I never got the impression that Cloud was emo. I tend to think of being emo as unjustified self-indulgence a lot of the time and I'll be honest, I think the experiences of Cloud are slightly trickier than those of a sixteen year old boy who can't decide which shade of black to dye his hair. There are times in the game when Cloud struggles and does question the nature of his existence to a certain extent, but given the extraordinary circumstances he's in, I'd be quite worried if he didn't.
