Action Force #4/1988

In a tense standoff on Cobra Island, the fate of Storm Shadow hangs in the balance as Dr. Mindbender preserves his remains for sinister experimentation. With Cobra issuing a stark warning to the U.S. over the island’s strategic value, Zartan attempts a desperate escape after a blood test exposes his true identity—only to be thwarted by the arrival of new recruit Sgt. Slaughter. As the Jugglers cut off access to the island, Hawk faces a growing threat from an enemy that’s no longer just fighting for power, but for leverage.

In "Serpentor," Dr. Mindbender unleashes a terrifying new threat by combining the genetic legacy of history’s greatest warriors with Storm Shadow’s skills to forge the ultimate Cobra leader. When Ripcord, posing as Zartan, delivers the location of Cobra’s hidden base beneath Springfield before being captured, General Hawk marshals the Joes for a desperate assault on the underground fortress.
