Battle Meter is a menu element in Final Fantasy VIII that keeps track of battle stats. It can be viewed in the Information subsection of the Tutorial section of the menu.
Battle Meter records the won and escaped battles in the information section of the menu under "Tutorial". It is obtained by talking to Headmaster Cid Kramer in his office after the party's inauguration into SeeD. If the player does not get it then, they can still talk to Cid in his office after the Timber Mission briefing, but they must do so before boarding on the train for Timber, otherwise the meter is missed and they cannot get the enhancements for it either.
The Character Report keeps track of the numbers of kills and KO's per character. It is given by a prisoner on floor 10 of D-District Prison. The player must have obtained the Battle Meter first. Because the prison is an unrevisitable location, they only have one chance of getting it.
The GF Report keeps track of the numbers of kills and KO's per Guardian Force. It is given by CC Joker in Balamb Garden's training center. The player must have obtained the Battle Meter first. CC Joker appears randomly in the rightmost area of the center. This report can be missed too if the player fails to get it from CC Joker before reaching the point of no return towards the end of the game.
