Your flesh is a relic, a mere vessel. Hand over your flesh and a new world awaits you. We demand it.”
― Machine Ambassador[src]
After the Machine War, the Machines sent another ambassador to the UN, where they signed the Instrument of Surrender - a formal document which allowed 01 to have total control over the last human territories. The new ambassador also claimed that the surviving humans will be handed over to the machines for use as power sources for them.
After giving this address, the ambassador - armed with a small nuclear device - exploded, destroying the UN assembly along with New York City and the last remnants of the old human order.
