Penny's Father is first seen calling Penny and informs her that Dr. Calico and his henchmen have captured him and are holding him hostage but explains that he gave her dog, Bolt incredible super powers so she can find him. He isn't seen for a while in the film, until during last filming set where Calico showed him that they've captured Penny but just as Bolt's lookalike shows up. However unfortunately, the dog gets spooked and accidentally knocks over a fire post that set the whole stage on fire which forced everyone to leave the studio. He was not seen again afterwards.
Penny's Father voice was heard on the phone that Dr. Calico handed to Penny, when he and his men got their hands on her at the ancient temple; before Bolt came to her rescue. Dr. Calico made him believe that he still had her and that he would not harm her in anyway if he build them a weapon. He later made a appearance when he stuck his head out of the helicopter that Dr. Calico was trying to get on, begging Penny to get Bolt to stop the missiles that his captor had lunched.
It is unknown what happens to Penny's Father after the fire, as he was last shown escaping from the fake chair that he was held "captive". However, given some possibility, he may have been either burned alive or escaped and was send to the hospital.
His real name is unknown.
"Penny, I don't have much time."
