the unconscious Superman to safety. Seeing Supergirl's sacrifice makes Doctor Light realize how selfish she has been, and she resolves to change. When Harbinger summons her to fight in the final battle, Doctor Light is ready. As the other heroes barrage the Anti-Monitor, she absorbs the energy of a gigantic star that he is using as a power source. Scoring the first fall of the Anti-Monitor during that battle, she blasts a gaping hole through him. In the post-Crisis continuity, Supergirl was written out of existence, so it is explained that Doctor Light was inspired by the other heroes. She is potentially one of the most powerful superheroes in the DC Universe, but she has not tapped into the heightened levels of power she used during the Crisis (although few remember those events, Doctor Light is one of the few who do, seeing as how she once mentioned in Showcase '96 #9 (October 1996) that she's faced "Anti-Matter Gods"). Doctor Light has joined the Justice League a few times over the years, most notably as a member of Justice League Europe during the latter half of its incarnation. She also joined an incarnation of the Doom Patrol for a period of time. During her time on the Justice League Europe, she believed that her anti-social attitude during the Crisis was due to the food she regularly ate, after Power Girl is diagnosed with a similar condition. However, her behavior in Crisis was, in fact, her genuine behavior. While a member of the Justice League, Doctor Light formed significant friendships with The Flash (Wally West) and Power Girl. There is a protracted period of animosity with the member of the Global Guardians known as Rising Sun. His romantic endeavours win out and the two enter into a relationship Infinite Crisis and after In Green Arrow (vol. 3) #54 (November 2005), following his recovery from the mind-wipe he suffered at the hands of the Justice League, Arthur Light, the villainous male Doctor Light attacked Doctor Hoshi and drained her of her powers. It appeared that her de-powerment was temporary; in Infinite Crisis #5 (February 2006) she used her powers to aid in the evacuation of Tokyo, Japan. In that same issue she was warned by Bart Allen, in the costume of the Silver Age Flash, of the escape of an enraged Superboy-Prime. She was later seen in Infinite Crisis #7 (April 2006)
