Nidorino

This is the second stage of evolution for the male Nidoran. Nidorano is an aggressive Pokemon that is quick to attack, and the horn on its head secretes a very powerful venom. If the Pokemon League could find a Nidorino in the wild to study, numerous questions would be answered, like, "Do the Nidorino's spikes shed when it evolves, or does the Nidorino's poison work on other Nidorino?" These are questions we may never know the answer to.

First appearance: Ash has not yet encountered a Nidorino
