The recurring character did not have a set identity until Scott referred to him as "Roger" in , the same first name as Holloway. Kirk addressed him clearly as "Mister Lemli" in  (though Paramount+ closed captioning stated "Mr. Norman") and , although the captain referred to him less clearly in , something more akin to with "Mister Mulney" (as indicated in the Paramount+ subtitles) or "Mister Mellway" (according to the Netflix subtitles). Kirk referred to him just by rank, "Ensign", in .

According to the , Lemli was a reference to the daughters of William Shatner and his production company Lemli Music. The name was a combination of the first names of Shatner's three daughters: Leslie, Melanie and Lisabeth. Shatner later chose "LEMLI" for his vanity license plate in California.

Lemli was named Joe Reinhart in the novel , which adapts the ending of "That Which Survives".
