My name is unpronounceable in the human tongue. You may address me as The Being from Klystron 7!
For reasons which shall not be disclosed here, I have been banished from Klystron 7 to live my tormented life on the outer rim worlds. I have chosen Earth as my current home, living in the mysterious subterranean underworld of your cities. Occasionally I exit my lair at night, exploring my nocturnal tendencies.
My current roommate is crimefighter/vigilante, The Blind Guy. He doesn't know I'm an alien though (because he's blind), so don't tell him. I've got a sweet deal on rent, and I can park my flying saucer in one of the lower-level caverns.
Anyway, you must fear me Earth humans! I posesss the intellect of a thousand worlds! Human females are inexplicably drawn to my superior pheremonal glands!
Yessssss....
