As mentioned previously, Nidoqueen and Nidoking are considered the male and female forms of each other despite being completely different species. They are depicted as larger and a bit more imposting to the rounder design of Nidoqueen, sporting more spines and sharp fangs across its jaw.

Much like Nidoqueen, the final evolution of this line drops most semblance of rabbits in lieu of large, kaiju-like monsters. It looks more monstrous while having elements of rhino and porcupine. It does retain its rabbit origins in its ears and the moon rabbit theming of using a moon stone.
