He is a bit of a self-absorbed person, with a bad mouth but a good arm, and shouts out the name of his technique, "Jake Attack," when he attacks. He hates the environment on Earth, and always wears a normal suit (space suit) for space even on Earth. In the manga version, he leaves his unit as an escort to return May Kauwin to Side 3. He later fought aboard the Gelgoog in the Battle of A Baoa Qu, and the war ended. In "Gundam Legacy", he continues his anti-federation activities as a Zeon remnant even after the end of the Delaz Conflict, and his character has changed into a more fanatical one. After the Titans attacked, he became desperate and tried to kill his former comrade May, who opposed his activities, but was stopped by Matt Healy and others and captured by the Titans. After that, he was imprisoned, but after being persuaded by May, he seems to have given information about the Zeon remnants' operations.
