Dominique.
First Appearance: "Wages of Sin."
Quote: "Find out whatever you can about whoever stole that weapon. We don’t want anymore interference. And as for Kristen...you know what to do."
Details: Dominique was the shadowy Dominion geneticist capable of stabilizing new mutant DNA; according to Lexa, she knew "more about genetic engineering than anybody else." Mutant X first encountered her when she hired casino owner Kristen Greg to auction off her deadly prion weapon. Dominique made a final cameo as a member of the Dominion Council watching as Lexa Pierce was being interrogated within Dominion headquarters in "The Assault."
