During a random travel back in time, Batman and Superman saved a woman accused of being a witch from being drowned. A series of convoluted events later, and Batman ended up being accused of witchcraft, leading to Superman not hesitating to try and burn him at the stake. It was later revealed that the Man of Steel was possessed by an ancient entity, and this point is in some ways more embarrassing for him, especially as the Caped Crusader ending up taking him down by throwing a tiny Kryptonite pebble at his fellow hero's head.
