Shade stalkers were a type of predatory species that inhabited the planet Odessen. These scaled, bipedal creatures displayed extreme aggression, typically hunting their prey in groups. Interestingly, when Doctor Juvard Illip Oggurobb researched them, he could not ascertain what they ate, since they did not eat the meat of the animals they killed, or anything else apparently. Oggurobb suggested that the species underwent rapid evolution via an unconfirmed mechanism, potentially connected to the Force, pointing to their protective scales as evidence. During Vaylin's Assault on Odessen, the fighting forced many Shade Stalkers into the open, leading them to attack members of both the Alliance and the Eternal Empire.
