Flynn obtained the writing position on the comic by sending in unsolicited proposals, after a long participation in unofficial creation of comics about Sonic. He is notable for being a rare case of making a transition from active amateur to pro.
He has not only been active with the fan community since his hiring at Archie Comics, but even prior to that with the now defunct site TSIC (The Sonic Info Center). He gained initial recognition for a fan comic known as Other M. His stories contain heavy usage of prior continuity and returning characters. One of his focuses seems to be guiding the comic to better fit in with Sega's games while still retaining the best elements of the comic's original material.
Ian Flynn is currently the head writer for two of Archie's comics: Sonic the Hedgehog, Sonic Universe and was the main writer for Mega Man, Sonic Boom, and New Crusaders.
- He and Tracy Yardley joined Archie Comics at the same time, that being Sonic the Hedgehog #160.
- In an interview in Sonic Super Special Magazine #1, Flynn stated that his influences as a writer are "Shakespeare, Stephen Crane, Kurt Vonnegut, E. E. Cummings, Chris Claremont, Robert Kirkman, Brian M. Bendis, Mark Miller, Dr. Seuss, Jeff Smith, Don Rosa and so many more."
