In 2268, Fitzroy was assigned to accompany a survey team that traveled to the tropical planet Tau Omega III aboard the Copernicus, which crashed after being disabled by the electromagnetic pulse of a solar flare.
When the crew encountered a group of winged Tau Omega III harpies, he reacted to a threatening move by drawing his phaser. One of the harpies flew over the whole group and landed behind Fitzroy, then sliced his arm open with its talons. Fitzroy rammed his shoulder into the harpy's back, and a brawl ensued. A rescue party materialized close by, which startled the harpies, and they hastily retreated. (TOS - FASA RPG short story: "Planetfall")
