King Sombra returns to Galloping Gorge Caves after gathering many materials from the flea market. He gives a lot of metallic parts to Storm King. Different engines and batteries as well.
"So, let me work my magic," Storm King cracks his knuckles. Using the material he has, Storm King forges a Techno-Soldier within an hour. It mirrors the body of Midnight Sparkle and himself. The helmet and face is skeletal feature. "So, how would the magic work, Midnight Sparkle?"
Midnight Sparkle walks up to the six-foot-tall Techno-Soldier. "Like this," Midnight Sparkle's horn glows green and gives life to the Techno-Soldier.
The Techno-Soldier eyes are green with red pupils. The armor is blue and purple from head to toe. The Techno-Soldier wields a magic sword on one hand. The other hand can scan a creature's power and create a counter shield to repel any attacks. Another feature the Techno-Soldier has is the ability to fly without wings.
"Now, kneel before your Empress," Midnight Sparkle commands the Techno-Soldier. The Techno-Soldier kneels to Midnight Sparkle. "When we're near the mirror pool, I'll grant the Techno-Soldier magic power I absorbed from the Tree of Harmony and Elements of Harmony. Then infuse it with my Demon Curse. Each of us will command a legion when battling any creature or nation that oppose us."
"Day is rising," Storm King said.
"We'll wait for the night. When most creatures are asleep."
Fifteen hours later. It's 10:30 at night. Midnight Sparkle takes flight while levitating the Techno-Soldier. Cozy Glow and Tirek take flight as well.
"Hey, I can't fly!" Storm King shouts.
"You're coming with me," King Sombra drags Storm King into his shadow and travel at fast speed.
An hour after flying, Demon Tail arrives at the location of the mirror pool. Cozy Glow said this is a pile of rocks. Midnight's hand glows red and shatters the rock pile. Demon Tail enters the hole and sees the mirror pool.
"Here we are. This pool will produce our numbers, and in a day's time, we'll have an army that exceeds the population of every nation. Soldier, recite the enchantment."
"And into his own reflection, he stared. Yearning for one whose reflection he shared. And solemnly sweared not to be scared. At the prospect of being doubly mare," The Techno-Soldier recites and enters the mirror pool. Now there are two Techno-Soldiers.
"Soldiers, recite the chant," Midnight commands.
"Oh great, this is going to be an earache," Lord Tirek is not thrilled with the reciting enchantment the soldiers will speak for days on end.
"King Sombra, survey Ponyville for any news. We're going to be here for a while."
"Understood, Midnight," Sombra goes into his shadow and leaves the mirror pool.
"Lucky," Storm King sits down.
"While the Techno-Soldiers produce themselves, hone your abilities than sit around and wait."
"Fine," Lord Tirek gets up. "It's better than listening to the same garbage over and over."
"I'm coming with you, best friend," Cozy follows Lord Tirek.
"So, what does this staff do?" Storm King asks Midnight Sparkle.
"You can create storms; Lightning, hail, snow, rain, thunder, tornadoes, hurricanes. Anything related to the weather, that staff has control of it. You are the Storm King, so it's right for you."
"Hah! Better than that other staff I was planning on using!" Storm King goes outside to test his new staff, and any wanderers that come will be target practice.
It's been two days since King Sombra stepped out of the mirror pool caves. He's been hiding in every shadow, away from the clones of Discord. He sees familiar faces from the Crystal Empire and pays close attention.
"I can't believe Rarity went after Spike like that," Rainbow speaks with Applejack.
"I know. Rarity went bonkers on the baby dragon and injured Terax. I wonder if Twilight will get that restraining order despite Rarity being in the ward."
"Only time will tell, Applejack. Need some help at the farm?"
"Yes, Applejack. Apple Bloom is with her friends doing private friendship tutoring while the School of Friendship remains suspended."
"Another Twilight and Spike in the world. Replacements. Midnight Sparkle will be enlightened about the discovery of this."
King Sombra waits until the two trots to Sweet Apple Acres. He travels back to the mirror pool caves. Within the hour, the mirror pool caves become a bit overcrowded. Thousands of Techno-Magic-Soldiers are in line, waiting for any commands.
"I feel like a King again!" Storm King laughs in triumph with his army in place.
"Midnight Sparkle," Sombra rises from the shadows in front of her.
"What is it, King Sombra?"
King Sombra smirks. "There's another Twilight Sparkle and Spike within the world."
Midnight Sparkle balls her fists. "So, they want to replace me? Start anew?" Midnight feels conflicted about being replaced by her friends and family. "No matter, I'll corrupt their minds and make them kill the replaceable. As for this Spike, if I fail to bring Spike the Fairy, I'll start anew with this Spike. All will be right accordingly."
"How would you fail, Midnight? It seems your doubting yourself?" King Sombra sneers.
"I've underestimated Spike the Fairy's friends and their magic power," Midnight Sparkle reminds herself about her defeat by the hands of Erza and her Fairy Rage Armor. "I will kill Erza Scarlet a second time. I will mount her head in my castle."
"So, where are we Storming into?" Storm King asks.
"The Crystal Empire. We need to take out the Crystal Heart and relinquish the hope the Crystal Ponies have."
"Time to install fear on my kingdom once more," King Sombra relishes the possible faces of his subjects in chains.
"How are we going to transport these soldiers?" Cozy Glow asks Midnight Sparkle.
"We're going to hijack a train. Any creature inside belongs to Lord Tirek to devour."
"Perfect," Lord Tirek hopes the train is crowded with ponies of all kinds.
"So, the Crystal Heart. What happens if we destroy it?" Storm King asks.
"It will release a storm so powerful; the Crystal Empire will be engraved in snow," King Sombra explains.
"Storm! Let my staff absorb its uncontrollable weather phenomenon! I've been practicing the magics with my new staff. I can absorb the weather and control it to my every whim."
"Perfect, then the Crystal Ponies will have no hope left," Midnight Sparkle said.
"After I harness the magic of the Crystal Heart, it'll destroy it. The Crystal Ponies need to know how strong their King is!"
"I can't wait to play with those strong Yaks!" Cozy Glow imagines doing all sorts of fun stuff with them.
"In a few hours, they won't know what's coming."
