Jusnagun
From The re-PSUPedia
Description
Similar to the Neudaiz Tengohg, this is a monster found in the missions Dark Satellite and SEED Awakened. The difference is that a Jusnagun looks like a giant roach-bat instead of a bird goblin. Like its Neudaiz cousin the Tengohg, Jusnagun are higly resilent to melee attacks and like-wise weak against ranged weapons.
