The original Battle Meter records the won and escaped battles in the menu and is given by Headmaster Cid Kramer after inauguration into SeeD in his office. If the player doesn't talk to him during this, the meter is missed and the player can't get the enhancements for it either.
The Character Report keeps track of number of kills and KO's per character. It is given by a prisoner in floor 10 of D-District Prison. The player must have the Battle Meter first. Because the prison is an unrevisitable location, the player only has one chance of getting this.
The GF Report keeps track of number of kills and KO's per Guardian Force. It is given by CC Joker in Balamb Garden Training Center. The player must have the Battle Meter first. CC Joker appears randomly in the rightmost area of the center. This report can be missed too.
