50 free Arrowverse trivia questions with answers — trivia quiz, new questions added Oct 2026.
The Arrowverse grew from a single series about a hooded archer into one of the largest shared universes ever built for television. Arrow led to The Flash, and soon Supergirl, Legends of Tomorrow, Batwoman and Black Lightning were trading heroes, villains and whole storylines, with yearly crossover events that brought every show together. This quiz covers the lot: Oliver Queen's long road from castaway to hero, Barry Allen and his friends in Central City, Kara Danvers and her allies, the time-travelling misfits of Legends, and the masked newcomers who joined later. Expect questions on characters and their secret identities, the actors who play them, the big bads of each season, famous guest stars and the events that tied it all together. It starts with questions most viewers will get and builds to a handful only the most devoted fans will know, so it works for a casual rewatch night or a serious fan showdown. Every answer comes with a short explanation.
