Nexus are agile hunters, with lightning quick reflexes and well-refined predatory instincts. In the wild, they spend most of their time swinging through the treetops in search of bark rats or arboreal octopi, their preferred prey. When a meal is spotted, the hunter runs them down and strikes swiftly, weakening the opponent and then grasping their head in its wide mouth and thrashing to break the neck. Though capable of extremely quick movements when striking, they are known to tire easily in prolonged fights.
Despite their ferocity, Nexus can be found far from their homeworld as exotic pets or watch-beasts. Many would-be beast trainers discover that the creature is too aggressive and too easily irritated to be easily tamed for guard duty. As a result, most Nexus in captivity are kept wild and used in arena battles where their wicked temperament is appreciated and even encouraged.
