Season 1

When we first met him, Peter was a hospice nurse, but he soon realised his destiny was to save the world. When Isaac predicted an explosion in New York, Peter was told that the key to averting the catastrophe was to save the cheerleader - Claire. However everyone was in for a shock when it turned out that it was Peter who was about to explode above New York. Just as Claire thought she would have to shoot Peter to stop him, Nathan flew down, grabbed Peter and disappeared. A huge explosion followed, and it seemed unlikely to those watching below that either brother could have survived.

Season 2

Peter was found alive but he wasn't in New York, he was in Cork, Ireland, and with no memory his only friend was Caitlin. He discovered Caitlin's brother, Ricky, had a valuable box containing his identity. So Peter agreed to raid a bank with Ricky's gang to get his memories back. But when Peter discovered Elle was looking for him, a scared Ricky sent Peter to Caitlin's apartment, and it was here that Peter painted a futuristic picture of Montreal. As predicted the two headed off, but it all went wrong and Caitlin was left stranded in the future. A confused Peter then met Adam. This guy gained Peter's trust by saving Nathan's life, and the pair set out to save the world again by supposedly destroying the formula. Adam had other plans for the virus and it took Nathan's help for Peter to come to his senses and destroy Virus Strain 138.

Season 3

It was Future Peter that tried to assassinate Nathan. He had cleverly trapped the real Peter in the body of Jesse Murphy, who was safely locked up in Level 5. When the prisoners were inadvertently released, Angela told Future Peter to get her beloved son back. Taken four years into the future, Peter learnt the terrifying truth that everyone had access to superpowers. He then turned around to witness Future Claire shoot dead his future self. On the run he visited his new brother Sylar and learnt his power of intuitive aptitude. Now armed and dangerous, Peter killed his own brother, President Nathan Petrelli before returning to the present where he attacked Sylar and Angela. Peter then headed to Pinehearst where he discovered his father Arthur was alive. Arthur gave him a fatherly hug, but in doing so stole Peter's powers, leaving Peter helpless. Aided by The Haitian, Angela sent Peter to kill Arthur, and after some goading, Peter pulled the trigger. But it was Sylar that eventually killed Arthur. Still at Pinehearst, Peter was determined to destroy the formula and with Flint's help, Mohinder's lab too. When Nathan was in danger of going up in flames, Peter injected himself with the formula and flew his brother out of harm's way. Peter was in for a shock when Nathan told him he wouldn't have done the same thing. Peter's rift with Nathan grew to the point where Nathan ordered his capture, along with the other heroes. He escaped, and working with Tracy arranged to meet Nathan, with the intention of capturing him. They were betrayed, and Peter flew off out of harm's way. Having rejoined Mohinder and Matt he helped drug and kidnap H.R.G. in Costa Verde. Using information from H.R.G's memories, Peter broke into The Hunter's house and held him at gunpoint. Nathan talked him down and Peter left in time to rescue Matt from capture. He took Matt's power to help break into Building 26, and stole information damning to Nathan's plan. He tried to exchange this for Matt and Daphne's release, but The Hunter attempted to kill him instead. Rescued by Nathan, he once again copied his brother's power and flew to safety. Using this power he was able to rescue Angela from capture. Angela's dream gave them a new goal - to find Nathan and Claire and bring their family back together. Peter arrived in Coyote Sands and on Angela's orders, started digging. Having discovered the terrible events of 1961, Peter tried his hardest to forgive Nathan and worked with him to become an unbeatable team. The Petrelli brothers then confronted Sylar, and Peter managed to copy his powers. Using the shapeshifting ability, he posed as the President and captured Sylar.
