Bagon is a Dragon-type Pokémon introduced in Generation III.
It evolves into Shelgon starting at level 30, which evolves into Salamence starting at level 50.
Bagon lives in rough terrains with cliffs and rocks. It longs to fly and jumps off cliffs trying to be able to do so. Frustrated at its inability to fly, it leaps off cliffs and smashes its head against large rocks indiscriminately. This process of continually bashing its head causes it to become as hard as steel. Well-developed neck muscles support its hard head. This, combined with its powerful body, allows it to shatter rocks with its head. Bagon is known to be rather solitary, preferring not to form groups with others of its kind. It has been theorized that Bagon's habit of head-bashing and pure belief influences the cells needed to help it evolve.
