Once a trusted advisor of Baron Ünderbheit, she was seemingly executed by a tiger-bomb for planning a coup d'etat. She survived, however, and subsequently joined the Ünderlandian resistance movement. Following the Baron's fall from power, she became the new ruler of Ünderland and established a democracy. In an attempt to "soften the image of Ünderland" she promptly exiles Baron Ünderbheit instead of executing him. This is quite ironic as Adolf Hitler was a fascist, tyrannic leader.
Colonel Catclops proposes to Girl Hitler, but it is unknown if they ever got married.
