"Doctor, what are those?" a voice says shakily.
A tall man with almost buzzed black hair grins. His leather coat goes well with his arrogant stance. "I haven't seen one of these in ages! It looks like a psychophysical demonican Vampiry! What are you doing around this planet? Lots of sunlight, unstable atmosphere, it has to be bad on your skin!"
The creature snarls and stalks towards them. "But it looks human!" the woman says from behind him.
"You know what I am, human. I can't let you live," the creature snarls as its forehead becomes wrinkled and its eyes turn into yellow slits. He lunges at the couple. The man punches the creature on the nose and flips him onto his back.
He laughs for awhile before regaining his breath. "I can't believe you little beasties still roam this place! I thought you were all gone. You know, back on the dark moons of Dhampir, no sunlight, extremely low oxygen. Didn't they make a Shadow Proclamation to restrict you to your planet? How'd you make it off?"
"They can't stop all of us," another voice says. He turns around to see twelve of them slowly creeping towards him.
"Ah, but I can," the man replies with a grin. "You see, I'm the Doctor! Rose, toss me that trash can lid, will ya?" She tosses it to him and he catches it with ease. "That's a good girl. Now watch carefully." He immediately slams it onto the creature's neck that he knocked over, decapitating it. The creature screams and disappears in a burst of fiery dust.
The woman gasps, "You killed it!"
"Nah, it's still around here. It is an astral projection now. The Vampiry are Supposed to be stuck on their home moons away from everyone, but it looks like quite a few got out," the man replies casually. "The Earth's atmosphere and sun is too much for them. They can't handle the sunlight and the atmosphere has too much oxygen! So, it looks like they take on deceased corpses as hosts so they can manifest themselves. Since the corpses are dead, they need new blood. I guess that's where the legends of Vampires came from, isn't it?"
The Vampiry slowly creeps closer. "Doctor, what are you going to do?" the girl asks.
"Nothing!" he exclaims cheerfully. "I'm going to walk back into my Tardis and leave. The Shadow Proclamation can look after their own messes. Come on, Rose."
The blonde states indignantly, "What about the humans that live here? We can't just abandon them to these creatures!"
"Humans are a healthy lot. They'll look after themselves," he replies offhandedly as he turns to walk back to the Tardis.
The Vampiry gang runs at him, intent on making him their next meal. He turns around to make some sort of witty comment when a short blonde woman jumps out of the shadows and drives a stake through one of their hearts. It explodes into fiery ash while she kicks two of the Vampiry across the street. Rose watches in shock as the young woman manhandles the Vampiry without a second thought. When they are all dusted, the woman faces them, "You shouldn't be walking around Sunnydale at night, Miss. It's not safe," the girl states bluntly.
"Yeah, I got that part!" Rose says loudly. "What are you? Some sort of alien?"
The girl frowns, "Alien? There's no such thing! Just vampires and demons and whatnot. Well, I have to go. There should be two more rising tonight."
The Doctor pauses and stares at her intently. "You aren't completely human," he states.
The girl frowns deeper, "Yes I am! I'm just a Slayer! My name's Buffy."
"Buffy…oh! A Slayer! So that's what happened!" the Doctor exclaims with a grin.
Rose glances between the two," What's going on?"
"When the Vampiry landed, the humans decided to fight back. They bound a dormant spirit of a Master Vampiry to a girl with genesequence bonding! It's brilliant!" He laughs. "Let's go, Rose. She'll take care of this place."
Rose sighs and slowly walks after him. "What is your name?" Buffy calls after him.
The man turns around and smirks, "Me? I'm the Doctor!" He and his blonde companion walk into a strange blue police box and a strange humming sound fills the air. Buffy watches in awe as the light on the top of the box starts blinking and it fades from sight.
"What in the world?" Buffy murmurs to herself. "Willow and Xander are never going to believe this!"
