Synopsis for "The Extremist Vector (Part III of V) - On the Brink"
The Extremists meanwhile, take control of all of Earth's nuclear missiles and launches them simultaneously. Doctor Diehard maintains them in the high atmosphere pointed back towards Earth. Lord Havok addresses the United Nations and demands the complete and total surrender of the planet, or else they will drop the missiles.
In Paris, the JLE consult with Blue Jay who tells them everything he knows about their Extremists, including their possible weaknesses. The team tracks the villains down to Israel and engages them once again. Metamorpho encases Doctor Diehard in a copper shell, cutting off his access to the electromagnetic spectrum. Without the use of his magnetism, all of the missiles begin to drop out of the sky. Metamorpho is forced to release him, so that he can stop the missiles' descent before they detonate. Diehard catches them all and returns them to their previous atmospheric position.
Losing patience with the JLE, Lord Havok orders Dreamslayer to teleport them to an alternate plane of reality – a reality that Metamorpho compares to New York City, "only cleaner".
