- "It is said that the species was nonviolent and grazing before being corrupted by Sith alchemical experiments that awakened a latent part of their brains and changed them into unnatural abominations. Random mutations now occur that produce some tuk'ata that can live for centuries and grow to immense proportions."
- ―In-game Codex (Bestiary)
The Tuk'ata, also known as Sith hounds, are a race of vertebrate animals native to the planet Korriban. Tuk'ata have three rows of teeth, sharp claws and horns. They are unusually intelligent and capable of communicating with one another. They can recognize Force-users and attack them with ferocity. These creatures were once bred for training purposes, but have long since become guardians for the old tombs on Korriban. During the Cold War, the Tuk'ata were used for researching the Force and it's capabilities by a Sith Master named Renning.
