Naydern is a woman that Roger meets when he turns Roger's Place into a country and western roadhouse in "Gorillas in the Mist". After Roger tries to prove to Hayley how easy country music is and is booed off the stage, he proposes to Naydern to learn about suffering in order to write a great country song. After their wedding he arrives at Naydern's trailer only to find she doesn't have an espresso machine and leaves. Naydern tracks him down and drags him back where she and her children threaten to shoot him as he tries to escape. Roger fakes being a victim of spousal abuse in order to have Naydern arrested and the children placed in foster homes.
She is one of the savage survivors in "The Two Hundred".
Naydern is voiced by Christina Hendricks.
