Flint is the codename for Dashiell R. Faireborn. Flint was a warrant officer on the original G.I. Joe series and was one of the highest men on the chain of command. Later he would be romantically linked with Lady Jaye. It was confirmed on the 20th Anniversary Transformers DVD release that Flint and Lady Jaye had a child together, which was Marissa Fairborne who appeared on the Transformers Series.
Flint did not appear on the DiC series, Sigma Six (although he did have an action figure for that series), or the recent G.I. Joe video Game. He did however appear on three parts of the G.I. Joe Resolute series, in which Charlie Adler supplied the voice as well as the Valor vs Venom and Spy Troops projects where Brian Dobson took on the role. Finally, he has made an appearance, voiced by his original voice actor Bill Ratner on both Family Guy and Robot Chicken.
