Revenge Through Creation
It couldn't have felt more crushed in its little cocoon. The cries of its mother to awaken resounded in its mind, coaxing it from birth's slumber. It could feel its full length appendages follow its every command. Mother was excited, it could tell. It was new, in more ways than one. A monstrosity within its own disgusting hive. The changeling broke free from the flashy shell.
Chrysalis couldn't have been more pleased. Every creature had a unique flavor to it, and it was her species specialty to mimic it, creating multiple forms of changelings to accommodate this need. Changelings for ponies, dragons, minotaurs, and almost every living thing in this world.
And now she had discovered a new creature , and she had what she needed in order to copy its exact genetics. A new base form was needed, and here it was, fresh from the cocoon. She was scared of it at first, as it emerged, but soon found the humor of her finding fear in her own child, let alone those to face it.
Its massive form towered over her, its black carapace resembling its origins almost identically. As with her command, Chrysalis's new progeny made its way through the hive. The being took in all of the details.
As they made there way outside, it got its first glimpse of its home. The dirt beneath it not unlike skin, the mountain behind them made of sickening fleshy bone. Trees of marrow secreting a viscous mucus the dragon Changelings found as adequate nourishment. The new horror made its way to the mutated tree with a rather gentle gait. Chrysalis's other offspring looked at it with indifferent eyes, refusing to move. She wanted to see what her new abomination could do.
Her new little Changeling tried to reason with the others, requesting a spot to feed. Of course, the others refused. Enraged, it jumped with incredible agility on top of the dragon form, piercing through its carapace and stabbing its internal organs. The blood of her child seemed to rain from above her, and she couldn't be any more proud. As the dragon Changeling's corpse fell upon the fleshy earth, the new prodigy feasted upon the tree.
Chrysalis had done a better job than she had hoped, mimicking this new species. It even inheriting their murderous and violent tendencies, regardless of the relationship. She summoned the creature back over to her for a closer inspection.
A swarm of her pony Changelings surrounded it. The New Beast looked at them in concern, confused as to what would transpire. Its siblings analyzed it with critical eyes, most fearful of its presence and its alien structure. This new form walked over to a single Changeling, poking at its horn in confusion. Chrysalis noticed the New Beast was the first Changeling without one. A shame, since it would not be able to perform proper magic. Then again, neither could its origin. From what she had seen, this creature was deadly regardless. Exactly what she needed.
The Changeling it was studying changed form to a white unicorn, the one Chrysalis knew as Shining Armor. Just as she had commanded. The New Beast grew agitated at the sight of the pony, quickly reaching down, and snapped its neck. Such a sight surprised the Queen. The others were horrified, quickly charging to subdue their fellow family member. The New Beast roared as it charged its siblings. Its new appendages, long than a dragon's wing and sharper than its claws, slashed about the crowd. Its ferocity was unmatched, as the sounds of evisceration flooded the air. Chrysalis's nose filled with the delicious scent of her children's blood.
She grew more and more satisfied with each kill. As she watched a fraction of her hive get wiped out, Chrysalis began to realize the true nature of what she had created.
If these creatures were really this powerful, then creating the New Beast was the best course of action.
As the carnage soon ended, Chrysalis's progeny stood victorious, her other children all beheaded. It made its way over to her, also looking upon her horn in jealousy. Chrysalis soothed her child, assuring it didn't need one with its skills and strength. It's misshapen jaw began to move, as it spoke its first words.
“...W-Wh-Where is h-he?” It said, its voice as crooked and rough as jagged rock.
Chrysalis grinned, pleased that it's cognition was still intact, despite the rapid birthing. “He is far away. In the city of Canterlot, I believe.”
The New Beast rolled the word around his tongue and his mind. Its mind was flooded with alien memories. The Hive mind connecting its conscious to the greater whole.
It saw a city, on the side of a mountain. A pristine and ultimately unscathed piece of land. Disgustingly clean and horrifically untainted. The regal forms of what it learned to be the Princesses stood atop this mountain with such pretentious pride and arrogance. It wanted nothing more, than to destroy the city, and rid the world of him.
“I m-must find him,” It confirmed.
“Yes, you must. First, I want you to transform into his likeliness.” Chrysalis licked her lips in anticipation, as the New Beast graciously accepted the order.
A quick green flash enveloped the creature. It's carapace becoming replaced with an almost hairless coat. The claws tips becoming rounded. Flesh melted onto its face, as the skin coalesced in the exact image her memory had of this being.
Much like a scaleless dragon, she considered. The New Beast towered over her form. Were it not for her matriarchy, it would have been a most terrifying sight.
This being her child mirrored had completely ruined her plans for invasion on Canterlot. Were it not for him, Celestia would have perished.
Her rage radiated throughout the fleshy earth, as her children grew restless, demanding action. The New Beast in front of her grew the most agitated.
It growled. “Let me kill him.”
“Then go. Destroy this human.”
