Fralkoni

The Fralkoni (pronounced "frahl-KOH-nee") are a race who threatened Noel Turner and his crew at least once in the past. Starfleet consider them a hostile race. It's uncertain when or where Noel Turner and the Fralkoni had a run-in or how many times, but with their mention in Counselor Leslie Hernandez's profile of him, we would assume his dealings with them were more than once or even frequently.
