Unbeknownst to the world at large, Cobra already as established a foothold in the United States, specifically the seemingly inconspicuous town of Springfield. At first glance, it has all the appearances of nice little town with nice midwestern values. Stick around, though, and the people might just convince you to stay and believe... believe in the Cobra philosophy.
A Real American Hero comics continuity
Animated continuity - Sunbow
Springfield was a false town Cobra used to sadistically interrogate Shipwreck, who unbeknownst to them had a mental safeguard forced on the sailor by Dr. Mullaney, who Cobra abducted in order to use a formula for destabilizing water.
- The name "Springfield" was chosen as most states in the United States have a community named Springfield. Cobra's base could thus be in virtually any part of the country. Oddly, Rhode Island (where Hasbro is based) dos not have a community named "Springfield".
- Similar reasoning later led Matt Groening to set his cartoon The Simpsons in a town called "Springfield".
