The spoiled offspring of wealthy European aristocrats, the Baroness was a student radical who began her destructive activities at universities then moved to the international arena. She eventually found her way into the Cobra organization and became a close associate of Destro and a trusted lieutenant to Cobra Commander. Her relationship with Destro calls into question her true loyalties to the commander, since she allies herself with the strongest individual in an organization and will change allegiances when necessary to keep herself in a position of power.
The Baroness is a member of Cobra in G.I. Joe: Resolute. It's unknown if she retains the high position that she had in the organization in other versions of the franchise, but her relationship with Destro is left intact.
In the miniseries, the Baroness and Destro are part of a subplot in which they have taken a team of scientists hostage. Roadblock, Gung-Ho and Stalker have to rescue them before Destro starts killing them.
- The Baroness was voiced by Grey DeLisle.
