Mayday! Mayday! Slip Stream is hit somewhere over the Pacific! What begins as a hurried rescue mission for the G.I. Joe Team turns into a deadly game with Serpentor making the rules. Turning against his own side, the traitorus COBRA warrior has hatched a plot to oust COBRA Commander, destroy COBRA Island, and humiliate the G.I. Joe Team so that the world will turn to him for leadership. Not even Dr. Mindbender--Serpentor's own creator--can stop COBRA's fiercest fighting force from trying to rule the world. But perhaps the G.I. Joe Team can. Hawk and his team of Outback, Beach Head, Gung-Ho, Sneak Peek, Crazylegs, and Leatherneck have a sore to settle, and they're willing to run the gauntlet of lethal COBRA Raven, Dreadnoks, and mindless B.A.T.s in order to stop Serpentor. But can they halt his detonation of the powerful Defender Missle? Only the final seconds will tell...
"Guard duty?" complains Gung-Ho. "I signed up with G.I.Joe to be a fighter, not a baby-sitter." But Gung-Ho's beef about protecting a scientist in charge of a top secret project is cut short by the blare of a frantic red alert. COBRA agent Zanzibar and his Dreadnok troops have infiltrated the high security think tand and have kidnapped Dr. Ehks. Now COBRA possesses the ultimate military advantage - Dr. Ehks's invention, and invisibility machine. And Gung-Ho will get his wish, along with G.I.Joe Team leader Hawk, the massive Roadblock, sneaky Sneak Peek, resourceful Tunnel Rat, quick-witted Lifeline, crafty Psyche-0ut, and the dynamite team of Law and Order. COBRA has launched a 24-hour bid for world domination and the G.I.Joe Team si the only hope to repel the onslaught. But they're up against Zanzibar, invisible Crimson Guard, fighter jets, gunships, choppers - even invisible ammo! How do you fight an invisible foe? Can the Joes find the answer in time?
"Combat, he can handle - but being pushed into a pit teeming with angry, poisonous scorpions? Not even undercover expert Chuckles can joke about that..." By infamous R. L. Stine, creator of Goosebumps children's stories.
"Code One Emergency! COBRA Vipers Invading Pit! Repeat! COBRA Invasion" - Dial-Tone's transmission cutoff. Hawk can hardly believe his ears. COBRA has taken over G.I. Joe headquarters - but is there a connection between the COBRA assault and the kidnapping of the brilliant Dr. Flick, who has accidentally discovered a disintegration ray? And if COBRA possesses the devastating weapon, can a threat to disintegrate whole cities be far behind? Outnumbered and underequipped, Hawk, Psyche-Out, Tunnel Rat, Chuckles, Jinx, Gung-Ho, Fast Draw, and the others set out to rescue Dr. Flick, and race against the clock through the world's largest cities to foil COBRA Commander's plans to vaporize millions of people. But first there's the matter of retaking the Pit. And the G.I. Joe Team plans to fight fire with fire....
