The dude is riku ansem/xehanort's heartless form. Thats why he has xehanorts voice. He's talking about sora too. DiZ/ansem the wise sent him to like idk watch him?
In kh1 hollow bastion and alantica. The first time i played KH, i got to HB and once i beat riku, i didnt know how to get to Malificent. Alantica was just annoying.
Kh2 was MUCH easier but xigbar and xaldin pissed me off in my low lvl proud and normal saves.
and mini games in both games. its like jimmny was on *r**** cargo climb friggin 15 secs to do! ugh.
