- "Guess again daddy."
- ―Glenda to Chucky.
Glenda is a separate soul that is mostly inert within her brother Glen's body. She is only able to take control of the body when Glen is stressed.
Bride of Chucky (1998)
She was born from her dying mother Tiffany in the Hackensack Cemetery. Shortly after, she attacked the detective who witnessed her birth. It is unknown whether she or Glen was the one responsible for killing the detective.
Seed of Chucky (2004)
For some reason, Glenda remained dormant in her brother for six years, while Glen had been found and taken in by Psychs. When her brother escapes from Psychs and goes to Hollywood to find his parents and resurrects them, they question his gender. They find him without genitalia, causing Tiffany to see this as a sign that he is a girl, but Chucky thinks he is a late bloomer. They name the child as Glen/Glenda.
Whenever Glen witnesses his parents killing, his eye begins to twitch. Under a severe amount of stress from seeing Tiffany kill Redman, Glenda is finally able to take over. Once Joan enters Jennifer's house, Glenda uses a lighter and hair spray to set her on fire, causing her to fall off the balcony and kill herself. Chucky approaches Glenda, who is pretending to cry, thinking that she is Tiffany. However he is shocked to find his daughter, who begins to laugh hysterically and refers to herself as a "bonus baby". Tiffany tires of her daughter's crazed rants and slaps her, making Glen come back.
With help from a voodoo pregnancy brought on by Chucky's sperm, Jennifer Tilly gives birth to twins. Glenda briefly shows herself when she is excited that one of the twins is a girl. When Chucky is preparing the chant to allow Glen and Glenda to enter the babies' bodies, the police arrive. As Jennifer screams for help, Tiffany yells at Chucky to complete the chant. The stress of the situation causes Glen's eye to twitch and Glenda to reappear, who then shouts at Chucky to do the ritual.
Glen and Glenda finally are split after switching souls with the babies, and Tiffany raises the twins (as Jennifer Tilly). After five years, Glenda has become a problem child, so much so that their nanny Fulvia decides to quit. She explains to Tiffany that Glenda gave a boy a bloody nose and took photos for show-and-tell, called their cat a "cunt", and had been stealing money from her purse. While she sees Glen as an angel, she is afraid of Glenda and the hate-filled way she looks at her. As Tiffany kindly says goodbye, Fulvia turns around and sees Glenda staring at her eerily. When she turns back, Glenda takes great joy in watching her mother beat the nanny to death with her doll body. Tiffany then looks at her daughter, making her promise not to tell anyone of her little "slip".
Murders Committed by Glenda
- Lt. Preston: Attacked his face. Fate unknown, but presumably killed off.
- Joan: Set on fire, then fell to her death.
- The inspiration for her is from the 1953 film Glen or Glenda.
- Glenda made the dress she wears herself, patterned after Tiffany's own dress.
- During their birthday party, a present is sent to Glen with no address. Inside is Chucky's severed arm, which then attacks Glen. Since Chucky was unable to do send the box himself and Glenda enjoys seeing others get hurt, it is possible that she sent it herself to her brother.
