The Avengers franchise has slammed off the charts, with brave, clever characters embarking on amazing adventures. But what fuels their fire? Tony Stark's obsession with fast cars and fast women conceals a deep quest for purpose. When he witnesses that his weapons have murdered innocent families, his heart literally shatters - he builds himself the new heart of a hero. Captain America's weakness is weakness itself, as Steve Rogers transforms into an outer self that matches the inner, a change mirrored in the heart of every kid beaten up on the playground. Rage rules the Hulk, though it's also his greatest strength when mastered. The Avengers, Agents of S.H.I.E.L.D. and Guardians of the Galaxy find family that complete them, while Daredevil reconciles his split, even contradictory personality. Each hero battles his dark side, appearing as Loki, Red Skull, Kingpin, and other subconscious shadows. Thus, the hero conquers his doubts and harnesses might beyond his gauntlets or guns...he becomes a superhero. With easter eggs, interviews, and comic history, there's treats for all the Marvel fans.
