The Drengir (pronounced /dʒɹɛnˈɡɪər/) were a species of sentient, amorphous plant-like carnivores who threatened to reap harvest across the Galactic Frontier in the aftermath of the Great Disaster during the High Republic Era. The Drengir had numerous tentacles as well as an array of teeth. Although they lacked the scheming nature and power structure of the anarchistic Nihil marauders, the Drengir were a danger to the galaxy and the Jedi, and one Jedi had their fate inescapably linked to the creatures.

With an aptitude for healing, the Drengir were largely impervious to the scorches of blasters and singes of lightsabers; when seared in half by the blade of a lightsaber, a Drengir could simply reform with two animated bodies. Reflecting numerous hues of green, the Drengir could corrupt individuals into joining with their collective mind, which was bent on only one purpose: to consume life.
