It is treated as a "Magna Warrior" monster. (TL note: In JP both "Magnet Warrior" and "Magna Warrior" use the same kanji but the furigana (forced reading) is different. These 2 FAQs serve to make the distinction between the two and establish that furigana can be relevant for archetypal distinctions.)
