Horaxes are massive blue skinned reptilian creatures that are native to the frigid planet of Nelvaan and one appeared in the 2003 Legends animated micro series Star Wars: Clone Wars.
One Horax appeared in the series, where it attacks Anakin Skywalker, Obi Wan Kenobi, and the clone troopers. It kills most of the troopers, but was killed by Skywalker. This causes a young Nelvaanian boy furious over the interruption of his ritual.
- Some of the sounds of the Horax before its death were burrowed from the T-rex's sounds from Jurassic Park.
