Justice is a fictional character appearing in American comic books published by Marvel Comics. The character appeared in the New Universe imprint of Marvel Comics, primarily as the protagonist of a 32-issue comic book series of the same name published from 1986 to 1989. Most of its run was written by Peter David and penciled by Lee Weeks, though it also featured rare 1980s Marvel work from Keith Giffen. David later reintroduced Justice as a supporting character in Spider-Man 2099, a series with a very different setting. This version of the character, also known as the Net Prophet, was older and had different powers.
