This character first appeared on Hero Factory FM during an interview with DJ Mak Megahertz. Along with his partner Deuce Carter, Flint has had a history of great missions. During the show Mak refers to his missions as some of the greatest ever broadcast, especially one that was played on the air involving the defeat of a creature called the Sun Eater where he coined the phrase "Sucks to be him right now!"
Later on in the show Flint and Carter are asked about their team leader Thelonius Fox who is apparently nowhere to be found. Later on, Mak ends the show by playing a mission broadcast many years ago on a station known as the Galactic Federation as they rescued the King of Saturn from the hideous Gorgon of Neptune. When asked if he missed fighting in the old days, Flint agreed wholeheartedly. After the segment of the team easily defeating the Gorgon the interview was over.
It is revealed from these two heroes that long ago, perhaps when Hero Factory just started, that missions were broadcast openly to civilians. The network that showed these events were known as the Galactic Federation which resembles old televised advertisements (especially for that of the army or a documentary) from Earth during the early 1900s. Whether this program is still around is uncertain since reporters like Zed Clickstart are needed to interview heroes on mission, but clearly the interest in learning about HF missions is still strong within those who respect Hero Factory.
Mak Megahertz appeared to recognize Deuce Carter, Oscar Flint, and Thelonius Fox well enough and unlike many of his other interviews he treats these heroes with respect. Clearly this hero team is one of the more popular ones among those who grew up under the protection of Hero Factory.
