Blade (Eric Brooks) is a fictional character appearing in American comic books published by Marvel Comics. Created by writer Marv Wolfman and penciller Gene Colan, his first appearance was in the comic book The Tomb of Dracula #10 (July 1973) as a supporting character, but later went on to star in his own storylines. Blade is usually depicted as a human-vampire hybrid, who aims to rid the world of evil vampires, and trained himself to become the ultimate vampire hunter.
The character has been substantially adapted from the comics into various forms of media, including films, television series, and video games. Blade was portrayed by actor Wesley Snipes in the films Blade, Blade II and Blade: Trinity, and by Sticky Fingaz in the television series Blade. Mahershala Ali is set to play the character in the Marvel Cinematic Universe.
