Tarsarian devourers were predatory creatures of Taris's ruined landscape, lacking sentience. These beings emerged during the Cold War, the result of a rakghoul virus evolving within the tarsarian stomper.
Originally zoo inhabitants, the stompers were foreign animals that initially prospered within Taris's jungles following the planet's destruction. However, they were eventually surpassed by their infected and far more ferocious relatives. Despite the fact that these creatures could not transmit the rakghoul plague, the devourers rose to become the dominant and most dreaded species on Taris, reigning supreme as the planet's apex predators.
