Season 1
Peter Petrelli is a hospice nurse who keeps having amazing dreams that he can fly. Later, he stands on top of a building, throws himself off, and is saved by his brother Nathan, who can also fly. Peter eventually learns that his power is actually the ability to absorb the powers of those he meets. Peter visits Mohinder Suresh, looking for the author of Activating Evolution. While Peter and Mohinder are on a subway train, time freezes, and Peter has a visit from a Japanese man, who tells him that Peter must "save the cheerleader, save the world".
When he meets Isaac Mendez, Peter finished a painting depicting a dead and mutilated cheerleader. Peter realizes he must save this girl, and upon seeing another painting, heads to a homecoming, in Odessa, TX. There, he meets Claire Bennet, and manages to stop her from being killed by a mysterious stranger. He falls off a building and breaks several bones, although he regenerates, when Claire finds him, mimicking her power.
Outside the sheriff's department, Peter collapses and has a vision of himself bursting into red flames and exploding in the middle of the city.
