However, it looks like Marvel Studios is going to tweak his backstory in the upcoming Captain Marvel. In the latest Captain Marvel trailer, Nick Fury can be seen with some small bandages above his eye, which means that he was attacked by someone, or something.
Nick Fury may lose his eye in a much different way in Captain Marvel than he did in the comics.
Marvel Studios has been on a roll with their promotional material this week, but Captain Marvel may finally show us the real reason that Nick Fury wears an eye patch in the Marvel Cinematic Universe.
In the Captain Marvel comics, he is an alien Flerken, which is a pretty crazy creature that has massive tentacles underneath its cute cat exterior.
