Two Monsters Down...

"One to go," I muttered, kicking the foul demonic corpse away as I pulled my blade free from its eye. I turned and frowned at the Extra-Dimensional Experimental Physicists huddled across the room, cowering in fear of their summoned beasts.
Somewhere distant the clattering crash of destruction pointed out my final prey and I set off in hot pursuit.
Screams and gunfire told me when I was near. "No bullets, ya dingbats! Only cold silver," I grumbled, but try telling a soldier guns don't work!
In truth, it almost cost my own head to learn the lesson. By fate alone I had snatched some Colonel's ceremonial silver sword in desperation when my own weapon was knocked away when I met the first big guy. I only hoped the blade had one last fight in it.
"Hey, ugly!" I distracted the winged brute from feeding on the now-emaciated body of an unfortunate army corporal. The demon, clearly the largest of the three, none the less moved swiftly, bounding instantly toward me at my voice, sending the dead soldier's gun clattering away.
"You're the human!" the hissing threat washed over me even as I retreated. "When you dead, we rule all!"
"We? Time for a head count." I made a show of wiping my blade clean on my cape before leaping to attack.
The enraged creature's roar drowned out the scraping clash of claws against my armored chest, and the clang and screech of my blade off its chitin hide.
Arms like I-beams flailed away at me and it was all I could do to avoid being hammered to death before leaping and planting a lucky foot on his chest. The brute flailed backwards before falling, screeching as one of its bat-like wings snapped beneath its weight.
With supernatural speed I leapt upon it, snapping the cheap silver blade off in my foe's brain.
I turned to look behind me, aware of the gathering group of stunned soldiers and scientists, and casually adjusted my mask.
"My apologies to the Colonel," I said, casually tossing the sword pommel to an awe-struck soldier before disappearing in a flash.
I cataloged this. “Extra Demon-sional: Bring silver when saving the world.”
