Its an old predatory wyvern believed to be a close relative of Espinas and lives in the caves of the Tide Island.Meraginasu is a powerful wyvern found living in the underground caves of the Tide Island. It was once thought to be extinct until it was recently found living underground. In these caves, it doesn't use sight to find prey but it uses its powerful well-developed ears to listen for prey in the caves. From this it is constantly on the prowl searching for any prey or hunters to attack with the slightest sound.Its club-like tail is used like a jackhammer while its horn is believed to be used like a drill. Meraginasu also controls a never before seen electrical element.
