Shade stalker was a predatory species living on the planet Odessen. Bipedal and covered in scales, they were extremely aggressive in nature, often hunting in packs. Bizzarely, when Doctor Juvard Illip Oggurobb studied the species, he was unable to determine their diet, as they did not consume the flesh of their kill or seemingly anything at all. Citing their defensive scales, Oggurobb theorized that the species rapidly evolved through an unknown process, possibly related to the Force.
