As Hiro Nakamura: He was one of the first to embrace his destiny as a hero.
An office worker living in Tokyo, one day he discovers his power to manipulate time and space. His first feat was teleporting himself to the Times Square, New York City into the future, where he chances upon a comic book the 9th Wonders by Isaac Mendez chronicling what he just did.
He witnesses a cataclysmic explosion leveling the city before teleporting himself back to Tokyo. And that began his heroic journey to save the world. His ability to travel in time has allowed him to cross paths with Peter Petrelli both in the present and as a futuristic warrior; saved D.L. Hawkins and his son Micah from a burning car; and going back in time to save Charlie, a sweet waitress who also seemed to have powers.
