Human-form Replicator

Human Form Replicator's are Replicator's that look like humans. They are composed of millions of tiny cells. Not much is known about their construction, except that neutronium is a key element.

Human form Replicator's are capable of controlling other replicator's, and can only be killed with the Disruptor that Jack O'Neill constructed.

In addition, Human Form Replicator's can stick their hand into the head of humans, allowing them to communicate with them in a few milliseconds and psyhcically visit places in their memories. Fifth also showed it was possible to have both beings enter the human form Replicator's mind.
