Nanaki. Ok, Aeris' death made me shed a couple of tears the first time. On the 22nd play through, Nanaki seeing Seto and howling still made me cry like a baby. Everything about him is just awesome, he's intelligent and determined, and he's about the only character aside from Barret who we see with with genuine love for someone other than a main character. (Although Cid DOES love Shera, and I DO love Cid.) But Nanaki's affinity ith Buugenhaagen is wonderfully done, and he's oddly enough one of the most believable characters for me.
