Both! Sort of. Wanda (Elizabeth Olsen) and Vision (Paul Bettany) were always emotionally connected because they were both entangled with an Infinity Stone called the Mind Stone. Wanda was exposed to it when she was being experimented upon by HYDRA, and Vision had it living literally inside his head.
Vision is also made sentient with the Mind Stone, which is taken out of Loki's scepter and placed into Vision's head by Ultron. Additionally, Age of Ultron's climactic battle between the megalomaniacal robot and the Avengers allows Vision and Wanda to spark their bond.
Wanda and Vision's relationship is one of the linchpins around which the plot of Avengers: Infinity War turns, yet their initial courtship happened entirely offscreen, leaving fans to wonder how the two came to care about one another so deeply that it made risking half of humanity not just okay, but necessary.
Does Wanda fall in love with Vision in the comics?
When Scarlet Witch first joined the Avengers, she had a bit of a crush on Captain America. That didn't last, as she met and fell deeply in love with The Vision. Many years later, they would revisit their attraction.
Doctor Strange 2's main villain turned out to be Wanda Maximoff, who went full evil in her quest to reunite with her children after losing them in WandaVision. She has been tapping into chaos magic using the Darkhold.
Wanda unknowingly uses Mephisto's disassembled soul to magically become pregnant (what with Vision being an android and all) and when Mephisto's soul is reassembled, she loses her twins — hence how the “House of M” storyline comes into being.
Because her powers are the same energy as the Mind Stone. As seen in Age of Ultron, Wanda and Pietro were given their powers by von Strucker, using Loki's Scepter (which contained the Mind Stone). Because of this, Wanda is the only person who could destroy the stone.
Once Hank Pym restored Vision's data he became more subdued, but his differences were so great that Scarlet Witch had difficulty interacting with her now-reconfigured husband. The friction between them grew, slowly collapsing their relationship over time.
What is WandaVision's story? WandaVision's basic setup finds Wanda and Vision living in a sitcom-style suburban world as a married couple with two children. Each episode (at least those featured in the various trailers) is modeled after sitcoms from different eras (I Love Lucy and I Dream Of Jeannie among them).
In the comics, Wanda and Vision get pregnant through magic — since Vision is a robot, that's seemingly their only option. They have twins named Thomas and William. However, it's eventually revealed that Tommy and Billy were actually created using fragments of the soul of a demon lord named Mephisto.
Based on the tactic of narrowing down Wanda's age, Wanda would have remained in the 18-20 range throughout Avengers: Infinity War and Avengers: Endgame. Scarlet Witch was a vital figure in the former, which took place in 2018. In the end, she fell victim to Thanos' Snap.
Wanda's gone full villain, harming anyone and everyone that gets in her way so she can find her boys. She kills, maims, outsmarts, and enchants whatever she has to in order to reach her goal, but that goal doesn't entirely make sense and results in forcing Wanda to learn a lesson she already did in WandaVision.
Martian Manhunter's powers make him one of the Justice League's most potent members. It's that mix of abilities that will help Martian Manhunter beat Scarlet Witch. Not only is he a physical powerhouse on par with Superman, but his shapeshifting, invisibility, intangibility, and telepathy make him even more versatile.
As her powers likely come at least in part from the Mind Stone inside of Loki's scepter, Wanda's abilities include telekinesis, energy manipulation, and some form of neuroelectric interfacing that allows her to both read thoughts and also give her targets waking nightmares.
If you pay close attention to Wanda, you'll notice the tips of her fingers are now stained black. In "Wandavision," she faces off against a witch named Agatha Harkness, whose hands also become stained after trying to absorb Wanda's chaos magic.
The third installment of WandaVision is titled "In Color," it finds Wanda and Vision living in a '70s-style sitcom as they deal with Scarlet Witch's surprise pregnancy. Of course, this isn't a normal pregnancy, as Wanda goes through an entire nine-month pregnancy cycle in the span of just one day.
They named Tommy after Dr. Phineas Thomas Horton, the scientist who created Vision's android body back in World War II. They named their other son William after Simon Williams, the Avenger whose brain patterns were used to bring Vision to life.
In the comics, Doctor Strange's third eye is an organic manifestation of the Eye of Agamotto. It represents the wisdom of the sorcerer Agamotto and his fellow Vishanti, allowing Strange to see his enemies' true intentions and break magical illusions.
Both are extremely powerful, but in Doctor Strange and the Multiverse of Madness, Wanda demonstrates the extent of her powers like never before. So in terms of raw force, she is definitely the more powerful of the two. Stephen, however, benefits from years of training as the Sorcerer Supreme.
