The Neo Warriors were designed by Praetorius to do the dirty work for the Neosapiens. Neo Warriors were the least humanoid of all Neosapien broods, combining features of different animals from Earth (raptors, crabs, eagles, bats, etc.) with some rather unusual abilities like acidic saliva, which could dissolve even the strongest alloys. With the invention of Neo Warriors and later, the Neo Lords, mainstream Neosapiens were freed from the obligation to serve in the ground forces and could concentrate on piloting E-frames. There have been a total of three generations of Neo Warriors, each smarter and deadlier than the previous.
