- "It's difficult for Kanaan. He has Torren and me, of course, but I still think he feels isolated."
- —Teyla Emmagan
Since childhood, Kanaan had realized he was among the few members of his people who possessed Wraith mental abilities. Teyla shared them, allowing them to quickly bond and become close friends. In terms of personality, Kanaan is described as a natural leader of their people, though he had no idea until he grew older. Kanaan maintained his relationship with Teyla, even after their relocation to New Athos. Eventually, they took the next step in their relationship and became romantically involved.
Kanaan and the rest of the Athosian population were taken by Michael Kenmore. Teyla was unaware of this fact for some time, though was concerned for their well being, especially when she learned one of their nights together left her pregnant with their child. (ATL: "Missing")
Kanaan was one of the first among the Athosian captives taken by Michael and his mercenaries and subjected to a process that transformed them into Human-Wraith Hybrids. Michael, in his plot to take Teyla's baby for his plans for domination over the Pegasus Galaxy, used Kanaan's link to her mind to lure her into a trap. While on board Michael's cruiser, Teyla desperately tried to reach some part of Kanaan's original personality, so he could help her escape, though Kanaan was completely loyal to Michael and merely stated that their baby would suit their cause.

With time, Teyla's efforts succeeded, and Kanaan's human side resurfaced (despite his altered physiology). Despite this, Kanaan could not act to free Teyla without Michael turning on him and killing them both. Kanaan served on the bridge of Michael's cruiser, during their battle with the Daedalus, and left to investigate the disabling of the ship's hyperdrive. As he went to the engine room, he ran into Teyla, carrying their new-born son, Sheppard, McKay and Ronon. Kanaan, enraptured by their new-born child, was convinced to help them escape now that they had the chance, and as such lead them to a Wraith Dart which they used to escape through the Stargate while the Daedalus destroyed Michael's cruiser.

Upon their return to Atlantis, Kanaan was repatriated with the rescued Athosian peoples in their colony on the mainland of Atlantis' new planet M35-117, and also began the process of regaining his humanity by being treated with a modified version of the Iratus bug retrovirus by Dr. Jennifer Keller. He was initially held on the mainland by Atlantis' new Expedition Commander; Richard Woolsey, until he believed he could trust him, but several weeks later, he was released and allowed to live in Atlantis, his humanity completely regained. Kanaan currently lives with Teyla, looking after their son together, and supported her decision to resume her duties on Lt. Colonel John Sheppard's team. (ATL: "The Seed", "Broken Ties")
