Agatha was a frail old woman who was the aunt of Bruce Wayne. One time, Agatha payed an unexpected visit to her nephew, which complicated his activities as the vigilante, Batman. When she discovered Bruce and his ward, Dick Grayson, trying to sneak out of home on their Batman and Robin costumes, she assumed they were going to a masquerade party and she allowed them to go. However, she decided to follow them and join the party using a Joker disguise, which proved useful when the Dynamic Duo confronted a gang of criminals. After successfully capturing the thugs thanks to Aunt Agatha's intervention, the trio returned home and shortly afterwards, Agatha left Wayne Manor and headed back home.
