Clara

Clara, better known as the phantom thief Psiren, is woman in the city of Aquroya by day and a thieving beauty by night who is exclusive to the 2003 anime. When she first met Edward and Alphonse, she was giving Ed a shot for food poisoning. Al thought she was a lot like their mother in a way, and felt she was a very kind person at heart.

Later, when her identity was revealed to them when Ed accidentally saw she had a transmutation circle on her chest like Psiren, she told them a story about how the hospital was to be demolished, and she was only stealing to keep the hospital's fate from becoming a reality. Because of this story, Ed helped her escape a trap the police had set for her, in hopes she could save the hospital. The Elrics had high hopes for her... until the next morning when they discovered the hospital had been destroyed anyway. This happened again twice, once as a nun working for a church about to be demolished, and again as a teacher to a school about to be demolished. Ed confronts her after this and defeats her, leading to her arrest. She tells Ed a lead on the Philosopher's Stone she heard before being taken away. On her way to jail, she makes the excuse of being hot so the police will unzip her shirt, allowing her to use her alchemy and escape. Psiren doesn't appear again after this.

Powers and Abilities
Clara is a skilled alchemist, thief, and acrobat. She is also an experienced seductress who uses her sex appeal and well endowed figure to outwit her male opponents when backed into a corner. One of her most often used ploys is to offer (or ask someone) to unzip her shirt, tempting them with the perverted suggestion that she will show them her breasts, only to reveal the transmutation circle on her chest allowing her to use alchemy.
