COMIC BOOK BIO BY COMIC VINE
Doctor Kimiyo Hoshi was a prominent astronomer studying the uses of solar power, when she was called away from her studies to examine a cosmic phenomena during the events of Crisis on Infinite Earths. The Monitor, a powerful galactic being with a link to positive matter, orchestrated the events that lead Dr. Hoshi to acquire the ability to control light. Knowing that in order to defeat the Anti-Monitor, the universe would need a helping hand, The Monitor caused an illuminating beam of energy from a large red star to strike Earth. That beam of star light stroke Dr. Hoshi, rendering her unconscious. When she recovered, she learned that she had the ability to control starlight. She would later go on to dawn a costume similar to the criminal, Arthur Light, taking his identity and becoming the new Dr. Light.
