|Portrayed by||Bryce Hurless|
|First appearance||Once Upon a Time in Texas|
Hiro accidentally time travels to October 2006 with his hospital clothes on, where he finds himself in front of the Burnt Toast Diner. He then notices a garden, next to the diner, full of clothes. While he is changing his clothes, Petey points toy guns at Hiro and says "hands up", telling him that he can't get away with stealing his dad's clothes. Hiro apologizes and says that it's a matter of life and death and that destiny has sent him there to save the life of the woman he loves. Petey claims that there is no such thing as love. Hiro then tells him the story of his relationship with Charlie. He tells him about how they met and how he traveled back in time to save her and he failed, and whatever he did, in the end the brain man killed her. Hiro then tells Petey not to worry because this time he will stop the brain man and that he's the good guy. Petey gives Hiro a white cowboy hat, saying that the good guys wear white hats, while the bad ones wear a black one. Then, Sylar comes to the entrance of the diner where they are standing. Hiro immediately moves Petey behind his back and stands still. Sylar enters the diner and Petey comments that he was wearing a black hat.
- Petey was credited as "Pistol Petey". (Once Upon a Time in Texas)
