This unknown monster is similar to Lagiacrus the same way Zerureusu is similar to Rathalos.It normally inhabits the tower and utilize the Fire element. It is introduced in Monster Hunter Forward.


Unknown is a close relative to Lagiacrus that has adapted to complete life on land. It is Turquoise in color and it has black spikes,claws,and teeth. It is very large (Larger than the Abyssal Lagiacrus) and has legs slightly more adapted to land. Similar to Nargacuga it has evolved a beak like shape on its mouth. It has barbs on its tail that it can shoot at its enemies.It has an metallic skin that it fuses with the earth's magnetic field's power to fly and glide.


It is known to be far more aggressive than Lagiacrus to degree that it kills anything that invades its territory and it is known to be this aggressive to survive in with the strong inhabitants of the tower.Oddly it likes living in human made habitats since it is only seen living in the tower and it is known to invade towns and castles to claim them as its territory.Another reason why it is so aggressive is that it is forced to face equally powerful opponents in the high skies (the opponents are Garuba Daora and Shanthien.)
