Season Three

Season three will begin with the third volume, "Villains", during the 2008-2009 United States television season.^{[32] [33]} "Villains" was originally supposed to be part of the second season, however the writer's strike caused the volume to be carried over to season three. The lead-in to the third volume, "Villains", features Sylar. Throughout Volume Two, his powers are suppressed by the Shanti virus.^[34] After using a cure developed by Mohinder Suresh, he regains his abilities, delivering the first line of the volume: "I'm back." Tim Kring has claimed that the new volume will bring a cadre of villains to the show, hence the name.^[35] On December 5, 2007 at the Jules Verne Film Festival Adventure, Tim Kring showed a video-preview of Volume three.<sup>[36]

Season Two

Season two began in the United States and Canada on September 24, 2007 and featured only 11 out of the planned 24 episodes, due to the WGA writers' strike. Season two aired on Mondays at 9:00pm.^[30] Season two consisted of the second volume, known as "Generations." Season two completed its finale on December 3, 2007.^[31]

The second season begins four months after the events of Kirby Plaza. Peter Petrelli, Matt Parkman, Nathan Petrelli, and Sylar have all survived the events of the season one finale, and are trying to return to ordinary lives despite their extraordinary abilities, with the exception of Sylar, who is on a quest to regain the use of his abilities. The main plot arc of "Generations" deals with the Company and its research on the Shanti virus. This research is explored through the Company's founders, whose identities are revealed, as well as through the effects of various strains of the virus on The Haitian, Niki Sanders, Sylar, and others. An amnesiac Peter Petrelli observes the potential devastation of the virus in a future New York City. The "heroes" ultimately come together in an attempt to stop the release of a deadly strain of the virus and avert a global pandemic.

Interwoven with the main plot are several secondary plots. These include Nathan Petrelli's recovery following the events at Kirby Plaza; the journey of new characters Maya and Alejandro from Honduras to the United States, and their interaction with a powerless Sylar; Claire and Noah Bennet and their family adapting to a new life in southern California; Claire's relationship with her boyfriend West; Monica Dawson discovering her powers in New Orleans, with the help of her cousin Micah; Matt Parkman's reunion with his estranged father, leading to discovery of new abilities; the Company's manipulation of Mohinder Suresh; Ando Masahashi trying to piece together what happened to Hiro Nakamura; and Hiro's journey to Feudal Japan, where he meets his childhood hero, Takezo Kensei.
