This subspecies of Metal King is said to hold within its large body a huge collection of information on the element of earth. Though members of the metal record species mostly go uninfluenced by the knowledge they hold, there is a theory that states that Earth Kings may be comparing themselves against the knowledge they hold inside them which causes them to speak unkindly. Though they express joy when complimented, they're quick to return by saying, "You're still going to fuse me, right?"
Earth King is best used as an ingredient for fusion, providing a base of 11,012 XP. When fused with Earth element units, it grants 16,518 XP, not including Great Success (x1.5) or Super Success (x2). The Earth King only sells for 2,500 Zel.
