magic. It'll make Equestria even stronger and perhaps make it into the most powerful kingdom in the world. The other creatures will bow before us as their masters!"
"I've tolerated your questionable actions only because it was for the good Equestria, but this has crossed the line.", Starswirl said standing up. "My friendship with you ends today!"
"Hey, stop joking around. The only reason I remain in power is because of you! I'll be in trouble if you pull out now!"
"Shut up!", Starswirls roars in rage before storming off with Argus running after him. After the two leave Sleipnir cancels his invisibility spell and picks up the traumatized Chrysalis with his arms, picks up the other bodies with his magic and leaves."
"After that incident I swore in my heart that I would get back at all those who who wronged us! No... I swore in my heart that I would punish every creature!", Sleipnir cries in rage. "That is the main reason Chrysalis rejected your offer of friendship back then. She believed that you would to the same thing that Argus has done."
Argus transforms to his battle mode and grabs both Twilight and Starlight to the neck.
"However she started trusting you after you saved her from death's door, thus I'll give you this final chance. If you're able to heal her bleeding heart and successfully have her metamorph then perhaps there is hope for use Changelings to return to our old custom, but if you fail or she dies then I promise you that I'll make the ponies an extinct race. Do I make myself clear?"
"Crystal...", the alicorn and unicorn mare gasps as Sleipnir release his grip.
""I'll be watching you.", Sleipnir said before teleporting out of Equestria.
"We're doomed...", Rarity said.
