"RRRGHRH", Gator-head growled, slowly coming to from an uncomfortable unconsciousness."Excellent question, my friend." a decidedly unfriendly voice responded from the shadows of the white room.
Gator-head looked around. He was strapped to some sort of operating table. Harsh lights shone down on him, heating his reptilian blood.
"Oh, I'm terribly sorry, I haven't introduced myself." said the voice, as the operating table rotated to an upright position. "I am Doctor Hawthorne, PhD."
Gator-head gave the doctor a once-over. He was wearing a white labcoat. His bald head was punctuated by a jagged scar over his right eye, and a black handlebar mustache. He couldn't have looked more like a cliched evil doctor if he had been trying. Perhaps he was trying.
"In response to your earlier question of where you are, you are in one of the operating rooms of my lab. You are the result of a particularly excellent experiment indeed."
"GRAGRGH" Gator-head said, with displeasure.
"What sort of experiment? Well, look for yourself!"
A mirror swung down from the ceiling, and Gator-head looked at himself. To his horror, his head appeared to be that of an Alligator. Or maybe a Crocodile. It definitely did not look like that before he had been kidnapped and taken here, though Gator-head couldn't remember the details of his life before this rude awakening very clearly. Regardless, the new head explained why he was only talking in guttural growls.
Doctor Hawthorne began to laugh maniacally. He had really nailed this evil doctor role.
"That's right! You're the world's first human-reptile hybrid! Or at least, the first one to survive" he added under his breath
"RAWRHGHRR"
"A cure? Well, I do still have your old head in cryogenic storage, I'm sure it could be reattached. But that's really not important to me. I've learned all I need from this experiment, and with that, I bid you adieu."
With a mechanical whir, the operating table rotated to a full upright position. A segment of the floor, directly under Gator-head, slid open, revealing a shaft with no bottom in sight. The binds released and Gator-head fell into the pit, the sounds of Hawthorne's laughter ringing in his ears.
"RRRGHRH", Gator-head growled again, slowly coming to from an uncomfortable unconsciousness again. He was in a dark alley, lying in a puddle. It was very cold. He was still wearing white loose clothing from the lab, with a barcode printed on his shirt. He didn't remember who he had been, but now he was Gator-head, and he would find Doctor Hawthorne and get his head reattached, or die trying.
