Arella

Born Angela Roth in Gotham City, she ran away from home and became involved with a cult that enacted a secret ritual to appeal to the interdimensional being Trigon; she was assaulted/impregnated by Trigon (in human guise) and later attempted suicide. Instead of dying she was taken to the interdimensional temple of Azarath, where she changed her name to Arella (described in-universe as meaning 'Messenger Angel'), gave up her maternal care to the priestess Azar and joined the Azarath community. In later narratives she takes over guardianship of her daughter Raven after Azar's death, establishes a sanctuary ranch for troubled women on Earth, and in at least one storyline sacrifices herself (with Danny Chase) to stop Raven, merging with the souls of Azarath into the composite entity Phantasm (all plot elements summarized from DC Comics sources as recorded in secondary summaries).

Sources do not provide a single, detailed canonical physical description. Summaries describe Arella as a human woman (Angela Roth turned Arella) portrayed across comic-book issues and adaptations in varied visual incarnations; the provided sources note biography and roles rather than consistent physical traits or costume details. Canonical portrayals across media depict her as a mortal female caregiver figure, but the sources supplied lack a definitive, detailed visual specification.

The available sources do not attribute innate supernatural powers to Arella herself; she is consistently characterized as a pacifist, spiritual caregiver, and leader/member of Azarath's community. Her notable narrative acts include giving up direct maternal custody to Azar, later assuming guardianship of Raven, establishing a refuge for troubled women, and participating in a sacrificial merging with the souls of Azarath to form Phantasm in a specific storyline. These events are described as plot developments rather than a catalogue of personal supernatural abilities driven by Arella's inherent powers.
