Cobra-La
Cobra-La is a fictional civilization created by Hasbro for the military-themed toyline and TV series G.I. Joe: A Real American Hero. Introduced to the public in G.I. Joe: The Movie and the 1987 series of action figures, Cobra-La was created as a reference to James Hilton's Lost Horizon, and the name itself is likely a pun on Shangri-La. It was originally meant as a working name, but Hasbro liked the name so much that it remained.
