After yet another defeat inflicted by G.I. Joe, the immediate subordinates of Cobra's leader, Cobra Commander, have finally come to the end of their patience with his apparent incompetence and his inability to achieve real victories. The leader of the research and interrogations wing, Dr. Mindbender, receives a dream showing the solution. His plan is to collect the genetic material of great warriors and military leaders to create a composite clone that would be the perfect leader for Cobra. Now they set out to put this scheme into motion, and G.I. Joe has very little time to learn of this plot before Cobra becomes that much more a dire threat to the world.

After the death of Shaggy's Uncle Beaureguard, he, Scooby and Scrappy arrive at the late uncle's Southern plantation to collect the inheritance. But as soon as they arrive, they find it is haunted by the ghost of a Confederate soldier. With this spook on their tails while they solve riddles in search of the inheritance, they seek help from the Boo Brothers, a trio of ghost-exterminators to help catch this nasty ghoul.

G.I. Joe faces a new enemy as an ancient society of snake people known as Cobra-La try to forcefully take back the earth from those who drove them underground eons ago.
