Mecha Petey

Mecha-Petey is the robotized version of Petey in Dog Man: The Bark Knight Cometh. He’s is voice by Len Forgione in the Sound-O-Rama Audiobooks.

History
Dog Man (in the Bark Knight costume) kicks Petey so hard that it angers him and promptly him to use his robotic-powers to beat the Bark Knight, revealing that he is actually Mecha-Petey. Milly is shocked by this, as everybody thought Mecha-Petey was dead. Mecha-Petey replies with "That's what I wanted you to think!" and continues to beat the Bark Knight. He almost defeats him until Milly comes and kicks Mecha-Petey in the head, making his mask fall off and revealing he is actually Porkbelly.

Trivia

 * When Petey revealed he was Mecha-Petey, Milly was shocked, with Chief replying "Mecha-Petey? I thought he was dead!" This implies Mecha-Petey is actually dead.
