This is a new video from WhatCulture that lists 10 Marvel Cinematic Universe characters who are AWOL. The MCU has an ever expanding list of superheroes, sidekicks, and villains. Unfortunately, not all of these characters have continued to be seen since their initial or last appearance. There may have been plans for them, but for various reasons where scrapped. Will we see any of them in the future? It seems highly unlikely. Check out the video below to see who made the list.
