Who Created the Upside Down? In the "Stranger Things" timeline, the earliest we see the Upside Down is during Eleven's time in the Hawkins National Laboratory when an experiment guided by Dr. Brenner results in her accidentally opening the gateway between our world and the hellish dimension on the other side.
There's been debate as to whether or not this scene implies that Eleven created the Upside Down or merely opened the first gate to it. But according to Millie Bobby Brown, the Upside Down existed before El ever meddled with it.
Millie Bobby Brown spoke about this in an interview with Variety in 2022. When the actress was asked if the Duffer Brothers explained that Eleven creates the Upside Down when she interacts with 001, she said, "They did tell me. She does.
Vecna likely shaped the Upside Down, as he is a non-native. Basically, the Upside Down adapts to as many memories as it can get of the real world. We see that mindflayer and Vecna can already access the human mind, so, it can likely use these memories to better adapt the upside down to more human enviroments.
Background. The history of the Upside Down remains mysterious. Exactly how and why it came into existence is unclear. Dustin theorised the Upside Down had existed for thousands, if not millions of years.
In episode 7, Vecna is revealed to be Henry Creel (played as a youngster by Raphael Luce), the son of Victor Creel (Robert Englund) and his wife Virginia (Tyner Rushing) shown in the 1950s flashbacks.
The truth about the Mind Flayer
Using his powers, he was able to control it and use it to do his bidding. With this reveal you find out that 001 is the ultimate monster in all of this and that the events of Stranger Things Season 4 have opened up a new supersized portal between the dimensions.
He's been subjected to the toxic environment for around 20 years and has become a part of it. His silhouette incorporates sharp shapes so that, even as a slow-moving character, his toothy appendages and jagged edges make him too dangerous to touch.
In 4th edition, the Open Grave book shows the leader of the cult of Vecna is a lich named Mauthereign.
Next up, the viewers go on to theorise that One/Vecna is actually Eleven's dad. Yep, told you it was wild. The theory claims that Brenner wanted to create a child with stronger powers, so he waited until One was old enough to become a father.
Sharing more about Eleven's real father Andrew Rich could be a great way to wrap up the story.

The Demogorgon monster was created by Spectral Motion, a creature effects company from Los Angeles that has previously collaborated with Guillermo del Toro. They just had a little over two months to finish the creature, so there wasn't much room for error.
In season 4, Peter Ballard notes that Kali was no longer at the lab in 1979. Given Kali's powers, it seems pretty self-explanatory as to how she was able to escape the lab. She either made herself invisible or was able to escape after manipulating the minds and visions of the guards.
Vecna was the one who originally kidnapped Will in season 1.
Based on the flashback in “The Hellfire Club”, he killed an estimated 21 people: 13 lab subjects, two orderlies, two guards, Ten, Alec, Dr. Ellis, and Six. A flashback during “The Massacre at Hawkins Lab” later reveals that Vecna killed even more people in Hawkins Lab than we thought.
Vecna was trained in the art of sorcery by his mother Mazzel, who was eventually executed by the government of Fleeth for practicing witchcraft.
Mike, on the other side tries to give strength to Eleven, who is at risk as she is captured by Vecna. Eleven gathers her strength and overpowers Vecna, who's just about to kill Max.
Ultimately, it is revealed in Stranger Things season 4's finale that the reason why Vecna was killing Hawkins teenagers was to create a massive gate that merges the Right Side Up with the Upside Down - and he specifically needed four bodies to do so.
While intending to get his revenge on Eleven and Brenner, Vecna also goes after victims who have dealt with traumatizing experiences in the past (reminiscent of his childhood and his time at the Hawkins lab).
Realizing he had tremendous psychic power, he haunted his family with visions before ultimately killing most of them. His father was framed for the murders and locked away in a mental hospital as a disturbed serial killer. Henry then found himself in the care of Brenner, who decided he wanted more kids like the boy.
What Does Vecna Want? Vecna's goal is to open as many gates to the Upside Down as he can, in order to help the Mind Flayer.
Remember also that we have evidence that powers can be inherited -- El inherited her powers from Terri Ives, for example. So it stands to reason that Henry inherited his powers from one of his parents.
What does the Mind Flayer want? According to what Flayed Billy (Dacre Montgomery) reveals during his final showdown at the end of season 3, the Mind Flayer's current plan is to kill Eleven because she is its one true enemy and the only force who can destroy it.
