 Big Boa is Cobra’s top fighting trainer and drill sergeant. A mass of muscle and anger Big Boa is one of the most brutal combat trainers in the world and he expects no less than perfect killing machines to be produced by his lessons and strict exercise regiments.

 Fun Fact: Big Boa was originally created to be the evil counterpart to G.I. Joe’s unarmed combat instructor Rocky Balboa. Because Hasbro couldn’t iron out a deal with Sylvester Stallone they couldn’t use Rocky who was instead replaced by Sgt. Slaughter.
