maybe that was riku/an ancestor of riku cuz he/she looks pissed and riku was very pissed in KH1 as for the rest i reckon its sora/sora's ancestors and kairi/kairi's ancestors/some random chick and on this forum somewhere is a pic of one of the dude's face without the helmet and i reckon it looks exactly like sora so check it out if u can find it
