In that capacity, he and his aide conducted an inspection of the USS Enterprise after its return from a battle with the USS Reliant, which had been commandeered by Khan Noonien Singh. It was during this inspection that Morrow informed James Kirk and his crew that the Enterprise was going to be decommissioned.
Later, Kirk pled with Morrow for permission to take the Enterprise back to the Genesis planet in an effort to reunite Spock's katra with his body, a request which Morrow denied, explaining that Genesis had been quarantined.
After Kirk and his bridge crew had clandestinely repaired the Enterprise and attempted to steal it from Earth Spacedock, Morrow hailed Kirk on the emergency channel and ordered him to surrender the Enterprise. Kirk offered no reply. (Star Trek III: The Search for Spock)
Admiral Morrow was portrayed by Robert Hooks. Morrow was the only Starfleet admiral to be referred to by the title of "the Commander of Starfleet." He was intended to reprise the role in Star Trek IV: The Voyage Home, but the role of Starfleet Commander was later replaced with the role of Admiral Cartwright.
According to the script notes, Morrow was described as "a distinguished looking black man" and that he and Kirk have together shared "twenty-five years of comrade-ship, service and sacrifice." The first draft script gave his middle initial as G. The script also gave his first name as Harry.
