| Raging Rhydon
Raging Rhydon (Japanese: VSサイドン VS. Sidon) is the seventh round in the Red, Green & Blue chapter of the Pokémon Adventures manga.
Red and Misty are at the Mt. Moon entrance hiding in some bushes from the Team Rocket Grunts. They all have the same purpose, to find the Moon Stone, a rock with a moon-shaped inscription that can enhance a Pokémon's power. They enter the caves, but it is too dark to see anything. Red sends out Pika to illuminate the cave, and the darkness is no longer a problem. Suddenly, Red collides with a Rhyhorn, one that belongs to Team Rocket! The Grunts, along with Koga, surround them, and Red challenges Koga to a battle.
Rhyhorn begins with Rock Throw, managing to bury Pika, only for Pika to recover and fire a blast of electricity, surrounded by electrified debris from Rock Throw. The attack successfully knocks out Rhyhorn, but then Koga injects a liquid that forces Rhyhorn to evolve into Rhydon. Misty realizes that her Gyarados was similarly abused, and furious at Koga's nonchalant attitude she attacks the newly evolved Rhydon with her Staryu. Unfortunately, the attack is returned by Horn Drill, pushing Misty against the cave wall and causing her to faint. Rhydon stomps on Pika before moving in to finish Red, but Pika slides out from underneath Rhydon having charged itself tremendously. Using its tail, Pika cuts off a huge portion off the cave roof, blocking the cave and allowing Red a chance to escape with the others.
Outside the cave, Misty regains consciousness, while Red reveals that he pocketed the Moon Stone after Pika collapsed the cave.
- The evolution of Koga's Rhyhorn into Rhydon is the first evolution shown in the manga; the Pokémon doesn't glow like in the games or anime, it just transforms.
