Pap

The Papu (バプ, Bapu) is a mysterious human feeding beast and one of the Five Great Calamities that humanity met in the Dark Continent.

Appearance
The Papu's appearance is still unknown. It seems to be able to sprout feelers which it inserts in the skulls of its human victims.

Background
When the allied nations of Hekerose send 1000 people into an expedition to the Dark Continent, they went through the north of the Mobius lake, and secured a route inside the rugged mountains. There they found a rare mineral called "Ghost Stone" that once submerged in water, even with one small bead, it can generate 20,000 kilowatts of power for one entire day. But unfortunately for them that zone was also the territory of Papu that decimated them effortlessly leaving only seven survivors.

Abilities & Powers
Not much is known about the Papu's abilities, but according to Ging Freecss its threat level is either A or B, like that of the other Five Great Calamities. The current Chairman of the Hunters Association, Cheadle Yorkshire, proclaimed that their danger rank has been raised from B to A, which is even higher than that of the Chimera Ants.

Although unconfirmed, it is possible, due to the serene expression on its victims' faces, and its full title reading "pleasure and life exchanging human feeding beast Papu", that Papu puts its prey in a state of extreme bliss while it saps away their life.
