An enigma of a villain, Hiltz was once a man of little words. For years the mysterious crimson red haired figure worked in the background, secretly plotting and scheming his way to the top. His goals remained shrouded in mystery to nearly every everyone he knew. Some figured he was just a psychopathic killer, attacking random places, stealing ancient artifacts, and generally causing mayhem for the people of Planet Zi. Not even his closest associate, Rease had all the answers as to what he was truly planning.
Hiltz often enjoyed playing with his enemies. Giving them slight hints to his grand schemes, while still keeping them far enough out of reach until it was far, far too late. A sadistic mad man hell bent on destroying all of humanity, Hiltz often allows defeats to occur, learning valuable data in each loss. Though, he is calm, calculating, and is hardly ever caught off guard. He is often one to also intentionally walk into traps, get caught, only to quickly escape and cause mass destruction around him just to prove a point. That no matter how hard the heroes fight, he is always one step ahead. That their attempts at stopping his grand schemes are futile in every sense of the word.
Despite his calm and often chill demeanor, Hiltz can come off as cocky, as he takes great pride in his heritage as a Zoidian. An ancient race of humanoids that were tragically wiped out by a powerful Zoid. He has been known to even scoff at a regular human, Gunther Prozen's vain attempts at controlling the might Death Saurer, only to fail miserably. As Hiltz is positive, only he could truly possess its raw and destructive power.
Many battles were fought to stop Hiltz, once his scheme had finally been revealed. Though at every battle, his machine, a powerful and unstoppable Zoid proved to be more than a match for anyone. Entire cities would fall, and many soldiers would loose their lives. By the year's end, however Hiltz would meet his fate after a final, last ditch battle which combined forces from all over the Guylos Empire and their bitter rivals, the Helic Republic launched an all out assault. After heavy casualties, Hiltz finally perished.
