A nerdish bookworm, Flynn is brilliant beyond compare. By the time he was 31 years old Flynn had obtained 22 academic degrees (12 Bachelors, 6 Masters, and 4 Ph.D.s), including four in Egyptology, a Ph.D. (or two) in Comparative Religions, and a Ph.D. in Cryptology. In the beginning of the Quest for the Spear his Egyptology professor signs off on his 23rd degree, however it is unknown if this is a masters or bachelors.
Practically addicted to learning, Flynn would have continued being a perpetual student had one of his professors not kicked him out of college, insisting that he get some real-world experience. Upon receiving an invitation, Flynn applied for a job as a librarian in New York. Unexpectedly, he was successful in his job interview and was recruited into an ancient clandestine order of Librarians who have protected a range of historical and often magical items (such as the Ark of the Covenant) for centuries.
Flynn is, effectively, a polymath, highly intelligent and resourceful. His years of study have made his powers of observation and deductive skills comparable with those of Sherlock Holmes. His ordinary skills (which did not qualify him for the job) include knowledge of the Dewey decimal system, the Library of Congress, research paper orthodoxy, web searching, and the ability to set up an RSS feed. En route to his first mission, Flynn managed to decode the previously untranslated Language of the Birds in just over seven hours, a feat that no other Librarian (save one, who created the book) had been able to accomplish. Flynn rapidly evolves into a brave hero, not easily overwhelmed by the supernatural.
When Flynn was still quite young his father was shot by an unknown assailant. It took many years for Flynn to identify the murderer, and discover the reasons behind it. He took clarinet lessons when he was young, and when he was nine years old he attended a book signing of Stephen Hawking where he began to argue with Hawking about the correctness of the central thesis of the book.
His geeky bookishness is coupled with a razor-sharp wit that unfortunately has a habit of manifesting itself at the worst times. Flynn really hates being corrected. He is a bit awkward meeting women, as well as too busy globe-trotting and fighting evil to maintain a relationship, and so his mother is constantly trying to set him up on dates. By the end of the third movie he has embraced his destiny as the Librarian.
