Episode 15, "Showdown! The Sorrowful Blue Danube!"
*****SPOILERS*****
Synopsis: The hologram of Kenzo Kabuto is revealed to be a program placed in Gamia to fool Stroheim. Baron Ashura returns to the mansion with a Mechanical Beast borrowed from Count Brocken, demanding to be given the Danube, Stroheim’s giant robot. Ashura is able to use his/her staff to control it, but is confronted by Stroheim. Ashura counters the scientist’s electric shock, sending him falling off of the Mechanical Beast to his death. As he lay dying, Stroheim reveals Lorelei’s true nature, the core of the Danube, and instructs her to take control of it. She complies, much to his delight, and destroys the Mechanical Beast. She then challenges the reactivated Mazinger Z, but Kouji overcomes her. Shiro cries as the Danube, and Lorelei, destroyed, call his name.
