The Underhive is an area first introduced in Monster Hunter Evolution. It is a large, subterranean cave system that features numerous rivers and ponds of glowing water, giant fungal forests and lakes of liquid tar. The Underhive is home to many monsters that are suited to life in dark, wet environments, such as Khezu, Gigginox, Gypceros, and Tetsucabra. The Underhive is also prime habitat for Neopterans, Carapaceons and Temnocerans as the environment provides perfect breeding grounds for them and as such they are quite common here.

General Description

This areas terrain is composed of many branching tunnels and vast chambers, flowing rivers of glowing water liter many of the tunnels. Much of the flora is composed of numerous fungal species, along with many types of moss and algae. Deadly tar pits are common in this locale and have caused many monsters to loose their lives.

Endemic Wildlife (wip)


  • Shepherd Hare: An animal often seen scurrying down narrow side paths. Follow one and you might discover a new shortcut.
    • Pilot Hare: A rare animal that appears on sunny days. They've been said to guide travelers who have lost their way.
  • Glowtail: An arboreal lizard with wing-like skin flaps, often found near brightmoss, predating on the insects that are drawn to the light of its glowing tail.
  • Vaporonid: An ancient type of spider that spins webs larger in size than humans.
  • Paratoad: A toad that releases paralyzing gas on impact. Its effect is potent enough to paralyze even large monsters.


  • Climbing Joyperch: An amphibian that has retained many of its ancient characteristics. Their songs can be heard during rainfall.
  • Pink Parexus: A fish whose physiology remains almost unchanged from its ancient ancestors. Its spiny fins help ward off predators.

  • Vigorwasp: An insect that collects restorative nectar in its body, releasing it in a cloud when struck.
  • Flashfly: An insect that emits a bright flash when struck, which is brighter when in a swarm. The flash blinds monsters.


  • Candle Snail A large mollusk with glowing spines adorning its shell. The light is used to communicate with its species.
    • Lantern Snail A large mollusk with a blindingly bright shell. The light is used to communicate with its species.


Region 1:

This layer is the closest to the surface and is located near the many openings leading into the Underhive and is one of the few areas where external light from either the sun or moon seeps in through the cracks and openings dotting the roof. Many waterfalls can also be seen leaking into the Underhive here. The terrain of this layer largely consists of a tangled mess of rock platforms interconnected by root and ivy bridges and the occasional waterfall. This is the layer that most of the flying and climbing creatures inhabit.

Region 2:

This layer is located directly underneath layer 1 and is where most of the water from the waterfalls gather to create large lakes filled with bioluminescent algae organisms. The glowing water is where most of the light in this area comes from as the light of the outside world is mostly unable to pierce the veil of roots, vines and stones of layer 1. The terrain of this layer is mainly flat with the occasional rocky outcrop or ledge deviating from the norm. This area is known for the large fungal tree like organism that dominate the landscape like the trees above and the ground is largely dominated by matts of moss and mushrooms but the occasional cluster of ferns can be found growing here as well. The occasional tar pit is found in this area as well. This layer that most of the terrestrial creatures inhabit.

Region 3:

This layer is located even further down then layer 2 and no outside light or bioluminescent pools of water light this layer. The only source of light in this layer comes from hanging blue glowworms and green bioluminescent mushrooms and brightmoss. The terrain is largely composed of long, branching and interconnecting tunnels and chambers. Some chambers contain large lakes of tar filled with ancient skeletons and fossils. Very few large monsters inhabit the cramped tunnels of this layer but some of the most disturbing creatures can be found inhabiting these tunnels.

  1. The reason for the name change was to make the locale more inclusive of other monster types.

BannedLagiacrus' Neopteran Hive

The Neopteron Hive is a never before seen area created by BannedLagiacrus.

This area is unlike any other ever seen before. This area is somewhere close to the Sunken Hollow and under the Everwood, leading to the Primal Forest. This area is ruled by all sorts of insects including Neopterons but also is the nest of the Altaroths, including their queen. This area is also home to different types of bug eaters such as Yian Kut-Ku, Barroth, and Katakana along with some migrational monsters.

Neopteron Hive Map

Base Camp and Zones

The Neopteron Hive has up to eleven different areas in it.

Base Camp

The Base Camp is outside the Neopteron Hive and looks similar to the Sunken Hollow but outside, multiple holes can be seen in the ground below. Coming out of the holes are Altaroth, Bnahabra, and Konchu, exiting and entering the holes underground into the hive. When hunters first leave the camp, instead of jumping or running out of the area, hunters will actually slide down into the first zone.

Zone 1

Hunters slide down from a log filled with honey before entering the Neopteron Hive. When they enter, they can see multiple Anthills built by Atlaroth infront of them and, on the left and right, outside of hunters reach, hunters can see huge plants in the background along with a giant Deviljho Neopteron Trap catching Bnahabra and other insects in its jaws.

Zone 1 connects to Zone 2 and Zone 4.

Zone 2

Zone 2 is wide open has a Felyne Village in it with a Veggie Elder. In the village, they have NH Bee Hives above of them that constantly drip NH Honey.

Zone 2 leads to Zone 1, Zone 11, and Zone 5.

Zone 3

This Zone has steam coming from vents underground and on the floor are many holes. In each hole, a small puddle of slime will rise from the ground before exploding when they turn red.

Zone 3 is connected to Zone 4, Zone 5, and has a short cut to Zone 11.

Zone 4

When hunters enter this area, they will find themselves entering the of center of a large NH Bee Hive. The bees won't attack but will instead buzz around from being disturbed but will eventually leave the area altogether.

Zone 4 connects to Zone 6 and Zone 1.

Zone 5

This area is very similar to Zone 3 but has one difference, a bee swarming on the ceiling.

Zone 5 connects to Zone 1, Zone 6, and Zone 3.

Zone 6

In Zone 6, there are five giant mushrooms that hunters can jump across and on the ground is puddles of poison covering the ground from those mushrooms.

Zone 6 connects to Zone 7 and Zone 8.

Zone 7

When hunters enter Zone 7, they will see multiple mushrooms on the ground along with plants. In this area is a glittering light from the sun and on the walls, Altaroth can be seen moving in huge colonies. In the center of the area, is a huge muddy bog.

Zone 7 connects to no other Zones besides Zone 9 and Zone 10.

Zone 8

Zone 8 is a disturbing seen. Many dead Neopterons are seen here and a large number of them ripped apart by something. Noticeably, hanging from the ceiling is the corpses of Gypceros wrapped in web and near one of the entrances is web-silk den.

Zone 8 connects to Zone 9, Zone 10, and has a short cut to Zone 11.

Zone 9

Zone 9 is a web made by a huge Temnoceran and below the web, hunters can see a huge Altaroth swarm marching down a cliff. Dangling next to web is multiple Gypceros, Seltas, and Bullfango corpses. To reach one of the exits, hunters can actually jump onto those corpses and swing off them but hunters must be careful not to fall into the marching swarm. If they fall into the swarm, it will bring them to Zone 11, their Queen's Lair.

Zone 9 connects to only Zone 8 and Zone 10.

Zone 10

Is very similar to Zone 9 but the web ends with a dead end where the only way to go farther is down. Hunters must jump down a seemingly bottomless pit to go to Zone 11.

Zone 10 connects to Zone 8, Zone 9, and Zone 11.

Zone 11

When hunters land into Zone 11, hunters will see Altaroths crawling down the walls and on the ground, hunters will see the eggs, cocoons, and pupa of the Altaroth laying on the ground. In the corner the Altaroth are wandering in is what looks like royal jelly.

Zone 11 has no exits to other Zones.

  • Deviljho Neopteron Trap : A large fierce plant with a ravenous appetite for Neopterons. These plants will try to eat anything that passes in front of them and if hungry enough they may turn on other neighboring plants.
  • Gypceros Spitter: A fish with a venomous spit that knocks large insects into the water. They are also known to take shiny objects to make small nests.
  • Harpoon Shrimp: A rare cave-dwelling shrimp that is completely blind and hunts for small fish. These bad boys are said to be able to pin two fish down at once.

Slime Mold: In Zone 3, slime will vent out of the ground before turning red and exploding like Brachydios' Slime Mold. Unlike Brachydios', it doesn't cause Slimeblight.

Buzzing: From the buzzing of the NH Bees in some areas, it becomes hard for hunters to hear other hunters on a microphone and it can be very hard to hear if a monster is in another area.

Poisonous Puddles: Due to the giant mushrooms constantly dripping poison, they make puddles in Zone 6 that if hunters step in will immediately poison them. This will slowly drain their health.
