- "Go forth, and do what you must."
- —Stephen D. Kenny
The first person in Earth history to break the speed of light. A former Federation air force pilot, he personally volunteered for the dangerous manned test flight for Professor Trillas Bachtein's warp drive, and he successfully carried out a faster-than-light warp in an A.D 2087 experiment, a feat long dreamed of by all mankind. The experiment made clear numerous issues with manned warping, and was a great leap forward in mankind's pursuit of the vast expanse of space. His exploits earned him the nickname "Lightspeed Kenny," and instantly made him one of the era's most iconic heroes. This event lead him to obtain the appointment as commander of the USTA's moonbase, overseeing space development and administration while offering behind-the-scenes support and inspiration for the SRF's efforts. It was during these events that an unknown force, later revealed to be Phantoms, attacked and destroyed Eldar, the Eldarian homeworld. These Phantom ships had the design of SRF ship, resulting in the Eldarians indicting Earth responsible. In order to prevent an intergalactic incident, the USTA officially denied that any such organization, known as the SRF, ever existed.
At this point in time, Commander Kenny was charged with erasing all traces of said organization, reluctantly accepting the order from Deputy Director Shimada. Soon thereafter, Kenny's ship would run into the SRF-003 Calnus, relaying the grave news. Edge Maverickand his crew in turn relay their own equally grave news, about the Phantoms. Letting them go after their unanimous consensus to move forward. However, this now presents a problem of how to explain this to his superiors. It baffles him until Heinz thoroughly explains the 'contradicting loophole' within their order: how could they destroy SRF's ships, if the SRF did not exist?
Later on, in the midst of the Morphus assault on Nox Obscurus, he arrives along with Supreme Commander Gaghan and a combined Earth-Eldarian fleet. They lend aid, allowing the Calnus to proceed towards the planet and bolster their beleaguered allies.
After the battle, Stephen Kenny was influential to the formation of theTerran Alliance, becoming its first president, and establishing the Underdeveloped Planet Preservation Pact.
