Twilight entered the lab, instantly the smell of oil, strange chemicals, and the fear of Terrans hit her nostrils. She was disgusted, the Terrans had built all of this to create some Protoss and Zerg monster. Stukov had warned them of the lead scientist here: Dr. Narud. A shape shifting beast that serves the one that corrupted the Zerg. He serves the fallen Xel'Naga. She was the first one, but waited for the others to arrive. She heard their footsteps behind her, and she knew that they were ready to continue their assault. Kerrigan entered to hear a voice with an accent that she couldn't place.
"You are not velcome here Kerrigan." Dr. Narud said, but Kerrigan began to ignore him, as one of the Hybrid began to awake, and a special aura wrapped around the creature, then it moved around Kerrigan.
"GAH!" Kerrigan cried out in pain, which made the ponies and Spike rush to her side.
"My Queen! What's wrong!?" Rarity asked, worried about Kerrigan.
"It's attacking me with its psionic powers! Kill it now!" She shouted, which prompted them to take action.
"Let's go! We need to destroy that Hybrid!" Spike yelled, and they began to rush towards the Hybrid's location. The Hybrid floated above the ground and it was obvious that it had a Protoss shield. They jumped at the Hybrid and began to attack it, but it wouldn't go down without a fight. The Hybrid lifted up Pinkie with its Psionic abilities and slammed her onto the ground, it created four more of itself, all of which began to fight. The ponies were shocked at the raw power that these creatures held, and that they could easily destroy us. Twilight inhaled and her horn began to glow. She launched a large orb that exploded on contact with the Hybrid. It stopped attacking and raised both of its hands towards the sky, before it exploded in a flash of blue light.
"One down... Who knows how many more to go..." Applejack muttered.
"Twilight. I sense something... A Zerg mind... Captured and powerful... I don't know what its called, but it could be useful." Fluttershy said, and Twilight nodded before they began to search for the Zerg creature. They eventually found it, and it was chained down to a platform. They rushed forward and began to kill the Dominion soldiers that guarded the beast. Upon their death, Fluttershy was able to take control of the beast.
"Zagara told me about these things... They're called..." Spike said, snapping his fingers trying to remember. "Brutalisk! That's it! This is a Brutalisk! Even bigger and stronger than an Ultralisk! They can even attack flying foes, and not to mention they move pretty quickly despite their size." Spike shouted, just as another Hybrid woke.
"Oh damn! We need to move now!" Twilight yelled, and they quickly moved destroying Hybrid after Hybrid, not leaving anything that crossed their paths alive. Eventually they learned that only two Hybrid remained, and after a brief discussion they located and destroyed them, saving not only themselves, but Kerrigan as well.
"Good. Now we go after Narud." Kerrigan said as they moved deeper into the lab, soon joined by Stukov.
