Aliens versus Predators: Equestrian Extinction

A changeling, transformed into a fly, sat on top of a roof. His hunger wearing him down too much. He'd need to find food soon, or else he'd starve. He was waiting patiently, his eyes looking over a tall figure in a familiar tree Library.

Scarface felt a tingle up his spine. He looked around, letting his helmet's visions switch. He saw a fly staring at him. Almost like, it knew what he was. Three dots appeared at the fly as Scarface rose his speargun. His aim was now aligned with the fly. He fired, killing the fly, but, he didn't care about that, he cared about what  the blood looked like.

"Green blood?" Scarface said in disbelief, scanning it to see what creature it belonged to. "Almost like Serpent's blood, except it doesn't burn."

"Hey, Scarface, what are ya doin'?" Spike asked, then, his helmet turned to the substance on his finger. "That's Changeling blood. How'd you get that?"

"I didn't. I shot a fly, only to see this on the ground. It was a big fly too, about the size of your big toe. Something's going on, and I don't like it." Scarface said, looking at Spike. His glowing eyes on his helmet seeming to gaze into Spike's eyes.

Spike didn't flinch, but, he scanned the blood.

"Heya Spike, whatcha lookin' at?" Pinkie asked, appearing out of thin air.

"Wait. How- I thought-" Scarface stuttered, surprised that she had appeared out of nowhere without him knowing.

"Pinkie can bend the Rules of Physics apparently." Spike explained, causing Scarface to raise a eyebrow at Pinkie, who was smiling like nothing happened.

"Anyway, there was a changeling here, and Scarface was scanning it's blood, thinking it was Xenomorph blood." Spike said, but then, a scream cut in the air, and the Familiar beating of wings caught Spike attention.

Scarface, however, was quick. He ran towards the noise, Spike running after him. Pinkie, however, was hopping after him. Scarface roared, clearing everyone out of his way. On the other side, a changeling was attacking three fillies. Scarface tackled the Changeling as it leaped, tackling it down in mid jump, then let his wristblades out.

"Huntersss like you ssshall die!" The changeling hissed, but then Scarface lifted him by his throat, the let his mandibles tap each other, making a weird tapping noise.

"That's what you think." Scarface said, then, eh threw down the changeling. "Youngblood, it's all yours." Scarface said, letting Spike get a look.

Spike then let his grey wristblades out, the large blades dull, but shining. He then started to skin the changeling, screams and wails mixing with the sounds of tearing skin and ripping noises. Spike dropped the changeling, it's green blood on the ground as he dragged it to the nearest tree. He then brang his rope out, tied it to the body, lept up onto the tallest tree branch. He then pulled the body up, and roared again.

He jumped down, earning a pat on the back by Scarface. "Nice job young blood. You have skinned your first hunt. You should be proud."

"I am. Let's go tell Twi something's wrong." Spike said, Scarface nodding in agreement.
