Alatreon

Alatreon, sometimes referenced as the "Glittering Black Dragon" is a fierce elder dragon living in a volcano region called the Sacred Land. It is the final end-game boss in online Monster Hunter 3. It is elementally unstable, possessing control over the dragon, fire, thunder, water, and ice elements. When weakened, Alatreon will fly high into the air and rain down ice crystals. These ice crystals fall on random spots while some may target certain players. It is said that it has the abilities of all the True Elder Dragons(Kushala Daora, Chameleos, Lunastra, Teostra), although, since it is elementally unstable, it is unable to truely harness that power.
