Fiction

Devil's Due G.I. Joe vs. the Transformers comics

In 1978, Colton's Adventure Team were fleeing through the Himalayas after another mission with negative effects on General Mihai. In retaliation, Mihai sent two J-6 fighter aircraft to hunt them down, with orders to rid the world of Joe Colton once and for all. In the end, both the planes and the Adventure Team ventured too far into Cobra-La territory, and were never heard from again.
