And that's why I think having Vecna as a representation of [PTSD and] depression can be really helpful for those who do struggle with [these issues] as a way of externalizing [and depersonalizing] them.”
The latest series of Stranger Things is another brilliant blend of horror, sci-fi fantasy and drama. But new villain Vecna is a reflection of something very real: post-traumatic stress disorder, depression and grief.
Vecna's power not only takes a mental toll but also a physical one. Much like depression, Vecna's victims experience physical symptoms such as exhaustion, lack of sleep, headaches, and nosebleeds. Similarly, when dealing with depression and trauma, a person's physical health worsens.
Brenner (Matthew Modine) states in the Stranger Things episode "Papa" that Vecna "consumes" everything about his victims, Vecna targets traumatized victims because it builds for him a well of sad and angry memories to draw from. With each victim, he can become gradually more powerful.
While there are no direct statements, it's still clear that Max suffers from mental illnesses, such as depression, trauma, and even PTSD.
Vecna's powers allow him to form psychic connections with people in reality, especially teenagers dealing with trauma and mental health issues. Vecna develops these connections with young and vulnerable teens so that he can get out of the Upside Down and gain access to the real world by opening four gates or portals.
In the visions of her trauma induced by Vecna, Chrissy's mother appeared both mentally and emotionally abusive towards her daughter - and it's implied her comments about Chrissy's figure caused her daughter to develop her eating disorder.
While falling into the dark dimension, One/Henry is struck by lightning, disfiguring him.
In the game, Vecna seeks power through artefacts, while in the series, he enhances his powers by consuming the essence of his victims, like the other gifted children in the lab, and absorbing their powers. When he took over the Mind Flayer, he gained control over the Demogorgons and other monsters.
Clocks represent a passing of time, which can represent the fact that Vecna's victims' time has nearly run out — it is no coincidence that many of the clocks are set to midnight. Throughout the series, we learn that Vecna is a human who found himself trapped in the Upside Down for years thanks to our girl, Eleven.
Once he takes control of the mind, he traumatizes them by showing the visions of their dark past. He takes them to unknown places and gives them a glimpse of himself. The pain of his victims doesn't end here. Every single one of his victims experiences nose bleeding and severe headaches as well.
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.
Obviously still a sociopath, but now influenced by The Mind Flayer as well, Vecna started killing teenagers, imprisoning their bodies in the Upside Down version of his family home. The key to defeating Vecna most likely lies in his origins, so it's great that the Hawkins teenagers were able to figure it out.
Vecna is choosing victims based on their own subjective guilt, not their actions. : r/StrangerThings.
"Vecna really is a creature that has mutated in the last however many couple of decades during his time in the Upside Down," prosthetics designer Barrie Gower said. "This is where he has become more overtaken by the Upside Down world and become pretty much possessed and mutated."
"The reason why Vecna only has a single eye and hand is due to a betrayal by Kas", who used the sword against his former master. "In the third edition of Dungeons & Dragons, the Sword of Kas is a +6 unholy keen vorpal longsword that grants a +10 modifier to the Strength score of its wielder".
Hawkins has suffered a lot of trauma over the years - not all of which is connected to Hawkins Lab and the Upside Down - and Vecna's curse takes advantage of that. Vecna appears to carefully choose people who feel a strong sense of guilt or shame, particularly if those emotions are repressed.
Vecna feeds off his victims' trauma and haunts them with their own darkest thoughts.
And while his usual modus operandi is to embody his victims' negative self-talk (another very real psychological phenomenon), this time he is telling Nancy his plans and then releasing her so she can report back to everybody—Eleven included—that the end is nigh, with the goal of discouraging and disempowering them.
The Hand and Eye of Vecna were all that remained of the arch-lich Vecna after his betrayal at the hands of his trusted vampire lieutanant, Kas the Bloody-Handed. Using a sword crafted by Vecna himself, Kas manage to cut off Vecna's left hand and left eye before in turn being destroyed.
His method of killing is ritualized. Vecna started twisting bodies and removing eyes before imprisonment in the UD to fuel its own individual power. It takes the eyes to help hold the souls in darkness and because it did not wish to be observed.
Following Eleven's resistance, Vecna sought after Eleven's 'power', which he identified as "a means to open [his] own doors" (gates).
Though Fred appeared to be bright and level-headed, he harbored extreme guilt for his role in the fatal 1985 car accident, and believed many people look at him as a "murderer." This guilt and mental unrest made him a target of Vecna.
Eleven is examined as a child hero of the series who has a potential diagnosis of Post Traumatic Stress Disorder (PTSD), has significant psychosocial developmental delays that she continues to overcome as the series develops, and is an emblem for the cultural mythology of the 1980s.
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.
