Wallace was a male Altairan and was one of the first Altairans to transfer his memory into an Android body. He gave his life for the station, and died in an accident. He was friends with Sekura, Marith, Bareeth, Hubbald and Harlan. He and Harlan were the last of their race, until he went to the surface of Altair, which killed him. (SG1: "Tin Man")
