Shelgon

Shelgon (Japanese: コモルー Komoruu) is a Dragon-type Pokémon introduced in Generation III. It evolves from Bagon starting at level 30 and evolves into Salamence starting at level 50. Shelgon is a quadrupedal Pokémon that resembles a pupal stage. It has a bony shell covering its body with two openings, one in the front revealing its yellow eyes, and the other in the back. This shell protects it from attacks but makes it heavy and sluggish. Shelgon hardly eats as it prepares to evolve. Inside its shell, its body is transforming. Once it evolves, the shell peels off. Shelgon can be found in caverns, where it remains still until evolving. In the anime, Shelgon debuted when a Bagon evolved in "Let Bagons Be Bagons!" and was also used by Drake of the Hoenn Elite Four.
