G.I. Joe: Sigma Six

The Jo's storm COBRA Castle! Cobra hits the GIJoe team on two fronts—at the North Pole and in the Amazon! The Joes fight off hordes of new-style BATs and deploy some new hardware of their own. The Amazon supply depot is destroyed and Duke is nearly killed by Destro’s arctic trap! Duke decides that it’s time for a change in tactics. If COBRA is to be defeated, the team has to go “off the grid”.

After hacking into the Sigma 6 computer and infecting it with a virus, COBRA sends the Dreadnocks on a rescue mission to free their leader, Cobra Commander. Meanwhile, Duke visits General Hawk in the hospital, and Hawk's son, Scott Abernathy, draws some unwanted attention after hacking into COBRA's computer in an attempt to perfect an A.I. system he's been working on.

With Cobra Commander back in charge, COBRA launches an all-out assault on the Joe's headquarters. Meanwhile, Scott Abernathy and his robot dog Spud are relentlessly pursued by the sinister android Overlord Vector.
