The comic book legend from the Philippines had inked a tonne of comic books, including X-Men, Superman, Batman, Avengers, and many more.

Inker Gerry Alanguilan has passed away at only age 51. First guy to ink off scans for Marvel. Delicate with a brush and bold with spotting blacks. And there’s several animated gifs of him if you look up smirking guy. Let’s not let comic book inkers be invisible. pic.twitter.com/BwCHUEsFXY — ComicTropes (@CTropes) December 21, 2019

Gerry Alanguilan has passed, at 51. He advanced inking techniques by being the first person to ink off scans at Marvel. He advanced the game on spot blacks in color comics. He advanced the soul of comics with Elmer, proving that he could tilt your entire world with just chickens. pic.twitter.com/weOudP4LdT — Travis Hedge Coke writes Patricia Highsmash (@TravisHedgeCoke) December 20, 2019

Alanguilan's own comic, Elmer, which is about a world where chickens gain the same intelligence as humans, was nominated for the Will Eisner Comic Industry award.

According to Rappler, Alanguilan was also the founder and curator of a museum in San Pablo, Komikero Komiks, where he helped preserve the artwork of "great Filipino comics illustrators of our past".

Some of you might also recognise the man from his "Hey Baby" video.

He was a terrific sport about the whole thing as well, even uploading a tutorial on how to achieve the look.

According to Rappler, his wife Ilyn Alanguilan, announced the news on Facebook.

Tributes quickly poured in for the man, with Marvel Comics' editor-in-chief C.B Cebulski offering his condolences.

Saddened to learn of the passing of Gerry Alanguilan. Another wonderful person taken from us too soon. An amazingly talented writer and inker, mentor to younger artists, and advocate for global comics, the comics world and Filipino art community lost a friend and hero today. — C.B.

Alanguilan's cause of death has not been disclosed.

A tweet from his official account on Dec. 20, his final tweet, was about a terrible pain he was going through.
