- —Todd, explaining Khan to John Sheppard
"Khan" is a Wraith who has only recently come to the attention of the Atlantis Expedition, having previously been a high-ranking but unknown member of Todd's alliance. After sifting through the treasure trove of information his former master had stolen from the DSC-304 Daedalus, he chose the name "Khan" for himself, wishing to inspire the same fear in the Atlanteans that the ancient Mongol warlord had in his enemies. Following a long and incredibly-successful campaign into the Milky Way, however, his superhive and its escorting armada were destroyed in orbit above Earth, thanks in large part to Todd's inside intelligence on his battle plans and the unexpected arrival of Atlantis.
His current status and whereabouts are unknown.
