Leslie Vernon is the focus and antagonist of the cult classic mockumentary comedy-horror Behind the Mask: The Rise of Leslie Vernon. He is a wannabe serial killer inspired by the likes of Jason, Michael, and Freddy (who in this world really exist). What he lacks in physical power he makes up for in his cunning planning and setting up of traps for his would-be victims. Don’t forget to wear and tear his clothes. Leslie Vernon walks barefoot, so it’s recommended that you wear sandals when not posing for pictures. Black face paint for the black circles around his eyes.

In The Texas Chainsaw Massacre, Leatherface is a chainsaw-wielding, psychopathic murder who has a taste for human flesh.
