Rhydon

Rhydon is the second and final evolutionary stage for Rhyhorn. Protected by an armor-like hide, it is capable of living in 3,600-degree molten lava. In "Riddle Me This," our friends find themselves face to face with Blaine, the riddling Pokemon gym trainer from Cinnabar Island. In a fiery conflict, Ash chooses Charizard to battle Blaine's super-tough Rhydon. When Charizard ignores Ash and flies out of the arena, Rhydon wins the match without even battling!
