Dark King Zylpheeza

Dark King Zylpheeza (冥王 ジルフィーザ) is the demon of Aerial Calamity, is Grand Witch Grandiene's second born child and leader of the Psyma Family with the title of Dark King.

Though he hates humans, Zylpheeza is deeply loving to his siblings and mother. He was admired by Beast Baron Cobolda and Evil Spirit Princess Denus. After being man-handled by the GoGo-V, Zylpheeza went on a personal war with them that resulted in his death at the hands of the Max Victory Robot. After a few attempts, Zylpheeza was resurrected, at the cost of Denus's life. He soon learned the truth of his mother, after killing his younger brother Cobolda, under the influence of her.

After hearing the words of Nagare Tatsumi and Shou Tatsumi, Zylpheeza awakens, just to be killed by his youngest brother Destruction God Salamandes Dragon and revived as a puppet. Though he regained himself, Zylpheeza was possessed by Grandiene's spirit and had to be killed upon his transformation into Destruction God Zylpheeza II (Hakaishin Jirufilza II), with the Max Victory Robo Sigma Project.
