The Beast lunges forward with incredible force. Chrysalis vanishes in a green flash a split second before impact causing Sam to crash through the wall. Chrysalis reappeared on the outside of the wall as it collapsed behind her. As Sam turned around to face her, she was horrified to see he was completely unscathed. This new body of his just smashed through a 14" thick stone wall like it was glass, and he intended to use it for one thing...
"Chrysalis!!" His booming voice managed to strike fear into the queen. "Let me assure you this: At least one of us is going to perish here and now! And I'm not about to let you escape... Even at the cost of my own life, I will end yours!!" He charges at her like an angry gorilla.
Chrysalis tried to stifle his approach by firing a beam of magic at his chest. Other than the impact leaving a black dusty mark, the shot didn't even make him flinch. She wasn't able to react fast enough to escape from Sam's tight grip on her shoulders.
He lifted her above his head, back-flipped, and kicked her into the air behind him in a large arc. She was stunned by the hit, flying threw the air like a ragdoll. Sam's incredible strength allowed him to jump to an impossible height and distance; he quickly met back up with the queen. He would've slammed her back into the ground below hadn't a drone intercepted her trajectory and took the full force of the blow. It disintegrated upon impact.
Chrysalis was caught and teleported to a safer area of the cave behind the shambling castle by three more drones. Acting as a hive-mind; they all knew where the queen was, where to take her, and to touch their horns to hers to sacrifice themselves to heal her. Without her to spawn more drones, the Changelings will effectively go extinct, and Sam knew this. He was hoping to eliminate them all by taking her out so all of Equestria wouldn't have to deal with them anymore.
Transforming into glowing green energy, the drones channeled themselves into their queen's horn. Chrysalis regained full consciousness and lifted her head just in time to duck it back down. She narrowly avoided Sam's massive foreleg slamming into her face. He slid several meter's away from her, leaving grooves in the ground with his back hooves. He turns back to the queen with that same devious expression.
As Chrysalis got to her hooves to fly away, half her drone army blotted out the light from the crystals overhead and dove toward Sam.
Sam's grin grew wider as he stared up at the drones. "Watch closely! A massacre like this has never been seen before..."
With the Beast becoming completely engulfed by the drones, Chrysalis took this as a perfect time to escape. She started to fly away, but couldn't help but look back to see her drones dying one-by-one; sometimes two or three at once. She could barely see the pale pink mass in the center, but she could easily notice the black smoke emitting from around it.
Sam was not slowed down by his bulk whatsoever. He followed up each of his movements with a new strike, making sure to kill at least one Changeling every time by sheer blunt force, slamming them into each other or the ground, or ripping limbs off.
After nearly a minute, the army finally backed off, they were starting to get the idea that they were not going to be able to stop him. Sam stood triumphant with numerous fang and scratch marks all over his body, all of them drawing negligible amounts of blood.
Chrysalis was baffled by this display: immense fear from the fact that this unstoppable behemoth is dead-focused on killing her specifically, and anger that her subjects are retreating. "What are you ingrates doing?! Attack!!" Most of them ignore their leader and decide to stay high up in the air where they're relatively safe.
However, one drone decided to kamikaze Sam and go straight for his neck. Sam treated it like it wasn't even there for the first few seconds. Soon, after desperately trying to drain him, the drone gets its hind legs caught tight by Sam's hulking front hooves. Sam holds the drone upside-down, and with a swift motion, vertically rips the drone into two pieces. The halves promptly evapourated. This action caused Chrysalis to feel a chill throughout her entire exoskeleton.
Sam cackles like a maniac at the cruel display. "Don't think I won't hesitate to do the same to you!"
Chrysalis shivers for a moment before barking out orders. "We will go extinct if he catches me!!! Either die to him or die to me!! Give me time to escape, you little rats!!" For the sake of their race's existence, the rest of the drones in the valley rush Sam as she makes a break for the exit.
Sam chases after her, plowing through every drone that approached him. He made one leap to get on top of the shambling castle, and another to grab onto Chrysalis' leg. He tossed her back towards the castle.
Chrysalis flies through a hole in the roof and conveniently onto her bed. She scrambles off in a dazed panic, just in time to avoid Sam landing on top of her.
The impact caused him to destroy the entire bed and the ground it rested on. He fell to the main foyer with the storey above him falling apart bit by bit in an ever-expanding hole. Chrysalis was breathing heavily as she falls through the hole; not enough energy to try to fly away.
More drones dive toward Sam who was standing neatly on his hind legs. He shatters the several dozen of them with single punches and slamming them to the ground.
One drone was able to get to the queen in time to give itself as a sacrifice. Chrysalis was about to fly away when Sam sends the last drone of his group careening into her. She hits a wall and shoves the disoriented drone towards Sam, who was calmly making his way toward her. His tremendous stature loomed over Chrysalis as she stood up and stayed backed up to the wall. The torch on the pillar behind him cast a shadow that nearly engulfed her. He picked up the weakened drone with one hoof, eyes locked with the queen's. In a horrifying display, he bites into its neck and rips off the head. He then closes the gap between him and Chrysalis.
Chrysalis saw nowhere to go. She was too frightened to focus on a teleportation spell, and she didn't have enough time to turn around and blast a hole in the wall behind her. She quivered from fear and pain from her bruises. "M-m... Mercy!" She wasn't thinking when giving what could have been her final words. She and Samuyl both immediately noticed the absurdity of such a proposition.
Sam was within leg's reach when he abruptly grabs her by the mug and lifts her up. He spouts, "What's mercy?" and throws Chrysalis across the room. As she was landing and regaining balance in the opposite corner, Sam hugs a nearby pillar that was still intact, and lifts it out of its foundation.
Chrysalis finally had an accurate scope of how strong Sam really had become. She was frozen in disbelief that he was only now struggling to use his new-found power by lifting a marble pillar that was easily over 200 times a pony's usual weight.
In a wide stride, Sam swings it around to knock out the rest of the pillars, causing the castle to completely crumble away. He throws the pillar toward Chrysalis in the back-swing.
She was barely able to hop over the pillar, leaving it to utterly destroy the last wall of the castle. With the castle now completely leveled, all the drones had a clear shot to attack Sam from all angles. Chrysalis adds to the assault by levitating large chunks of rubble and sending them flying toward Sam, who wrecked each one of them by letting them crash into his back, front legs, or other Changelings. None of the impacts did anything to slow him down.
When Sam noticed Chrysalis starting to fly toward the exit of the valley, he breaks from his position and pursuits her. He quickly picks up a small piece of debris and tosses it with great precision.
The rock hits the queen in one of her thighs. She shouts in pain and ceases flying. The pain was too sharp to allow her to continue her escape.
Meanwhile, Sam was being buried by the remaining Changelings. He hasn't grown the least bit tired or weak, and he wasn't about to halt his slaughter just yet. In a quick spinning motion, he flings all the drones away from him. He promptly lets out another terrifying roar that also had the same reverberating soundwaves. Many of the drones that were too close to him imploded; others backed away. The roar caused many more rocks than before to fall from the ceiling of the cave. Some of the crystals started to come loose.
Many of the falling rocks crushed a considerable amount of drones as they fell. In those 12 seconds, Sam managed to reduce the already dwindling Changeling population down to a couple hundred.
When the roar stopped, Chrysalis noticed that she barely missed being flattened by the falling rocks. She was consumed with fear to see how few drones she had left. One of which, of course, spending its final moments coming to her aid. With what could likely be her last heal, she uses this new energy to make a last-ditch effort straight up to the exit.
Sam paused ripping off the limbs of some of the last drones before making a huge leap to catch up with the fleeing queen. He almost sandwiches her into the wall, as she finally makes it to the tunnel leading to outside. Sam uses the strength in his front legs to propel himself up the wall and toward the exit. He climbs into the flat tunnel and lunges toward Chrysalis, easily catching up to her and tackling her to the ground.
He stands up with Chrysalis in a nearly bone-shattering hold. She could only flail her hind legs and head around in pain as she screams for her drones to help her. "Yes. That's it. Cry! I want to hear an ancient god-like being screaming in agony! You know this: I am your reaper! I am going to destroy you and rid this world of your filth!!" He shouts at her before giving a quick squeeze to immobilize her. Chrysalis was gasping and whimpering.
Sam threw her back out of the tunnel and on top of a pile of rubble that was once her castle. He emerges from the exit to finish his deed. But he figured for good measure, he would focus on the drones that were trying to heal her; leaving her barely conscious, writhing in pain.
As Chrysalis' vision started to blur up, she watched Sam jump all around her, killing every drone that tried to come near her. She couldn't hear Sam's laughs or grunts, or the squeals of her subjects, only her own slowing heartbeat. She lost all feeling in her body and soon slipped into a coma as the last of drones are slaughtered all around her.
