Nathan Petrelli, ambitious, pragmatic and an aspiring politician
inspired by his father, seeks to one day help the world by occupying
a high position in the government. Nathan made many questionable
choices and did or supported many bad things during his long and
painful struggle for power. In the end, Nathan, upon succeeding in
becoming New York State Congressman, realized how much his efforts
had cost him when his beloved, yet somewhat estranged, younger
brother detonated above the city.

Resigning from office, Nathan went through a long period of depression,
steadily driving his friends and family away, though with time, coupled with
Peter's return, did Nathan resolve to make things right. To this end, he
attempted to reveal the existence of evolved humans to the world, only to
suffer an assassination attempt.

Miraculously recovering, Nathan attributes his healing to an act of God, and
believes evolved humans to be God's servants to His will on Earth. To this
end, Nathan has since accepted the position of Junior Senator of New York,
with Tracy Strauss as his aide. Nathan eventually pledges his allegiance to
his father's plans to synthetically give people abilities, despite his father's
previous attempts to kill Nathan. Unfortunately, these plans fail, so Nathan
reveals the existence of evolved humans to the President, like he tried to
before he was shot. They both agree to have the government capture them
and place them in a facility where no harm can be done.

Tracy Strauss. Born in August 24, 1974, to parents unknown. Tracy is one
of triplets, the other two being Niki and Barbara. However, when
Tracy's parents died in an unspecified accident, the girls were
taken by the company and experimented on. They were each
injected with a formula to give people special abilities and each
given away to a different home. Tracy didn't discover her special
abilities until the age of 32, when she grabbed a reporter by the
arm and being upset, she accidentally froze him to death.

Until then, Tracy had been working as a former political adviser to
New York Governor Robert Malden. Upon Nathan Petrelli's appointment
to Senator, she was hired as the Senator's adviser. But after killing
the famous reporter, Tracy resigned her position as Nathan's adviser,
only explaining that she couldn't do "this" anymore. It was then
revealed to Nathan that Tracy was planning to kill herself, and so he
flew around the district of Washington until he found her on the ledge
of a bridge, ready to jump. Nathan flew in just in time to catch her, and
the two spend the evening together in her apartment. Later Nathan
confronts her about the incident and she confesses the murder. While
she tries to turn herself into the law, however, Nathan takes her to the
company to find some answers, and there they both discover they were
experimented on as babies by Nathan's mother, Angela.

Tracy serves under Nathan faithfully, and even joins forces with his father
because she believes this will help Nathan become president one day.
In fact in one of the futures revealed in the third volume, Tracy is shown
as Nathan's first lady. But Nathan decides to fire Tracy when their visions
clash.
