Summary
White Vision's return in the MCU could help avoid the problematic revival of Iron Man and preserve Tony Stark's heroic death in Avengers: Endgame.
The fact that White Vision is an A.I. derived from Tony Stark's J.A.R.V.I.S. makes him an ideal mentor and a direct substitute for Iron Man in the upcoming Disney+ series, Ironheart.
Bringing back Iron Man, even in the form of an A.I., would diminish the impactful and monumental departure of Tony Stark, which was brilliantly depicted in Endgame. It is preferable to maintain Iron Man's legacy as that of a selfless genius who used technology to save the entire universe.
Iron Man's return in the MCU presents potential issues, but the introduction of White Vision offers a viable solution for the franchise. Robert Downey Jr.'s portrayal of Tony Stark, aka Iron Man, played a crucial role in propelling the Marvel Cinematic Universe to immense popularity, culminating in his heroic demise in Avengers: Endgame. J.A.R.V.I.S., Tony's AI assistant, underwent a significant transformation and became Vision after being integrated into a robotic body in Avengers: Age of Ultron.
Unfortunately, Vision met his demise at the hands of Thanos in Avengers: Infinity War, but was subsequently revived as both Hex Vision and White Vision in the Disney+ series WandaVision. At the conclusion of WandaVision, White Vision regains his memories and separates from Westview and Scarlet Witch, leaving his future role in the MCU uncertain. Nonetheless, the most suitable avenue for Vision's return would be in the upcoming Disney+ series Ironheart, particularly as it would serve as a way for the MCU to resist the urge to bring back Tony Stark.
Why The Ironheart Show Is White Vision's Best Return
Riri Williams, portrayed by Dominique Thorne, will make her first appearance in the Marvel Cinematic Universe (MCU) in the upcoming film Black Panther: Wakanda Forever, releasing in 2022. In this movie, Riri creates her own rendition of Tony Stark's Iron Man suit and transforms into the superhero known as Ironheart. The MCU modifies Riri's background from the original comic book, presenting her as an MIT student who constructs her suit following Tony's passing. In the comics, Riri is depicted as Tony's apprentice, with an AI version of Tony guiding her through her origin story.
Since Tony Stark is deceased, White Vision could join the cast of Ironheart as a mentor figure for Riri. White Vision, originally created as Tony's AI named J.A.R.V.I.S., is an ideal candidate to become a surrogate Iron Man and serve as Riri's trusted companion. Introducing White Vision into Ironheart would also allow the MCU to maintain the significance of Tony Stark's demise in Avengers: Endgame.
Why The MCU Needs To Avoid Reviving Iron Man
In the climactic battle of Endgame, Tony Stark delivers one of the most memorable farewells in cinematic history. With the six Infinity Stones in his possession, Tony faces off against Thanos, declaring, "And I....Am....Iron Man" as he eradicates Thanos and his army. This act of heroism ultimately costs Tony his life, creating a powerful and irrevocable exit for the Marvel Cinematic Universe (MCU). Even though Riri's MCU origin is overshadowed by Tony's absence, the magnitude of Tony's sacrifice is too significant to be undone.
Even if Robert Downey Jr. were to return as the voice of Tony in an A.I. form, it would compromise the masterful ending that was created. The reception of the post-Endgame movies and shows in the MCU has been mixed, unlike the overwhelmingly positive reception of the first three phases. This could tempt the franchise to revive Tony Stark, as his presence would undoubtedly bring back his signature wit and humor. However, it is best for Iron Man's legacy to remain that of a brilliant technological genius who selflessly saved the universe.
