Tanis Reynard was one of the dangerous prisoners on the prison ship Sebrus that overmanned it's crew and guardians and killed most of them. The Sebrus crashed on P2X-005 and they were stranded for several years. They fought the rest of the surviving crew including Captain Warrick Finn. When SG-1 arrived, they agreed to help them power the Sebrus. When SG-1 discovered that they were escaped prisoners, they captured them and handed them over of Warrick. She was eventually, along with Aden Corso and Lyle Pender, transported to prison with the restored ship. (SG1: "Forsaken")
