A mysterious universe is discovered to be connected to our world. It appears to be a distinct realm from the Upside Down but is still crawling with its terrifying creatures. This hidden realm, known by fans as Dimension X, is darker, wilder, and far older than anything we’ve seen before.

Its connection to Hawkins is still a mystery, but it might hold the key to understanding everything that is happening in the town.

Inside the Strange Landscape of Dimension X

Season 4 of Stranger Things introduced Dimension X. Unlike the decaying mirror of Hawkins we see in the Upside Down, Dimension X is an alien world. It contains unexplored areas, a hidden land where darkness covered twisted roots, rocks floating under a dying light, strange flying creatures, and humanoid individuals inhabited the mysterious landscape.

The Upside Down became Vecna’s base, though it wasn’t his original stop. He was banished to Dimension X first, not in the Upside Down. This detail is vital because it changes the impression from just a “parallel world” to something untold.

The role of Dimension X in the attack on Hawkins is still unspecified. It harbors deadly species, including Vecna, the Mind Flayer, Demogorgon, Demobats, and overgrowing vines.

The Hellscape: Gateway Between Worlds

Since Volume 2 was released, many fans have been puzzled about the strange places in the series. This breakdown will explain what each place is and how they are linked.

We first got a glimpse of the Hellspace during Eleven’s battle with Vecna in 1979. The Hellscape is a dark passage that separates worlds, which comes before we enter the Upside Down.

Hellscape is the interdimensional barrier that separates our world and Dimension X. The Hellscape was initially indicated with red storms and no mountains. A deleted scene from Season 4, Episode 9, speculates on how Henry Creel falls into a glowing tear and how he leaves the Hellscape that led him to Dimension X.

Vecna’s Rise in Dimension X

Stranger Things: The First Shadow revealed that Henry Creel was born in 1947. He was taken to Dimension X, where he spent 12 hours. During his stay, he gained exceptional powers and returned with the Mind Flayer.

In 1959, when he arrived in Hawkins, he felt like an outsider and isolated himself, which made him different from others. This happened due to a view of a cruel and unforgiving world in his mind.

Later in 1979, Eleven banished him to Hellscape and he got sucked into Dimension X. The place broke him, his body was burned, and it twinkled badly after that. The strange world gradually reshaped him into Vecna.

Vecna created the Mind Flayer by using black energy from Dimension X. He shaped it to control minds, spread panic, and transform the dark energy of that strange place, which will turn him into a dark force controlled by his rage.

Vecna was the mastermind from the start who kidnapped Will Byers and possessed Billy. Right from the beginning, it’s obvious that Vecna thrived on pain and used people’s trauma. He was in charge the entire time, from the initial Demogorgon attack to when the first gate opened in Hawkins.

Ranking the Creatures of Dimension X

1. Vecna

Vecna aka Henry Creel, murdered his family as a child by using his mind powers. When Dr. Brenner at Hawkins lab experimented on him and named him One, he was the earliest child with powers before Eleven.

When Eleven discovered who he was during the fight in the lab, she overcame him and pushed him into Dimension X. It changed him into a noseless and twisted entity, covered in raw, wounded skin and massive, twisting tentacles.

2. The Mind Flayer

In Season 2 and 3, the Mind Flayer emerges as the main threat. It is a gigantic, shadowy figure made from twisting dark particles, which is regularly shaped into a huge spider. The Mind Flayer harms its victims by physically controlling living creatures, Demogorgons, Demodogs and manipulating human minds to rule them.

In Season 2, Will Byers was its main target as it filled his mind with dark visions and pain to keep an eye on Hawkins. Later in Season 3, the Mind Flayer possesses hundreds of rats and its victims to create an evil spider monster made of flesh and blood that follows its orders.

The Mind Flayer commands other monsters to assist in Vecna’s plan to destroy humanity and rule the real world through the Upside Down.

3. The Spider Monster

In Season 3, Spider Monster appears as a huge and creepy-like insect with long legs that enable it to move fast and climb up walls and ceilings. It has the power to hunt and infect its victim with deadly speed and wild intensity.

After the Gate is closed in Season 2, the Mind Flayer loses its psychic connection to the human world. It created a wild figure in Hawkins using rats and the bodies of its victims. In Season 3, the evil Spider Monster serves as the physical form of the Mind Flayer’s will. The giant and terrifying Spider Monster aims to kill Eleven and his friends, eliminating anyone who tries to stand against the Mind Flayer. Unlike Vecna, the evil Spider monster fights with crushing power, which makes it one of the deadliest threats to Hawkins.

4. The Demogorgon

The Demogorgon emerges in Season 1 in Hawkins as the initial creature from the Upside Down, which changes the story of the series. Looking at its appearance, this humanoid monster is tall with a huge, frightening mouth that opens as a “petal spreads”. It also has extraordinary abilities like telekinesis, enhanced strength, and rapid healing.

Eleven (Millie Bobby Brown) has the privilege to overcome monsters by using her telekinesis powers. She is the reason for their arrival in Season 4, where Russians train them to become deadlier and even more brutal.

5, Demodogs

Demodogs emerge as the youngest type of Demogorgon when Dustin Henderson (Gaten Matarazzo) finds a lizard and calls it “Dart,” unaware that it will grow to dog size.

The Demodogs are not as effective as Demogorgoans, but still alarming. They are a threat when they are in a group (controlled by the Mind Flayer’s mind). Among all of them, only one Demodog refuses to harm Dustin in the tunnels because it recalls its friendship bond and does not follow Mind Flayer’s order.

6. Demobats

Each Season of Stranger Things brings a new kind of demo monster. In Season 4, we meet the Demobats, flying beasts. These small bat-like creatures are complex to defeat when they strike in enormous numbers from all directions at the same time.

Demobats serve as Vecna’s eyes and ears, shielding the Creel House in the Upside Down. They terrifyingly bite their victims and wrap their tails around them to choke them. The season 4 finale showed Eddie Munson getting killed by the Demobats, which was one of the saddest scenes in the series.

7. The Vines

The scaring vines grow underground in Hawkins, inside the Upside Down, and connect the real world to the deadly Dimension. They seem like enormously tough tentacles; they wrap around their victims or anyone they hold.

These vines are connected to evil minds (Mind Flayer and later to Vecna). In the upcoming Season, the vines could speedily expand into Hawkins as the Upside Down and real world start to merge. They shrank across buildings, all over the streets, and people in a shocking way, which allows Vecna to watch everything closely.

What Dimension X Means for Season 5

With the Dimension X introduction, the story of Stranger Things has become more curious. It showed an ancient world separate from Hawkins and its typical risks. Dimension X is a clue that many dark worlds are hidden in the Stranger Things realm.

Dimension X will strongly impact what happens in Season 5 because the final battle is happening there instead of the Upside Down. Will Byers, who disappeared in Season 1, could have a deep connection to this mysterious realm. This is the time when Vecna could return with remarkable power, negatively charged by Dimension X energy. The birthplace of Mind Flayer and the hidden secret mystery of Hellscape are linked with Dimension X.
