text: The director of "The Center". M.O.M. oversees the investigation of paranormal activities throughout the world. Serious, uncompromising, and an expert at hand-to-hand combat, she is often seen multitasking. While Martin's capabilities make him one of her favorite agents, she is often annoyed by his childish behavior. A running gag in the series is Martin destroying nearly every piece of gadgetry she is working on whenever he appears for a debriefing in her office.
  As an agent, the first creature she captured was Gastromo, a parasitic, iron-eating, slug-like monster who infects and controls those he touches. Contrary to the dry sense of humor she provides to the series, Billy has said she is "a real party animal when she gets going". In one episode, Martin and Diana discover she turns The Center into a nightclub afterhours for agents, and they see her dancing. And despite her rather serious and stoic nature, she is always in a happy and festive mood at Christmas, to which a disbelieving Martin comments that it looks like "M.O.M. is actually having fun".
  In the crossover episode of Totally Spies!, M.O.M. is shown to have a possibly romantic history with the spies' boss Jerry, much to the spies' and Martin's displeasure, as she and Jerry spy-flirt between holograms. The initials M.O.M. are said to actually stand for "Mystery Organization Manager", as explained by Martin in that episode. While her real name is unknown, she used the alias Ms. Olivia Mandell (derived from the initials M.O.M.) in the episode "Web of the Spider Creature".
