The rapid transformation of his enemy caught Hunter completely by surprise. Rather than the satisfying feel of metal hitting flesh, his fist flowed through his now semi-liquid enemy. Momentarily confused, Hunter took the time to check again that his enemy was no longer completely solid. Another punch confirmed it, as it wasn't very effective. However, rather than try and think of a way to beat his opponent, he merely kept throwing punches. Each time his attack failed, he grew angrier. Soon he was seeing red again, completely absorbed in beating his already viscous enemy into a pulp. Of course, he didn't even notice the liquid was sticking to him. Eventually, his fists became noticeably stuck, and he could no longer punch easily.

((I am unfamiliar with symbiotes, but from your post and Google I can assume that Casan is now in a rather non-solid form. If I am making a fool of myself, then I will remove this post and educate myself before starting anew))
