Kate Kane (Earth-1: Pre-Crisis)

"We all wear a mask of some kind. A cowl, a husband, wife, denial, anger. We all need our shield to protect us from the world. But for people like us, it's not always about stopping a runaway train or disarming a bomb. Sometimes, the best way to save someone is to be yourself."
