Series Information

The first four episodes were advertised with the tagline "Ordinary people discovering extraordinary abilities". At the end of the fourth episode, an event occurs that kicked off the second arc, where the slogan "Save the cheerleader, save the world" has appeared many times. Several characters presume this phrase to refer to Texas high school cheerleader Claire Bennet, who has the ability to rapidly heal from injury, and the apocalyptic visions of New York artist Isaac Mendez. Beginning at the conclusion of the episode "Fallout," a new tagline appeared, "Are you on the list?" As the characters slowly discover their abilities and the existence of others like them, they begin to realize the need to come together to prevent a catastrophe and save mankind.

According to NBC's official Web site, not only do the characters discover their superpowers, but they also uncover a larger picture concerning their superpowers' origins. The characters become involved in each other's lives as they attempt to evade the series' antagonist, Sylar, who is tracking and killing super-powered humans.
