Update: we've added new teasers for Ghost Rider and Odin.

A new era is beginning for Marvel Comics this fall thanks to the Marvel Legacy #1 one-shot, which will bring back at least one long-lost character and chart a new course for the company in the aftermath of Secret Empire. This issue will also establish how the the concept of the Avengers dates back far longer than anyone would have guessed. In fact, writer Jason Aaron and artist Esad Ribic will introduce the very first team of Avengers, one that was formed in the year 1,000,000 BC.
