Well Supa I did say "similar" and its definitely not nercrodermis. Could it be some form of nanobots or thet are bio-mechanical? As for what role they may play well I'll think of something. Maybe once in a while one/few Titan may get over his blood-lust and attack someone else? P.S. I will probably adopt this.
