Khezu is a Flying Wyvern introduced in Monster Hunter. It is known to inhabit subterranean areas and can be encountered at Low, High, and G Ranks.
Khezu are large, pale Wyverns with a flabby, rubbery hide which is constantly kept damp, similar to that of an amphibian. Many of their blood vessels and veins can be seen through their pale skin. Their tails feature a specialized orifice which bonds to the ground during electrical attacks and helps them cling onto cave ceilings, and their mouths feature rows of sharp teeth. Khezu feet lack claws, and instead have suction pad-like toes to assist them in climbing and hanging from cave walls and ceilings. Spending most of their lives in the dark, Khezu's eyes have regressed greatly, though they make up for this with a superb sense of smell. A layer of fat helps to keep them warm and prolong the time they can spend hunting for food. Khezu have extendable necks which allow them to grasp and ambush prey from afar, such as from a cave ceiling. Khezu are hermaphrodites, which means an individual is both male and female. To reproduce they paralyze a creature and inject their young, known as Whelps. The Whelps grow inside their victim until it dies, or when they are strong enough to leave.
Although Khezu are cave dwellers, they go out when they please, or when food inside grows too scarce. While a Khezu outside a cave is vulnerable to larger Wyverns like Tigrex, inside caves the Khezu has the advantage. In addition to being unhampered by the dark, they can cling to the ceiling and attack from above.
The Khezu's habitat is often located near active sources of water; some sources claim this is because the water is excellent for conducting electricity into their prey, while others speculate that the Khezu may need the dampness for its moist skin. Such areas include the Swamps and Frozen Seaway.
Other Non-Subspecies Forms
Hard Core (HC) Khezu
HC Khezu was released, with new attacks; it can now fire multiple ground lightning balls that scattering widely, and fire ground lightning balls upon landing. Sometimes it also covers itself in electricity after performing an electrical ball attack. Finally, it also has another roar, which is much shorter than the first one but paralyzes Earplugs-less hunters for a longer time.
HC Khezu appears to have brownish color on certain parts of its body and big blue veins. It also has new attacks and behaviors. It can create an onslaught of electricity that fatally paralyzes any hunter caught in it while generating short bursts of electricity on its body at the same time so no one will come close. It has been seen that it will perform a new screaming behavior where it rises up tall and screams fast to stun hunters, then quickly performs its shock wave, leaving no escape for the unprepared.
One of its most confusing attacks may be when it hovers with a thunder ball in its mouth around a targeted hunter then releases it with pinpoint aim upon landing with a electric barrier at the same time.
A Khezu's tail has a suction-cup-like mouth with teeth in it. They use this to attach themselves to cave ceilings, and to ground themselves when performing an electrical attack.
As shown in the Ecology video, the flabby hide of a Khezu is covered in a thin, wet liquid-like membrane. Its purpose is unknown.
The saliva of a Khezu has strong acidic properties that can melt the floor of caves and damage hunters.
Khezu are one of the few (if not the only) Wyverns in the Monster Hunter world that do not activate the "Yellow Eye" debuff on the Hunter. This could be considered a disadvantage due to the fact that it does not allow a Hunter to do a panic dive to avoid attacks. No background music plays, even for sidekick monsters, e.g. Giadrome.
In the Khezu Ecology cinematic, it is seen preying on a Kelbi.
The Village four star quest called "Fang of the Iodrome!" a Khezu appears in it. If you fight it, it has an interesting glitch, unlike any other Khezu on MHF1 this is the only one to have background music playing for it.
The Khezu gained the ability to leap out at the hunter while generating its signature electrical field.
It gained a thunder bite, and an improved thunder blast where it shoots out more thunder balls than the normal move; this is highly predictable because a bolt of electricity runs across Khezu's mouth when charging the attack.
There are Quests that requires the Hunter to slay or capture tiny Khezus. These Khezus are perhaps Khezu Whelps who are strong enough to leave the carcass in which they were born. The tiny Khezus have a high pitched voice, due to their miniscule size. Their roars are notably shorter, and leaves the hunter incapacitated a bit longer.
When enraged its veins will begin to throb.
When low on stamina it will fail to shoot its lightning balls, produce its lightning shield, and recover from attacks.
Its face, wings and body can be broken and scarred.
