I can't think of a DOA6 character who lacks individuality and flashiness. Everyone is just so well designed and unique. I think more moved would be very welcomed though. The content might be limited, but I'm not bored at all by the roster.
I have no idea what NiCO is talking about in DOA Quest (regarding Diego) : "Such clear brain activity [...] The effect of control by another party? The data doesn't show whether he is aware of if or not".
