What is Chucky's full name from the "Child's Play" slasher film?

Chucky’s full name from the Child’s Play slasher film is Charles Lee Ray. He is a serial killer whose soul is transferred into a Good Guy doll in the original 1988 movie.

Before becoming the doll known as Chucky, Charles Lee Ray was known as the Lakeshore Strangler. Detective Mike Norris shoots him during a chase through Chicago, and Ray uses a voodoo ritual while dying in a toy store to move his soul into the doll. The doll is later given to Andy Barclay, whose mother initially believes it is an ordinary toy.

“Chucky” is Ray’s nickname rather than his formal name. The 2019 Child’s Play reboot changes the character’s origin substantially: that version is an artificial-intelligence-powered Buddi doll voiced by Mark Hamill. The original franchise continuity, however, identifies the killer as Charles Lee Ray, played and voiced by Brad Dourif.
