Shelgon is a Dragon-type Pokémon introduced in the third generation of the Pokémon series. It evolves from Bagon starting at level 30 and is known for its protective shell, which helps it develop its strength and resilience. Shelgon is characterized by its round, armored body and a tough exterior that shields it from attacks. It is known to be a stage in the evolutionary line that leads to Salamence, a powerful Dragon-type Pokémon. Shelgon primarily focuses on building its power before it evolves into its final form.
