Many sad tributes are being sent to the Marvel artist who worked on the X-Men, who died at the age of 52.

John Cassaday, a famous Marvel comic artist for his work on Astonishing X-Men, died on Monday. He was 52 years old.

A lot of sad tributes have been written for the artist, who was remembered as a visionary artist.

Robin Cassaday was the first person to tell people that her brother had died.

“My little brother John died at 6:51 p.m. in Texas.” His sister told everyone, “Please pray for me and my mom.”

The cause of death has not been made public, but Robin said Cassaday had been in the intensive care unit (ICU) for six days before he died.

Robin said at the time that he was stable but worried about his brain.

“All of his organs and heart are working normally.” “The most important thing is his brain,” Robin wrote as she asked for prayers.

In 1997, Cassaday got his start in the comic book business by working for Dark Horse and Homage Comics. He later went on to work for Marvel and DC.

Cassaday worked on stories for the X-Men, Superman/Batman, and Captain America while in charge of two of the biggest comic book brands.

But the man from Texas was best known for making the DC comic Planetary with Warren Ellis.

Before it ended in 2009, the comic had 27 issues that were well received.

In the same year, Cassaday directed his first TV shows, the miniseries Astonishing X-Men and the TV show Dollhouse.

Some of the brands he worked for were Levi’s and Ringling Bros. & Barnum Bailey Circus.

He worked on bringing back Marvel’s Star Wars comics and was the Chief Creative Officer for Humanoids before he died.

TRIBUTES THAT EMBRACE

As soon as friends and fans heard the news, they paid tribute to the artist.

Cassaday was “one of the most gifted and sought-after comic illustrators of his generation,” Mark Waid wrote in a touching Facebook post.

“I refuse to take any real credit for ‘discovering’ John Cassaday,” Waid wrote. “I also can’t take credit for having eyes that work.”

“But after that, we were friends for life, and it was amazing to see how quickly he became one of the best and most sought-after comic book artists of his time.”

“John Cassaday, I will say without hesitation and with very little fear of disagreement, was one of the very best illustrators and storytellers to ever work in the comics medium.”

“We are still processing the death of our friend John Cassaday. He was one of the best comic artists of all time and one of the nicest people you could ever meet.” There isn’t much else like his body of work, but he lives on in our memories and on our shelves, wrote comic artist Mark Millar.

“John Cassaday’s work has left an indelible mark on me and on the whole industry.” Comic book writer Scott Snyder wrote, “This is a huge loss for the comics community.”

Somebody else said Cassaday was a “artist of limitless talent.”

“John Cassaday, your planetary comic was one of the most important things I saw in real life. Also, your Captain America. And your wonderful X-Men. “And…damn, what a huge loss,” one fan wrote.
