Raghu Seetharaman was sent to an orphanage at the age of 10 after his parents tragically died in a fire. Raghu found an old book of trivia and thus began his lifelong obsession with knowledge. In high school. Raghu played in teen trivia competitions across the United States, earning the nickname "Quiz Kid". The final competition in New York was interrupted by the villainous Spirit King, who took the children and judges hostage. Mr. Terrific, the 'Man of a Thousand Talents,' arrived on the scene, subdued the Spirit King, and freed his captives. Mr. Terrific stayed to declare the national teenage trivia winner, who was Raghu. Impressed by the boy, Mr. Terrific challenged Raghu to a friendly competition himself. The two geniuses played for over 12 hours before the judges finally called it a draw and Mr. Terrific declared Raghu to be "the smartest boy in the world." Raghu helped Mr. Terrific solve dozens of New York's so-called Impossible Crimes, eventually donning a mask and costume as Quiz Kid and officially becoming Mr Terrific's sidekick. But in 1946, Raghu disappeared in the middle of their most difficult case' Whatever happened to Betsy Ross and Molly Pitcher? It was never solved.

Declared the "smartest boy in the world" by Mr. Terrific himself, Raghu's intellect was unmatched by anyone, save perhaps his mentor, although he beat Mr. Terrific in chess regularly. Raghu had a photographic memory not only for text and imagery, but also for movement, meaning he could master any fighting style simply by watching someone use it. This made Quiz Kid an incredibly formidable hand-to-hand combatant. Raghu had multiple inventions, including an aircraft he dubbed the Fair Play Flier, in development when he vanished.
