A bizarre breed of humanoid monster that has large glowing eyes and silvery, metallic skin that can stretch like rubber. It can attach itself to machines and bond with them to control their functions. This has led many to believe that it is related to the Metalner.
|Monster Rancher 3||"Its body is covered with a special skin, and its large eyes are always shining. There are rumors that it's from another planet, or that is really a machine."|
