Superman et Batman et Robin #45

In "Combat sans merci," Superman and Batman team up to take down a powerful Mafia operation, but the mission takes a dark turn when Batman starts to lose himself—his mind unraveling under the weight of deception. As paranoia sets in, he makes a chilling command that puts Robin and Jimmy Olsen in deadly peril. Written by Bob Haney and brought to life by Ross Andru with inks by Mike Esposito, this 1972 classic features a cover by Neal Adams that captures the tension perfectly.
