"Vecna seems to be actually intrigued by Nancy being able to figure him out, to be able to get this close to the truth... I think this is more Vecna's narcissistic traits that pull him to Nancy, why he wants to give her this information."
She narrowly evaded death each time, but it could eventually catch up to her. By targeting Nancy, Vecna would demonstrate that he's more frightening, intelligent and powerful than anyone initially assumed. She's easily the character who knows the most about him and understands fragments of how his mind works.
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).
In that campaign, the monster they face is the Thessalhydra, and there are several good reasons to believe that this is the creature that Nancy sees in her Vecna vision.
Vecna Will Target Nancy In Stranger Things Season 5 - But Will Do More Than Kill Her. Vecna will continue to terrorize Hawkins in Stranger Things season 5, and Nancy might be his next target, but he will do more than kill her.
Instead of escaping Vecna's Mind Lair by hearing her favorite song, Nancy is actually released by Vecna himself. Her freedom comes with a price: He gives her a vision of his plans for Hawkins and tells her to pass that message on to Eleven (Millie Bobby Brown).
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.
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.
Inside Vecna's realm, he preyed on Nancy's guilt over Barb's death. But Nancy didn't only see horrifying images from her past — she also saw glimpses of Vecna's past, which is how she learned he's Henry Creel.
She Doesn't Have a Great Aim
After the Hawkins team develops a plan to defeat Vecna, Nancy is in charge to blow his head up with a shotgun. However, either she didn't have a great aim or she was trying to play it safe because she didn't hit him in the face even once, and that may be the reason why Vecna is still alive.
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.
What was Chrissy's Trauma? Chrissy's life appears to be free from flaws on the surface, but in reality, she is struggling terribly to conceal her depression and self-image stemming. She was struggling with these issues, which resulted in her developing an eating disorder due to her mother's verbally abusive comments.
Vecna's obsession with time appears to be linked to his hatred of humanity. He views time as a human imposition on the natural world; an attempt to impose order on nature.
However, within the red smoke of Vecna's Mind Lair, it wasn't the song itself that saved her, but the memories it conjured up. What broke through to Max was the happy, loving memories of her friends, particularly Lucas and Eleven, and these were what truly allowed her to break free of Vecna's grasp and escape.
Wheeler is Vecna's sister are pretty slim. While it's possible on a theoretical level, it would just be a really weird plot twist, even for Stranger Things. However, it's still odd that Mrs. Wheeler was the only side character with a poster.
The theory predicts that Vecna wants to regain his human form, and he will use Will to do so in Season 5. Knowing that Vecna singled out Will in Season 1, it's a reasonable theory, but it might go too far. After all, Vecna already has a human form, and he has vowed to eliminate humanity.
As Sink put it: “You kind of learn in the season that he targets people that are in a real [bad] place, and Max is obviously one of those people. Just with everything with Billy, so she was kind of like the perfect target.
One explanation for why time in the Upside Down is frozen, rather than flowing ahead to 1986 like in the real world, could be the impact of Eleven opening that first gate. The outburst of power she used and the deep emotions that were running through her were enough to shock the Upside Down into time standing still.
All those years ago, he felt a connection to Eleven because of their shared abilities and the pain that they had both endured at the hands of Dr. Brenner.
We know Eleven was born in 1971, which means her mom got pregnant with her during the tests, sometime in 1970. A 1959 flashback in the mid-season 4 finale reveals a 12-year-old One (Jamie Campbell Bower). That puts One, a.k.a. Vecna, as 24 when Eleven was born.
2 Vecna's True Identity
As a child, Vecna was just Henry, a young boy with powers unlike anyone else. Henry had been the one to kill his mother and sister while his father was left in a facility. Henry's identity changed when he was taken away, and he became known as One, the first of many kids with psychic abilities.
Played by Jamie Campbell Bower, each prosthetic was glued to his skin with medical adhesive by prosthetics designer Barrie Gower and his team. For the finishing touch, Vecna was covered in "glossy slime to make him really, really glossy and wet looking," according to Gower.
His first victim was Chrissy Cunningham. Vecna targeted Chrissy by using her depression and eating disorder against her in his visions. Chrissy was killed in Eddie Munson's trailer, and the first gate was opened on the ceiling.
Joe Manganiello's character Arkhan fought against Vecna with the adventuring party Vox Machina in the web series Critical Role. He then stole the Hand of Vecna and replaced his own hand with the artifact.
