Project Superpowers, Chapter One

Having traveled to the hidden city that has been the home of the Green Lama, Bruce Carter III expects to find his death. In the years following World War III, he used an ancient artifact to imprison his comrades, firmly believing that in order to banish evil from the world, the hope of these heroes must also be locked away. But instead, the Green Lama joins him in his quest to reclaim the urn that he, as the Fighting Yank, used to seal away their friends.
