After evolving and standing upright, Rhydon gain a large boost to their intelligence. They are massive and powerful creatures, capable of physically overpowering almost any other Pokemon in the Kanto region. However, they are still very weak to special attacks. Matching their imposing physique is their genitalia; a male's penis can easily grow past 2 feet, and their heavy testicles produce a huge amount of sperm. Any Pokemon on the receiving end of a mating Rhydon will be stretched to their limit.
