Warning: SPOILERS for WandaVision Episode 8 – “Previously On”
WandaVision episode 8’s post-credits scene introduced the White Vision, which sets up a battle between the Visions (Paul Bettany) similar to two Captain Americas (Chris Evans) fighting in Avengers: Endgame. Vision is still racing back home to Wanda Maximoff (Elizabeth Olsen) from when he was last seen in episode 7, “Breaking the Fourth Wall,” and the synthezoid is unaware his wife has met WandaVision‘s villain, Agatha Harkness (Kathryn Hahn), who was posing as their next-door neighbor, Agnes.
WandaVision’s latest episode dropped some bombshells about what really happened to the Vision after Avengers: Infinity War. The remains of the synthezoid were acquired by S.W.O.R.D., which had taken Vision’s body in an attempt to reactivate the most powerful sentient weapon ever built. Wanda went to S.W.O.R.D. headquarters hoping to get Vision’s remains for a proper burial, but Director Tyler Hayward (Josh Stamberg) showed her how S.W.O.R.D. was dismantling him instead. Hayward later lied that Wanda attacked S.W.O.R.D HQ and stole Vision’s corpse; in truth, Wanda left peacefully but, in her grief, she magically created her TV fantasy world in Westview, New Jersey after she visited the plot of land where Vision planned to build a house for them.
Meanwhile, S.W.O.R.D. actually reassembled Vision but Hayward deceived Monica Rambeau (Teyonah Parris), Dr. Darcy Lewis (Kat Dennings), and FBI Agent Jimmy Woo (Randall Park) at WandaVision episode 5’s briefing. S.W.O.R.D.’s revamped Vision and turned him into a white, monochromatic version of the synthezoid. Hayward also realized that he needed Wanda’s magic, derived from the Mind Stone that originally gave Vision life, to reactive the synthezoid, and they had enough remnants of Wanda’s power from their drone she attacked to bring the Vision online. But now that there are two Visions in WandaVision – one belonging to S.W.O.R.D. and the other magically constructed by Wanda – they are likely to fight when Hayward sends White Vision into the Hex, an event that immediately calls to mind the two Captain Americas fighting in Avengers: Endgame.
Cap vs. Cap is the best-loved instance of an MCU hero fighting his doppelgänger, in part because of Steve Rogers’ infamous quip at the end of the fight. The older Cap from 2023 defeated his 2012 self; not only was he more experienced in battle but Rogers also knew that saying “Bucky is alive!” would distract the younger Cap long enough for his future self to use the Mind Stone in Loki’s Scepter to incapacitate him. It’s an eerily coincidental twist that the two Caps tussled over the Mind Stone since the two Visions are powered and given life by that same Infinity Stone.
While the Avengers’ time heists in Endgame saw Captain America, Iron Man (Robert Downey), and Hulk (Mark Ruffalo) run into the 2012 versions of themselves after the Battle of New York, another MCU hero wh0 literally faced herself in that film was Nebula (Karen Gillan). The blue cyborg shot and killed the 2014 version of herself who was impersonating her and planning to deliver the Avengers’ Infinity Gauntlet to Thanos (Josh Brolin).
However, Iron Man actually pioneered fighting his own doppelgänger in the MCU. In Iron Man 2, an inebriated Tony Stark (Robert Downey Jr.) fought James Rhodes (Don Cheadle), who stole one of Tony’s spare armored suits. In fact, since the armor Rhodey donned (which would soon be named War Machine) was grey monochrome, the Iron Man 2 brawl between the two Iron Men that demolished Tony’s Malibu cliffside home is the actual forerunner to the expected Vision vs. White Vision clash in WandaVision’s finale.
