He did it!
Hiro Nakamura is the most light-hearted character on an otherwise serious show. But that doesn't mean his ability to teleport and manipulate the space-time continuum isn't crucial to the storyline.
An ordinary cubicle worker in Japan, Hiro discovered his skill on a small scale at first, setting back the time on his company clock by a couple seconds.
That company is owned by Hiro's father, Kaito, a seemingly important player in the grand scheme of Heroes. As Hiro and his friend, Ando, move along, expect more secrets to be revealed.
In the meantime, go along with Hiro for his inspiring, fun-loving mission to save the world.
