Marvel publisher Dan Buckley stated that the Heroic Age was intended to be more constrained in its scope than previous initiatives: We're trying to get a little bit more into the families of publishing, not as line-wide, to provide people with very digestible beginning, middle, and end content with top characters and top creators in conjunction with the Marvel Universe...

[2]The initiative began in May 2010's Avengers #1, which reunited Iron Man, Captain America (both Steve Rogers and Bucky Barnes), Thor, and Hawkeye as teammates.

[3] The same month saw the start of a four-issue comics anthology limited series called Age of Heroes, with Kurt Busiek writing the lead story.

[4] Busiek's story involves J. Jonah Jameson, whereas Rick Remender's stars Doctor Voodoo, and Paul Cornell features Captain Britain and MI13 and the Young Masters.

[7] The Thunderbolts series, also written by Parker, featured a new Heroic Age line-up, led by Luke Cage (who is also in the lineup of the New Avengers), Crossbones, Juggernaut, Ghost, Moonstone, Songbird and Man-Thing.
