Laszlo Mahnovski is a psychotic former child prodigy who was originally contracted by the CIA to work on top secret weapons projects. Items he claims to have designed include Chuck's modified Nerd Herder, the home theatre system at the Buy More, and Chuck's Watch. While he originally stated that he was set up by the CIA for the deaths of his handlers, it can ultimately be assumed that he is in fact their murderer. Seen only in: Chuck vs. the Sandworm.
