Velma, Scoob and the Misery Machine
Likewise on the back-story. I'm assuming one day the gang ran into an unholy lord of darkness who
Wasn't just Old man Withers. He killed all of them, except the the spunky, cute chick (A la Ripley, Julie James, Sidney Prescott et al.) and she then went on a Resident Evil, Milla Jovovitch, Supernatural, Winchester brothers inspired murderin' spree. I'm wondering if it was just Vampires or Zombies too. I'm voting for Zombies too.
Oh wow! Replace Scoob with Pintsize, the Misery Machine with a Dodge Ram... R.I.P M + D + H.
FAYE THE DOOMBRINGER!!
Also, needs more cowbell.
