18 Years Later, the MCU Just Killed Off One of Its Oldest Heroee

Not all heroes wear capes. Nor do all of them have arms and legs or even a physical form altogether. To be a hero in the Marvel Cinematic Universe , all it takes is a willingness to make a sacrifice for others, which is precisely what happened in the second episode of VisionQuest , when the show killed off what is effectively the longest-running hero in the MCU. After Vision (Paul Bettany) was shot with adamantium bullets in episode 2, he no longer has enough power to house all seven AI entities living within his programming.
