Zowie

Zowie is the main antagonist and final boss in Gitaroo-Man. He bears a striking resemblance to Kazuya, but the two characters are not related. He is voiced by Douglas Kirk in the English version and by Akira Ishida in the Japanese port.

Role in Game
Zowie is the official ruler of the Gravillian Empire who strives for perfection above all else. He is identified as "Prince", but the whereabouts of the king and queen are not known. He hopes to completely take over the Planet Gitaroo and eventually rule the universe with the legendary Gitaroo in U-1's possession.

He spends a majority of the game monitoring U-1's movements from afar, riding a blimp with an initial of his name on it. When U-1 and Puma near Planet Gitaroo, Zowie beams a transmission of himself to introduce himself to the hero. He demands the legendary Gitaroo and is disappointed when U-1 declines. Still, he continues to send his henchmen after U-1 and stages the final confrontation for the Gitaroos at Gitaroo Arena. When Kirah fails to live up to his expectations, Zowie is forced to extreme measures and dons his own Armored Gitaroo -a type of giant mecha armor with a sabre arm. In spite of his dire straights, he refuses to think highly of U-1 and insults his rival. He then faces the ultimate form of the legendary Gitaroos and is defeated in space. His fate is open for interpretation, but he does admire the legendary Gitaroo's capabilities.

Ming-Ming
Ming-Ming (眠眠, onmyou: Minmin; pinyin Miánmián) is Zowie's beloved talking pet cat. She is just as rude and scornful as her master, but she is content to nap most of the time. Of course, she is on odds with Puma and doesn't really like the hound. While Zowie acts as though he is too proud to accept anyone, Ming-Ming's presence at his side suggests that he can be lonesome.

She is voiced by Lisle Wilkerson in the English version and by Naomi Shindō in the Japanese port.
