WandaVision introduced White Vision into the Marvel Cinematic Universe. In the finale, we see him take off and leave Westview. This was followed after the Hex Vision helped him tap into his memories. They were embedded deep in his codes. But the moment White Vision realized who he was, he was not a killing machine anymore. Even without the Mind Stone, White Vision gained some sense of consciousness.
This new incarnation of Paul Bettany’s MCU character is based on the colorless version of Vision that was a member of the Avengers and its west coast branch in the late 1980s and early 1990s in Marvel Comics. Following the dismantling of the original, red-yellow-and-green Vision, Hank Pym rebuilt him as the White Vision. He functioned purely on logic, which distanced him from the hero that Scarlet Witch and the Avengers had come to know.
WandaVision drew inspiration from the emotionless Vision and adapted him to the MCU in episode 8’s post-credits scene. It was revealed that S.W.O.R.D. was able to create him by reactivating Vision’s body with a touch of Scarlet Witch’s Chaos Magic. White Vision of course isn’t the real Vision, but he did have his memories restored before the end of the season finale.
the character is off on his own, possibly on a journey of self-discovery. His screen-time was limited and closure was never offered. This leaves the fans of WandaVision with some unanswered questions. One particular point of interest is the weapon in his head. It couldn’t have been the actual Mind Stone, since it was destroyed off-screen by Thanos after Avengers: Infinity War.
Whatever it was, it acted as an adequate replacement. Here’s why it could have been made from the Tesseract that was introduced in Captain America: The First Avenger. WandaVision didn’t say much about how S.W.O.R.D.’s scientists reconstructed White Vision. It was just revealed that they used residual Chaos Magic energy from the drone that Wanda shot down in a previous episode. They also didn’t explain his powers. Much of what the original Vision could do came from being powered by the Mind Stone. Though the White Vision didn’t have this same energy source, he still possessed these capabilities, including the ability to shoot energy beams from his head.
Like the hero that came before him, White Vision’s energy beams were directed from an object in his forehead that looked similar to the Mind Stone. Westview’s Vision was able to replicate the original’s Mind Stone abilities because he was a magical manifestation of Scarlet Witch’s power and the Mind Stone itself, but the same explanation can’t apply to White Vision. It’s still not clear what that weapon was in White Vision’s head, but it certainly wasn’t the real Mind Stone.
The object is unidentified. It contained an immense level of power. It’s important to keep in mind that White Vision was able to match up quite well with Westview’s version. That’s impressive, considering that the fake duplicate seems to be just as powerful as his predecessor. When their rays were locked, Vision gave it everything he had, but he couldn’t hold up against the force of his opponent’s blast. Though the two appeared to be on an equal playing field physically, it’s their Mind Stones that set them apart during their battle.
Project Cataract – the name given to the experiment geared toward bringing Vision back online – was an ambitious task for S.W.O.R.D., but there are examples in the MCU of government agencies having access to this level of advanced technology, with S.H.I.E.L.D. being a big example. S.H.I.E.L.D. had a gold mine on its hands when it acquired the Tesseract (Space Stone in disguise). SHIELD had it in its possession for several years before it was eventually stolen by Loki (Tom Hiddleston).
It could be that someone within S.W.O.R.D., like Josh Stamberg’s Tyler Hayward, could have gained the clearance necessary to work with the Tesseract prior to 2012. If so, S.W.O.R.D. could have engineered weapons of their own with the Tesseract. The MCU has yet to explain what kind of relationship S.W.O.R.D. had with S.H.I.E.L.D. in the past, but it does seem plausible that Maria Rambeau (Lashana Lynch) and Nick Fury (Samuel L. Jackson) may have been willing to work together on projects that would benefit both organizations.
Something that came from the Tesseract being added to his body would explain why White Vision’s “Mind Stone”, energy blast, and eyes were blue. It may be that the blue color was WandaVision’s way of teasing the Tesseract’s role in his creation. White Vision’s new stone being connected to the Tesseract would also make sense of why it’s so powerful. After all, the Tesseract really is the Space Stone. Both versions of Vision being powered by an Infinity Stone would explain why they’re able to fight with each other. Only a weapon that’s a product of another Infinity Stone should have been able to overpower the Mind Stone possessed by Westview’s Vision.
