Stupid kid

Artist's depiction of Billy.

Billy is an off-screen character. He is first mentioned by Cosmo during The Haunting in Suffield.


Not much is known about Billy. It is implied during Halloween Special #1 that he lives in Cosmo's neighborhood and dared Cosmo, Evan, Nicole, New Evan, and Allyson to spend the night in the creepiest old house on the block. Throughout the course of the night most of the strange occurances in the house are blamed on Billy.
