Ensign Pridemore was a Starfleet security officer assigned to the Federation starship USS Lexington in the late 2350s. Pridemore was partnered with Ensign Moytulix to serve as an honor guard detail to escort a shuttlecraft carrying Eric Stiles aboard ship for a ceremony honoring Stiles's years spent as a prisoner of the Pojjana. Pridemore took the opportunity to tell Stiles that he was tremendously honored to be part of the honor detail, and referred to him as "sir" despite the two being of the same rank.
