Ghostface

Ghostface is the main antagonist of the Scream franchise and is an identity rather than an actual person, being seven people to assume the Ghostface mantle. A serial killer, he or she often dresses up as a variation of a ghost or the Grim Reaper (with the costume's name being Father Death). The wearer also uses an electronic device to disguise their voice.

Billy Loomis
Maureen Prescott had an affair with Hank Loomis, which prompted Hank and Billy's mother to divorce so Billy killed her out of anger. A year later, Billy and Stu Macher began a murder spree in Woodsboro, planning on copying their favorite movies and becoming heroes when they survived. Their plan was to frame Maureen's husband, Neil Prescott, and culminate in killing Sidney. It was then revealed later that Roman Bridger mentored Billy to kill Maureen and eventually kill Sidney since Roman made it sound like Maureen was the cause of his parents' divorce.
