Babyface Killer is the alter ego of multiple characters in the respective films and therefore information regarding Babyface must be included in the respective character pages who have donned the mask/identity.
But I guess we could create not an article page, but a disambiguation page for characters who have been Babyface Killers.
Of course, we would appreciate any help we can get! Just remember to not include the sequel's events yet (if you have already watched the film, which had a few early screenings). If you have any questions, you can contact me, even if I'm currently busy on other wikis. I'm mostly online so I will see any messages that pop up. Happy editing!
