The large creature now known as a Leviathan approached Char, a volcanic and harsh planet that the Zerg call home. The Leviathan stopped and opened its mouth, showing the landscape and terrain to them all.
"I've never seen a place like this before... It's... Amazing... This is the Zerg home world?" Twilight asked, but Kerrigan shook her head.
"The Zerg use this planet as their primary base, and it looks like the Dominion's made themselves at home while I've been gone." Kerrigan answered.
"Is there more to this Leviathan? Should we explore a bit more?" Rainbow Dash asked, not quite ready to kill something for the first time.
"The Queen's chambers are not yet accessible, but you may visit the Evolution Pit. There the creature Abathur evolves and mutates the Swarm." Izhsa said, which prompted them to enter. One they got inside of the Evolution Pit they noticed several large green masses that moaned and squealed. However a large creature began to rise out of a hole in the Leviathan. It was green with four eyes, each one with a red pupil in the center. It used two large scythe like appendages to assist its rising, while another pair with large stingers poked out of the hole. It had four arms, the top one being smaller than the bottom, each arm ended with a three fingered hand that had very sharp claws. The creature placed its four hands together and looked at the seven that approached.
"What are you!?" Twilight asked in horror.
"Abathur. Evolve Swarm, spin strands and sequences. Served Overmind, then served Queen of Blades. Now serve her." Abathur pointed at Kerrigan who looked offended.
"I AM the Queen of Blades." Kerrigan said, but Abathur began to argue.
"Different. Examining genetic strands. Queen of Blades was efficient, ancient Zerg qualities. Minor Terran influence. Queen of Blades efficient. Can give it back. Better." Abathur said before reaching his hands towards Kerrigan whose eyes flashed yellow.
"Don't touch me!" She shouted, and Abathur swayed back in shock and fear, before regaining his calm stance.
"Can mutate Swarm from Evolution Pit. Changes not permanent, can change at anytime." Abathur said, motioning to the only Zerg creature in the room besides himself. It was a Zergling, short and vicious. It's claws were sharp and ready to kill, its eyes perfect for seeing in the darkness, while a set wings appeared to be for appearance only. They each had a pair of horns curling around their face. However a different Zerglings was next to Kerrigan, its right horn was broken about half way.
"What mutations do you have?" Kerrigan asked.
"Adrenal Overload, can increase size of Zergling adrenal gland. Increase attack speed. Hardened Carapace, improve armor on Zergling, increase life expectancy. Metabolic Boost, increase Zergling movement speed." Abathur explained, and Kerrigan chose Hardened Carapace.
"Come we have to reclaim Char." Kerrigan ordered. They left the Evolution Pit and Abathur continued with his work hoping that the Mane Six would prove useful to the Swarm, it had consumed much of his time to infest and change them.
"We have word that a Brood Mother named Zagara wishes to create her own Swarm. She will not join you willfully. She is currently in Char's Acid Marsh, where you stored millions of eggs for future use.." Izhsa told the seven.
"Then we go and collect as many eggs as possible before killing her. Let's go." Kerrigan said, as she walked out of the Leviathan, with the Mane Six following.
The Hive Cluster was created by sacs, they dropped from the sky and left the structures, with a few Drones to collect the Minerals and Vespene Gas. Seven more sacs dropped from the sky with their tendrils flailing in the air until it made contact with the ground, rupturing it, causing Creep and blood to fly in several different directions. It cleared to show Kerrigan and the Mane Six.
"Izhsa what do I have to do?" Kerrigan asked.
"It is simple my Queen, collect at least one hundred eggs, and place them in the Birthing Pond that I have located our Hive Cluster next to." Izsha said, while Kerrigan and the ponies approached it.
"Good let's start collecting..." Kerrigan began, but noticed an approaching Zagara.
"You are NOT the Queen of Blades, you are a weak and pathetic Terran creature!" Zagara shouted as she approached the Hive Cluster with four Zerglings. Then they heard the sound of something bursting from the ground, they could only watch as the bulbous and wobbly creatures broke through the surface, tucked into a ball, and rolled at Zagara, exploding on contact showering her and her Zerglings in a splash of acid.
"What was that!?" Rarity asked, but more of the creatures approached.
"Baneling. Filled with acid, explodes to attack. Explodes by self, or when killed." They heard Abathur say through their mind link.
"You kill me with minions?!" Zagara asked, although she wasn't dead. Kerrigan smirked as she led the ponies forward, and saw a large green egg, which Kerrigan quickly collected.
"Fluttershy, can you hold onto these?" Kerrigan asked, holding the egg out to her.
"I don't know how I would..." Fluttershy replied, but Kerrigan sighed and watched as a Drone approached and took the egg before depositing it into the Birthing Pond.
"Good. Now then let's find out what you six can do..." Kerrigan said as she noticed a large group of Zerglings rushing towards them.
Twilight let out a gasp as they neared and Kerrigan ran behind them. Twilight closed her eyes an heard a loud splat. She opened them to see one of the Zerglings had been slammed into a large stone by Applejack, she was now covered in its blood.
"It's obvious that we're gonna have tah fight! Get ready!" Applejack shouted before she jumped into the air and squashed the group of Zerglings beneath her.
Twilight fired several large spine from her back, which shocked her. This must have been her natural weaponry. She watched as the Zerglings continued to come at them. She began to charge up energy in her horn and fired it which caused a large explosion. Pinkie began to cough and began to shoot small parasites out of her mouth, they were razor sharp and ripped the Zerglings to shreds. She then started to gag and vomited up a large pool of acid which injured any hostile Zerg that touched it. Rainbow Dash began to fire several spike from her hooves, where they came from she was unsure. She then released a pair of miniature eggs that hatched to reveal small flying creatures. They fired objects from their tails at the approaching Zerglings. Fluttershy let out a gasp and covered her eyes, but she felt something strange happen. She uncovered her eyes to see four small round pearl like objects on the ground. They exploded to show four smaller creatures with tiny claws and teeth. They rushed forward and began to spit small globs of acid at the Zerglings, killing the attackers.
"So that's what you do... Abathur did come through..." Kerrigan commented which, got their attention.
"Abathur did this to us?" Twilight asked, and Kerrigan nodded. Kerrigan moved forward and began to collect more eggs with another Drone coming to collect them. It left and placed them in the Birthing Pond. They continued on and found themselves once again face to face with Zagara.
"Enough! While you've been stealing eggs I've been making soldiers. Attack!" She shouted.
"Warning a huge wave of Zerglings is approaching our Hive Cluster! We should defend with all available forces." Izsha warned, and the Zerglings approached. They were quickly killed by the multitude of Spine Crawlers that were built to defend the base. This shocked Zagara.
"You don't even return to defend your own Hive Cluster!? How strong are you!?" She asked, now fearful of this Terran, however she was able to compose herself and quickly regained her confident attitude. Kerrigan and the Mane Six continued collecting eggs until they finally had enough.
"There. Abathur, infuse the Birthing Pond." Kerrigan ordered.
"Simple. Catalytic supplement, accelerated quickening. There." Abathur said as the pond began to glow, and the eggs burst open in a large spray, showing hundreds of Zerglings and Banelings.
"Now to destroy Zagara's Hive Cluster." Kerrigan said as she ordered her soldiers to attack. They began to move through the marsh, but even this massive amount of Zerg wasn't enough to push Zagara to fear, she continued to send her own Zerg to attack. Zerglings rushed at them, Hydralisks and Roaches attacked from a distance, but they were being slaughtered by Kerrigan's Zerglings, Banelings, and the Queen herself. After fighting their way through the marsh, the Mane Six noticed upon attacking a building for a small while it began to bleed, shooting blood out like a geyser it eventually exploded revealing organs and bones. Zagara was out of soldiers... Out of a Hive Cluster... And out of luck...
"Kill her." Kerrigan ordered, and the Zerglings rushed forward and began to tear at her flesh with their teeth and claws.
"I only did as you ordered, my Queen!" Zagara cried out, halfway between pain and sadness.
"Halt... I ordered you to rebel against me?" Kerrigan asked, now suspicious of what she was planning.
"You told all your Brood Mothers to stay strong. You said the Swarm leads by force of will. Your will is strongest so I will serve." Zagara answered, bowing to her Queen. Kerrigan was pleased with this, for she had reclaimed a Brood back into the Swarm.
