Quick Answer: Vision is weak in Avengers: Infinity War because he is critically injured by Corvus Glaive's weapon during the opening attack in Edinburgh, which prevents him from phasing and makes him vulnerable. This occurs early in the film, specifically in the scene set in Scotland where Wanda Maximoff and Vision are ambushed. The injury damages the Mind Stone embedded in his forehead, which is essential to his powers and life force, forcing the Avengers to seek help from Shuri in Wakanda to attempt a safe removal.

Key Facts

Vision is attacked by Corvus Glaive in Edinburgh, Scotland, early in Infinity War
Corvus Glaive's weapon prevents Vision from phasing, a key defensive ability
The Mind Stone in Vision's forehead is damaged, making him vulnerable and requiring medical attention
Shuri in Wakanda attempts to safely remove the Mind Stone but is interrupted by Thanos's forces
Vision dies twice in the film: first temporarily when Thanos removes the Stone, then permanently when Thanos uses the Time Stone to reverse Wanda's destruction of it

Overview

In Avengers: Infinity War (2018), Vision, the synthetic being created by Tony Stark and Bruce Banner using J.A.R.V.I.S., Ultron, and the Mind Stone, plays a pivotal but weakened role. Following the events of Avengers: Age of Ultron (2015) and Captain America: Civil War (2016), Vision and Wanda Maximoff are in a relationship and hiding in Edinburgh. The film opens with Thanos sending his Black Order to Earth to retrieve the Infinity Stones, targeting Vision because he hosts the Mind Stone. Historically, Vision has been one of the most powerful Avengers, with abilities including density manipulation, flight, energy projection, and interfacing with technology, all tied to the Mind Stone. His vulnerability in Infinity War marks a significant shift from his previous appearances, where he was instrumental in battles like the one in Sokovia.

How It Works

Vision's weakness stems from a direct attack by Corvus Glaive, a member of the Black Order, using a specialized weapon that disrupts his phasing ability. Phasing allows Vision to become intangible, avoiding physical harm, but Glaive's weapon interferes with this mechanism, rendering him solid and susceptible to injury. The weapon also damages the Mind Stone, which is the source of his consciousness and powers; this damage causes him pain and instability. In response, the Avengers take him to Wakanda, where Shuri attempts to separate the Stone from his body without killing him, using advanced vibranium-based technology. However, the process is slow and requires precise work, leaving Vision incapacitated and dependent on protection from other heroes during the Battle of Wakanda.

Why It Matters

Vision's weakness is crucial to the plot of Infinity War because it forces the Avengers into a defensive position, culminating in the Battle of Wakanda to protect him and the Mind Stone. His vulnerability highlights the stakes of Thanos's quest, as the loss of the Stone would mean Vision's death and give Thanos a key component for the Infinity Gauntlet. This drives emotional arcs, particularly for Wanda, who must ultimately destroy the Stone and Vision to prevent Thanos from acquiring it, only for Thanos to reverse this with the Time Stone. The scenario underscores themes of sacrifice and the limits of power, impacting the broader Marvel Cinematic Universe by leading to the Blip and setting up Avengers: Endgame.
