Hey everybody. I had this idea inside my head since I finished StarCraft2: Wings of Liberty.
There are a few Starcraft x RWBY crossovers but I didn't see any crossover like this one.
Nevermind. Now onto the story!
Disclaimer: I do NOT own StarCraft nor RWBY. They belong to Blizzard and Monty Oum respectively.
Pyrrha collapsed. Her ankle, pierced by dust arrow, finally refused to cooperate. Cinder, filled with the power of a Fall Maiden approached her forming another arrow on her bow. With a smirk, she pulled the string. Pyrrha closed her eyes waiting for the pain. But it never came.
"What?" Pyrrha opened her eyes. she was surrounded by a protective bubble of purple energy.
"I cannot allow my daughter's friend to be killed like that." Both of them turned towards the shadows filling the corners of Ozpin's destroyed office. From the shadows came a person garbed in a white, hooded cloak similar to Ruby's.
In the same time, Ruby finally managed to climb the tower. She landed ready to fight Cinder but the sight before her made her freeze. The cloaked person held Cinder high in the air by the throat slowly choking her. The person's arm was colored purple and green and was covered in some kind of exoskeleton-like armor. Fingers, ending with claws were digging into Cinder's throat drawing blood and further weakening the False Maiden.
"Mom?" Ruby whispered recognizing the cloak.
The cloaked individual turned her head, revealing the face of a person that died over a decade ago.
"Hello, my dear gem." Said Summer Rose smiling warmly towards her daughter. "I believe that we have a lot to catch up, but first let mommy deal with trash."
Summer's right eye turned purple and alongside left sprouted a flame of energy corresponding to its color. Her claws started sparkling with purple and silver lightning and Cinder began to trash in Summer's grip. With a sickening crunch of breaking bones Cinder's body fell limp. Summer released the corpse from her grip letting it fall to the floor. The corpse glowed and an orb of energy shoot from it towards the elder Rose. She smiled and caught the orb revealing that her left arm looked similar to right. She squeezed the orb and slowly Turned it into a small amber gem. She pocketed the gem and turned towards Pyrrha. She kneeled in front of her and touched the wound. To the spartan's surprise wound almost instantly closed. She smiled towards her savior and fainted, exhaustion finally kicking in. White-clad Rose gently laid her in the most comfortable position.
Older Rose stood up and turned towards her daughter only to brace herself against a red missile that slammed into her chest and enveloped her in a tight hug. Momentary silence was shattered by Ruby's loud sobs. She held her mother like she were afraid that she will disappear. Both of them fell to their knees. Summer slowly rocked her child patting her head. After a few minutes, sobs were replaced with soft and steady breathing when Ruby fell asleep.
Summer lied her down and looked up. From the clouds descended a bulbous creature. It hovered in front of the tower. Former human and strange creature seemingly communicated and it put Cinder's corpse inside its body. Summer made her way towards the art of the new roof of the tower that gave her the best view at Vale.
In The same moment, dozens of brown, worm-like creatures burst from the ground all over the city. The beasts opened their massive jaws and from them, thousands of different creatures poured out and started ripping to shreds everything that looked like Grimm or attacked them first.
The Zerg Swarm have arrived.
Over 5000 Zerglings and their evolutions spread all over the city hunting in packs consisting of 1-5 Raptorlings assisted by 3-4 Zerglings per Raptorlisk and 6-9 Swarmlings per Zergling. 500 Roaches protected 1500 Banelings that laid waste to enemy fortifications and mechs while about 2000 Hydralisks filled the skies with razor-sharp bone needles coated in acidic poisons. 250 Ravagers positioned themselves nearby Nydus worms and provided long-range artillery support. Then the stolen cruiser started to turn to aim at Zerg forces. But it was too late. 800 Mutalisks swarmed it and started ripping into its hull with their glaive wurms. Next was the Corruptors. 400 floating squid look-alikes spitting their projectiles at the cruiser were it's the last nail in the coffin. If the White Fang's ground forces thought that it was the end of Zerg land reinforcements they were sorely mistaken. 250 Broodlords started firing their broodlings. Suddenly Every Nydus worm spat another beast. At least 8 meters in height those were one of the most powerful Zerg creatures on land. Ultralisks. Each one of those beasts had four blades capable of cutting through steel like a wet tissue paper. Moving on four thick Goliath-like legs these massive creatures cut through enemy forces without mercy slaughtering them by hundreds.
The Dragon did not fare better. It's wing's membrane was mostly melted off or ripped apart so it had to fight on foot against Ultralisks. It managed to kill one of them but when it tried to follow the next one something slammed into it, knocking it back. Dragon barely got up. The new arrival roared and slammed it's symbiotic spine crawlers into dragon's hide. The Omegalisk pulled the dragon closer and tore into its body with its massive kaiser blades. The blades cut through scales and skin like a hot knife through butter. Black blood flew into the air and massive Grimm fell to the ground in four pieces that started to evaporate. Omegalisk roared performing a mighty stomp that caused a small earthquake. Seeing that its mission is complete it burrowed and disappeared.
Summer smirked. She turned towards her daughter and saw her resting on a carpet of creep released by an Overlord that arrived a few minutes ago. Beside sleeping girls stood a Queen watching them. Summer closed her eyes and her smirk widened when she sensed that most of the enemy forces either fled or are dead.
"And so… the new age began. Prepare yourself Salem. You started a war with a wrong person. Your forces will fall. Your plans will be shattered. Your might will be broken. The Swarm is an unstoppable force of nature. It's endless, unbound, unlimited. And I AM The Swarm!"
Right now I will let it stay as a one-shot. Let me know in the reviews if you want it to become a full story.
See ya later!
