The handsome, billionaire businessman and commander of the Earthgertz, Klein Sandman's knowledge of science and technology allows him to build the Gran Divas and the Gran Kaiser to battle the Zeravire. Sandman selects people with a high tolerance on the effects of gravity, a genetically inherited trait he calls the G-Factor, to become the pilots of his machines. When it seems the Zeravire are too much to handle for Earthgertz, Sandman approves of combining the Gran Divas and the Gran Kaiser into Gravion. In Gravion Zwei, he pilots the Gran Sigma.   Sandman was originally Zieg Zeravire, a scientist from the ecologically devastated planet of Llambias and the husband to Lufira Zeravire. In order to stop further contamination and to prevent an all-out war between the neighboring world of Selias, due to Llambians forcing themselves to immigrate there, Sandman creates the Genesis Machine Gran Sigma, the prototype to the Gran Kaiser, in hopes of restoring Llambias' environment. Unfortunately, his brother-in-law Hugi Zeravire creates the Genocidron System, an automatic, robotic network programmed for extermination. He intended to use it on the Selians, as a means to spare enough Llambians if war was to occur, but Sandman did not wish to see lives sacrificed. Following a brief struggle with Hugi, he accidentally destroys the control device to the Genocidron System, making the machines indiscriminately destroying both worlds.   Upon escaping Llambias, Sandman and Raven flees to Earth. In order to conceal his identity, he takes the name and appearance of the actual Klein Sandman, an 18th-century aristocrat, and to provide himself the means to prepare for the Zeravire, Sandman genetically enhances his own G-Factor, giving him immortality, thus keeping his youthful appearance. Some time before Eiji's arrival at Saint-Germain Castle, a spacecraft lands on Earth that followed his escaping vessel, carrying his daughter, Leele Zeravire. Sandman never knew of her existence until then.   Klein Sandman makes an appearance in Juusou Kikou Dancouga Nova, which is also directed by Masami Obari.   (Source: Wikipedia)
