Stan Lee revolutionized comic books by delicately balancing superhuman powers with humanizing choices and giving young people everywhere heroes they could relate to.
Thanks to his illustrious stamp on the industry, his legacy will live on long after his passing. At the same time, it makes his death that much more devastating, particularly for those who were lucky enough to work closely with the Marvel legend.
Soon after the sad news was announced, Chris Evans took to Twitter to celebrate Lee's contribution to pop culture.
"For decades he provided both young and old with adventure, escape, comfort, confidence, inspiration, strength, friendship and joy. He exuded love and kindness and will leave an indelible mark on so, so, so many lives," he wrote, before signing off with Lee's signature, "Excelsior!!"
There will never be another Stan Lee. For decades he provided both young and old with adventure, escape, comfort, confidence, inspiration, strength, friendship and joy. He exuded love and kindness and will leave an indelible mark on so, so, so many lives. Excelsior!!— Chris Evans (@ChrisEvans) November 12, 2018
Giving credit where credit was due, Robert Downey Jr. — who helped turn Lee's comics into an epic film franchise starting with the MCU's first movie, Iron Man — simply stated, "I owe it all to you," alongside a photo of them together.
Marvel Studios president Kevin Feige wrote, "No one has had more of an impact on my career and everything we do at Marvel Studios than Stan Lee."
Of course, it's not just the superhero staples who are mourning this loss. Black Panther stars Letitia Wright and Winston Duke paid tribute to the Marvel boss, as well as Tom Holland.
"How many millions of us are indebted to this guy, none more so than me. The father of Marvel has made so many people so incredibly happy. What a life and what a thing to have achieved," the Spider-Man star wrote on Instagram.

Stan Lee and Dr. Seuss and Ray Bradbury. That's where it begins and ends with me. To those of us who have been so deeply affected by the humanity of his imagination, the understanding of reaching beyond our potential and the necessity of tapping into our immeasurable imaginations, we thank you and are forever indebted. Rest In Peace Dear Stan. You made our time here a better one. #ripstanlee @robliefeld
