Demogorgon (ST Species)

* Stage Six
* Stage Five
* Stage Four
* Stage Three
* Stage Two
* Stage One

**Demogorgons** are predatory creatures originating from the Upside Down. All Demogorgons encountered thus far are assumed to obey the Mind Flayer, and make up part of his hive mind. Under his influence, Demogorgons are murderous, violent and have limited intelligence.

In 1983, a fully grown Demogorgon set foot in Hawkins, Indiana after a gateway to the Upside Down was accidentally opened. This Demogorgon was eventually defeated and destroyed, but not before it could inflict damage upon the human world. Will Byers, a rescued victim of the Demogorgon, became a vessel for the Mind Flayer. Somehow, Will's possession allowed the Mind Flayer to unleash a swarm of adolescent Demogorgons upon Hawkins.

The **Russian Demogorgon** is a sixth stage member of the Demogorgon species that is being held captive deep within the bowels of a Soviet Gulag in Kamchatka.

One was summon by Chimaura in Undertale: Master Reign to do his bidding and later bow down to Green Stripes in Undertale: Hell Supreme

## Story

### Life cycle

The life cycle of a Demogorgon seems to have six distinct stages and is similar in some ways to that of several Earth amphibian species.

In the only cases of Demogorgon reproduction observed, the cycle began with the deposition of eggs or larvae within a host by a tentacle within the Upside Down. The slug-like larvae later were vomited up by the host, and subsequently escaped into the wild. After this, the larvae underwent a period of rapid metamorphosis, molting through each phase of their development until emerging as an adult. The process takes place over the span of a week. A Demogorgon's life cycle was best illustrated by Dart, a Demogorgon which Dustin temporarily kept as a pet.

### Stage 1: Slug

Larval Demogorgons are roughly the same shape and size as the standard garden slug, but they differ in terms of coloring. Larval Demogorgons are generally dark green, with bright yellow spots.

The larvae inhabited the bodies of the original Demogorgon's victims:

* Will Byers: Will was found in the Upside Down with a tendril extending down his throat following his capture by the original Demogorgon (see Stage Six below). A month after returning home, Will coughed up a larva and washed it down his bathroom sink drain. It is probable that the tendril 'impregnated' Will, so to speak.
* Barbara Holland: While immersed in the Void, Eleven scoured the Upside Down to find Will and Barbara. She discovered Barb's corpse and saw a larva slither out of Barb's mouth and across her face. This particular Demogorgon was know as the slug like creature.

### Stage 2: Pollywog

After an unknown amount of time, a larval Demogorgon would molt to the next stage of its life cycle, sometimes referred to as a “pollywog” due to the resemblance to the larval stage of amphibians. The pollywogs are small enough to fit in the palm of a hand, and their translucent skin is colored yellow-green. They possess a pair of forelimbs with small claw-like hands, a mouth, and a lizard-like tail. They are incredibly sensitive to heat; even direct exposure to the light of a table lamp is enough to cause a pollywog extreme discomfort. During this stage, they appear to be opportunistic feeders, as Dart was found foraging for food in a trashcan and ate a candy bar it received from Dustin.

### Stage 3: Frogogorgon

Unlike other stages, the third stage of the cycle is not entered by the creature molting. Instead, this stage is signaled by the pollywog's skin taking on a dark green color, as well as an increase in body mass. The pollywog will then sprout a pair of hind legs, becoming quadrupedal. Small, sharp teeth begin growing in the creature's mouth.

### Stage 4: Catogorgon

Once the pollywog has eaten a sufficient amount of food, it molts, growing a little larger than a standard house cat. It is in this stage that the juvenile Demogorgon develops the signature “petal mouth” that the species is best known for. In addition, the juvenile becomes carnivorous. Its skin takes on a darker color and is resistant enough to heat that it is able to walk in direct sunlight with no injury.

### Stage 5: Demodog

Upon molting to the penultimate stage of their life cycle, the adolescent Demogorgon develops to a much larger version of their previous form, which Dustin referred to as a “Demodog”. Now roughly the size of a large dog, the Demodog is strong enough to tackle a grown human. They are proficient in digging tunnels and are able to climb steep precipices. While a Demodog is not invulnerable to gunfire, its skin is thick enough to resist several gunshots.

### Stage 6: Demogorgon

After molting for presumably a final time, the Demogorgon emerges as an adult. Adult Demogorgons are bipedal and reach a height of approximately 6 - 10 ft. They possess immense strength, being able to knock a door off its hinges and pin down an adult human with ease. Their sense of smell is exceptionally potent, being able to detect a small amount of blood even while in another dimension. Their skin has grown durable enough to withstand gunfire and numerous attacks dealt with a spiked object. One of the few things shown to cause a Demogorgon any type of significant harm was being burned, but even then the creature was able to escape fairly easily and did not seem to be hindered by its injuries.

The Demogorgon that plagued Hawkins in 1983 could open inter-dimensional portals and appeared to possess limited telekinetic ability. It is unknown if all adult members of the species possess these abilities, or if they were somehow exclusive to that individual. It is also unclear whether or not this individual was under the control of the Mind Flayer. Another Demogorgon was kept in a Soviet gulag in 1985, in order to devour political prisoners.

## History

### Stranger Things Season 1

A test subject with psychic powers labeled Eleven was placed into a sensory deprivation tank as one of Hawkins National Laboratory's experiments; this allowed Eleven to delve into a deeper psychic state. Although she successfully eavesdropped on a Russian spy as instructed, she unwittingly came across the Monster. Eleven's instincts urged her to stay away from it; she panicked, and the experiment was aborted.

Dr. Martin Brenner was intrigued by the creature, repeating the experiment on November 6, 1983. This time, Brenner ordered Eleven to make contact. As Eleven psychically approached the Monster, she could see it feeding off an otherworldly egg. With great hesitancy, she made contact. In that exact moment, a gate to the Monster's dimension cracked open in the wall of the tank room, allowing the creature to pass through. Eleven managed to exit the tank and escape the lab amidst the ensuing chaos. An unnamed scientist was not so lucky; the Monster caught him as he tried to operate an elevator.

### 1983

The Monster had the ability to travel between dimensions on a whim, creating temporary portals in the fabric of reality. The Monster arrived at Mirkwood, a road near a local forest, where it stalked Will Byers on his way home. The Monster chased Will as he entered his house, forcing Will to run to his garden shed. Will hid in the shed, loading a rifle in self-defense, but the Monster simply appeared behind him, taking him into the Upside Down.

Once in the Upside Down, Will managed to evade the creature for almost a week and began attempting to communicate with his mother. Joyce and Will had some success, with Will manipulating the electricity in his home dimension, although these attempts would sometimes attract the monster. In an early attempt, Joyce saw her house wall become warped and distorted as the Monster started to break through, terrifying her. In a later attempt, the Monster broke clean through, although Joyce managed to outrun it.

Meanwhile, Will's friends Mike, Lucas, and Dustin began investigating Will's disappearance. Mike noted a strange coincidence linking the disappearance with a recent "Dungeons & Dragons" campaign. During the campaign, Will's player character was defeated by the fearsome Demogorgon; hours later, Will had vanished from real life. In addition, Eleven used the game piece representing the character to attempt to illustrate her vision of Will hiding from the creature in the other dimension.

The group began to hypothesize that the Monster may have really existed, and was responsible for Will's disappearance. From this point on, the group began referring to the creature as "the Demogorgon".

Scientists at Hawkins Lab began investigating the dimension, discovering exactly what it contained. One such scientist entered through the Gate, wearing a hazmat suit linked to a chain rope. The scientist was savaged and killed by the Demogorgon almost immediately after entering the dimension. The Demogorgon hunted and killed other people and creatures, being particularly lured by blood. Its victims included Barbara Holland, hunters Dale and Henry, and a wounded deer. After Nancy Wheeler entered the Upside Down through a temporary portal, she observed the Demogorgon as it feasted on the deer. The Demogorgon noticed her, chasing her until she returned through the portal.

Will eventually succumbed to exhaustion, lying in his makeshift fort. The Demogorgon found him, breaking through the fort wall and taking him to the Upside Down library.

Nancy and Jonathan Byers later exploited the Demogorgon's attraction to blood to ambush it. With the aid of Steve, they severely injured the beast, setting it alight - however, it survived and slipped into the Upside Down. The Demogorgon left the Byers house and headed to the library, leaving a trail of blood.

Eleven killed a large number of government agents at Hawkins Middle School, defending herself, along with Mike, Lucas, and Dustin. The Demogorgon was attracted by pools of spilled blood, breaking through the wall. The Demogorgon began a spree of violence, attacking Dr. Brenner as surviving agents opened gunfire.

For a while, the four kids outran and evaded the creature, hiding in their science teacher's classroom. Eventually, the Demogorgon found them, breaking into the room and attacking them. Eleven confronted the creature, pinning it against the blackboard with her mind. After wishing farewell to her friends, she proceeded to disintegrate the creature, vanishing as well in the process.

### Stranger Things Season 2

When returning home after trick-or-treating, Dustin heard a noise coming from the trashcan. Upon investigating, he discovered a creature and placed it in his ghost trap. Dustin placed the creature in his tortoise's tank and fed it a Three Musketeers bar, appropriately giving it the name D'Artagnan after the character from the novel.

The next day, Dustin brought Dart to school, showing it to Mike, Will, Lucas, and Max. After discussing what type of animal Dart could be, Dustin concluded that he had discovered a new species. However, after noticing it resembled a slug he had thrown up the year before, Will realized Dart originated from the Upside Down. Before Dustin could show Mr. Clarke, Mike took Dart and urged everyone to meet again in the AV club room, excluding Max. When Dart started to emit a screeching sound, the boys opened the proton pack to witness it grow a pair of hind legs. Mike then tried to attack Dart, which caused it to flee and run loose throughout the school. Will eventually found Dart in a bathroom; it screeched, causing Will to run away. Soon after, Dustin arrived to retrieve Dart. When the others arrived, Dustin hid Dart under his hat and lied saying he had not seen it or Will.

Dustin then brought Dart home, and continued to care for it secretly while keeping up the appearance of looking for it with the others. After returning home from school, Dustin found that it had broken out of the tank and eaten the Hendersons' cat, Mews. Realizing Dart was now dangerous upon seeing how it could open its mouth like the Demogorgon, he lured it into the storm cellar and called in Steve to help exterminate it. However, Dart escaped, forcing Dustin, Steve, Lucas, and Max to lure it to the junkyard in a final bid to kill it. Dart soon arrived but was joined by several other creatures of its species, which started to attack the group until they were called to Hawkins Laboratory by the Mind Flayer.

Dart was not seen again until the group were trying to exit the tunnels underneath the pumpkin patch, when they were stopped by it blocking their way. Recognizing Dustin, Dart did not attack and was easily distracted by Dustin giving it another Three Musketeers bar, allowing the group to escape. Dart did not join the other Demo-dogs in returning to Hawkins Laboratory, and was ultimately killed when Eleven closed the Gate to the Upside Down.

### Dimensional Rift: Strange Beings

Somehow, Dart survive and was reveal that he went into a cocoon stage to survive and was a fully grown Demogorgon. After encoutering the party and a Xenogorgon, Dart tackle the Xenogorgon and chase it off, only to find in his home, the Upside Down. Dart join the others to chase and attack the Xenogorgon's hive only to be tackle and killed by one.

### Dimensional Rift the Series

In S1 Ep1, one appear before Kyana and attacked her as Dr Brenner came in and save her later on. Killing the beast. James and Spitter later on found the Demogorgon body and Spitter was eating bits of pieces off it as James was looking around at the scene of the crime.

### Stranger Things Season 3

After pulling a prisoner out of his cell, two Red Army Soldiers sacrificed a political prisoner to the beast.

### Undertale: Master Reign

The Demogorgon was one of the monsters that was summon by Chimaura after he stole the title.

### Undertale: Hell Supreme

The Demogorgon reappear again as it was eating a Unknown Monster's dead body in daylight. However, when the Demogorgon (D&D) showed its face, they battle it out. A few moments later, it was revealed that the Demogorgon (Stranger Things) won the battle against the other Demogorgon. When James and the rest travel back in time and lost the title again, Chimaura summon the monsters again but after that, Green Stripes used his alpha call to call the monsters to Mt. Ebbot as Green Stripes battle Chimaura for the title again and wins. Demogorgon was the first creature to arrive to witness Green Stripes' win and the last to bow to the King of the Dimensions. It later on return to its' dimension.
