The way I play my HoX is I take his emotions to the extreme. Sometimes he is extremely noble and good, other times he is full of malice and spite, and maybe sometimes he is extremely loving and other times extremely hating. It really differs, I also put two conflicting emotions in him at times like extremely noble/loving towards one and spiteful/hating towards everything else maybe even the same guy... and yea he is a madman I guess

But its fun. I never know what to expect and neither does the ones I meet.
