Sam and Dean Winchester dove behind a car, rust specks falling on them and decorating their shoulders like bad dandruff. Dean clutched his rifle protectively to his chest.
"It's going to find us sooner or later, you do realise that?" Sam whispered to his brother.
"Yes, I'm well aware of that Sam!" Dean replied hotly.
A snorting sound from nearby made them both shut their mouths quickly. As they heard the creature snuffle around they stayed in their spots, barely breathing, uncomfortably curled by the bonnet of the car, their limbs starting to cramp up.
Suddenly, the snuffling and sniffing ceased.
"Do-do you think it's gone?" Sam breathed, uncertain.
Dean pulled a sceptical face. "Sounds like it, but you never know-"
A roar cut Dean off mid-sentence and cars collapsed, sliding down eachother like an avalanche. Another pile exploded to the brothers' right.
"Shit!" Dean cursed, all previous need for quiet forgotten. A huge weight crashed down beside them, a huge, scaly, black weight, armed with spikes curving up to half a metre long, inches from Sam's leg, and both the boys yelled in surprise.
Dean grabbed Sam and they bolted from their hiding spot, and just seconds after they'd left, the car exploded into a billion bits of metal, showering them.
"What're we dealing with, Dean?!" Sam shouted over the din. He glanced over his shoulder, and he could just make out a huge creature against the sky, blowing up cars and roaring in frustration as he looked for his prey.
"Oh, I'll just check on my computer for creatures that can turn invisible and blow cars up while I'm running for my life, shall I?" Dean roared back, sarcastically. As if on cue, a huge fireball exploded behind them, and Dean added, "make that an invisible fireball throwing car blower upper!"
The boys dove behind a small wooden shack, knowing full well that as soon as fire hit it, it'd go up in flames. But it was a fair distance for the creature, and that was what mattered.
Sam sighed and turned around to face his brother, and instead looked over Dean's shoulder, bewildered.
A tall man in a tweed coat and a bow tie was standing there, with upswept brown hair and cheekbones as sharp as glass.
The funny man smiled at them and dashed over to them, looking far too excited and happy, given the current situation. Dean turned and faced him as well, outrage registering on his face.
"Who the hell are-?"
"Hello, I'm the Doctor. Basically-" the man poked his head around the shack and saw the creature lumbering towards the shack, then whipped his head back around. "Basically, run!"
