10 Stargate Characters Who Vanished Without A Trace

10. Hermiod

Hermiod was the Asgard adviser assigned to the Daedalus, primarily to simply oversee the Asgard upgrades that had been added to the ships. Though his appearances were infrequent, he became an essential member of the team, often stepping in to save the day when most other options had failed.

He was strict and a little colder than other Asgard that the SGC had encountered, lacking the relative warmth of Thor and Freyr. However, he did agree to help in battles, such as the Battle of Atlantis, even if he disapproved of his technology being used for war. On several occasions, he used the Asgard beaming technology to send nuclear devices to Wraith Hive Ships, though this was against the Asgard Code.

For this list, it can almost be assumed what happened to him, as he was infected with the same illness that was killing the rest of his race. However, he was in the Pegasus Galaxy when the Asgard decided to destroy themselves and their world, so it is certain he didn't die with them. Having said that, in the show, his last appearance comes in McKay and Mrs. Miller, though he is mentioned by name in Tao Of Rodney. It is never explicitly stated what became of him.
