Talus was the leader of the Asuran force which took Atlantis, killing the Lanteans there. He personally probed the mind of Major General Jack O'Neill, and learned of Lt. Colonel John Sheppard's team plan to use Niam against them. He was destroyed when Dr. Rodney McKay rigged Atlantis' shield emitters to emit a massive Replicator disruptor wave. (SGA: "The Return, Part 1", "The Return, Part 2")
- It's possible that, like Oberoth, Talus could be replicated again, though he would have died in the destruction of Asuras.
