The theorized idea is that The Men in Black are DRM operatives (France's intelligence service) that work under the French Government in order to get information of Project Carthage and use it for their own purposes. The Men In Black were sent once they found out that Hopper created Lyoko and X.A.N.A. in order to destroy Carthage, triggering the events of Hopper's disappearance, the formation of X.A.N.A. (as the antagonist) and the virtualization of Aelita Schaeffer. The Men in Black also abducted Anthea Schaeffer, Aelita's mother.
- The Men in Black have many similarities, and are suspected to also be, "The Division" from False Lead. In this episode, they tell Principal Delmas that they are so secret that even themselves don't know who they are.
- However, they’re not the same organisation as the one who is enemies with Franz. The director Sophie Decroisette has confirmed that they’re not the same agents linked to Anthea’s disappearance.
