Season 1

Nathan started Season 1 as a politician running for Congress. His mother, Angela, believed that the explosion in New York was necessary to unite mankind and that Nathan's destiny was to lead the country through it. Peter started to believe that Nathan was working with Linderman and allowing the catastrophe to happen. Nathan did seem to accept that it was unavoidable. But Claire reminded Nathan that the future wasn't set in stone. Just as Peter began to explode, Nathan swooped down, grabbed him and flew up into space where they exploded without destroying the city.

Season 2

Nathan was alive, he'd lost everything but gained a beard. Taking care of his mother, he teamed up with Matt to find the real killer of Kaito Nakamura. After discovering the killer was really Adam Monroe, he took Matt and headed to the warehouse in Texas. Regaining Peter's trust, they succeeded in overpowering Adam. Trapped in the vault, Nathan had a revelation. Holding a press conference, he began to expose the truth about his power. He opened his mouth, said a few words and was shot dead on the spot.

Season 3

In true Heroes fashion Nathan turned up in Season 3 alive again. Making a miraculous recovery after being shot by Future Peter, he believed God had given him a second (or was it third?) chance at life. He took the job of Senator and negotiated a place for Tracy Strauss on his team. Learning of her ability and finding out she was 'engineered' by Dr Zimmerman, Nathan took her to Hartsdale, where his mother revealed that the same man gave him his powers. Angered, he went to Mohinder but soon experienced Mohinder's emerging dark side. When he learned that his father was still alive and had harmed Peter, he decided to find him and take him down. Arthur told Nathan of his plans to save the world. After Nathan and Peter joined forces to fight The Haitian's brother, Nathan came to a shocking conclusion - that Arthur's idea of taking and giving powers at will wasn't such a bad idea after all. Egged on by Tracy, he agreed to be the public face of Arthur's scheme. He supervised the testing of Mohinder's Intelligent Design formula, and witnessed it giving super strength to a marine test subject. When Peter came to destroy the formula and Pinehearst, Nathan told him that it wasn't too late and that he could see through their father's plan no matter what. Even when a newly super-powered Peter saved Nathan from the burning lab, he was still unrepentant and, as Volume 3 drew to a close, it looked like the warring Petrelli brothers' relationship was broken for good. At the start of Volume 4, Nathan had the power of the President behind him, and set to work in capturing all the heroes, including his brother, Peter. After the plane crash, Nathan arrived to supervise the situation, clashing with The Hunter and trying to prevent him killing the escapees. He then came under pressure from his new boss, Abby, after seeking more funding for the project. She ordered him to shut it down, but after she witnessed Tracy Strauss escape and kill a guard, Nathan was promised all the funding he desired. Nathan then had to fly to the Hunter's house to prevent Peter from killing him. Nathan saved his life but the ungrateful Hunter was growing more frustrated as he disagreed with Nathan's notions of capture rather than extermination. He finally admitted the operation had escalated beyond his control when he was forced to intervene and use his own power to save Peter. Angela surprised him with some information of her own that she whispered into his ear. Nathan's power struggle with The Hunter reached a peak when he began to suspect that Nathan had an ability. Just as Nathan appeared to have won, The Hunter pushed him out of a window, forcing him to fly and give himself away. He rescued Claire and flew her to Mexico, running away from the problems he had caused. Her disappointment made him pull himself together and he decided to return to America. Reunited with his family in Coyote Sands, he uncovered several skeletons and Angela's dark secret. Nathan returned to his office to find Sylar impersonating him. Just as Sylar moved to kill Nathan, Danko knocked him unconscious. Nathan teamed up with Peter to kill Sylar, but Sylar separated the brothers and murdered Nathan instead. After Sylar's capture, he was manipulated by Matt into taking over Nathan's memories, form and life.
