Personality

Zack's an overall loud caring person. He likes money. (Who doesn't, in all actuality.) He's the second in command to Sephiroth, whom he was 'War Buddies' with. (I'm not talking sick here, mind you.) He became friends with Cloud too, whom was at the time nothing more than a Shinra guard. From Aeris's opinion, he apparently made friends (And girlfriends) rather easily.
