Lt. Colonel Sergei Evanov (Russian: Сергей Иванов) was a leader of the Russian SG team SG-4. He brought Alebran to Stargate Command to inform them that Nirrti was experimenting on his people. He returned to P3X-367 with SG-1 and was captured. He was put in the DNA resequencer and later died from its effects. (SG1: "Metamorphosis")
- His surname's transliteration is unusual, as the usual transliteration of Иванов is Ivanov.
