Kefka appears as a cinematic enemy on three occasions that cannot be fought by the player. The player fights Kefka twice as cinematic sequences rather than actual battles, in which Kefka uses his field sprite rather than his battle sprite, and both battles end whenever Kefka is damaged in any way, meaning his stats go unused. In addition to the boss fights, a boss enemy called "Kefka" can be found hidden within the data. As the enemy cannot be naturally fought within game, it is a dummied enemy. It shares its sprite with the Guard enemy, likely due to the fact the Guard is the first enemy in the game and the sprite wasn't changed.
Kefka's level, HP, and MP will vary depending on the party's level. The higher the party's level is, the high Kefka's level, HP, and MP will be when fighting him in the Imperial Camp. He comes equipped with a Morning Star, Mythril Helm, Mythril Vest, and a Ribbon permanently equipped. The only thing that Kefka does in battle is physically attack Sabin and Shadow (if the player recruited him) with his Morning Star. Damaging Kefka once will end the battle.
Kefka's level, HP, and MP will vary depending on the party's level. The higher the party's level is, the high Kefka's level, HP, and MP will be when fighting him in the Cave of the Sealed Gate. He comes equipped with a Morning Star, Mythril Helm, Mythril Vest, and a Ribbon permanently equipped. Kefka has a better battle script compare to his last battle in the Imperial Camp. After Kefka has taken enough damage, the battle will end. The player can simply use a Smoke Bomb to end the battle. They can escape by using a Smoke Bomb only, as the shoulder buttons are disable.
As the battle is easy Kefka often never has a chance of using his special attack against the party. When Kefka uses his special attack, called Hit, the special attack's name does not appear in the textbox, as it will be blank (See Blank special attack bug). Kefka's special attack won't hit the target, so the player will never see the effect of his special attack.
The dummy version of Kefka's AI script implies that the enemy was a device used to help switch the tiers in the final battle. However, since the enemy does not actually appear in the final battle, the enemy is a dummied enemy.
