Undertown

A town for aliens underground

The Plumbers are an intergalactic law-enforcement organization that makes use of many high-tech gadgets and weapons to protect the planets in the universe from various alien threats and attacks.

Pyronite: Pyronites are humanoid plasma-based beings composed of a bright inner plasma body encased in volcanic rocks. Due to their fiery nature, their bodies radiate intense heat. Their feet have a distinctive oval shape with only two main toes and a smaller back toe. Pyronite infants are smaller and thinner, while children have larger heads and higher-pitched voices. Female Pyronites share similar physical attributes with males but have more curvaceous figures, slightly protruding chests, and thinner arms. Their faces are longer and more rounded. Pyronites primarily exhibit colors like yellow, orange, or red, though some individuals may be blue (often due to Earth cold virus infection) or even white.

Vulpimancer: Vulpimancers are animalistic beings with canine paws, curving claws, and quills that grow on their backs. Their most notable feature is that they have no visible eyes, and instead have gill-like nostrils on the sides of their necks. A Vulpimancer's size ranges from an adult human to several times larger. As they mature, they grow tails. Vulpimancers commonly have orange fur, though they can come in other colors such as greyish blue, yellow, red or brownish red. As they reach adulthood, Vulpimancers gain stripes on their backs. Some Vulpimancers from Vulpin have dog-like mouths with matching teeth and tongues, whereas others have more unearthly mouths with worm-like tongue, chapped lips, and four large fangs. Young Vulpimancers have quill-like fur, which becomes straighter when they mature. This excludes the chin hair on Vulpimancers from Vulpin.

Petrosapien: Petrosapiens are made of a super-hard, green/blue diamond-like material. They are a little taller than humans. They have four digits on their hands and none on their feet. Male Petrosapiens have a spike on the back of their semi-cubic head and two to six on their back with thicker, blockier arms; females have smooth flat-top heads.

Kineceleran: Kinecelerans have blue faces and skin. They have long, prehensile tails that may or may not have black stripes on them. Their arms end in three fingered hands. Their feet have wheels on them, which enables them to travel quickly. They have white eyes (although XLR8 has green ones due to the Omnitrix). Kinecelerans have masks which can cover their faces. They appear to wear helmets, which are usually black, long, elliptical, and pointed at the top. These are made up of their skin and part of their skull. Some Kinecelerans have claws instead of fingers.

Tetramand: Tetramands are a buff and bulky species. Most Tetramands are red, but blue and brown ones have been seen. Tetramands have spikes on their arms, and sometimes on their heads. They have two front toes on each foot. Tetramands appear to have an additional set of smaller pectoral muscles below their primary set to help move their second set of arms. Each one of their four hands has three fingers and a thumb. They also have four eyes. Female Tetramands have hair. Male Tetramands have hair that turns gray as they get older, but most of them lack hair. Younger Tetramands are skinnier than adults and have disproportionately larger eyes and heads.Tetramands have an average height of 10 feet and can grow to be as tall as 15 feet high. Female Tetramands are usually taller than the males.

Galvan: The Galvan are a species of small bipedal frog-like amphibians. Galvan are about six inches tall on average. Their bodies consist of soft and flexible bones, allowing them to squeeze into tight spaces or quickly escape from danger. Unlike humans, the Galvan have large, bulbous eyes with rectangular pupils. They have two sets of eyelids, which close vertically and horizontally, respectively. Normal Galvan have green eyes, except Albedo, who has red eyes (as his colors were inverted).

Lepidopterran: The Lepidopterrans are an insectoid species with four insect-like pincer legs and two arms with hands consisting of three clawed fingers. They have four pupiled eyes that grow out on stalks as pairs on each side of their head.Their wings are very thin and fragile, with vein lines and a holey, two-pronged shape. They have tails that end in an armored, stinger-like growth. Infant Lepidopterrans have large eyes and much smaller wings and tails. Their bodies also appear fatter. Adult male Lepidopterrans have more muscular eye stalks, larger tail stingers that curl at the tip, and much larger and wider front legs.

Pisciss Volan:Piscciss Volanns have multiple gills and an antenna on their heads for deep-sea diving. When young, their teeth are external, but they become internal as they get older. Their bodies are covered in protective scales with claws on their appendages. The female Piscciss Volanns look exactly like males.

Galvanic Mechamorph: Galvanic Mechamorphs are a techno-organic species with a gel-like body composed of small cell-like creatures called nanites. They have a green color scheme and have one cyclopean eye in the center of their face. Their bodies are covered entirely in a circuitry pattern that can vary from Mechamorph to Mechamorph. A Mechamorph's eyes can change shape depending on their emotion, such as pointing downwards in feelings of anger, or upwards in feelings of sadness or surprise. Galvanic Mechamorphs can come in a variety of forms, some of them resembling animals, and some appearing as trees and other plants. They can also be thin, tall, robust, wide and even more "obese".

Ectonurites: With their outermost layer of skin, Ectonurites look like a classical ghost with a track for their eye to travel upon. Without their outermost layer of skin, Ectonurites look like misshapen horrors. They possess an exposed skull with sparse teeth for a head, only one eye, dark blue skin, exposed bones on certain parts of their bodies, black claws, a big gaping hole in their chest with black and white striped tentacles hanging out, and speak with an eerie, creepy voice. Ectonurites can rotate their heads so they can be upside-down or the right way up.

Loboan: A lycanthropic form of Ben with enhanced strength and senses. Loboans, like Benwolf, typically have grey or brown fur, sometimes with a long flowing mane and a bushy tail. They possess three or four sharp claws on each hand, with one serving as a thumb. Their elbows and shoulders are often spiked. Loboans have unique four-hinged jaws that can open outward, and their mouth interiors can be purple, green, yellow, or red. While most have grey or brown fur, some Loboans are distinguished by their white fur.

Methanosian: Methanosians are a humanoid plant-like alien species with green and black colored bodies encrusted with muck. Their feet are root-like and have black toes resembling rocks. Their shoulders and heads are adorned with red and yellow petals. Methanosians can either have four or five fingers. Methanosians are taller than an average human and have a distinct rotten stench that worsens with heat. So far, only male Methanosians have been seen, so it is unknown what female Methanosians look like. Before they hit puberty, they have black faces and their petals and facial structure are different.

Sonorosian: Sonorosians are white humanoids made of silicon. Though they resemble robots, their bodies are natural. The green, circle-shaped indents on the backs of the hands of Sonorosians are sound holes, which help them resonate. They also wear headphones so they would not be hurt by their own sonic screams. Sonorosians speak with voices resembling a vocoder synthesizer.

Vaxasaurian: Vaxasaurians are a humanoid dinosaur-like species, being beige in color. They have human-like hands with four fingers, each with large gray nails. They have long dinosaur-like tails. When they grow, the Vaxasaurians' dinosaur features become more pronounced, growing Stegosaur-like plates on their back, a crest on their forehead and spikes on their tail. Also, on their shoulders, three plates separate and grow. Female Vaxasaurians look like males, but wear bones and a big loincloth, much like that of a caveman.

Crystalsapien: Crystalsapiens are silicon-based lifeforms made of highly durable crystal. Most of their bodies are covered in a protective silicon-based rock, while the exposed crystal is magenta. They have purple bodies, legs and arms with several black lines and dots on them. They also sport magenta shards all over their body: six on their back, two on their chest and one on top of their small, purple head, resembling a horn. They also have one large, cyclopean eye.

Arachnichimp: Arachnichimps are blue colored, monkey-like aliens with four arms, four or six eyes, and two legs. They also have three fingers on each hand and three toes on each foot, blue fur over a dark blue center, and a tail with some striped fur. In Alien Force and Ultimate Alien, Arachnichimps had two sets of eyes. The top 2 were smaller than the bottom 2; they were yellow with black pupils; and infant Arachnichimps had even larger lower eyes than normal. In Omniverse, Arachnichimps now have six eyes, arranged in one grouping of 3 on both sides of the face, that are pure black. Their nostrils are also located higher on their face. Like humans, Arachnichimps can have different styles of head hair.

Necrofriggian: Necrofriggians are humanoid moth-like species with four wings and two antennae-like wing folds, which fold up into a poncho-esque robe with a hood, giving them the appearance of a phantom. They have black bodies with patching on their slender chests, running along their legs and arms, the latter reaching up to the back of their necks. On those leg and arm patching are cyan patches that resemble large ice chunks. Thick black lines border the back-end of each wing, which also contain three cyan patches of their own. Necrofriggians' faces have harsh black lines surrounding their eyes and mouth, which all meet at the center of their face. They also have a black marking on their head that extends over their scalp; forcing the remaining colored parts of their forehead into a Y-shape. Their eyes are bright, and have smaller darker spots inside. Their mouths are frowns, showing four bluish-white teeth, which rarely move, even when speaking. They have three pointed fingers and a thumb on each hand, and three toes on each foot: two in front and one behind. Necrofriggians from Kylmyys have skin and wings that are a dark blue. Necrofriggians from Mikd'lty have skin and wings that are a much paler shade of blue. They also have bright blue eyes. Sometimes Necrofriggians have a much more muscular build, with long black hair draped over the top of their large chests. large eyebrows and sharper ears. They have bigger wings, claws, and additional brows around their eyes.

Polymorph: Polymorphs are unicellular organisms that weigh around 200 pounds, and are neither liquid nor solid, but colloidal suspensions. Polymorphs are generally green in color, though they do come in different colors, including red, mint green, blue, orange, yellow, grey, purple, peach and pink. Polymorphs are gelatinous humanoids with a pointed head and an asymmetrical, drippy amoeba-like shape. Their brains are spread throughout their body.

Appoplexian: Appoplexians are tiger-like humanoids with huge muscles. They have orange fur, white muzzles, hands, stomachs, chests, and feet. The fur can also vary from yellowish orange to dark orange and the white parts can occasionally be light yellow. They also have black stripes on their head, shoulders, back, and legs. Sometimes there are also stripes on the forearms, cheeks, or chin. There is a chance that the head supports a Mohawk, being either the color of the muzzle or stripes. They have a large, single retractable claw coming out of both wrists that can be either black or dark metallic blue. Instead of keratin, the structure of the claw is mostly pure bone. Since Appoplexians have a high sense of shame, they are mainly seen wearing sleeveless vests, short or torn cargo pants, either gauntlets or straps, and a metallic belt containing an orange squared symbol with black stripes on each side. Although most Appoplexians have orange fur, some of them can have white fur if they just evolve in colder climates.
