Otto, also known as "Eyepatch", was a Nazi Gestapo intelligence agent who accompanied his superior Major Arnold Ernst Toht to The Raven bar in Patan, Nepal to retrieve the Headpiece to the Staff of Ra from the bar's owner, Marion Ravenwood. After recruiting some local goons, Otto and Toht entered the bar to interrogate Marion, but were stopped by American archaeologist Indiana Jones and ended up fighting the man in a gunfight.
