Charlie is a male Tau'ri.
Alternate realities
- In an alternate reality, he was the Chief of Staff to President Henry Landry in 2007. He forced Lt. Colonel Samantha Carter to go along with the President's strategy by threatening that he would punish her by financially harassing Rodney McKay. (SG1: "The Road Not Taken")
Behind the scenes
- Michael Chase previously played Ancient Med Tech in the Stargate: Atlantis episode "Echoes".
- It seems at least plausible that the character may have been named in reference to The West Wing's Charlie Young, the President's body man.
