Arella

In the Teen Titans comics and animated universe, Angela Roth, commonly called Arella, is the pacifist mother of the superhero psychic Raven. She is the wife of Trigon the demon, who seduced her in human form in order to produce someone who would later serve as his portal to Earth.Although she knew Trigon was a demon by origin, she thought Trigon's human form was authentic. When she realized Trigon's true form, it was too late and Trigon raped her. After she was impregnated by Trigon, Arella attempted to kill herself with pills in an abandoned allyway. Instead of dying, however, she was taken to the temple Azarath, located between all dimensions. It was there that she was taught pacifism and had her named changed to Arella (which meant Messenger Angel to the Azarathians).
