The Fenrisal were a humanoid civilization that belonged to the Breen Confederacy. The helmet designs mandated by the Confederacy included a snout to accommodate their biology.
In the year 2375, Ezri Dax speculated that the Breen had a wolf-like appearance. As Julian Bashir and Sarina Douglas later discovered, the Fenrisal were indeed lupine in appearance: one, Chon Min, was described as having golden-colored fur and thick, but dexterous, paw-like hands. (DS9 episode: "Strange Bedfellows"; ST - Typhon Pact novel: Zero Sum Game)
Berro was a Fenrisal individual, as were Roje and Tren. (TNG - Cold Equations novel: Silent Weapons)
- The Fenrisal were likely named after the Fenrir, or Fenris wolf, of Norse mythology.
