It produces material featuring numerous well-known superhero characters, including Superman, Batman, Wonder Woman, Green Lantern, The Flash, Aquaman, and Green Arrow. Most of this material takes place in a shared fictional universe, which also features teams such as the Justice League, the Suicide Squad, and the Teen Titans and well-known villains such as the Joker, Lex Luthor, Harley Quinn, Darkseid, and Catwoman. The company has also published non-DC Universe-related material, including V for Vendetta, and many titles under their alternative imprint Vertigo.
