Le Chiffre (DU)
Le Chiffre is a Glatorian from the Dark Universe and a member of Shockwave's MECH organization. He owns many weapons and something called a "Compass", which allows him to track teleporting individuals.
Le Chiffre was sent to the OU in order to track down and kill Dukamu, who had apparently angered Shockwave in some way. He followed him to Vassilan, where he fought him for some time. Finally, Dukamu escaped, and Le Chiffre was captured by Nyatera and some Vassilan drones. They took him for interrogation, but then two of his associates, Ultron and John Sheppard, appeared, freed him, and took him and Nyatera to Cluster One.
