Mordock was a gifted Benzite who competed with Wesley Crusher for a place at Starfleet Academy and won it.
Mordock was a Benzite candidate who sat the Starfleet Academy entrance examination alongside Wesley Crusher on Relva VII in Coming of Age. He was highly talented, and during one part of the test Wesley helped him solve a difficult problem so that both could advance.
When the results were announced, Mordock was the one chosen for admission, and Wesley was encouraged to try again the next year. Mordock thanked Wesley for his help and wished him success. Wesley later mistook another Benzite, Mendon, for him in A Matter of Honor. John Putch played him.
