Stargate Atlantis Cast: Where Are They Now?

15. Christopher Heyerdahl

Christopher Heyerdahl has been a character actor for years, appearing in dozens of various projects. He has most recently appeared in Star Trek: Discovery as Wen, a raider from Titan eeking out a desperate existence in space.

Long before this, he was Todd the friendly Wraith (friendly being a stretch), the often times ally of the Atlantis expedition. Though he couldn't be entirely trusted due to his nature, he was at least a grudging helper when needed, joining the assault against the Asurans.

He would also return to help when Teyla was recruited to pose as a Wraith Queen, as he needed to lead his own faction that could defeat other Wraith Hive ships.

Heyerdahl appeared in several other roles in Stargate. He also appeared in the Twilight series as one of the Volturi. He appeared in Smallville, Supernatural, Sanctuary and True Blood.
