A Real American Hero comics continuity - Devil's Due
After Cobra has captured Alpine, Bazooka, Mutt and Rock 'n Roll at Old Clyde's, Cobra Commander calls for Big Boa to learn just how far the average G.I. Joe's tolerance for pain goes. He arrives just in time to find Bazooka getting free and blowing part of the place. Big Boa has the upper hand until Bazooka takes his helmet off and uses it to hit him on the face. 
When Glenda, Hardball and Rampart track Big Boa and Asa Negra to a Cobra training center in Brazil, they find both Cobra members and their troops dead, and are soon ambushed by their murderers, the Red Shadows.

Big Boas had ten years' experience of training Cobra Troopers and was supremely confident in his ability to subdue all opponents in physical combat. His boasts did not impress many, including Destro. When Jinx broke into the M.A.R.S. building Big Boa confronted her but was soon subdued.

- Big Boa originally was going to have a rivalry with Rocky Balboa from the Rocky movies; Hasbro was working on a deal to make the Italian Stallion a G.I. Joe member. However, the toy company and actor/director Sylvester Stallone never came to an agreement, so the Rocky figure idea was scrapped. Nevertheless, Big Boa still got his release.
- Working names included "Snake Charmer" and "Big Bad."
