Humbaba, also known as Huwawa and Humbaba the Terrible, was raised by the Sun God Utu. He was a giant tasked with protecting the home of the Gods, known as the Cedar Forest, by Enlil. Eventually he was tricked by Gilgamesh who offered his sisters to him, resulting in his capture. Humbaba's attempt to escape ends with Enkidu slaying him. Enlil then redistributed the seven splendors/auras of Humbaba to seven others, such as the Lions and the rivers.
Known as Humbazom, it can be created through Relic fusion using the Wafer+Demon+Heavy, Fear+Demon+Talon, or Air+Demon+Tusk combos.
"One-eyed demon who watches over the woods and will attack any who seek to harm it."
—DemiKids Demonary
Known as Humba, he has the power Final Wall. Humba can be revived from Humbazom once his soul is obtained.
Persona Q2: New Cinema Labyrinth
Phunbaba is one of the new F.O.Es encountered outside the Cinema. It appears as a large, black and yellow robotic guard resembling a bipedal Dragon. It is a security guard deployed by Enlil and has no free will on its own.
The F.O.E. turns aggressive the moment the party enters its line of sight and moves up to two spaces at once. However, it will only do so every two player steps. If it comes across any rubble while chasing the party, it will halt its movement and take a step to destroy the rubble. This not only opens up more paths for exploration but can be used to create space between it and the party. The F.O.E. will move back to its resting spot if the party escapes it.
Defeating this F.O.E. for the first time will yield the Destroyer's Disk, which unlocks the special fusion for Shiva.
Phunbaba being able to be lured into smashing down roadblocks might be a reference to the Cutter F.O.Es in Etrian Odyssey IV, which have to be baited to destroy obstacles in order to progress through the labyrinth.
