Upside Down (Other Dimension)
The Mind Flayer
Stranger Things series
The history of the Mind Flayer prior to October 1984 remains a mystery. Exactly how long he had existed for, and how and why he came into existence, is unknown.
In November 1983, an inter-dimensional gate was opened at Hawkins Lab, allowing the Upside Down to begin to spread through. It is not known if the Mind Flayer was present within the Upside Down at this time.
Will Byers, a young resident of Hawkins, was captured by a Demogorgon and brought to the Upside Down’s version of the town’s public library. Although he was safely recovered by friends and family, Will began to have visions of the Upside Down.
Will continued to have visions of the Upside Down for a year following his rescue. These visions were examined by Dr. Sam Owens at Hawkins Lab, who believed Will was experiencing post-traumatic stress disorder.
On October 29, 1984, Will and his friends went to play at the Palace Arcade. While his friends argued with the arcade’s employee, Will became distracted by another vision. He walked out of the Upside Down version of the arcade. To his horror, he witnessed a blood-red storm raging in the sky above, before hearing an unearthly howl. However, Will’s friend Mike snapped Will out of the vision.
Will had another vision the following evening. He went to have a toilet break in the middle of the night, and was returning to his bedroom. However, he saw a red light illuminating the walls of his house. The front door swung open, revealing the Upside Down beyond it, where the red storm violently raged once again. Will walked out into the Upside Down and witnessed the obscured but distinctive silhouette of the Mind Flayer amongst the clouds.
On Halloween night, Will experienced yet another vision while trick-o-treating in Loch Nora, a wealthy neighborhood in Hawkins. He found himself in the Upside Down version of the neighborhood. At first, Will heard a strange chittering sound coming from multiple directions. Then, he watched in horror as the Mind Flayer rose high into the air before pursuing him through Loch Nora. Will hid behind a wall, unaware that the Flayer was close behind him. However, Mike found Will and snapped him out of the vision before the Flayer could touch him.
Will’s next vision took place at school, shortly after he encountered Dart in the bathroom. Will found himself in the Upside Down once more, standing in the school corridor. Suddenly, the Flayer’s dark mist began to flood into the corridor before chasing after Will. After running outside and onto the field, Will stopped and turned to see the Flayer looming high above the school. Remembering what Bob had told him as they drove to school, Will attempted to confront the Flayer, yelling at him to “go away!” The Flayer ignored Will, continuing to pursue him before entrapping him within one of his many coils of mist. From this point on, the Flayer began to slowly take over Will’s mind and body.
The huge silhouette of the Flayer appeared behind the Gate as Eleven attempted to close it. The Flayer attempted to stop El, sending one of his coils through the Gate to attack her; however, El successfully disintegrated much of the coil. She then finished the job of closing the Gate, sealing the Flayer back inside the Upside Down.
Sometime later, during the Hawkins Middle School Snow Ball, the Mind Flayer loomed over the Upside Down version of the school, having survived the assault on the Gate.
The Mind Flayer is gargantuan and spider-like, being at least 50 stories tall. The precise details of his anatomy remain unknown, due to the thick, black cloud-like substance which envelops him. It is unclear whether he is entirely composed of this substance, or if his body contains any solid elements.
However, the creature does appear to have multiple limbs, some of which branch into several appendages; these limbs visually resemble the tendrils and vines present in the Upside Down. He seems to have an elongated, almost match flame shaped head which sprouts from the central body. His presence is often accompanied by dramatic red lightning, which is mentioned frequently by Will as “The Storm”.
Pockets of the black mist could move independently while remaining under the control of the Mind Flayer. One of these pockets left the main body and latched itself onto Will Byers, allowing the Mind Flayer to possess him. Will’s friends and family eventually forced the creature to abandon Will, with the mist flying away into the sky.
The Mind Flayer telepathically commands his army, consisting of Demodogs and the tendrils, to kill and destroy humans (except for its host Will). He also displays a sense of human level intelligence, as he forced Will to lie in order to kill numerous soldiers.
Hive Mind: The Mind Flayer’s most distinctive feature is the ability to take control and command of the creatures from the Upside Down and later Will. Upon having its feeding area burned, he sent multiple Demodogs to the tunnels in order to deal with the problem. He also had them try and stop Eleven from closing the gate. The downside of this mental connection was that the burning of tendrils would affect the Demodogs and Will, and most likely the Flayer itself. Will was also able to learn instinctive knowledge of its goals, the tunnels and weakness. Despite the hive mind’s reach, when Eleven sealed the rift between worlds, the connection was severed and led to the death of its subjugates.
Possession: By imbuing a portion of his essence on an affected subject (despite both the Flayer and Will being in separate worlds), the Mind Flayer is able to link the infected to the rest of his army. An example of his power was how he tricked Will into sending numerous soldiers to their death by having Will tell them his weakness was within the feeding area in the tunnels. The possession can be severed by subjecting the infected to extreme heat, which burns the essence out of its body by making it uninhabitable due to a weakness to heat and light.
Umbrakinesis: The creature could manipulate his own shadow/mist body to forcibly possess and attack. He was able to possess Will through an episode he was suffering, despite his physical body remaining in the Upside Down. Through the gate, he also attempted to attack Eleven as she closed the gate, but her great power was able to block his attempt.
