The Petercopter is a helicopter owned by Peter Griffin. The copter itself is simply a light blue helicopter with Peter's face molded onto the front, similar to the Hindenpeter and the Peterdactyl.
The copter is first seen in "The Cleveland-Loretta Quagmire" after Peter calms his friend Cleveland Brown by placing a plastic bag over his head then exclaiming, "To the Petercopter!". The blades cut the leaves from the tree and the copter falls into Joe Swanson's front yard causing a mess.
In "Dog Gone", Lois reminded Peter that he bought the Petercopter, despite the fact that they couldn't afford it.
