The Flyman is an altered version of a fly. The flymen don't attack very often and their attacks are extremely easy to dodge. During the beginning of the battle it will hang back if not interested in what's going on and then suddenly it will fly towards Aya. The flyman will then begin to spew large green acidic puddles near Aya. While the acid puddle are easy to dodge it can be harder to if the other NMCs that accompany the flyman have not been taken out yet.
