Tributes are pouring in from across Hollywood and the comics industry following the passing of legendary creator Stan Lee earlier today. Disney Chairman and CEO Bob Iger, DC Comics and numerous fans across the globe have already reacted to Lee's passing. However, the comics legend affected the lives of so many over the course of his long, illustrious career. Although there's no way any single article could capture every reaction to Lee's passing, here are some highlights, many of which focus on Lee's warmth, wisdom and legacy.Starting with those involved with the Marvel Cinematic Universe, Robert Downey Jr., whose Iron Man film launched the MCU, shared a picture of the two together, writing, "I owe it all to you." Chris Evans, who plays Captain America, took to Twitter to say, "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!!"Meanwhile, the Russo Brothers -- who directed the upcoming Avengers 4 -- posted a behind-the-scenes image of Lee, thanking him for "filling our childhoods with such joy."

Tom Holland, who plays Spider-Man, also shared a particularly touching post to his Instagram. "How many millions of us are indebted to this guy, none more so than me," he wrote. "The father of Marvel has made so many people so incredibly happy. What a life and what a thing to have achieved. Rest in peace Stan"

Praise for Lee also came from outside those in the MCU. Lee's longtime friend Kevin Smith posted a long tribute on Instagram, thanking Lee for his transformative influence in making Smith "the man [he is] today." Likewise, Dwayne Johnson, also known as the Rock, posted a picture of himself clasping hands with the comics legend, revealing that Lee gave the actor "some very sage advice I'll forever take to heart."

Of course, the loss of Stan Lee was felt prominently in the comics community. Jim Lee, who worked on such titles as Alpha Flight and The Uncanny X-Men before later becoming DC's Entertainment Chief Creative Officer-Publisher, shared a touching post about how Stan Lee's work impacted him "growing up as an immigrant in a strange, new world."

Punisher co-creator Gerry Conway also paid tribute to Lee, calling him "a major inspiration in my work as a writer and an editor." Additionally, fellow comics legend Frank Miller posted to Twitter, writing "Devastated by my pal Stan's passing. He was a childhood inspiration, an instructor to me when I was just getting started and a genuinely sweet man. Will miss him terribly."

Comics writer Gail Simone shared her experiences with Lee over the course of several posts. In her first post, she noted that each of the three times that she'd met Lee, he'd told her "something literally life-changing," a common theme among those who met the legend. She also shared her last memory of Lee, in which he "almost accidentally ran [her] over with his Rascal scoot backstage at a con." Simone then wrote about how it was a happy memory, adding, "But he was so kind and funny about it. I’m glad our last meeting was laughter."

 Old Man Hawkeye and Old Man Quill writer Ethan Sacks shared a touching story about a message he received from Lee following the birth of his own daughter. "When my daughter was born, Stan Lee sent me this email message," Sacks wrote. "'I hereby proclaim Naomi Sacks an official superheroine, forevermore entitled to wear the colors and insignia of the fabled House of Sacks. So hath it been stated. So shall it be.'"

Tony Stark: Iron Man and Fantastic Four writer Dan Slott also offered his reaction to Lee's passing, explaining that "no writer or their work has ever had as profound an effect on [his] life as that of Stan 'The Man' Lee." Slott then posted a video of he and Lee embracing.

Lee, who was also famous for his cameos will next appear as an animated version of himself in Sony's Spider-Man: Into the Spider-Verse. The comics legend had already filmed his cameo in Avengers 4 at the time of his passing. Although Lee may have passed, his legacy will endure for generations to come. The final reaction to Lee's passing that we'll leave you with is the heartbreaking, entirely black image that former Marvel editor-in-chief Joe Quesada posted to his Twitter.
