Humbaba is first fought alone by Terra when the player first visits Mobliz in the World of Ruin. Humbaba is invincible and cannot be killed. As Terra is unequipped, the player must choose to let her be knocked out. Even if the player uses the Vanish-Doom bug on Humbaba, it will be treated as a loss. After Terra falls, the player's party battles Humbaba in a normal battle. Humbaba flees upon being defeated, leaving the Fenrirmagicite. Though many players choose to travel to Mobliz after recruiting Sabin, they may leave the visit for later in the game.
When the player returns to Mobliz after acquiring the Falcon and locates Terra, Humbaba will arrive for a third battle. When his HP is depleted he uses Humbaba Breath to remove two random party members from battle, and the battle ends. At this point Terra arrives and assists the player in the fourth and final clash with Humbaba. During the fourth battle Terra is in Trance the entire battle and will therefore do great damage. Once Humbaba is defeated the fourth time, he is killed, and Terra rejoins the party.
Though he has four different AI scripts for each fight, Humbaba is offensively the same enemy every battle—it is only his AI script for the end of the battle that changes, his attack script and stats remaining identical. The sole exception is during the second battle where Humbaba's HP increases to 28,000. He attacks with Thundara, Thundaga, his special attack Solar Plex, and 1000 Needles.
Humbaba is weak to Poison, so Bio is highly effective. If Terra knows Bio, she can easily do several thousands of damage to Humbaba in the final battle. Having Sabin equipped with Venom Claws works well, as does having ShadowThrowPoison Rods.
Humbaba appears as a boss in the Mobliz Classic and Elite dungeons in the VI Realm, and has also appeared in several of Record Keeper's time-limited events. He fights similarly to the way he does in Final Fantasy VI, and his 1000 Needles attack does the same amount of damage in both the Classic and more difficult Elite version of the battle. He is vulnerable to Bio spells, but he cannot be afflicted with Poison.
[view·edit·purge]In Akkadian mythology, Humbaba (Assyrian spelling) or Huwawa (Babylonian) was a monstrous giant of immemorial age raised by Utu, the Sun. Humbaba/Huwawa was also the guardian of the Cedar Forest where the gods lived. In the Epic of Gilgamesh, Gilgamesh slays Humbaba for fame and glory.
