Calcabrina (Final Fantasy IV 2D)

The Calbrena is an enemy from the game Final Fantasy IV. It appears during the battle with the Cals and the Brenas after a certain amount of time passes and the enemies don't die. If this happens, the Cals and the Brenas will leave and the party will have to battle the Calbrena. It can be particularly dangerous because it uses Glance to Charm a character. If the Calbrena isn't defeated within a certain amount of time, it will revert to the Cals and the Brenas with all their HP.
