Lynn Peltzer is the wife to the unsuccessful inventor Randall Peltzer, and mother of Billy Peltzer. She is a housewife who spends her time at home while Rand attempts to make a living selling his inventions. One night he brought home a small creature named Gizmo as a Christmas present for Billy, who was splashed with water on over the night, resulting in the creation of several violent and destructive gremlins. Lynn is very protective of her kitchen and defends it violently from the gremlins.
