Gillman

A true descendant of the once prosperous legendary continent of Mu. A two-headed underwater commander. In order to restore Mu, he sold his soul to Gandora. He received the order from Gades to salvage the crest of a wolf that sleeps deep under the sea, but he was actually aiming to restore Mu. Since he has two necks, he can respond to attacks from all directions and has no blind spots. He dodged all of Rom's and Jet's attacks. Boasting tremendous vitality, even if his head was cut off, he would act with just his head and attack Rom. He fights by transforming his arms into drills.
