Origin
In the comics, Cobra Island is in the Gulf of Mexico. The island is artificially created as the result of a plan by Crimson Guard scientist Professor Appel. False information in Appel's home led the Joes to target an underwater bunker with a massive drop of non-nuclear bombs. The explosion triggered a faultline releasing volcanic stresses forcing an area of the ocean floor containing a sunken freighter Cobra base to rise above sea level.
Realizing the strategic value of the new territory, G.I. Joe attempts to dislodge Cobra from the island via a pitched assault. The G.I. Joe team had nearly won when they were called off by the United States, as lawyers in Cobra's employ had successfully maneuvered to get the island sovereign nation status and recognition by the U.N..
