Peter Petrelli, portrayed by Milo Ventimiglia, is a fictional superhero on the NBC superhero drama series Heroes. He is a hospice nurse-turned-paramedic in his mid-20s with the power to absorb and mimic the powers of other people with special abilities, or powers. Sensitive and compassionate, Peter was initially defined by his complex relationship with his older brother, Nathan. Since that time, Peter has had to deal with the outcomes of the decisions that his abilities force him to make. Towards the end of the first season, Peter absorbs the ability of a man who is practically a ticking time bomb. In desperation all the characters in the series race to try and save New York City in fear that Peter will "blow up" the city like a bomb. Minutes from when he's about to explode, Peter's older brother, Nathan, flies him high above the skyline and saves the people of New York City.
