Quasar

The astrophysicist Karla Scharzchild spent the better part of 60 years staring into the void. One day, the void blinked. A spatial anomaly, essentially a miniature black hole, destroyed the City 7 Observatory, and somehow Karla's dying consciousness bonded to the anomaly. The resulting amalgam became one of the city's most feared denizens, obsessed with recreating the accident on a much larger scale. What appears to be Quasar's body is really just a puppet created by the anomaly, an indestructible shell to house her Core. She uses Karla's memories and multiple PhDs to navigate her new existence, and the anomaly's powers to take what she wants. She can lessen, strengthen, or reorient the effect of gravity on herself and anything she can see. While she knows of things like emotions from Karla's memories, she doesn't understand them, and the idea that she could develop emotions scares her. She is brutally efficient but not sadistic, destroying everything in her way but nothing else.
