Baltke was a Chiss commander, specifically a male, from the Legends continuity. He held a commanding position in the Chiss Expansionary Defense Fleet and also functioned as both a battle surgeon and an interrogator.
Baltke's activities during the Swarm War included the interrogation of Leia Organa Solo, a Jedi Knight (Legends). He sought information from her regarding her mission alongside her husband, Han Solo (Legends), and the strategic intentions of the New Jedi Order concerning the conflict. Baltke attempted to employ a hypoinjector to compel Organa Solo to reveal the truth, but she skillfully utilized the Force, causing Baltke to inadvertently inject himself.
