The sudden passing of Chadwick Boseman, who most notably played the Black Panther within the MCU (among MANY other brilliant roles), left much of the world absolutely stunned.

Boseman, 43, had been quietly battling colon cancer since 2016, which means he was struggling with the disease throughout basically the entirety of his Marvel career. If that's not some true king s**t I don't know what is.

The outpouring of grief and heartfelt tributes to his life and legacy have been incredibly touching, including this official tribute video by Marvel featuring behind-the-scenes footage of him in action and glowing testimonials by his co-stars.
