Bulletproof is a fictional character a comic book superhero from the Image Comics series Invincible. His first appearance was in Invincible #9. Before the name "Invincible" was settled on, "Bulletproof" was one of the proposed names of the main character of the series. Bulletproof's costume also appears to be based on early designs for Invincible's costume, and in Invincible's first visit to Art Rosenbaum, the tailor who supplies his costumes, Art's initial offering ends up being worn by Bulletproof.
