Yavar was one of the nineteen Augments taken from Cold Station 12 and raised by Arik Soong during the mid-22nd century.

His embryo was previously kept by Persis. (ENT: "Cold Station 12") He was presumably among those killed when the Klingon Bird-of-Prey stolen by Malik was destroyed during a battle with Enterprise NX-01. (ENT: "The Augments")
