Tom Perkins has shown off some of his old, unused concept art for Nemetrix predators on his Twitter. According to him, the predators has no designated prey as he was just playing around with the ideas while discussing it with Glenn Murakami and the late Dwayne McDuffie during the early production stages of Ben 10: Omniverse. Its interesting to note that none of the early predators had Nemetrix symbols or collars.
