Replicator disruptor

The Disruptor was built by Jack O'Neill using the knowledge of the Ancients. The weapon severs communication between the blocks of Replicators or the cells of Human Form Replicators.

The Asgard had previously experimented with a weapon that would do much the same thing, without success. The Asgard also created a sattelite version which could deploy the beam in space.

The Replicator Samantha Carter created a cipher to block this weapon, but the real Samantha Carter overcame this with Thor's help and with the help of Jacob Carter and Baal destroyed the Replicators with the Ancient weapon ofn Dakara.
