50 free Justice League trivia questions with answers — entertainment quiz, new questions added Aug 2026.
The Justice League began in 1960 as a sales gimmick: Gardner Fox revived the Justice Society, Julius Schwartz renamed it after baseball's National League, and the seven biggest heroes in the DC catalogue fought a giant starfish. Marvel noticed and built the Avengers. Six decades later the League has been a UN-backed comedy troupe, a pantheon on the Moon, a magic team and a Saturday-morning cartoon with a talking dog. These 50 questions cover the comics and the screen: The Brave and the Bold #28, Starro and the film that inspired him, Snapper Carr, the Happy Harbor cave and the satellite, the Justice Society crossover, Justice League Detroit, Giffen and DeMatteis's JLI, Batman's one punch, Maxwell Lord, Grant Morrison's JLA and the Hyperclan, Identity Crisis, Justice League Dark, the Absolute Universe's villainous League, Super Friends and the Cincinnati train station behind the Hall of Justice, the Legion of Doom's swamp base, the 2001 cartoon's cast, Project Cadmus and the Bat-embargo. Easy questions stick to the founders and the famous bases; the expert tier asks about Warning from Space, Green Flame and Ice Maiden and Justice League of America #78. Every answer is cited to a page we checked, with a short explanation so you learn something even when you miss.
