Chalnoth

The Chalnoth were a humanoid species with cranial ridges, manes, and hook-like teeth. They lived in a warlike state of anarchy favouring the strong. The Chalnoth could only eat raw or living meat and some individuals could only survive for four days without food.

Data, son of Soong
In an alternate timeline where Data was rescued by the Klingon Defence Force and raised in the Klingon Empire, a group of Chalnoth pirates had built several Daedalus class starships with up-to-date weapons and shields, and salvaged Avenger (NX-09) and the USS Enterprise (NCC-1701-B). They used this fleet to raid the Yattho, a precognitive race who predicted the attack and invited the KDF to test their new IKS Vor'cha in battle against the Chalnoth. The result was a great victory for the Yattho and the KDF, and confirmation that the Vor'cha class attack cruiser was a viable type of starship.(Data, son of Soong)
