Bringing together these Man of Steel crossover stories for the first time, Superman faces the universe's deadliest foe, but is he truly strong enough to emerge victorious? Even if he survives his encounter with the Xenomorph, how many innocent lives must he also protect from this deadly Alien menace? But how would Superman handle a voyage into the world of Madman with a fractured mind? And what if the last son of Krypton's pod had crashed, not in Kansas, but in the jungles of East Africa, usurping Tarzan's place in legend?
