Hartley Winterbottom, now known as Alexei Volkoff, is the head of Volkoff Industries and a former MI6 scientist. He was the primary antagonist in the first half of the fourth season of Chuck, however his first physical appearance was not until the seventh episode, "Chuck Versus the First Fight". Harley worked for MI6 as a scientist, helping Stephen Bartowski with the Intersect. While working on it, Harley was asked to go on an undercover mission, his identity that of Alexi Volkoff, an arms dealer. Stephen uploaded the Intersect to him, attempting to aid his mission. However, the Intersect was corrupt and it erased his original identity of Hartley Winterbottom, leaving him only with his cover of Alexei Volkoff.
