Batman The Animated Series The Phantasm (Mask & Claw)

"Your Angel of Death awaits"

The Phantasm (real name Andrea "Andi" Beaumont) is a vengeful vigilante targeting the Gotham City underworld, making her an enemy of her ex-fiancé, the Batman.

Andrea Beaumont is the daughter of wealthy businessman Carl Beaumont and his deceased wife, Victoria. In her youth, while attending Gotham University, she first met Bruce Wayne, and they fell in love. The two had planned to marry, but Andrea returned the ring Bruce had given her and went away with her father. This was because Andrea's father's was working with the Gotham mafia; setting up various dummy companies with which illegal profits could be laundered and/or invested as well as providing guidance of how to hide the illegal funds.

Carl refused and Arthur subsequently sold the knowledge of his whereabouts to the mob. Consequently, the mafia tracked down Carl Beaumont in Europe and killed him in cold blood. After this, Andrea Beaumont descended into darkness and adopted the costumed vigilante guise of the Phantasm to get revenge against those who caused the death of her father.
