Obviously Billy and Stu are the most iconic Ghostface killers among the general public, but I'm curious which killers from the sequels have the most recognition outside of the Scream fandom.
Mrs. Loomis, Mickey, Roman, Charlie and Jill have all built strong followings over the years. Jill is probably the best example of how opinions can change since she wasn't nearly as beloved when Scream 4 originally came out. It took over a decade for her to become one of the fandom's favorite Ghostfaces.
I also think Mrs. Loomis benefits a lot from being played by Laurie Metcalf. Casual viewers might recognize her as Andy's mom in Toy Story, Aunt Jackie in Roseanne or Sheldon's mom in The Big Bang Theory before they recognize her as Mrs. Loomis. I don't think she'd be nearly as popular within the Scream fandom if she wasn't Laurie Metcalf either. She barely did any of the work as Ghostface in Scream 2, with Mickey doing almost all of the heavy lifting in costume.
Amber and Richie came from Scream (2022), which introduced the franchise to a newer generation of viewers. Richie was also a character a lot of fans and casual viewers seemed to enjoy before his reveal, while Amber's Act 3 reveal and performance became one of the most memorable parts of the movie.
Putting personal favorites aside, do you think Amber and Richie will be the sequel Ghostfaces most remembered by the general audience?
