Magpie

Magpie appears in the 2013 CG animated show Beware the Batman, voiced by Grey Delisle. Her design for show based on popular singer Lady Gaga. Margaret Sorrow, a kleptomaniac thief, volunteered for psychiatric procedures at Blackgate Penitentiaryto reform and reduce her sentence. The procedure worked, but repressed her criminal urges to the point where they re-appeared as a split personality, Magpie, while as Cassidy, a new identity, she was a meek, shy secretary. In addition, she lost the ability to feel pain and gained the ability to grow long claws as nails. As Magpie, she began to steal "shiny" objects as well as went on a quest to regain her old memories, as well getting her revenge on the head psychiatrists of the procedure. She was stopped by Batman, when she declared that Cassidy was "gone", and only Magpie remained.

Origin
Pye worked as a museum curator at the Gotham City Museum of Antiquities until her obsessive need to possess all of the priceless artifacts made her mind snap and she became her childhood nickname, Magpie, in truth. She made deadly versions of the things she stole, taking the originals for herself, and replacing them with the copies.

Power and Abilities
Magpie has no super powers, though she has the skill to create deadly booby-trapped copies of the pieces she steals.
