Steelix

Steelix is a formidable Steel/Ground-type Pokémon introduced in Generation II as the evolved form of Onix. This massive Iron Snake Pokémon is known for its incredibly hard body, said to be tougher than any metal, a result of the immense pressure and heat it endures deep underground. Steelix typically inhabits subterranean caverns and mines, where it burrows through solid rock with ease, often creating vast tunnel systems. Its diet consists primarily of minerals and rocks, which it grinds down with its powerful jaws. In the games, Steelix is a defensive powerhouse with high Defense and Attack stats, making it a valuable asset in many teams. It plays a memorable role in the anime, most notably as Brock's signature Pokémon, evolving from his Onix. Culturally, Steelix embodies resilience and strength, a testament to the harsh environments it thrives in, and its imposing design has made it a fan favorite among those who appreciate powerful, sturdy Pokémon. Its unique type combination gives it resistances to many common types, though it has notable weaknesses to Fire, Water, Fighting, and Ground.
