Karen Nashton (Earth-78)

"The woman before you symbolizes your success. She is your trophy, and she has seen the good in your decision, despite its dishonest beginnings."

- - Joker II

Karen Nashton was the wife of self-help and writer Eddie Nashton, who was secretly a con man and scammer that faked being tortured by the Joker. Going to the weekly reunions of the Joker Survivor Support Group alongside her husband, Karen was captured by Joker II alongside Eddie, their friend Foggy Nelson, their lawyer Jennifer Walters, and their publicist Janet Chang, and used in a series of tests where Eddie had to save them all; all which he failed. Karen, being the last victim, was meant to be saved by Eddie in the same manner he faked surviving the Joker on his book, by impaling two meat hooks on his pectoral muscles. When he failed, Karen was burned alive in the Brazen Bull.
