In Marvel 999, the heroes you know stand at the crossroads of revolution and reckoning. The Avengers are disbanded, fractured by internal conflicts and shifting allegiances. The X-Men are stretched thin, fighting a war on multiple fronts against anti-mutant legislation and the underground horrors of Weapon X2. Meanwhile, the Young Avengers rise, a new generation of heroes forced into battles they never asked for, while the shadow of an Armored War looms over them all. As old legends fight for relevance and new legacies are forged, the question remains: Will this new era of heroes rise together—or tear each other apart?
