Nupperibo are one of the lowest forms of Baatezu, the lawful evil fiends of Baator. Only one step above the lemure, they look similar, with gelatinous flesh covering their bodies, and act similar too, since they are also practically mindless. In the Blood War though, where their lower cousins are used as cannon fodder, the nupperibo are trained to form fearsome battle waves to wash over opponents.
