Marvel Kills Off a Major MCU Character In the MCU
At the end of the first episode of Secret Invasion Nick, Talos, and Maria are tracking down 2 backpacks containing bombs ready to go off. While the trio does their best to stop the attack, it still goes off. While the bombs don't get Maria Hill, Kinglsey Ben-Adir's Gravik does. Taking the form of Nick Fury, he takes her by surprise, shooting her.
Even though the real Fury eventually makes it over to her side, it is too late for him to save her life. Sadly, the agent who oversaw the Avengers Initiative and whom viewers were introduced to for the first time in The Avengers has passed away.
