Roy Dunsel

Roy Dunsel was a Human male Earth Starfleet officer in the 22nd century.

History
He commanded Earth's third starship, the  Challenger.

In March 2156, the Challenger and the USS Yorktown (NCC-108) visited the planet Andoria. Dunsel invited Yorktown's CO, Captain Ketai Shosetsu for a tour and a dinner aboard Challenger. In the middle of the dinner, his communications officer Ensign Hendricks contacted him about a cascading pattern of node failures in Andoria's warp detection grid.

This foreshadowed a Romulan attack. In the unfolding battle, the Romulan warbird Dhivael took control of Challenger and Dunsel was killed during a fire fight that forced the Romulan forces to retreat from the Challenger.
