Humbaba (Final Fantasy VI)

Phunbaba is a boss enemy the player encounters twice in the second half of Final Fantasy VI.

In the Game
In the World of Ruin Phunbaba is a vicious monster who prowls the Mobilz region and terrorizes orphans who live there. Terra Branford befriends these orphans after being separated from the party because of the unbalancing of the statues. The player first runs into it in Mobilz where it easily defeats Terra, leaving the player to fight it with the party of Celes Chere and Sabin Figaro. Upon defeating Phunbaba, the player receives the Fenrir magicite. The player has the option to return to Mobilz later in the game where they must face Phunbaba again, finally killing it, and making the town safe for Duan and Katarin to raise their newborn child. Upon defeating Phunbaba this time Terra finally decides to rejoin the party.

The Epic of Gilgamesh
Phunbaba takes its name from a demon, Humbaba or Huwawa, in the Epic of Gilgamesh. Humbaba is a giant with the face of a lion who gaurds the Cedar Forest where the gods resided. Gilgamesh and his partener Enkidu travel into the Cedar Forest to find and kill Humbaba. Before he died he begged Gilgamesh for mercy, who almost acquiesced, but was convinced otherwise by Enkidu
