The Trapeze Trio were an attraction in Fritz Tiboldt's Circus in the 1940's. When the group was hired by the Nazi party to tour the United States and eliminate key military officials, the trio would be loyal to the cause. The Trio would be sent to assist their fellow circus performer Omir the snake-charmer assassinate military Commissioner Newsome. Succeeding in their mission they would retreat back to the circus. However they would ultimately be taken down by Captain America and Bucky.
The Trio's subsequent fate remains unrevealed, however as Fritz Tibolt would return to Germany and resume his circus, it is possible that Zandow resumed working for Tibolt. As such, it is noteworthy to mention that Tibolt would later be murdered by Nazi's who evaded capture in retribution of his failure, it is unknown if the Trio would have met the same fate.
