text: Together with Athena, Amadeus and Hercules next confront the new head of the Olympians, Hera, and travel to the Underworld to rescue Zeus from Hades. There it is revealed that Cho's sister is still alive and missing. Upon learning this, he tearfully leaves Hercules, determined to find out what happened to his sister.
  Venturing to the town of Excello, Utah, he encounters former FBI Agent Sexton, who had contacted him shortly after the death of his parents, and battles Dupree. Cho realizes the potential of his brain to serve as a 'hypercomputer', and figures out that Sexton is in fact Athena in disguise.
  Amadeus finally confronts Dupree in person, and learns that Dupree was not aware of Amadeus' sister being missing. Amadeus also learns that his destiny is to be the new hero of the modern era of reason and to stop the "primordial darkness." Dupree then challenges Amadeus to a specialized version of Russian roulette, which Amadeus refuses to do, leaving Dupree to simply shoot himself. After grieving about the situation, he then discovers the truth about Hera's mysterious "Continuum" project.
  Parallel to those stories, in the aftermath of the "Secret Invasion" storyline, the character is used by writer Dan Slott in his run on the Mighty Avengers series.
