Vivi becomes raged, and a battle ensues. After being defeated, Black Waltz No. 3 refuses to accept it is not invincible and commandeers Zorn and Thorn's small airship. It pursues the cargo ship until it loses control of the craft and crashes into South Gate.
Later, Black Waltz No. 3 attacks the train containing Garnet, Marcus, and Steiner, greatly weakened but still seeking to capture Garnet. She attempts to question Black Waltz No. 3 of her mother's intentions, but it blindly attacks and is destroyed at last.
Get out of my way! Do you dare fight a Black Waltz?
—Black Waltz No. 3
The battle begins with Vivi going into Trance. Unlike Black Waltz number two, Black Waltz number three doesn't counter Vivi's spells. Steiner should be using sword magic until he runs out of MP, or toss a potion if needed. Zidane should focus on passing around potions to the injured party member, or focus on stealing equipment off the boss.
Despite the Waltz's use of high level magic (Thundara, Blizzara, Fira), the only tough part is when the Black Waltz is airborne. To prevent this, none of the party members should attack, for this will cause the Black Waltz to fly into the air for some time and deal Thundara spell to all members of the party while also being immune to further normal attacks.
The Black Waltz is more volatile, and its attacks do more damage, but the player cannot lose this battle unless they command Steiner and Marcus to attack and knock out Garnet. This is because Black Waltz No. 3 will never attack Garnet, and if she is the only ally left standing, the boss will inflict damage upon itself. It is recommended that Marcus is kept alive, because this Black Waltz has some valuable items that Marcus can steal, which are useful for Vivi later on; plus, it helps add damage to Zidane's Thievery skill acquired later.
One of the elite black mages who serve Alexandria. It looks down on all creation as it sees destruction as the only purpose for its existence. It will go to any length to do its duty, a mad light dancing in its eyes...
