Read more ↓Steelix is a formidable Steel/Ground-type Pokémon, introduced in Generation II as the evolved form of Onix. This massive iron snake is known for its incredible durability and immense power, often found deep underground, where it carves tunnels through solid rock and consumes boulders to further harden its body. Its diet consists primarily of rocks and minerals, which it grinds with its powerful jaws, contributing to its already impressive resilience. Steelix is a solitary creature, preferring the dark, subterranean environments where it can roam undisturbed. In the Pokémon games, it is a popular choice for its high defense and attack stats, making it a reliable tank in many teams. In the anime, Steelix has made several memorable appearances, notably Brock's Steelix, which showcased its unwavering loyalty and strength. Its unique typing gives it several resistances, though it is particularly vulnerable to Fire and Water attacks. Culturally, Steelix embodies resilience and strength, a testament to enduring hardship and emerging even stronger. Its evolution from Onix, a much lighter rock snake, symbolizes a profound transformation and adaptation to a more robust, metallic form, making it a fan favorite for its unique design and imposing presence.
