Nidoking, Known as the Drill Pokémon, are a fully grown and developed species of male possum-like Pokémon and the final stage in the Nidoran ♂ evolutionary line. Its horn is hard enough to pierce a diamond and contains secreted venom, making it a powerful stabbing tool upon prey and Pokémon battle opponents. Nidoking have immense upper-body strength, being able to snap a telephone pole like a dry twig. It uses its tail to smash down its target, then constrict it to break its bones. Its thick tail packs enormously destructive power capable of felling a metal transmission tower. Once a Nidoking goes on a rampage, nothing can be done to stop it. There are far fewer Nidoking than Nidoqueen in the anime. They serve as leaders of herds, with multiple Nidoqueen mates.
